Western Wildlife

The Forest Industry’s Western Wildlife Program (WWP) is documenting wildlife habitat support and biodiversity in managed forests of the Pacific Northwest. WWP research results provide a scientific foundation for industry efforts to advance cost-effective approaches to conserving wildlife and biodiversity in managed forests.

The WWP is managed by the National Council for Air and Stream Improvement (NCASI) on behalf of four industry associations that provide core funding support (American Forest Resources Council, Oregon Forest Industries Council, Washington Forest Protection Association, and NCASI). Program oversight and guidance are provided by industry representatives serving on the technical Western Wildlife Task Group and the strategic Program Steering Committee.

Activities of the WWP are managed by NCASI Program Manager Dr. Jake Verschuyl and directed by sponsoring organizations (AFRC, OFIC, WFPA and NCASI) working through a Program Steering Committee (PSC) and Western Wildlife Task Group (WWTG). The PSC comprises representatives of AFRC, OFIC and WFPA. Important functions of the PSC include (a) ensuring that WWP activities are properly aligned with strategic priorities of AFRC, OFIC and WFPA; and (b) coordinating efforts to obtain core regional funding support for the WWP. The WWTG comprises industry wildlife biologists and other technical experts who (a) provide detailed technical guidance and oversight to NCASI staff, and (b) provide program / budget recommendations to the PSC and NCASI’s Forest Environment and Sustainability Task Group
