Demo Sites

With the help of the Crook County Weed Supervisor and The Crooked River Weed Management Area (CRWMA) demonstration weed control sites was established on primarily county, city or park properties to educate the Forest Service and the public as to proper weed management. These field trials assisted the Ochoco National Forest to better utilize the new expanded chemical products list in their EIS. The site were over a period of 5 years on approximately 15 demonstration sites. Priority noxious weed species such as medusahead rye, Scotch thistle, spotted and diffuse knapweed, hounds tongue and yellow starthistle plots were established. The Weed Supervisor applied the initial chemical control at different rates and applied subsequent treatments if needed. CRWMA monitor demo sites from 2010 to 2015.

Aquatic Invasive

Crooked River Weed Management Area personnel (CRWMA) surveyed aquatic plants in over 75 locations in Crook, Jefferson and Deschutes Counties in order to early detect invasive species and to establish a baseline for aquatic plant species, both native and introduced, in our aquatic habitats. From September through mid-October 2011, 76 aquatic habitats including ponds, creeks, rivers, lakes and reservoirs in Deschutes, Jefferson and Crook Counties were sampled. Over forty aquatic plant species were identified. Only two were non-native; Eurasian water-milfoil and curly leaf pondweed.
