UNEP-WCMC, in association with the IUCN Species Survival Commission and a network of experts, identified over 8000 tree species which are threatened with extinction at a global level. This survey, supported by the Government of the Netherlands as part of the Conservation and Sustainable Management of Trees project, is the first of its kind to assess the conservation status of tree species worldwide. Information on individual species is recorded in the Tree Conservation Database and includes IUCN red list category, information on distribution, uses, ecology, threats and conservation measures. Summary information on individual species is published in The World List of Threatened Trees.

UNEP-WCMC and Fauna and Flora International have recently joined together to form the Global Trees Campaign. By using the information resources available in the Trees Conservation Database and through collaboration with experts and organisations around the world, the Global Trees Campaign will act to save the world's most threatened trees.
