California Invasive Plant Council.
a new Web site for mapping invasive plant spread
and planning regional
generate a report
for their region that synthesizes information into
three types of strategic opportunities: surveillance,
eradication and containment. Land managers can use
these reports to prioritize their invasive plant
management, to coordinate at the landscape level
(county or larger) and to justify funding requests.
For some species, CalWeedMapper also provides maps
of suitable range that show where a plant might be
able to grow in the future. The system was developed
by the California
Invasive Plant Council and is designed
to stay current by allowing users to edit data.

Early Detection & Distribution
Mapping System (EDDMapS)
University of Georgia. Center for Invasive
Species and Ecosystem Health.
Provides distribution data at the State and County level and point locations.
See the section Who's Using It? for mapping distribution in
various areas of the country. Includes:
Detection & Distribution Mapping System
(EDDMapS) - Alaska
Provides distribution data and abundance of exotic and invasive plant species
Detection & Distribution Mapping System
(EDDMapS) - Mid-Atlantic Early Detection Network
MAEDN is a vast network of land managers, field experts, citizen scientists,
naturalists, gardeners and others interested in documenting invasive plant
occurrences in the mid-Atlantic region for the purposes of early detection,
improved management and better coordination. The region includes Delaware,
Maryland, New Jersey, New York, Pennsylvania, Virginia, West Virginia and
the District of Columbia.

By Alien Plants Have Been Mapped In European Union (Jan
Biological invasions are one of the major
threats to biodiversity and in many cases they
have considerable impact on economy and human
health. For their effective management it is
important to understand which areas and ecosystems
are at the highest risk of being invaded. The first
map of the level of alien plant invasions in
European Union (PDF | 1 MB) was published
in the Wiley-Blackwell journal Diversity and
and Survey Resourcesand Monitoring

Land managers may benefit from spending more time monitoring invasive plants
to identify those
that pose the greatest threat, according to a recent article in Invasive
Plant Science and Management. The article, "The
Rationale for Monitoring Invasive Plant Populations as a Crucial Step for Management
(Abstract)," relates results from a study by Montana State University
Nebraska Mapping programs:
- NRD Mapping Program
NRD MapMaker allows you to create rich custom maps in your web
browser from a variety of geographic data - without the need to
purchase expensive software. MapMaker is powered by GIS (Geographic
Information System) databases compiled by a variety of local, state
and Federal agencies.
- Nebraska Weed
Control Association Online Weed Management
A state-wide mapping system for all 93 counties
in Nebraska. This mapping system creates a
state-wide database of invasive plants information
and maps them using ArcIMS. Each county weed control authority
updates the information directly on the website from current inspections.
Note, this may be the first state-wide mapping
program of this type.

Become Locally Extinct As New Flora Has Moved
In (Apr 5, 2010)
Brooklyn Botantic Garden.
Dozens of flora native to the New York region face extinction, a result of urban
development and the encroachment of invasive plants from foreign lands, scientists
from the Brooklyn Botanic Garden report. Hoping to revive plants facing extinction,
scientists recently completed a 20-year project mapping species in every county
within a 50-mile radius of New York, providing detailed information on the health
of more than 15,000 native and nonnative species. See the for more information.
