Measuring impact of protected area management interventions: current and future use of the Global Database of Protected Area Management Effectiveness

Private management of African protected areas improves wildlife and tourism outcomes but with security concerns in conflict regions

Protected areas can conserve wildlife and benefit people when managed effectively. African governments increasingly delegate the management of protected areas to private, nongovernmental organizations, hoping that private organizations' significant resources and technical capacities actualize protected areas' potential. Does private sector management improve outcomes compared to a counterfactual of government management? We leverage the transfer of management authority from governments to African Parks (AP)-the largest private manager of protected areas in Africa-to show that private management significantly improves wildlife outcomes via reduced elephant poaching and increased bird abundances. Our results also suggest that AP's management augments tourism, while the effect on rural wealth is inconclusive. However, AP's management increases the risk of armed groups targeting civilians, which could be an unintended outcome of AP's improved monitoring and enforcement systems. These findings reveal an intricate interplay between conservation, economic development, and security under privately managed protected areas in Africa.

Introducing Elinor for monitoring the governance and management of area-based conservation

Monitoring the governance and management effectiveness of area-based conservation has long been recognized as an important foundation for achieving national and global biodiversity goals and enabling adaptive management. However, there are still many barriers that prevent conservation actors, including those affected by governance and management systems from implementing conservation activities and programs and from gathering and using data on governance and management to inform decision-making across spatial scales and through time. We explored current and past efforts to assess governance and management effectiveness and barriers actors face in using the resulting data and insights to inform conservation decision-making. To help overcome these barriers, we developed Elinor, a free and open-source monitoring tool that builds on the work of Nobel Prize winner Elinor Ostrom to facilitate the gathering, storing, sharing, analyzing, and use of data on environmental governance and management across spatial scales and for areas under different governance and management types. We consider the process of codesigning and piloting Elinor with conservation scientists and practitioners and the main components of the assessment and online data system. We also consider how Elinor complements existing approaches by addressing governance and management in a single assessment at a high level for different types of area-based conservation, providing flexible options for data collection, and integrating a data system with an assessment that can support data use and sharing across different spatial scales, including global monitoring of the Global Biodiversity Framework. Although challenges will continue, the process of developing Elinor and the tool itself offer tangible solutions to barriers that prevent the systematic collection and use of governance and management data. With broader uptake, Elinor can play a valuable role in enabling more effective, inclusive, and durable area-based conservation.

Nature Forest Reserves in Tanzania and their importance for conservation

Since 1997 Tanzania has undertaken a process to identify and declare a network of Nature Forest Reserves (NFRs) with high biodiversity values, from within its existing portfolio of national Forest Reserves, with 16 new NFRs declared since 2015. The current network of 22 gazetted NFRs covered 948,871 hectares in 2023. NFRs now cover a range of Tanzanian habitat types, including all main forest types-wet, seasonal, and dry-as well as wetlands and grasslands. NFRs contain at least 178 of Tanzania's 242 endemic vertebrate species, of which at least 50% are threatened with extinction, and 553 Tanzanian endemic plant taxa (species, subspecies, and varieties), of which at least 50% are threatened. NFRs also support 41 single-site endemic vertebrate species and 76 single-site endemic plant taxa. Time series analysis of management effectiveness tracking tool (METT) data shows that NFR management effectiveness is increasing, especially where donor funds have been available. Improved management and investment have resulted in measurable reductions of some critical threats in NFRs. Still, ongoing challenges remain to fully contain issues of illegal logging, charcoal production, firewood, pole-cutting, illegal hunting and snaring of birds and mammals, fire, wildlife trade, and the unpredictable impacts of climate change. Increased tourism, diversified revenue generation and investment schemes, involving communities in management, and stepping up control measures for remaining threats are all required to create a network of economically self-sustaining NFRs able to conserve critical biodiversity values.

How effective are protected areas for reducing threats to biodiversity? A systematic review protocol

BACKGROUND

Protected areas (PAs) have become one of the most important instruments to preserve nature and, when effective, can significantly reduce human pressure and derived threats to biodiversity. However, evidence suggests that despite the growing number and coverage of PAs worldwide, biodiversity trends continue to deteriorate, and human pressure increases outside and inside PAs. While many studies have focused on the effectiveness of PAs in maintaining ecological features, less attention has been given to the threat reduction potential of PAs, despite threats being one of the main factors leading to the need to conserve biodiversity. It is therefore essential to understand PAs' role in addressing threats. In this paper, we describe the protocol for conducting a systematic review to explore and review the evidence surrounding the effectiveness of PAs as an intervention to reduce threats to biodiversity. We will examine the role of PAs in addressing several types of threats. Thus, our primary research question is: How effective are protected areas for reducing threats to biodiversity?

METHODS

This protocol follows the Collaboration for Environmental Evidence guidelines for evidence synthesis and complies with the ROSES (Reporting Standards for Systematic Evidence Synthesis) reporting framework. We will use a comprehensive search, covering databases such as Web of Science-core collection and Scopus and organizational websites to capture relevant grey literature. Our search terms and strategies aim to find studies assessing change of threats given in PAs at any scale and ecosystem type capturing literature in English. Independent reviewers will screen search results at the title-abstract, and full text levels. In order to evaluate the relevance of the evidence, we will use the Collaboration for Environmental Evidence Critical Appraisal Tool. The results will be presented as a narrative synthesis supported by quantitative data. Additionally, a meta-analysis, if possible, will be performed.

Participation in protected area governance: A systematic case survey of the evidence on ecological and social outcomes

Protected areas are considered key to conserving ecosystems and safeguarding biodiversity worldwide. Local stakeholders' involvement in decision-making in area-based conservation approaches may help to mitigate environmental inequalities and to improve social and ecological outcomes. However, sound and in-depth evidence on the relationship between participation and protected area outcomes is piecemeal. To synthesize the available knowledge, we provide evidence from a systematic literature review of 52 empirical case studies from the scientific literature examining the social and ecological outcomes of protected-area-related decision-making processes in which local stakeholders participated. In a first step, we defined factors that are linked to social and ecological protected area outcomes as success. Based on these factors, we then categorized success indicators which we quantitatively linked to features of participation. Our review provides evidence of the relationship between protected area successes and the following four features of participation: 1. Genuine devolution of power to the local level; 2. Involvement of diverse actors and multiple perspectives through fair and inclusive processes; 3. Long-term external support; 4. Devolution of rights. Even though the degree and form of participation require adjustment to specific local contexts, this overview of features provides sound evidence based on the relation between participatory decision-making and social and ecological effectiveness in protected areas. These insights can be used to design more effective participatory conservation interventions that meet both biodiversity conservation and human well-being.

The cost of not acting: Delaying invasive grass management increases costs and threatens assets in a national park, northern Australia

Globally, invasive grasses are a major threat to protected areas (PAs) due to their ability to alter community structure and function, reduce biodiversity, and alter fire regimes. However, there is often a mismatch between the threat posed by invasive grasses and the management response. We document a case study of the spread and management of the ecosystem-transforming invasive grass, Andropogon gayanus Kunth. (gamba grass), in Litchfield National Park; an iconic PA in northern Australia that contains significant natural, cultural and social values. We undertook helicopter-based surveys of A. gayanus across 143,931 ha of Litchfield National Park in 2014 and 2021-2022. We used these data to parametrise a spatially-explicit spread model, interfaced with a management simulation model to predict 10-year patterns of spread, and associated management costs, under three scenarios. Our survey showed that between 2014 and 2021-22 A. gayanus spread by 9463 ha, and 47%. The gross A. gayanus infestation covered 29,713 ha of the total survey area, making it the largest national park infestation in Australia. A. gayanus had not been locally eradicated within the Park's small existing 'gamba grass eradication zone', and instead increased by 206 ha over the 7-year timeframe. Our modelled scenarios predict that without active management A. gayanus will continue spreading, covering 42,388 ha of Litchfield within a decade. Alternative scenarios predict that: (i) eradicating A. gayanus in the small existing eradication zone would likely protect 18% of visitor sites, and cost ∼AU$825,000 over 5 years - more than double the original predicted cost in 2014; or (ii) eradicating A. gayanus in a much larger eradication zone would likely protect 86% of visitor sites and several species of conservation significance, and cost ∼AU$6.6 million over 5 years. Totally eradicating A. gayanus from the Park is no longer viable due to substantial spread since 2014. Our study demonstrates the value of systematic landscape-scale surveys and costed management scenarios to enable assessment and prioritisation of weed management. It also demonstrates the increased environmental and financial costs of delaying invasive grass management, and the serious threat A. gayanus poses to PAs across northern Australia.

Protected area management effectiveness and COVID-19: The case of Plitvice Lakes National Park, Croatia

The decline in economic activities and tourism during the COVID-19 pandemic has reduced the pressure on the environment and protected area (PA) systems to some extent. However, the financial losses within nature-based tourism due to travel restrictions and park closures will negatively impact tourism income-dependent PAs' management effectiveness. This exploratory study incorporates a risk-assessment framework to investigate and provide first insights into the pandemic's influence on the delivery of management outputs in Plitvice Lakes National Park, Croatia.

Although in 2020, this PA faced a 75% decline in overall revenue compared to the year before, analysis suggests that, in the short term, conservation-related outputs are least affected. Visitor management and PA efforts to support the local community's sustainable development are the most severely impacted first-order outputs. Third-order nature-based tourism-related outputs face average to high risks.

This study's risk-assessment framework provides a starting point for a post-pandemic reassessment of the delivery of PA management outputs and decision-making about output prioritisation and resource allocation. Results suggest several new avenues for research.

Management implications

Post-pandemic recovery of PA requires prioritisation risk framework to identify specific objectives that should be addressed first and which require additional effort or funding. Facing a crisis PA will allocate financial resources in a way that sustains primary functions such as conservation until negative trends change, or at least until financial resources become available. PAs require a paradigm shift, which includes tailoring of financial mechanisms to practical and policy purposes, effective allocation of financial resources, and responsible tourism recovery plans that capture the value and efforts of conservation through tourism and investments in nature-based solutions for sustainable tourism within PA.

Defining performance thresholds for effective management of biodiversity within protected areas

Performance thresholds are an important tool for determining successful conservation outcomes. They provide an objective means of defining good ecological condition and have been endorsed as an essential part of best practice in protected area (PA) management within the International Union for the Conservation of Nature Green List of Protected and Conserved Areas Standard. With a growing number of PAs attaining Green List status globally, thresholds developed by PAs on the Green List present an excellent resource with which to identify the attributes of well-defined performance thresholds. We examined 349 thresholds associated with PAs on the Green List to determine whether they were specific and measurable (i.e., factors recognized as essential for setting well-defined targets). We assessed whether thresholds were defined quantitatively and whether definitions included ambiguous terms (e.g., stable numbers). We identified six different ways thresholds were expressed and found that many thresholds were expressed as management objectives, rather than ecological condition thresholds, although this trend improved over time. Approximately one-half of the performance thresholds lacked the necessary specificity to delineate successful outcomes. Our results enabled us to develop a checklist of information required to set robust performance thresholds. Recommendations include that thresholds should be quantitatively defined, including quantitative estimates of the limits of acceptable change (LAC) around the target condition. To ensure transparency, a rationale and associated evidence should be provided to support the threshold and the LAC. When accompanied by a rationale and quantitative estimate of the current condition of the value, unambiguously defined thresholds with a quantitative LAC provide an objective means of demonstrating that successful conservation outcomes have been achieved. These recommendations will help conservation managers apply the Green List Standard and improve the measurement of conservation outcomes more broadly.

BREMi-A New Tool for the Evaluation of UNESCO Biosphere Reserve Management Effectiveness: Case-study in the Arab Man and Biosphere (ArabMAB) Regional Network

Scholars and practitioners have been striving to develop straightforward and effective tools to measure protected area management effectiveness (PAME). UNESCO Biosphere Reserves (BR), with their unique functional and zonation schemes are monitored according to their compulsory 10-year Periodic Review (PR), which is useful for UNESCO's evaluation purposes but lacks comprehensiveness and utility for adaptive management. Based on existing PAME methodologies, we develop and propose the first quantitative tool for the evaluation of BR management effectiveness, that would enhance and complement the currently used qualitative PR report, and serve the rapid evaluation needed for BR managers to monitor, evaluate, and adapt their management approach to achieve the three functions of BRs. The tool consists of 65 indicators, embodied within the 6 elements of the World Commission on Protected Areas Framework. We then tested this tool, named Biosphere Reserve Effectiveness of Management index (BREMi) to evaluate management effectiveness across the Arab Man and the Biosphere Reserve network involving 17 BRs spanning 8 countries of the Middle East and North Africa. BREMi scores ranged from 4.43 to 8.65 (on a scale between 0 and 10), with a mean of 6.31 ± 1.040. All indicators were considered valuable measures of progress by our respondents, as well as by independent experts. We discuss our findings in light of available literature concerning the Arab region and through the conceptual frames of adaptive management and resilience. Finally, we discuss where the BREMi tool would be most useful for BR management authorities in the iterative process of evaluation and adaptive management.

Analysis of differences and commonalities in wildlife hunting across the Africa-Europe South-North gradient

Hunting and its impacts on wildlife are typically studied regionally, with a particular focus on the Global South. Hunting can, however, also undermine rewilding efforts or threaten wildlife in the Global North. Little is known about how hunting manifests under varying socioeconomic and ecological contexts across the Global South and North. Herein, we examined differences and commonalities in hunting characteristics across an exemplary Global South-North gradient approximated by the Human Development Index (HDI) using face-to-face interviews with 114 protected area (PA) managers in 25 African and European countries. Generally, we observed that hunting ranges from the illegal, economically motivated, and unsustainable hunting of herbivores in the South to the legal, socially and ecologically motivated hunting of ungulates within parks and the illegal hunting of mainly predators outside parks in the North. Commonalities across this Africa-Europe South-North gradient included increased conflict-related killings in human-dominated landscapes and decreased illegal hunting with beneficial community conditions, such as mutual trust resulting from community involvement in PA management. Nevertheless, local conditions cannot outweigh the strong effect of the HDI on unsustainable hunting. Our findings highlight regional challenges that require collaborative, integrative efforts in wildlife conservation across actors, while identified commonalities may outline universal mechanisms for achieving this goal.

Hunting and its impacts on wildlife are typically studied regionally, with a particular focus on the Global South. An assessment across a contrasting South-North gradient reveals differences in the ecological, social, and economic dimensions of hunting, but also identifies commonalities that point to general ways to reduce unsustainable hunting.

Assessing representation of remote sensing derived forest structure and land cover across a network of protected areas

Protected areas (PA) are an effective means of conserving biodiversity and protecting suites of valuable ecosystem services. Currently, many nations and international governments use proportional area protected as a critical metric for assessing progress towards biodiversity conservation. However, the areal and other common metrics do not assess the effectiveness of PA networks, nor do they assess how representative PA are of the ecosystems they aim to protect. Topography, stand structure, and land cover are all key drivers of biodiversity within forest environments, and are well-suited as indicators to assess the representation of PA. Here, we examine the PA network in British Columbia, Canada, through drivers derived from freely-available data and remote sensing products across the provincial biogeoclimatic ecosystem classification system. We examine biases in the PA network by elevation, forest disturbances, and forest structural attributes, including height, cover, and biomass by comparing a random sample of protected and unprotected pixels. Results indicate that PA are commonly biased towards high-elevation and alpine land covers, and that forest structural attributes of the park network are often significantly different in protected versus unprotected areas (426 out of 496 forest structural attributes found to be different; p < 0.01). Analysis of forest structural attributes suggests that establishing additional PA could ensure representation of various forest structure regimes across British Columbia's ecosystems. We conclude that these approaches using free and open remote sensing data are highly transferable and can be accomplished using consistent datasets to assess PA representations globally.

Assessing national-level provision of conservation capacity building: lessons learnt from a case study of Kenya

As global environmental pressures grow, the need for delivering relevant and sustainable capacity building in conservation has never been greater. Individuals, organizations and communities need the skills, knowledge and information that allow them to address environmental issues at a variety of spatial scales and in diverse contexts. Capacity is currently built through a range of activities, including tertiary education, training courses, online learning, mentoring and continuing professional development. However, a significant proportion of the current capacity-building provision is non-strategic, project-based and reactive. The conservation sector still lacks a coordinated approach to capacity building linked to broader conservation goals. Without an assessment of current capacity-building provision and future capacity needs, the delivery of capacity building in conservation will remain fundamentally ad hoc. The need for strategic conservation capacity building in sub-Saharan Africa has been identified and here we report on the first collation of online material to assess current conservation capacity provision in Kenya (the country with the greatest online capacity-building presence). We reviewed a total of 177 capacity-building initiatives delivered during 2014–2019 and recorded 55 separate metrics for each initiative. We present: (1) a broad overview of the data collation methods developed, (2) examples of data that will support strategic capacity-building strategies, and (3) the lessons learnt from this assessment.

Evaluation of the management of marine protected areas. Comparative study in Costa Rica

Costa Rica is one of the most biodiverse countries in the world, and stands out for its commitment to conservation. Along its two coasts, it presents a great heterogeneity of ecosystems and social realities. Social factors, more than physical-natural factors, determine the success or failure of an MPA, so they must be urgently incorporated into all phases of MPA management. The objective of this work is to analyze the management of three marine protected areas, to establish improvements. These areas are Santa Rosa National Park, Marino Ballena National Park and Cahuita National Park. The methodology used assesses 26 indicators grouped into 4 key factotres: management body, planning subprocess, public participation, and implementation subprocess. The results of this evaluation are 5 possible scenarios. These scenarios have been termed (from the ideal situation to the least favourable): proactive (1), learning (2), interactive (3), centralized (4) and formal (5) management. The results of this study show that both Santa Rosa and Cahuita present a proactive scenario (1), with high citizen participation, although in practice the way the two MPAs are managed is very different. Marino Ballena, on the other hand, is in scenario 5 (formal), and a series of measures are presented that can move it towards scenario 2 (learning). In general, MPA management in Costa Rica tends to be adaptive, with high public participation, as determined by its public policies. However, the existence of a public policy favors but does not guarantee success in MPA management, as can be seen in the difference in results. Therefore, the periodic evaluation of its management, allowing for feedback, is essential.

Ecotourism as a Resource Sharing Strategy: Case Study of Community-Based Ecotourism at the Tangkahan Buffer Zone of Leuser National Park, Langkat District, North Sumatra, Indonesia

The local community is an essential and key partner in managing protected areas, especially for national parks in Indonesia. Therefore, there is a need to establish adaptive collaborative management (ACM) between the park authorities and the local community. In 2000, several local leaders established a new organization to develop an ecotourism package called the Tangkahan Ecotourism Organization or Lembaga Pariwisata Tangkahan (LPT) and set up the Community Tour Operator to manage the ecotourism activities. Our study used a strengths, weaknesses, opportunities, and threats (SWOT) analysis through focus group discussions (FGDs), interviews with related stakeholders and key informants, and carried out a literature review. It was found that ensuring local community could generate alternative income from ecotourism was an effective way to protect the park from any illegal activities. Additionally, the results about sustainability from the FGDs show that all three categories: Social Process, Adaptive Natural Resource Management, and Impact/Condition are interrelated, meaning that the collaboration and adaptive management in Tangkahan have resulted in high levels of humanistic well-being and the maintenance of ecological values, supporting collaboration processes and adaptive levels. Finally, our study can be used as a basis for a model of national parks focusing on ACM.

Remote Sensing Based Conservation Effectiveness Evaluation of Mangrove Reserves in China

In recent decades, the mangrove area in China has changed dramatically, and governments have established multiple mangrove protected areas at various levels. However, we know little about the effectiveness of conservation on mangroves on a national scale. In this study, we constructed an evaluation index system for landscape health and proposed a landscape health composite index (LHCI) to characterize the landscape health status of mangroves. Based on the distribution dataset of mangrove forests mangrove in the recent 40 years, we evaluated the conservation effectiveness of mangrove reserves in China from a perspective of landscape health. The dynamics of mangrove areas show that the mangrove area in 83% of the reserves increased after the establishment of reserves. Additionally, the increase in mangrove area in provincial-level, municipal-level, and county-level reserves was higher than that in national-level reserves, and the most significant increase in mangrove area was in Guangxi, followed by Fujian and Hong Kong. The evaluation results show that mangrove reserves have achieved outstanding conservation effectiveness in China, with 43% of the reserves significantly improving the landscape health status of mangroves and 35% of the reserves maintaining good condition. The reserves in Guangxi, Guangdong, and Fujian Provinces showed more significant protective effects. Specifically, the most effective reserves protecting mangroves were the Qi’ao Island reserve, Maowei Gulf reserve, and Enping reserve. This study may provide references for formulating a rapid evaluation method of conservation effectiveness based on remote sensing and promote the scientific management of protected areas and the ecological restoration of mangroves in China.

Identification of Conservation Priority Areas and a Protection Network for the Siberian Musk Deer (Moschus moschiferus L.) in Northeast China

Species conservation actions are guided by available information on the biogeography of the protected species. In this study, we integrated the occurrence data of Siberian musk deer (Moschus moschiferus L.) collected from 2019 to 2021 with species distribution models to estimate the species' potential distribution in Northeast China. We then identified conservation priority areas using a core-area zonation algorithm. In addition, we analyzed core patch fragmentation using FRAGSTATS. Lastly, we identified potential connectivity corridors and constructed a potential protection network based on the least-cost path and the circuit theory. The results showed concentrations of M. moschiferus in the northern Greater Khingan Mountains, the southeastern Lesser Khingan Mountains, and the eastern Changbai Mountains, with a potential distribution area of 127,442.14 km2. Conservation priority areas included 41 core patches with an area of 106,306.43 km2. Patch fragmentation mainly occurred in the Changbai Mountains and the Lesser Khingan Mountains. We constructed an ecological network composed of 41 core patches and 69 linkages for M. moschiferus in Northeast China. The results suggest that the Greater Khingan Mountains represent the most suitable area to maintain the stability of M. moschiferus populations in Northeast China. Considering the high habitat quality requirements of M. moschiferus and its endangered status, we propose that the Chinese government accelerates the construction of the Greater Khingan Mountains National Park and the Lesser Khingan Mountains National Park and enlarges the Northeast China Tiger and Leopard National Park to address the fragmentation of protected areas and the habitat of M. moschiferus.

Southeast Asian protected areas are effective in conserving forest cover and forest carbon stocks compared to unprotected areas

Protected areas aim to conserve nature, ecosystem services, and cultural values; however, they have variable success in doing so under high development pressure. Southeast Asian protected areas faced the highest level of human pressure at the turn of the twenty-first century. To estimate their effectiveness in conserving forest cover and forest carbon stocks for 2000–2018, we used statistical matching methods to control for the non-random location of protected areas, to compare protection against a matched counterfactual. We found Southeast Asian protected areas had three times less forest cover loss than similar landscapes without protection. Protected areas that had completed management reporting using the Management Effectiveness Tracking Tool (METT) conserved significantly more forest cover and forest carbon stocks than those that had not. Management scores were positively associated with the level of carbon emissions avoided, but not the level of forest cover loss avoided. Our study is the first to find that METT scores could predict the level of carbon emissions avoided in protected areas. Given that only 11% of protected areas in Southeast Asia had completed METT surveys, our results illustrate the need to scale-up protected area management effectiveness reporting programs to improve their effectiveness for conserving forests, and for storing and sequestering carbon.

Assessing Protected Area Management Effectiveness: the Need for a Wetland-Specific Evaluation Tool

The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat was developed in 1971, and has established the world's largest network of protected areas. However, monitoring and reporting have been inadequate to fully achieve the goals of the Convention. We argue that current reporting mechanisms, including the Management Effectiveness Tracking Tool (METT), Rapid Assessment and Prioritization of Protected Area Management (RAPPAM), and the R-METT reporting framework adopted at the 12th Conference of the Parties, are not well adapted to wetland systems and the objectives of the Ramsar Convention. This paper outlines one possible structure for a new reporting mechanism, explicitly focused on the Convention's objectives of maintaining ecological character and promoting wise use within the context of sustainable development. Through these lenses, we developed a 15-question framework that would have site managers compile the most pertinent information relating to these two points quickly, including providing operational definitions, identifying allowable uses, quantifying economic benefits, reporting fundamental monitoring data, and assessing stakeholder engagement opportunities. We argue that, if we are to provide an informed outlook for the next half-century of wetland conservation under the Ramsar Convention, we must begin by refining its information-gathering protocols for its system of wetlands of international importance.

An Outcome-Oriented, Social–Ecological Framework for Assessing Protected Area Effectiveness

Both the number and the extent of protected areas have grown considerably in recent years, but evaluations of their effectiveness remain partial and are hard to compare across cases. To overcome this situation, first, we suggest reserving the term effectiveness solely for assessing protected area outcomes, to clearly distinguish this from management assessments (e.g., sound planning). Second, we propose a multidimensional conceptual framework, rooted in social–ecological theory, to assess effectiveness along three complementary dimensions: ecological outcomes (e.g., biodiversity), social outcomes (e.g., well-being), and social–ecological interactions (e.g., reduced human pressures). Effectiveness indicators can subsequently be evaluated against contextual and management elements (e.g., design and planning) to shed light on management performance (e.g., cost-effectiveness). We summarize steps to operationalize our framework to foster more holistic effectiveness assessments while improving comparability across protected areas. All of this can ensure that protected areas make real contributions toward conservation and sustainability goals.

Development evaluation of nature reserves under China’s forestry department: A spatiotemporal empirical study at the province level

It is important to evaluate the development level of nature reserves. In this study, we aimed to assess the development level of nature reserves under the administration of China’s forestry department in 31 provincial-level regions from 2005 to 2017 (excluding Hong Kong Special Administrative Region, Macao Special Administrative Region, and Taiwan Province). For this purpose, we analyzed the spatial and temporal evolution of nature reserve development in different regions using projection pursuit and spatial econometric methods. In terms of temporal distribution, the development level of nature reserves has been steadily improving, and the growth rate showed the trend of “strong fast” and “weak slow”. However, the development gap among different provinces is large. In terms of spatial distribution, the development of nature reserves presented the characteristics of “high in the west and low in the east” and “high in the north and south and low in the middle.” The endowment of natural resources, scientific research, and investment has a considerable effect on the development level of nature reserves. This study provides suggestions for the differential construction and sustainable development of nature reserves in China.

The mismeasure of conservation

One of the basic purposes of protected areas and other effective area-based conservation interventions is to achieve conservation impact, the sum of avoided biodiversity loss and promoted recovery relative to outcomes without protection. In the context of the Convention on Biological Diversity's negotiations on the post-2020 Global Biodiversity Framework, we find that targets for area-based interventions are framed overwhelmingly with measures that fail to inform decision-makers about impact and that risk diverting limited resources away from achieving it. We show that predicting impact in space and time is feasible and can provide the basis for global guidance for jurisdictions to develop targets for conservation impact and shift investment priorities to areas where impact can be most effectively achieved.

Characterisation of Vegetation Response to Climate Change: A Review

Climate change extreme events have consequential impacts that influence the responses of vegetation dynamics as well as ecosystem functioning and sustainable human well-being. Therefore, vegetation response to climate change (VRCC) needs to be explored to foster specific-organised management programmes towards ecological conservation and targeted restoration policy to various climate extreme threats. This review aimed to explore the existing literature to characterise VRCC and to identify solutions and techniques fundamental in designing strategies for targeted effective adaptation and mitigation to achieve sustainable planning outcomes. Accordingly, this review emphasised recent theoretical and practical research on the vegetation-climate responses and their related impacts in the wake of climate change and its debilitating impacts on vegetation. Consequently, this study proposes the Information-based model (IBM), needed to examine Factors–forms of Impacts–Solutions (Techniques)–Risks assessment to identify and provide insights about VRCC in a given region. In conclusion, two enablers of adaptive indicators and the novel systems-based serve as a key policy formulation for sustainability in strengthening the goals of global involvement of local and sub-national governments and institutions in the effective management of vegetation and ecosystem protection.

Which management measures lead to better performance of China's protected areas in reducing forest loss?

Protected areas (PAs) are considered essential for biodiversity conservation, and concerns about the effectiveness of PAs in terms of reducing deforestation are growing. However, few studies have identified the management measures that best reduce deforestation within existing PAs. Here, we carried out 10-year (from 2007 to 2016) field surveys and obtained a database of 10 management measures of 227 PAs mainly protecting forest ecosystems in China. We examined the contributions of the above 10 management measures in relation to the effectiveness of 227 PAs in reducing deforestation. Our results indicated that 52.68% of PAs had positive effects related to reducing deforestation (E > 0, P < 0.05), while 16.52% of PAs had negative effects (E < 0, P < 0.05). The most important management measures affecting the effectiveness of PAs in reducing deforestation were funding, infrastructure, and scientific research and monitoring. Thus, our study provides evidence indicating that improved funding and scientific research benefit the effectiveness of PAs. The findings have global implications for guiding PAs to take explicit measures to improve the outcomes of biodiversity conservation.

The Effectiveness of Protected Areas in Conserving Globally Threatened Western Tragopan Tragopan melanocephalus

Simple Summary

Western Tragopan is a globally threatened pheasant species of the Western Himalayan Biodiversity Hotspot, whereas protected areas are tools used to protect species and their habitat. In this study, we selected protected areas falling within the potential habitat of the Western Tragopan and evaluated their management effectiveness to understand their role in the protection of the pheasants of global conservation concern. Our results show that only Machiara National Park scored just above 40% (indicating relatively weak management), 22 of the PAs fell within the 25–50% quantile (indicating weak management), and 3 scored below 25% (indicating poor management). PAs within the species distributional range covered 92,387 ha which is only 2% of the total potential habitat of the tragopan. Thus, we concluded that protected areas are not sufficiently contributing to protecting species and its habitat and need to revise their plans. We further recommended establishment of more protected areas within the potential habitat of the species to help protect this iconic species of Western Himalaya.

Abstract

Protected areas are a critical tool to conserve biodiversity in the face of the global crisis of species extinction. Here, we present the first ever management effectiveness assessment of Pakistan’s Protected Areas (PAs). We link these assessments to the delivery of conservation outcomes focusing on the threatened Western Tragopan (Tragopan melanocephalus) endemic to Pakistan and India. We used two approaches, first mapping the spatial distribution of potential habitat coverage using machine learning ensemble models and second, an assessment of the management effectiveness of protected areas. Our results show that only Machiara National Park scored just above 40% (indicating relatively weak management), 22 of the PAs fell within the 25–50% quantile (indicating weak management), and 3 scored below 25% (indicating poor management). PAs within the species distributional range covered 92,387 ha which is only 2% of the total potential habitat of the Tragopan. Scoring of Planning element was insufficient both in term of the site and species. Likewise, inputs (e.g., research and monitoring program, staff numbers, staff training, current budget, security of budget, and management after process) were also inadequate. Finally, we recommend the establishment of more protected areas within the species potential habitat and inclusion of species-specific plans in Pakistan’s PAs management.

To Trade or Not to Trade? Using Bayesian Belief Networks to Assess How to Manage Commercial Wildlife Trade in a Complex World

International commercial trade in wildlife, whether legal or illegal, is one of the greatest threats to multiple species of wildlife today. Opinions on how to address it are deeply divided across the conservation community. Approaches fall into two broad categories: making the trade illegal to protect against any form of commercial trade or allowing some or all of the trade to be legal and seeking to manage it through sustainable trade. The conservation community is often deeply polarized on which is the better option. We posit that a way to choose between these options is by considering species-specific attributes of biological productivity, management context, and demand. We develop a conceptual framework to assess which option is more likely to result in successful conservation of a species. We show how to construct a Bayesian Belief Network (BBN) to model how these attributes (1) interact to affect the sustainability of the species’ population and (2) vary under different trade management regimes. This approach can support scientifically based decision-making, by predicting the likely sustainability outcome for a population of a species under different trade management regimes, given its particular characteristics and context. The BBN allows identification of key points at which conservation interventions could change the potential outcome. It also provides the opportunity to explore how different assumptions about how humans might respond to different trade regimes affects outcomes. We illustrate these ideas by using the BBN for a hypothetical terrestrial mammal species population and discuss how the BBN can be extended for species with different characteristics, for example, those that can be stockpiled or when there are multiple products. This approach has the potential to help the conservation community to assess the most appropriate regime for managing wildlife trade in a transparent, open, and scientifically based way.

Changes in the human footprint in and around Indonesia's terrestrial national parks between 2012 and 2017

The human footprint (HF) was developed to measure of the impact of human activities on the environment. The human footprint has been found to be closely related to the vulnerability of protected areas around the world. In Indonesia, as nature conservation is still seen as hindering economic development, it is especially important to assess the human footprint in order to comprehend the overall pressures resulting from the various human activities on Indonesia's national parks. This study measured the change in the human footprint in and around 43 terrestrial national parks over 5 years, between 2012 and 2017. As many as 37 out of 43 NPs experienced an increase in the HF, ranging from 0.4 to 77.3%. Tanjung Puting in Kalimantan experienced the greatest increase (77.3%), while Ujung Kulon in Jawa Bali bioregion had the greatest decrease (10.5%). An increase in human population density and improved access to parks from roads, rivers and coastlines are the main drivers of increasing impacts on national parks.

Durable Freshwater Protection: A Framework for Establishing and Maintaining Long-Term Protection for Freshwater Ecosystems and the Values They Sustain

Long-term protection is needed to secure threatened freshwater ecosystems and the social and biodiversity values they provide. In the face of existing and future pressures, current approaches to freshwater protection are often inadequate for maintaining ecosystem values into the future. While terrestrial and marine ecosystem protection are well recognized and have area-based protection goals in global conventions, freshwater ecosystem characteristics have remained poorly represented in these goals. Freshwater ecosystems are commonly secondary or unaddressed components of area-based terrestrial protection. The design and management for terrestrial-based protection are generally inadequate for addressing freshwater ecosystem processes and attributes critical for maintaining their natural patterns and the values they provide to people and nature. Given that freshwater-dependent species are declining at a faster rate than marine and terrestrial species, and the reliance and use of freshwater ecosystems by people living around such areas, approaches to protect them must balance the needs of people and nature and accommodate these complexities.

Area-based conservation in the twenty-first century

Humanity will soon define a new era for nature-one that seeks to transform decades of underwhelming responses to the global biodiversity crisis. Area-based conservation efforts, which include both protected areas and other effective area-based conservation measures, are likely to extend and diversify. However, persistent shortfalls in ecological representation and management effectiveness diminish the potential role of area-based conservation in stemming biodiversity loss. Here we show how the expansion of protected areas by national governments since 2010 has had limited success in increasing the coverage across different elements of biodiversity (ecoregions, 12,056 threatened species, 'Key Biodiversity Areas' and wilderness areas) and ecosystem services (productive fisheries, and carbon services on land and sea). To be more successful after 2020, area-based conservation must contribute more effectively to meeting global biodiversity goals-ranging from preventing extinctions to retaining the most-intact ecosystems-and must better collaborate with the many Indigenous peoples, community groups and private initiatives that are central to the successful conservation of biodiversity. The long-term success of area-based conservation requires parties to the Convention on Biological Diversity to secure adequate financing, plan for climate change and make biodiversity conservation a far stronger part of land, water and sea management policies.

Remote Sensing Applications for Monitoring Terrestrial Protected Areas: Progress in the Last Decade

Terrestrial protected areas (PAs) play an essential role in maintaining biodiversity and ecological processes worldwide, and the monitoring of PAs is a useful tool in assessing the effectiveness of PA management. Advanced remote sensing technologies have been increasingly used for mapping and monitoring the dynamics of PAs. We review the advances in remote sensing-based approaches for monitoring terrestrial PAs in the last decade and identify four types of studies in this field: land use & land cover and vegetation community classification, vegetation structure quantification, natural disturbance monitoring, and land use & land cover and vegetation dynamic analysis. We systematically discuss the satellite data and methods used for monitoring PAs for the four research objectives. Moreover, we summarize the approaches used in the different types of studies. The following suggestions are provided for future studies: (1) development of remote sensing frameworks for local PA monitoring worldwide; (2) comprehensive utilization of multisource remote sensing data; (3) improving methods to investigate the details of PA dynamics; (4) discovering the driving forces and providing measures for PA management. Overall, the integration of remote sensing data and advanced processing methods can support PA management and decision-making procedures.

Assessing the effectiveness of a national protected area network for carnivore conservation

Protected areas (PAs) are essential to prevent further biodiversity loss yet their effectiveness varies largely with governance and external threats. Although methodological advances have permitted assessments of PA effectiveness in mitigating deforestation, we still lack similar studies for the impact of PAs on wildlife populations. Here we use an innovative combination of matching methods and hurdle-mixed models with a large-scale and long-term dataset for Finland's large carnivore species. We show that the national PA network does not support higher densities than non-protected habitat for 3 of the 4 species investigated. For some species, PA effects interact with region or time, i.e., wolverine densities decreased inside PAs over the study period and lynx densities increased inside eastern PAs. We support the application of matching methods in combination of additional analytical frameworks for deeper understanding of conservation impacts on wildlife populations. These methodological advances are crucial for preparing ambitious PA targets post-2020.

Quantification of Soil Losses along the Coastal Protected Areas in Kenya

Monitoring of improper soil erosion empowered by water is constantly adding more risk to the natural resource mitigation scenarios, especially in developing countries. The demographical pattern and the rate of growth, in addition to the impairments of the rainfall pattern, are consequently disposed to adverse environmental disturbances. The current research goal is to evaluate soil erosion triggered by water in the coastal area of Kenya on the district level, and also in protected areas. The Revised Universal Soil Loss Equation (RUSLE) model was exercised to estimate the soil loss in the designated study area. RUSLE input parameters were functionally realized in terms of rainfall and runoff erosivity factor (R), soil erodibility factor (K), slope length and gradient factor (LS), land cover management factor (C) and slope factor (P). The realization of RUSLE input parameters was carried out using different dataset sources, including meteorological data, soil/geology maps, the Digital Elevation Model (DEM) and processing of satellite imagery. Out of 26 districts in coastal area, eight districts were projected to have mean annual soil loss rates of >10 t·ha−1·y−1: Kololenli (19.709 t·ha−1·y−1), Kubo (14.36 t·ha−1·y−1), Matuga (19.32 t·ha−1·y−1), Changamwe (26.7 t·ha−1·y−1), Kisauni (16.23 t·ha−1·y−1), Likoni (27.9 t·ha−1·y−1), Mwatate (15.9 t·ha−1·y−1) and Wundanyi (26.51 t·ha−1·y−1). Out of 34 protected areas at the coastal areas, only four were projected to have high soil loss estimation rates >10 t·ha−1·y−1: Taita Hills (11.12 t·ha−1·y−1), Gonja (18.52 t·ha−1·y−1), Mailuganji (13.75.74 t·ha−1·y−1), and Shimba Hills (15.06 t·ha−1·y−1). In order to mitigate soil erosion in Kenya’s coastal areas, it is crucial to regulate the anthropogenic disturbances embedded mainly in deforestation of the timberlands, in addition to the natural deforestation process caused by the wildfires.

A global-level assessment of the effectiveness of protected areas at resisting anthropogenic pressures

One-sixth of the global terrestrial surface now falls within protected areas (PAs), making it essential to understand how far they mitigate the increasing pressures on nature which characterize the Anthropocene. In by far the largest analysis of this question to date and not restricted to forested PAs, we compiled data from 12,315 PAs across 152 countries to investigate their ability to reduce human pressure and how this varies with socioeconomic and management circumstances. While many PAs show positive outcomes, strikingly we find that compared with matched unprotected areas, PAs have on average not reduced a compound index of pressure change over the past 15 y. Moreover, in tropical regions average pressure change from cropland conversion has increased inside PAs even more than in matched unprotected areas. However, our results also confirm previous studies restricted to forest PAs, where pressures are increasing, but less than in counterfactual areas. Our results also show that countries with high national-level development scores have experienced lower rates of pressure increase over the past 15 y within their PAs compared with a matched outside area. Our results caution against the rapid establishment of new PAs without simultaneously addressing the conditions needed to enable their success.
