Streamkeepers' Noxious Weed Data and Habitat-Quality Scores, 1999 to 2005
Streamkeepers collects data on invasive exotic weeds, in coordination with the Clallam County Noxious Weed Control Board. From 1999 to 2005, Streamkeepers conducted extensive monitoring of stream habitat, including noxious weeds.
Streamkeepers has collated all of our noxious weed data from that time period from our physical-habitat monitoring sites and then calculated noxious weed grades for those sites from the point of view of noxious weed-based habitat degradation. The grades are based on a scoring table that Streamkeepers created for this purpose.
We have done a preliminary study of the strength of correlation between noxious weed grades and other measures of watershed health, such as biological integrity and land use/land cover.
This is part of a larger effort to create a Physical Habitat Index which assigns habitat-quality scores to sites where Streamkeepers collected physical-habitat data from 1999-2005.
