RRNW Speaker Series January 12th: Rick Hafele
This program will provide a historical perspective of watershed and stream conditions in the Willamette River Basin starting with the arrival of EuroAmericans in the region in the early to mid 1800s. Monitoring and restoration programs often use reference or least disturbed sites to describe natural conditions. But how different are todays reference sites from the conditions that existed prior to the large scale changes that have taken place since EuroAmericans populated the region? While returning to pre-European conditions is not possible, understanding the historical context and the type of changes that have occurred, might help todays monitoring programs better define reference condition and help restoration programs develop the best possible goals or targets for stream habitat and aquatic life.

Note: The information presented in this program was funded as part of a larger national EPA program called the Biological Condition Gradient (BCG). The BCG is intended to help states more precisely define and interpret baseline biological conditions, help evaluate improvement potential of degraded waters, and measure and document incremental changes in condition along a gradient of anthropogenic stress.

A BCG program in the Pacific Northwest began three years ago using macroinvertebrate data collected from streams across a wide range of stream conditions in the Willamette Valley and Puget Lowland ecoregions. More information about the BCG program can be found at:  https://www.epa.gov/sites/production/files/2016-02/documents/bcg-practioners-guide-report.pdf
