U.S. Forest Service Northern Conifer Experimental Forests: Historical Review And Examples Of Silvicultural Research Applications, Kate Berven
Electronic Theses and Dissertations
This study investigates U.S. Forest Service silvicultural research in the northern mixed-conifer forest of the Northeast. Chapter 1 is an overview of three closed experimental forests and is a cautionary tale regarding lost research opportunities. The Paul Smith, Finch-Pryun, and Gale River Experimental Forests (EFs) were established in the early to mid 1900s. Changing societal needs and research priorities led to redirected staffing and funding; all three were disestablished. Initial investments were lost and outcomes of the experiments not fully realized. This chapter highlights the importance of retaining and properly storing records. The Penobscot EF is an exemplary illustration of …

Conservation of forest amphibians is dependent on finding the right balance between management for timber production and meeting species' habitat requirements. For many pond-breeding amphibians, successful dispersal of the juvenile stage is essential for long-term population persistence. We investigated the influence of timber-harvesting practices on the movements of juvenile wood frogs (Lithobates sylvaticus). We used a chronosequence of stands produced by clear-cutting to evaluate how stand age affects habitat permeability to movements. We conducted experimental releases of juveniles in 2008 (n = 350) and 2009 (n = 528) in unidirectional runways in four treatments: mature forest, recent clearcut, …
