Exotic forest pests cost China and the United States billions of dollars each year. Current regulatory systems worldwide are over-whelmed with the increasing volume of international trade. Trade in nursery stock, wood products, pallets and dunnage have proven the most common means of transport for…

A common study design has been installed at 13 locations throughout the South to track the growth of loblolly pine (Pinus taeda L.) plantations established with 4 different competition control treatments: no control (only chopping-burning), woody control for 5 years, herbaceous control for 4 years…

Hardwood forests of the eastern United States are characterized by a complex mix of species associations that make it difficult to construct useful indicators of long-term sustainability, in terms of future forest composition and stocking levels. The Pennsylvania Regeneration Study examines…

Secondary plant succession and the accumulation of biomass and nutrients were documented at seven ruminant exclosures in Abies and Pseudotsuga forests variously disturbed by logging, burning, and grass seeding. Long-term (25 or more years) foraging by Rocky Mountain mule deer (Odocoileus…

The effects of harvest intensity (sawlog, SAW; whole tree, WTH; and complete tree, CTH) on biomass and soil carbon (C) were studied in four forested sites in the Southeastern United States: (mixed deciduous forests at Oak Ridge, TN and Coweeta, NC; Pinus taeda at Clemson, SC; and P. eliottii at…

Understanding habitat relationships; of forest dwelling bats has become a wildlife management priority during the past decade. We used radiotelemetry to examine the use of day roosts by fringed myotis (Myotis thysanodes) in a Douglas-fir (Pseudotsuga menziesii) forest in northern…

Benthic meiofauna were collected from the pools of minute (0 order) streams in the Ouachita National Forest, Arkansas during March 21-23, 1996 to see if benthic communities responded to forest harvest methods in a similar manner as plankton communities collected two years prior. The study streams…
