Ecoregions of North America, featuring the 50 United States, the District of Columbia and the five inhabited territories. 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.
Each ecoregion is classified into one of 14 major habitat types, or biomes. In 2017 the WWF team revised ecosystem names and boundaries in the Arabian Peninsula, drier African regions, and Southeastern United States.
This climate is characterized by relatively even temperatures throughout the year, and a pronounced dry season. The driest month has less than 60 mm of precipitation, and is drier than the average month. [4] [5] Annual rainfall is less than 1,500 mm in most of the region, and as low as 800 mm. [1]
The biome includes several types of forests: Lowland equatorial evergreen rain forests, commonly known as tropical rainforests, are forests which receive high rainfall (tropical rainforest climate with more than 2000 mm, or 80 inches, annually) throughout the year. [5]
The ecoregion consists of an area of plateau and low river basin in Cambodia, Thailand, Laos, Vietnam and Myanmar and includes: . In Thailand the large Khorat Plateau, the higher elevation plains of the Chao Phraya River basin, the foothills of the Tenasserim Hills and other dry areas of the lower slopes of the Khun Tan, Phi Pan Nam and Phetchabun mountain ranges of the north of the country.
All of these cold deserts experience about 100–300 mm of precipitation in a year indicating a semi-arid climate. The warm deserts of North America include The Mojave Basin and Range, the Sonoran desert, and the Chihuahuan desert. These areas have a tropical desert climate, and are known as the hottest and driest place on the continent.
The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between 90–150 centimetres (35–59 in) per year. [1] Rainfall can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions.
