DESCRIPTION
Riparian weeds degrade salmon habitat by displacing native species, disrupting native succession patterns, reducing shade by outcompeting taller species, increasing sedimentation and clogging small streams and side channels. Currently, all SRFB/PSAR restoration projects, and many acquisitions, include treatment of invasives on protected parcels, as well re-vegetation efforts. However, other than those projects either owned and/or managed by watershed partners, there has been little success tracking species along river corridors in areas of private ownership. Additionally, there has been little effort to compile the data collected by individual agencies in the Nisqually Watershed. In addition to developing control and monitoring plans for prevalent watershed species, there is an effort to complete an updated riparian vegetation assessment that will allow for changes in riparian vegetation to be tracked over time, taking advantage of new sources of data. Expanding the assessment to include the entire channel migration zone of the mainstem will include areas that may be activated during climate change induced flooding. Data will be collected via GIS amongst partners that have entered into a memorandum of understanding for the Nisqually River Cooperative Weed Management Area.
