Early Detection

The foundation of a successful invasive species control program is the development and maintenance of a current, detailed inventory of target species distribution.   Click for State District Storybooks

FCWP Survey MapIn addition to State Designated and County Declared Noxious Weeds and Pests, there are dozens of weeds of concern and watch list weeds in nearby states and counties that are of interest to Fremont County. Knowledge of their presence and population densities is essential in developing effective control programs and efficient use of resources.  ​

FCWP staffs a systematic invasive plant  survey with the goal of examining all weed susceptible lands in the county at least every five years. About 20 percent of the land surface is surveyed each year. When possible, FCWP seeks funding from public land agencies to help cover the cost of surveying the lands they manage. With landowner permission, private lands are surveyed at no cost to the owners and, upon request, a Weed Management Plan is made available to each property owner.

Rapid Response

GIS mappers and EDRR treatment crews work together to locate new invaders and eradicate them before they become large and more expensive to control. An EDRR treatment crew, typically one or two people, can be thought of as a small strike force that is light and mobile for wiping out small, high priority infestations. Monitoring past treatment sites is an important aspect of EDRR. Crews evaluate the effectiveness of treatments and re-treat infestations that require follow-up work. Over the long term, the costs of weed control can be lowered by gathering and maintaining current GIS data and responding quickly to eradicate new infestations
