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
However, tropical forests are extensive, making up just under half the world's forests. [3] The tropical domain has the largest proportion of the world's forests (45 percent), followed by the boreal, temperate and subtropical domains. [4] More than 3.6 million hectares of virgin tropical forest was lost in 2018. [5] [6]

More than half of all plant and land animal species in the world live in tropical forests. [21] As a result of deforestation, only 6.2 million square kilometres (2.4 million square miles) remain of the original 16 million square kilometres (6 million square miles) of tropical rainforest that formerly covered the Earth.

Under the Endangered Species Act in the United States, "threatened" is defined as "any species which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range". [12] It is the less protected of the two protected categories.
Species evenness is the relative number of individuals of each species in a given area. [181] Species richness [182] is the number of species present in a given area. Species diversity [183] is the relationship between species evenness and species richness. There are many ways to measure biodiversity within a given ecosystem.
