Subject: INVASIVES: Final Version of the National Management Plan
The National Invasive Species Council approved the National Invasive
Species Management Plan on January 18th.  The final version of the Plan is
available on their website at http://www.invasivespecies.gov/

Invasivespecies.gov: The Nation's Invasive Species Information System
January 19, 2001 -- The final version of the National Management Plan (NMP)
is now available in PDF.
Invasivespecies.gov is a comprehensive, online information system that
facilitates access to and exchange of invasive species data and resources by
researchers, scientists, land and resource managers, public and private
sector agencies, and concerned citizens.
Next to habitat lost to land development and transformation, invasive
species pose the greatest threat to the survival of native biota in the
United States, and many other areas of the world.
Left unchecked, many invasives have the potential to transform entire
ecosystems, as native species and those that depend on them for food,
shelter, and habitat, disappear.
Consider the following:
federal officials estimate that the total costs of invasive species in the
United States are nearly $125 billion each year.
nearly half of the species listed as threatened or endangered under the
Endangered Species Act are at risk due to competition with or predation by
non-native species.
purple loosestrife, a highly aggressive plant invader of wetlands, can
produce up to 2.7 million seeds per plant yearly, and spreads across
approximately 480,000 additional hectares of wetlands each year.
the brown tree snake, an invasive originating in the South Pacific and
Australia, has extirpated 10 of 13 native bird species, 6 of 12 native
lizard species, and 2 of 3 bat species on the island of Guam.
the glassy-winged sharpshooter, an invasive insect recently arrived in
California, carries with it the plant bacterium Xylella fastidiosa, a
disease that has caused nearly $40 million in losses of California grapes.
The disease poses a major threat to grape, raisin, and wine industries, and
the tourism associated with them, collectively valued at nearly $35 billion
humans are the primary agents of dispersal of non-native species, both by
accidental and deliberate introductions.
