Tropical and subtropical dry forests can be found in Mexico, south-eastern Africa, India, Indochina, Madagascar, South America, and the Pacific.
|The global distribution of tropical and subtropical dry broadleaf forest as determined by Olson et al, 2001|
Because of the dry period, a higher proportion of the vegetation are deciduous, where the shedding of leaves allows them to reduce water loss. The loss of leaves also means that, for a period, more sunlight reaches the forest floor, thereby allowing more species to occur lower in the canopy and on the ground. Despite the dry period, tropical and subtropical dry forests still have very high levels of biodiversity.
Tropical and subtropical dry forests are also at risk of deforestation and degradation, and at greater risk of burning due to the drier climates they experience. However, species are better adapted to dry periods than those of moist forest making them more resilient to changes in rainfall patterns such as drought.
