The IUCN has a comprehensive site on bio-diversity and invasive alien species.
This includes an Overview
which includes basic information on the nature and extent of the problem on
a global scale; a 'Spotlight'
on particular current issues; a paper on Control
Options for Fresh-water Invasives; guidelines on policy development related
to invasives which includes the following links:-
Policy
Working
for Water Program - South Africa. Vision - "The
Working for Water programme will sustainably control invading alien
species, to optimise the potential use of natural resources, through the process
of economic empowerment and transformation. In doing this, the programme will
leave a legacy of social equity and legislative, institutional and technical
capacity."

The
Global Invasive Species Programme (GISP) is coordinated by, the Scientific
Committee on Problems of the Environment, in collaboration with the World
Conservation Union, the Center for Agriculture and Biosciences International
and the United Nations Environment Programme. GISP is a component of
DIVERSITAS, an international
programme on biodiversity science.
US Government "Invasivespecies.gov"
is the gateway to US Federal efforts concerning invasive species. On this
site you can learn about the impacts
of invasive species and the Federal government's response,
as well as read select species
profiles and find links to agencies
and organizations dealing with invasive species issues. Invasivespecies.gov
is also the website for the National
Invasive Species Council.
The
Invasive Species Specialist Group (ISSG) is part of the Species Survival Commission
(SSC) of the World
Conservation Union (IUCN). The ISSG is
a global group of 146 scientific and policy experts on invasive species from
41 countries. In addition to its headquarters in Auckland, New Zealand, ISSG
has three regional sections in North America, Europe, and South Asia. ISSG
provides advice on threats from invasives and control or eradication methods
to IUCN members, conservation practitioners, and policy-makers. The group's
activities focus primarily on invasive species that cause biodiversity loss,
with particular attention to those that threaten oceanic islands.

The
Northeast-Midwest Institute is undertaking numerous efforts to prevent the
introduction and spread of nonindigenous aquatic nuisance species--such as
zebra mussels, Eurasian ruffe, and sea lampreys--that destroy ecosystems and
threaten the economic stability of the region's industries and municipalities
that rely on water. The Institute has been active in four main arenas: congressional
authorizing and appropriating legislation to prevent and control the spread
of aquatic nuisance species; oversight of program implementation; ship-board
technology development to stop the transfer of organisms into the waters of
the United States; and development of an international convention on ballast
water management as part of the United Nation's International Maritime Organization.
