How we engage

Species are critical for a healthy planet, but growing pressures from human activities are putting them at risk of extinction. Habitat destruction, invasive species, overexploitation, illegal wildlife trade, pollution and climate change are threatening the survival of species worldwide.

IUCN is at the forefront of the global fight to save species from extinction. Its Species Survival Commission has over 9000 members, within 160 Specialist Groups. The IUCN Red List of Threatened Species™ is used to guide decision making and conservation action. IUCN provides technical expertise for conservation issues and projects.

  • Guam Rail The flightless, fast-running Guam Rail (Hypotaenidia owstoni) – the second bird in history to recover after being declared Extinct in the Wild, after the California Condor (Gymnogyps californianus). Once widespread on the Pacific island of Guam, its numbers declined after the Brown Tree Snake (Boiga irregularis) was accidentally introduced at the end of World War Two. In 1987, the last wild Guam Rail was killed by this invasive predator. Thanks to a 35-year captive breeding programme, the Guam Rail is now established on the neighbouring Cocos Island. However, the bird is still classified as Critically Endangered – one step away from extinction. Photo: Photo by Josh More (CC BY-NC-ND 2.0)
