Cloud forests, tropical mountain forests that act as a source of water for millions, are under increasing threat from a range of factors such as climate change and golf courses, a UN report has found. The report, Cloud Forest Agenda, says that these forests abilities to strip and retain moisture from clouds and fog is vital to abundant, clean and predictable water supplies in many areas, especially during dry seasons. For example, the cloud forests of La Tigra National Park in Honduras provide over 40% of the water for the 850,000 people living in the capital, Tegucigalpa.
