The remaining forests cover only 4.6 percent of the wet zone. Between 1990 and 2005, Sri Lanka has showed one of the highest deforestation rates of primary forests in the world. A survey carried out in 2005 found that 17 of Sri Lanka's frogs have become extinct in the past decade and another 11 species face imminent threat of extinction unless their habitat is secured. These remaining forests exist as highly fragmented patches. Most of them are less than in extent. Poaching and the extraction of forest products (timber, firewood, medicinal plants) are a problem in almost all forest reserves. Nevertheless, if the existing forests are preserved the condition can be improved, as many of the species of this ecoregion have small habitat needs. There are several protected areas that overlap with the ecoregion. The two most notable are the world heritage site the Sinharaja Forest Reserve and the Peak Wilderness Sanctuary. Altogether, protected areas of this ecoregion accounts for only .
