AlgaeBase is a database of information on algae that includes terrestrial, marine and freshwater organisms. At present, the data for the marine algae, particularly seaweeds, are the most complete. For convenience, we have included the sea-grasses, even though they are flowering plants.

This page provides a distribution map of alligator weed in Australia. Also marked on the map are the different statuses of management actions undertaken in different areas.

This inventory and assessment is based on experts’ consultation, literature and field studies in collaboration with local partners such as high schools, community forest user groups, community-based NGOs, farmers and other stakeholders.

The Baltic Sea Alien Species Database is an interactive tool, and offers several information retrieving options: Database Search, Baltic Sub-regions, and Species Directory. Information from the Database is obtained from members of the Baltic Marine Biologists Working Group on Non-Indigenous Estuarine and Marine Organisms, as well as from other researchers of invasive species biology. Published papers, grey literature, environmental reports, other internet sites and the Database Questionnaire also provide information. Objectives and goals of the Database include: to provide a qualified reference system on alien species for the Baltic Sea area, to update information on the Baltic Sea alien species, to encourage the exchange of data among different geographical regions and thereby to serve a node in the Global Information System for Invasive Species.

The CIESM Atlas of Exotic Species is the first attempt to provide a comprehensive, group by group, survey of recent marine "immigrants" in the Mediterranean, which is undergoing drastic and rapid changes to its biota. Many of these new species are of Indo-Pacific origin having reached the Mediterranean Sea through the Suez Canal: these so called "Lessepsian" migrants now contribute significantly to the biodiversity of the Eastern basin. With increasing attention paid to this phenomenon, invaders of other origin-notably from the tropical Atlantic realm- are now more frequently recognized as well, a result of a natural invasion through the Gibraltar straits or of introduction (accidental or intentional) by man.

The Atlas is a guide for researchers, environmental planners and non-specialists who are interested in or likely to encounter marine species that are not native to the basin.

For each pest, it is possible to obtain lists of host plants, commodities able to act as pathways in international trade, details of geographical distribution with maps, and pictures. Conversely, it is also possible to interrogate the database to obtain specific lists of pests, by stipulating the host species, the commodity, and the countries of interest. PQR contains general nomenclatural and taxonomic details on pests and hosts.

The Global Biodiversity Information Facility (GBIF) was established by governments in 2001 to encourage free and open access to biodiversity data, via the Internet. Through a global network of countries and Organisations, GBIF promotes and facilitates the mobilization, access, discovery and use of information about the occurrence of organisms over time and across the planet.
In addition to data, distribution maps based on the data mediated through GBIF are produced on site, and can be delivered to other sites. The GBIF site also allows the data to be downloaded as placemarks for Google Earth. GBIF – mediated data also provides the maps in Encyclopedia, developed by a mapping tool created with Vizzuality.

The site provides a number of resources including the invasive and introduced trees database, species profiles for forest pests, pest management options and links to a number of other FAO publications. An integral part of sustainable forest management is measures to protect forests from natural threats such as fire, insects and diseases. Increasingly, an additional and more severe threat has been affecting the forest sector worldwide - invasive species. Invasive species are any species that are non-native to a particular ecosystem and whose introduction and spread causes, or are likely to cause, socio-cultural, economic or environmental harm or harm to human health. "

Focused on the threat of invasive species on native species and ecosystems on islands. The site enables users to search the database directly by species, or by location, or by impacts of invasive species and their outcomes on native populations. With each species entry, there is an invasive threat summary, and a threat management summary detailing possible conservation strategies and past case studies. IBIS was developed by the IUCN SSC Invasive Species Specialist Group in response to feedback from island conservation managers that there was a need for better access to data and information on invasive alien species on islands and how to manage this insidious threat. IBIS aims to record and provide information on the impacts of invasive alien species on native species on islands (with a focus on those that are classified as ‘threatened’ in the IUCN Red List of Threatened Species- Critically Endangered (CR), Endangered (EN) and Vulnerable (VU)), and the management of this threat.

Weeds of National Significance are declared based on their invasiveness, impacts, potential for spread and significant environmental and socioeconomic impacts. African boxthorn ticks all these boxes, and in 2012 was declared a Weed of National Significance. This Strategic Plan provides guidance for the first five years of implementing a nationally coordinated approached to managing African boxthorn.

National Invasive Species Strategy, Action Plan and Policy Guidelines for Uganda This project aims to reduce and possibly remove barriers to the management of IAS through effective implementation of CBD Article 8(h) in 4 pilot countries (Ethiopia, Ghana, Uganda, Zambia), using a multisectoral ecosystem approach. In each country an enabling policy environment will be promoted through the establishment of appropriate institutional arrangements to ensure that IAS strategies are mainstreamed; stakeholder awareness of IAS issues will be raised and access to necessary information provided; prevention and control programmes will be established, including ecosystem management at pilot sites where IAS threaten biodiversity; capacity for sustainable IAS management will be built. Lessons learned will be disseminated for replication in other countries in Africa.

The North American Invasive Species Network (NAISN) is an American 501(c)3 non-profit organization that was formed in 2010 by university and government scientists from across North America. The countries of Mexico and Canada participate as NAISN members through a Memorandum of Understanding. Membership is targeted toward regional university centers and institutes, government institutions, non-profit organizations, research labs, and/or other groups and individuals with invasive species interests and qualifications that are valuable to the mission of NAISN. Because invasive species cross governmental jurisdictional boundary lines, NAISN aims to unify and connect existing regional invasive species efforts into a single network to improve communication, collaboration, and overall coordination to help current invasive species management and prevention efforts across the continent.
