Distribution of tropical wet forests. Tropical plants and animals are those species native to the tropics. Tropical ecosystems may consist of tropical rainforests, seasonal tropical forests, dry (often deciduous) forests, spiny forests, deserts, savannahs, grasslands and other habitat types.
This is a list of terrestrial ecoregions as compiled by the World Wildlife Fund (WWF). The WWF identifies terrestrial , freshwater , and marine ecoregions . The terrestrial scheme divides the Earth's land surface into 8 biogeographic realms , containing 867 smaller ecoregions.
Tropical forests are often thought of as evergreen rainforests [2] and moist forests, but these account for only a portion of them (depending on how they are defined – see maps). The remaining tropical forests are a diversity of many different forest types including: Eucalyptus open forest, tropical coniferous forests, savanna woodland (e.g ...
Tropical rainforests are among the most threatened ecosystems globally due to large-scale fragmentation as a result of human activity. Habitat fragmentation caused by geological processes such as volcanism and climate change occurred in the past, and have been identified as important drivers of speciation. [ 10 ]
The following is a list of ecoregions in the United States as identified by the World Wide Fund for Nature (WWF). The United States is a megadiverse country with a high level of endemism across a wide variety of ecosystems.
List of ecoregions in North America (CEC) List of ecoregions in the United States (EPA) Ecoregions of the world defined by the conservation group World Wildlife Fund (WWF) : Global 200 ecoregions (WWF), 238 single or combined ecoregions identified by the World Wildlife Fund (WWF) as priorities for conservation.
The WWF published Freshwater Ecoregions of the World, a global map of freshwater ecoregions. The WWF team identified ten freshwater ecoregions for Australia and Tasmania. A major habitat type, or biome, was identified for each ecoregion.
The following is a list of marine ecoregions, as defined by the WWF and The Nature Conservancy. The WWF/Nature Conservancy scheme groups the individual ecoregions into 12 marine realms, which represent the broad latitudinal divisions of polar, temperate, and tropical seas, with subdivisions based on ocean basins.
