Effective conservation and management of small mammals require knowledge of the population dynamics of co-occurring species. We estimated the abundances, autocorrelations, and spatiotemporal associations of 4 small-mammal species from 2011–2016 using live-trapping mark-recapture methods on 9 sites across elevation and canopy openness gradients of a late-successional forest in the H. J. Andrews Experimental Forest, on the west slope of the Oregon Cascades. We also quantified species-specific spatial variation in adult sex ratios and body mass. We used Huggins closed capture models to...

I examined the implementation of a midstory herbicide treatment as the first phase in a two-phase shelterwood prescription in upland hardwood stands in Alabama, Tennessee, and Kentucky. The initial prescription for all three sites was similar: use herbicide to reduce the density of the midstory, allowing increased light to the established oak (Quercus spp.) reproduction. The goal was to increase understory light to at least 20 percent of full sun to promote oak seedling growth and recruitment over other species. Light was increased, but ephemeral and not to the 20-percent full sun goal....

This resource update is a brief look at some of the basic metrics that describe the status of and changes to forest resources in Tennessee. This information is based on field data collected using the USDA Forest Service Forest Inventory and Analysis (FIA) annualized sample design, and it is updated yearly.

The 2017 Oak Symposium was convened in Knoxville, TN, to share knowledge on state-of-the-art management and research to improve sustainability of the upland oak resource in the Eastern United States. The symposium featured 33 invited speakers, an audience discussion period, a field trip, and 21 offered posters. Speakers addressed topics including the history of silviculture, fire, and research; current status of the oak resource; emerging economic markets; forest health; silviculture for climate change; artificial regeneration; wildlife habitat management; approaches to secure natural...
