Noxious and Invasive Weeds in or near the Battle Creek Watershed

Exotic or non-native plants pose a threat to the entire Battle Creek ecosystem, including fish and wildlife populations, and represent a danger to the continued use of ranchlands for grazing. The invasion of exotic weeds, altering the biodiversity of plants for forage could forever alter the use of the land.

Battle Creek Watershed Conservancy Weed Management Report
In September 2001 The Tehama County Resource Conservation District (TCRCD) conducted a noxious weed inventory at the request of the Battle Creek Watershed Conservancy. The inventory was done on the Lazy R Bahr Ranch with the cooperation of the landowner. The results of the inventory will aid the landowner in establishing goals for weed management that suit the needs of the ranch. By establishing weed management goals, a landowner can take a proactive approach in preventing, confining or eradicating noxious weeds on their property.
