Typology of Ohio, USA, tree farmers based upon forestry outreach needs

This study differentiated groups of Ohio tree farmers through multivariate clustering of their perceived needs for forest management outreach. Tree farmers were surveyed via a mailed questionnaire. Respondents were asked to rate, on a 1-7 scale, their informational needs for 26 outreach topics, which were reduced to six factors. Based on these factors, three clusters were identified-holistic managers, environmental stewards, and pragmatic tree farmers. Cluster assignment of individuals was dependent upon a tree farmer's age, acreage owned, and number of years enrolled in the American Tree Farm System. Holistic managers showed a greater interest in the outreach topics while pragmatic tree farmers displayed an overall lesser interest. Across clusters, print media and in-person workshops were preferred over emails and webinars for receiving forest management information. In-person workshops should be no more than 1 day events, held on a weekday, during the daytime, at a cost not exceeding $35. Programming related to environmental influences, which included managing for forest insects and diseases, was concluded to have the greater potential to impact clientele among all outreach factors due to the information being applicable across demographics and/or management objectives.

Preference of Formosan subterranean termites for blue-stained southern yellow pine sapwood

Little research has been conducted to investigate interactions between the invasive Formosan subterranean termite, Coptotermes formosanus Shiraki, and pine bark beetles native to the southeastern United States. Facilitative interactions between these organisms could alter stand dynamics and impact wood utilization strategies. American Wood Protection Association Standard E1-09 choice tests were carried out to determine the feeding preference of Formosan subterranean termites for blue-stained versus unstained southern yellow pine sapwood. Three separate colonies of Formosan subterranean termites consumed on average twice as much air-dried blue-stained southern yellow pine sapwood over unstained air-dried controls. Additionally, Formosan subterranean termites consumed over five-times more kiln-dried blue-stained sapwood than unstained kiln-dried control wafers. The implications of these results are particularly relevant to pine forest ecology, nutrient cycling, and the utilization of blue-stained southern pine building products in the southeastern United States, where Formosan subterranean termites have become established.
