Tanna island is a biodiversity hotspot in Vanuatu with 11 endemic plants found (UNDP land holders Project Report 2006) that have local use. Increasing population couple with the increase slash and burning of natural vegetation to gardening for food crops resulted unintentional removal of significant plants. The loss of forest and fallow period of gardening are becoming shorter each year is potentially leading to land degradation on the island. Many riverine streams in the island have drainage that have coverage of large part of forest land areas but due to the high due to loose soil structure that it limited to hold water at surface are shorter streams. Local people needed to be empowered to mainstreamed forest protection in their daily livelihood to support global biodiversity protection and mitigate climate change. Thus in Katalaei community, the project will continue to build local capacity for forest biodiversity protection through demonstration local protection of water catchment clean water supply for the local community. Knowledge generated will help build local knowledge on forest biodiversity in Tanna
