Deforestation of tropical wet forests has caused many native species to become endangered or extinct at an alarming rate. The Tropical Wet Forests around the globe are being deforested at an alarming rate. For example, some counties like Florida have lost 50% [33] of their tropical wet forest habitat, and Costa Rica has lost about 90%. [34]
The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
The World's 100 most threatened species [1] is a compilation of the most threatened animals, plants, and fungi in the world. It was the result of a collaboration between over 8,000 scientists from the International Union for Conservation of Nature Species Survival Commission (IUCN SSC), along with the Zoological Society of London .

Endangered species include the Coast Fontainea and the Scented Acronychia. Ferns are less often seen than in nearby sub-tropical rainforests. Non rainforest species are occasionally seen in these forests, such as the Coast Banksia (Banksia integrifolia) and Bangalay (Eucalyptus botryoides). [1]
A single hectare of rainforest may contain 42,000 different species of insect, up to 807 trees of 313 species and 1,500 species of higher plants. [5] Tropical rainforests have been called the " world's largest pharmacy ", because over one quarter of natural medicines have been discovered within them.
The regions with the highest tropical deforestation rate between 2000 and 2005 were Central America—which lost 1.3% of its forests each year—and tropical Asia. [49] In Central America, two-thirds of lowland tropical forests have been turned into pasture since 1950 and 40% of all the rainforests have been lost in the last 40 years. [66]
The biodiversity of plant species is the highest on Earth with one 2001 study finding a quarter square kilometer (62 acres) of Ecuadorian rainforest supports more than 1,100 tree species. [54] A study in 1999 found one square kilometer (247 acres) of Amazon rainforest can contain about 90,790 tonnes of living plants.
The Tropical Rainforest of Sumatra has just recently become a part of the World Heritage List, in 2004. 2.5 million hectares of Sumatra's rainforests were included on the World Heritage List of the UN Educational, Scientific and Cultural Organization (UNESCO) because of their rich and different biodiversity.
