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 …
Forest Succession And Amphibian Migrations: Implications For Landscape Connectivity, Viorel Dan Popescu
Forest Succession And Amphibian Migrations: Implications For Landscape Connectivity, Viorel Dan Popescu
Electronic Theses and Dissertations
Conservation of forest-dependent amphibians is dependent on finding a balance between timber management and species’ habitat requirements. Accurate predictions of the response of amphibian communities to disturbance rely on a good understanding of the scales at which ecological processes affect distribution and abundance through space and time. I investigated the response of 14 species to four different forestry treatments (partial harvest, clearcut with coarse woody debris [CWD] removed, clearcut with CWD retained, and uncut control) over a six-year period, using 2.1-ha experimental treatments. Forest amphibians showed a strong negative response to complete canopy removal at a broad spatial scale, but …
