Most of Samoa's land is under
customary ownership, about 81% of which is governed at the local level by
matai, the chiefly heads of families. Conservation projects therefore take place in partnership with
matai, such as the lowland rainforest preserve in
Falealupo village, at the western tip of Savai'i and
Tafua village on the south east coast. Some of the islands' plants are used for food, fiber, and traditional Samoan medicine (see
Samoan plant names). In 1994,
Samoa ratified the international and legally binding treaty, the
Convention on Biological Diversity to develop national strategies for conservation and sustainable use of
biological diversity. By 2010 protected areas in the country covered 5% of land. Protected areas include
Cornwall National Park (24.94 km2),
Lata National Park (49.92 km2), and
Mauga o Salafai National Park (59.73 km2) on Savai'i,
Lake Lanotoo National Park (4.7 km2) and
O Le Pupu-Puʿe National Park (50.19 km2) on Upolu, and the
National Park of American Samoa on
Tutuila,
Ofu, and
Ta‘ū. ==Gallery==
