Monday, October 18th, 2010The Missouri River Watershed Coalition (MRWC) launched an Early Detection and Distribution Mapping System (EDDMapS) on September 28, 2010.  This system will provide a means of reporting new sightings of select invasive species, a mechanism to alert appropriate individuals to the reports and generate distribution maps for reported species. The MRWC EDDMapS will focus on species that are new or potentially new invaders to the Coalition states and these reports will form the database rather than historical or current distribution data for all invasive species within the six states.
