Effectiveness of forestry BMPs for roads

In 2011, NCASI initiated a review of available technical information about the effectiveness of forestry best management practices (BMPs) for roads. The review was conducted by Drs. George Ice and Erik Schilling. Their report was published recently as NCASI Special Report No. 12-01, Assessing the Effectiveness of Contemporary Forestry Best Management Practices (BMPs): Focus on Roads.

Critical habitat for northern spotted owl

The U.S. Fish and Wildlife Service has released its proposal to revise designated critical habitat for the northern spotted owl under the Endangered Species Act. The proposal identifies for public comment 13,962,449 acres in California, Oregon, and Washington that meet the definition of critical habitat. Identified areas include more than 1.2 million acres of private forest land. NCASI is reviewing the critical habitat proposal and draft Environmental Impact Statement for barred owl removal with emphasis on statistical methods and models used by the Service to define critical habitat.

Effects of spatial scale on forest carbon accounting

C.S. Galik and R.C. Abt are the authors of an important new report titled The Effect of Assessment Scale and Metric Selection on the Greenhouse Gas Benefits of Woody Biomass. The report demonstrates that spatial scale of analysis can have major effects on models of the “carbon footprint” of biomass energy systems. For example, results of plot-level analyses in this study were inconsistent with results of analyses at larger spatial scales.

Conservation and management of eastern big-eared bats

Big-eared bats (genus Corynorhinus) in the eastern United States are often associated with hardwood forest habitats and are potentially at risk due to factors such as habitat loss, disturbance to hibernacula and maternity sites, contaminants, genetic isolation, and disease. As a result, big-eared bats in the eastern US are species of special conservation concern. Biologists have expressed concern that more knowledge is needed before effective management of these species is possible. A symposium was held in March 2010 to discuss research findings and future directions in research and conservation. The proceedings have been published by the Forest Service as Conservation and Management of Eastern Big-eared Bats: A Symposium.
