- Generate an "Alert List" of recently introduced
weeds that are spreading rapidly across the region. An
early warning list is an essential prerequisite for
- The Extension Service could determine which new weeds
need to be included in ID training programs and
bulletins, and where efforts for established weeds need
to be increased.
- Each county weed supervisor or other agency weed manager
could be provided with a county, approximate area,
district, or forest specific list of exotic plants and
sensitive native species.
- Program can detect where a weed came from by plotting
regional scale distribution patterns for sequential time
intervals. Crop inspection, vehicle cleaning, and other
regulatory actions could be used to reduce the transport
of noxious weed seeds to new areas.
- Graphic plots of the cumulative number of counties
reporting a weed over the year of the report combined
with maps of the reported distribution suggest what type
of regional scale strategic management might be most
appropriate for that weed.
- Spread pattern plots, maps, and summary statistics and
graphics derived from the database could be use to
illustrate the extent and severity of the invasion
process to lay decision makers who make budgetary and
- A shared database on weed distributions and spread rates
could reduce the political aspects of listing weeds as
- Distribution maps help identify possible multi-agency
cooperators for weed management projects.
- Taxonomic name questions are greatly simplified because
the INVADERS software links old names (synonyms) to the
currently accepted scientific name as well as the Weed
Science Society common name.
- Each specific weed name could be linked to an "IPM
Toolbox" which would provide a list of registered
herbicides, biological agents, and references for control
strategies using grazing, cultivation, and mechanical
