Database is a comprehensive database of exotic plant names and weed
distribution records for five states in the northwestern United
States. The spatial and temporal spread of weeds can be displayed
using the historic distribution records in INVADERS. The INVADERS
web site contains actual examples of how land management and weed
regulatory agencies are using these data to improve their weed
management programs. Noxious weed listings are provided for all
US states and six southern tier Canadian provinces.
database structures and web-based query interface are a generalized
software design that can be adapted to cover other regions and/or
provide a national/continental scale system for early detection,
tracking, and strategic management of invasive species. Weed
managers interested in cooperating in the geographic expansion of
the INVADERS system should contact Peter Rice, the Project Director.
