CABI is a non-profit organization specializing in scientific publishing, research, and communication. CABI improves people's lives worldwide by providing information and applying scientific expertise to solve problems in agriculture and the environment.

Cooperative Research Centre (CRC) for Australian Weed Management 
The CRC brings together researchers and research users from universities, the public sector and business to undertake long-term, collaborative research and develop ventures that serve national objectives. The CRC is working to reduce the risks posed by current and new weed incursions through programs in research, education and information delivery across Australia.

Delivering Alien Invasive Species Inventories Europe (DAISIE) 
DAISIE - Delivering Alien Invasive Species Inventories Europe - is an online database of more than 11,000 alien species occuring in Europe, links to 2000 experts on biological invasions, and information on specific regions threatened by invasive alien species.

Department of Primary Industries (DPI), Agriculture & Food, Weeds & Pests, Victoria, Australia
The DPI conduct a variety of projects that support agriculture and natural resource management efforts, including invasive plant management. Working from a preventative approach, weed specialists provide analysis on “Candidate Weeds” to help predict the next outbreak. Policies and programs have been developed based on population growth data for prevention and containment of invasive weeds. The website has an A-Z listing of weeds, information on the “Weed Spotters” program to identify new weeds, initiatives to tackle weeds on private land, and up-to-date newsletters called “Under Control” that documents progress.

DST-NRF Centre of Excellence for Invasion Biology, South Africa 
The CIB is an inter-institutional Centre of Excellence established in 2004 within the DST-NRF Centres of Excellence Programme. Its members undertake research on the biodiversity consequences of biological invasions, largely through post-graduate student training. The principal aims of the Centre's work are to reduce the rates and impacts of biological invasions by furthering scientific understanding and predictive capability, and by developing research capacity. The CIB has its physical home at the University of Stellenbosch, but comprises a network of senior researchers and their associated postdoctoral associates and graduate students throughout South Africa.

Global Invasive Species Database (GISD) 
The Global Invasive Species Database (GISD) aims to increase awareness about invasive alien species and to facilitate effective prevention and management activities. The GISD focuses on invasive alien species that threaten native biodiversity and covers all taxonomic groups from micro-organisms to animals and plants in all ecosystems. Species information is either supplied by or reviewed by expert contributors from around the world.

Great Britain Non-Native Species Secretariat (NNSS) 
NNSS in England, Scotland and Wales have launched the first co-ordinated strategy in May 2008 to reduce the threat to Britain’s native biodiversity from invasive non-natives species.

Horus Institute, Brazil
The Horus Institute was founded in 2002 to work on biological invasions in Brazil. Their mission is to develop alternatives in environmental conservation integrated with social and economic development, production systems and the daily life of people. This site has invasive species factsheets, an image database, and information on case studies, forums, and control measures used at multiple sites.
