Finally to Clare Billington, Willem Ferwerda, Larry Hamilton and Richard Luxmoore for their advice and encouragement along the way. Many thanks are also due to those who commented on a draft layout for the database and on types of information to be collected, as well as giving advice and guidance during this phase of work. They include Sampumo Bruinzeel, Rainer Bussmann. Charles Doumenge, Willem Ferwerda, Don Gilmour, Larry Hamilton, Mark Jeffcote, Jim Juvik, Maarten Kappelle. Mariella Leo, Adrian Long, Chris Sharpe, Fred Scatena, Ed Tanner. Paul Toyne, Peter Weaver, Tim Whitmore, Jan Wolf, and many colleagues here at WCMC. In addition thanks to all the cloud forest enthusiasts around the world who have contributed information and expressed an interest in working with WCMC in raising awareness of the value of remaining cloud forests. Many are listed along with their contact details as an annexe to this directory. Apologies to any that have been missed. We trust that this draft directory and the database from which it has been compiled provide a valuable resource. We also hope to build on this and the rapidly developing network of contacts in a subsequent phase of work, which will contribute towards the conservation of the remaining areas of this unique and fragile ecosystem. The World Conservation Monitoring Centre (WCMC). based in Cambridge. UK is a joint-venture between the three partners in the World Consen'ation Strategy and its successor Caring For The Earth: lUCN - The World Conservation Union. UNEP - United Nations Environment Programme, and WWF - World Wide Fund for Nature.

Much of their value is related to their unique characteristics of biodiversity and endemism and the functions that they provide. If managed sustainably, TMCFs can provide a valuable range of services to local populations living in or adjacent to the forest. As well as being a source of fuelwood and small dimension timber, they may provide a range of non-wood forest products including honey, medicinal plants and bushmeat. 1.1 Values The hydrological role of TMCFs through their water stripping function gives them a value in terms of water resources that is quite distinct from other forests or types of land use (Stadtmuller, 1987, quoted in Hamilton et al. 1993). Tree crowns act to intercept wind- driven cloud moismre on leaves and branches which drips to the ground, resulting in the addition of water to the hydrological system. As a result TMCFs play an important role in watershed protection by maintaining ground cover, thus minimising soil erosion and providing a regular and controlled supply of water to communities living downstream. TMCFs also make excellent ecosystems and sites for monitoring climate change and air quality due to their relatively undisturbed tropical location. In addition to having a wealth of biological diversity which has been previously undervalued, TMCFs possess a very high proportion of endemic species, and probably many more as yet unknown to science. Many TMCF areas serve as refugia for endangered species which are being marginalised by the transformation and/or destruction of ecosystems at lower elevations. Throughout the tropics, the TMCF zone provides habitat for notable plant species such as tree ferns {Cyatheaceae) and many rare and endemic orchids (Orchidaceae) along with other economically valuable plants and tree species. TMCFs are also the last remaining habitat for many threatened species of mammals and birds. According to Long (1993), 260 of the world's nationally endemic bird species have cloud forest habitats. With this wealth of diversity, cloud forest areas are becoming an increasingly important draw for ecotourism, such as bird watching holidays, and for local education and recreation. However while such activities may provide a valuable source of income, they must be carefiilly managed in order to help conserve the unique environment and benefit local communities. 1.2 Threats/Pressures Despite their considerable value, these fragile habitats are under increasing threat from a wide range of sources. In particular, human population pressures have forced the conversion of more marginal and previously less accessible areas for both subsistence and cash crops, including legal or illegal drug plant production. Many areas are under pressure from encroachment by livestock or have already been cleared to provide new grazing land TMCFs may also provide a valuable source of fuelwood and small dimension timber, along with a range of non-wood forest products, but in many areas such exploitation has reached unsustainable levels resulting in irreversible damage to the forest habitat. The same is true for hunting or capture of fauna (for sport, subsistence or commercial trade), and tourism and recreation. Plans for new road building projects threaten many remaining TMCFs, along with mining and geothermal development schemes many of which are well established.
