What are the protective functions of forests?
Trees quite literally form the foundations of many natural systems. They help to conserve soil and water, control avalanches, prevent desertification, protect coastal areas and stabilize sand dunes. Forests are the most important repositories of terrestrial biological biodiversity, housing up to 90 per cent of known terrestrial species. Trees and shrubs play a vital role in the daily life of rural communities. They provide sources of timber, fuel wood, food, fodder, essential oils, gum, resins and latex, medicines and shade. Forest animals have a vital role in forest ecology such as pollination, seed dispersal and germination.
