The Purgatoire Watershed Weed Management Collaborative (PWWMC) arose from a common commitment to a truly stunning and ecologically remarkable watershed. The Purgatoire River, and surrounding landscape, represents one of the most ecologically intact watersheds in the state of Colorado. In 2004, out of growing concern for the impact of noxious weeds on this unique environment, the PWWMC partnership was formed. One of the first major projects was compiling a preliminary assessment of two major noxious tree species, tamarisk and Russian-olive.
After a decade of hard work, PWWMC was formalized in January of 2016 among RiversEdge West, Spanish Peaks-Purgatoire River Conservation District and Purgatoire Watershed Partnership. PWWMC is now the Spanish Peaks-Purgatoire River Conservation District’s designated noxious weed program.
PWWMC has grown and flourished, treating nearly 2,000 acres of noxious weeds within the watershed and working with over 50 landowners. Such success can be attributed to the extensive ongoing support from local landowners, conservation agencies, governmental entities and businesses.
