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:-


logo 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." .

Darwin Foundation - For information and articles on invasive species from the Darwin Foundation, visit this site:  

 National Park Service  Good definitions of what is invasive, why they are a problem, what you can do (USA context). 

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.

Invasive Species Specialist GroupThe 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.


Information on invasives in the USA.


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.
