PNW Project Overview 2001

The Response of Coarse Woody Debris (CWD) Invertebrates to Alternative Silvicultural Practices

Principal Investigators:  
Dr. Robert Edmonds, University of Washington, College of Forest Resources
Dr. Jim Marra, University of Washington, College of Forest Resources

Awarded: $7,000

Project Description:
This study samples early Habitat Development Study installations of variable density thinning in the Soleduck ranger district, comparing CWD invertebrates in thinned versus unthinned plots. In addition, the project compares CWD invertebrates in clumped versus dispersed CWD treatments at a site in the Hood Canal ranger district. Results of this study will be used to evaluate alternative methods of harvesting that attempt to combine timer harvesting with the creation of late successional wildlife habitat.  Supplemental funding in 2001 will be used for the identification of coarse woody debris arthropods as part of the proposed study investigating coarse woody debris arthropod response to variable density thinning and bundling of small diameter coarse woody debris.

Project Status:
2001 funds will be distributed to projects in September 2001.  In cooperation with Dr. Andrew Moldenke, Entomology Department Oregon State University, remaining identification will be completed during the winter of 2001-2002.  The remainder of 2002 will be devoted to data analysis and write up of a final manuscript to be submitted for publication.
