Publication Summary

This report summarizes progress to date on the pilot phase of the sediment best management practices (BMPs) effectiveness study sponsored by the Timber/Fish/Wildlife Cooperative Monitoring, Evaluation and Research Committee. As of October 1992, the project team had established 12 study sites for evaluating 27 examples of BMP implementation in four physiographic regions of the state. These examples include BMPs for timber harvesting using tractor/wheeled skidding systems, new road construction, and haul road maintenance.

Study site selection criteria are discussed, and field survey methods are summarized. The report also includes a preliminary assessment of sampling design for the study, and presents a slightly revised sample stratification scheme. In the revised scheme, the Puget Lowlands, Columbia basin, and Blue Mountains physiographic regions are excluded from the sample, leaving study sites to be distributed among the Olympic Peninsula, Willapa Hills, Southern Cascades, Northern Cascades, Eastern Cascades, and Northern Rockies physiographic regions.
