Seminar Series - USGS EcoLunch
Date: Tuesday, October 28th
Time: 12:00 pm MDT
Speaker(s): Siri Wilmoth, USGS Statistician
Title: Establishing reference conditions for wadeable rivers and streams in Washington State.
Abstract: The first step of any watershed assessment is establishing criteria for least disturbed condition. We use an existing set of 75 Best Professional Judgment (BPJ) reference sites and 351 random sites to characterize reference conditions for wadeable rivers and streams in Washington State. Our general approach was to determine which set of environmental variables were most sensitive to the differences between reference and random sites within a region, and to utilize these variables in multivariate clustering and ordination techniques. We propose statistical criteria for establishing reference conditions from the results of these multivariate clustering and ordination techniques. Then, we utilize these statistical criteria to determine whether any of the probability sites meet the expectations for reference condition; or, alternatively, whether any of the established BPJ reference sites do not meet the expectations.
