This summary document outlines the need for spatial data on tree species as a tool for conservation action. It introduces plans for a tree species mapping programme that will build on the forest mapping information management expertise of UNEP-WCMC. A Global Tree Conservation Atlas will be one of the main outputs of the Global Trees Campaign. The Campaign focuses on trees as flagship species for conservation of ecosystems and landscapes, and enables local people to carry out rescue and sustainable use operations. Working in partnership with organizations around the globe, the Global Trees Campaign aims to save the world's most threatened tree species and their habitats through information, conservation and wise use. The Campaign is a partnership between Fauna & Flora International and UNEP-WCMC.
