Annual monitoring of US timber production

The Forest Inventory and Analysis (FIA) program of the US Forest Service (USFS) includes a survey-based data collection and reporting effort known as Timber Products Output (TPO). The TPO program surveys wood-using manufacturing facilities to estimate production of roundwood from forests by county. This information, in conjunction with inventory plots measured in forests, is crucial for monitoring forest growth and harvest, evaluating the impact of emerging markets, and assessing the sustainability of wood utilization in the US.

Draft Habitat Conservation Plan for bat species

Populations of some forest bat species have been rapidly declining due to white-nose syndrome, a fungal disease. As a result, the U.S. Fish & Wildlife Service recently listed the northern long-eared bat as threatened under the Endangered Species Act (ESA). The tri-colored bat is currently undergoing a status review, and several other bat species may eventually undergo ESA listing determinations. Over the last several years, the Departments of Natural Resources in Michigan, Minnesota, and Wisconsin have been collaborating to develop a large-scale Habitat Conservation Plan known as the Lake State Forest Management Bat Habitat Conservation Plan (HCP).

U.S. Forest Service releases final Northwest Forest Plan science synthesis

The U.S. Forest Service’s Pacific Northwest and Pacific Southwest Research Stations have electronically published a Northwest Forest Plan (NWFP) science synthesis in the form of an agency General Technical Report. The synthesis, which was prepared by scientists with the Forest Service, other federal agencies, universities, and tribes, is a review of the science that has emerged since the plan was enacted in 1994 and is intended to provide a science foundation for forest plan revisions for 17 national forests within the 24-million-acre NWFP area in western Washington, western Oregon, and northern California.

Stream temperature effects from contemporary forest harvesting

Forest management activities, such as harvesting near streams, have the potential to increase summertime stream temperatures if they reduce shade and increase sunlight reaching the stream surface. Recently, investigators associated with Oregon State University, Otak, Inc., University of Northern Colorado, and Weyerhaeuser Company published a paper in the journal Hydrological Processes that evaluates the downstream stream temperature responses to forest harvesting by integrating data from three paired watershed studies (Trask, Hinkle, and Alsea) in headwater streams of western Oregon. NCASI contributed to support of these studies and development of the publication.
