Priority Species 

There are currently nine priority invasive species in Big Horn County that are the main focus for the 100% cost-share program offered by Big Horn County Weed and Pest District.  The cost of controlling these priority species on Private Lands, including labor and herbicides, is covered by the District.  Most of these weeds are well controlled with herbicides, however, finding and identifying individual plants on a landscape scale can be difficult.  The majority of the cost in controlling priority species is labor, this demonstrates the importance of EDRR (Early Detection/Rapid Response) practices.
