Rainforests are ecoregions that typically receive between 180 to 210 centimeters of rainfall per annum. These forest types typically have canopies that attain heights of 30 to 45 meters. Rainforests may occur in tropical or temperate zones, but are customarily characterized by elevated levels of endemism and species richness. Sunlight penetration to the forest floor is a minimal quantity, generally less than two percent of the canopy value.
Atlantic Equatorial coastal forestsLast Updated on 2013-12-31 17:26:01The Atlantic Equatorial Coastal Forests ecoregion has exceptionally high levels of species richness and endemism, contains large blocks of evergreen lowland moist forest, and the central portion has one of the lowest human population densities in Africa. Most of the floral and faunal assemblages are intact, including assemblages of threatened large mammals, such as the western lowland gorilla (Gorilla gorilla gorilla), mandrill (Mandrillus sphinx), and sun-tailed monkey (Cercopithecus solatus). Important centers of endemism are found in this ecoregion, particularly in some of the coastal mountain ranges.
This ecoregion extends from the Sanaga River in west-central Cameroon south through Equatorial Guinea into the coastal and inland areas of Gabon, the Republic of Congo, and the Cabinda Province of Angola, ending in the extreme west Democratic Republic of Congo, just north of the... More »
Cuban moist forestsLast Updated on 2013-12-05 19:18:08The Cuban moist forests originally held exceptionally distinctive insular flora and fauna, with many species, genera and families unique to its forests in the form of relict taxons. The island’s long-standing isolation has made it possible for these relict taxons to speciate, and many unique groups have also diversified. Many of the old lines that survive in these forests are extinct on the nearby continents. The rich flora and diverse fauna should be pointed out, particularly land snails. At present, these forests are mostly destroyed and fragmented. Expansion in the production of cacao, coffee and tobacco as well as mining and other human activities represent a serious threat in some areas.
Originally, this ecoregion was distributed in multiple patches of different sizes along the ranges and highlands of the island of Cuba (located between 19º50’N to... More »
Petén-Veracruz moist forestsLast Updated on 2013-11-19 15:02:16The Petén-Veracruz moist forests is a moist broadleaf forest ecoregion in mostly mountainous terrain that extends through most of Belize northward through parts of Guatemala and into southern Mexico. This forested ecoregion covers an area of approximately 149,100 square kilometres. Endemism of this ecoregion is moderate, with amphibian endemism particularly notable, and overall species richness is high; vertebrate taxa found here, for example, total 988 species.
This ecoregion is classified as critically endangered due to relentless encroachment of the human population, particularly from the human overpopulated portions of the forests that lie in Guatemala and southern Mexico; conversely, the nation of Belize has kept its population within the land's carrying capacity and has a strong national ethic of environmental protection. The ecoregion is situated within the... More »
Isthmian-Atlantic moist forestsLast Updated on 2013-11-10 13:56:46Covering the lowland Atlantic versant at chiefly below 500 metres elevation in southern Nicaragua, northern Costa Rica, and most of Panama, the Isthmian-Atlantic moist forests represent the epitome of wet, tropical jungle. This forest ecoregion evolved from unique combinations of North American and South American flora and fauna, which came together with the joining of these continents around three million years before present.
The ecoregion is classified to be within the Tropical and Subtropical moist broadleaf forests biome. Currently, much of this ecoregion has been converted to subsistence and commercial agriculture. The Isthmian-Atlantic moist forests exhibit a high level of species richness, with 1021 vertebrate taxa alone having been recorded here, with a particularly vast assortment of amphibians, many of which are endemic or near endemic; moreover, among the amphibians there...

Admiralty Islands lowland rainforestsLast Updated on 2013-11-05 14:31:57The Admiralty Islands Lowland rainforests contain several endemic species, yet the biodiversity of these islands is still poorly known. Intensive commercial logging and conversion of forests to agriculture are the greatest threats to the ecoregion.
The Admiralty Islands are located slightly north of Papua New Guinea (PNG) in the southwest Pacific Ocean and are often grouped together with New Britain and New Ireland to make up the Bismarck Archipelago. The Admiralty Islands form the political unit of Manus Province, PNG. Manus Province is the smallest province of PNG in both land area and population (32,713). The temperature of the Admiralty Islands varies little throughout the year, reaching daily highs of 30-32° Celsius and 20-24°C at night. Average annual rainfall is 3382 millimeters (mm) and is somewhat seasonal, with June through August being the wettest... More »
