As of the writing of the plan in 2008, 19% of Ecuador's land area was in a protected area; however, the plan also states that 32% of the land must be protected in order to truly preserve the nation's biodiversity. Current protected areas include 11 national parks, 10 wildlife refuges, 9 ecological reserves, and other areas. A program begun in 2008, Sociobosque, is preserving another 2.3% of total land area (6,295 km2, or 629,500 ha) by paying private landowners or community landowners (such as Amerindian tribes) incentives to maintain their land as native ecosystems such as native forests or grasslands. Eligibility and subsidy rates for this program are determined based on the poverty in the region, the number of hectares that will be protected, and the type of ecosystem of the land to be protected, among other factors. Ecuador had a 2018 Forest Landscape Integrity Index mean score of 7.66/10, ranking it 35th globally out of 172 countries.
