IUCN
The International Union for Conservation of Nature (IUCN) is a membership Union uniquely composed of both government and civil society organisations. By harnessing the experience, resources and reach of its more than 1,400 Member organisations and the input of some 15,000 experts, IUCN is the global authority on the status of the natural world and the measures needed to safeguard it.
IUCN SSC
The Species Survival Commission (SSC) is a science-based network of thousands of volunteer experts from almost every country in the world, all working together toward achieving the vision of “a just world that values and conserves nature through positive action to both prevent the loss and aid recovery of the diversity of life on earth.”
IUCN SSC Invertebrate Conservation Committee
The mission of the Invertebrate Conservation Committee is to foster the conservation of terrestrial and freshwater invertebrates and their habitats around the world, and to assess their conservation status, raise awareness and engage in practical conservation of these most species-rich taxonomic groups on Earth.

The IUCN Red List
Established in 1964, The International Union for Conservation of Nature’s Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.
The IUCN Red List is a critical indicator of the health of the world’s biodiversity. Far more than a list of species and their status, it is a powerful tool to inform and catalyze action for biodiversity conservation and policy change, critical to protecting the natural resources we need to survive. It provides information about range, population size, habitat and ecology, use and/or trade, threats, and conservation actions that will help inform necessary conservation decisions.
