Dry forests represent a biome that occurs in the tropics and sub-tropics, consisting of a chiefly deciduous tree mix. The climate consists of not only of less rainfall than most other forest types, but contains a long dry season. Endemism is often high, not only of plant species, but also vertebrates.
Sierra Madre de Oaxaca pine-oak forestsLast Updated on 2014-04-23 17:49:46The Sierra Madre de Oaxaca pine-oak forests ecoregion of northern Oaxaca, Mexico exhibits a large number of endangered species, so that their conservation value is outstanding in terms of uniqueness of habitat that supports these species. The Sierra Madre de Oaxaca pine-oak forests is within the Tropical and Subtropical Conifer Forests biome, and the ecoregion is known for elevated plant endemism, especially within the Sierra de Juarez montane forests. Indigenous peoples have long used the land extensively for agriculture and cattle farming.
This ecoregion is located in northern Oaxaca State, and is delineated by the Sierra Norte de Oaxaca Mountains, which have characteristically abrupt and rugged topography. Its tallest peak is Zempoaltepetl (3400 metres), and most of the terrain in this area is above 1000 metres. Three mountain chains or sierras constitute the Sierra Madre... More »
Windward Islands dry forestsLast Updated on 2014-04-23 17:04:52The Windward Islands dry forests ecoregion is sparsely distributed among the Windward Island Group of the Caribbean’s Lesser Antilles. It is typically found as an intermediate gradient between the more mesichabitat characterized by moderate soil moisture, high-elevation forests and the xeric, coastal areas. Much of this ecoregion has been substantially altered by shifting cultivation. Many areas that were once dry evergreen or semi-evergreen seasonal forest, are now cultivated and dominated by farms, rural villages, roads, pastures and banana tree patches. This ecoregion shares flora and fauna with adjacent moist forests and, in some areas, with species native to coastal habitats. Arid coastal areas and inaccessible interior mountains put a disproportionate amount of human-related pressures (i.e., agricultural expansion, roads, buildings) on this ecoregion. Consequently,...

Trinidad and Tobago dry forestsLast Updated on 2014-04-23 17:00:38The Trinidad and Tobago dry forests are found on the Caribbean Islands of Trinidad and Tobago. Due to recent separation from South America these islands' flora and fauna reflect the ecology of equatorial South America more than any other Windward Island where biotic endemism is common. On Trinidad, this ecoregion’s proximity to Port of Spain, the industrial and commercial center and focal point for tourism in the country, has predisposed it to significant agricultural and industrial alterations. As much as 13% (69,000 hectares (ha)) of the land area in Trinidad and Tobago has been proposed for protected areas status, portions of which are included within this ecoregion. Official Government approval is still pending however, recent trends indicate an environmentally conscious direction for the islands’ natural resources.
This ecoregion covers only a small portion... More »
Sierra de la Laguna dry forestsLast Updated on 2014-04-23 16:56:19
Located at the southern end of the Baja California Peninsula in Mexico, the Sierra de la Laguna dry forests ecoregion was once an isolated island, containing a large number of endemic species. After sufficient mountain uplift and the joining the Baja Peninsula mainland, this ecoregion underwent significant speciation, and is thus today high in species diversity; this portion of the peninsula contains the majority of the species found in the southern part of the Baja Peninsula. The Sierra de la Laguna dry forest is a subtropical dry forest classified within the Tropical and Subtropical Broadleaf Forests biome; the ecoregion is threatened by overgrazing from domestic cattle and the hunting by humans. Designated as a Protected Natural Area (PNA), this important ecoregion is at risk from habitat... More »
Maracaibo dry forestsLast Updated on 2014-04-23 16:48:42
The Maracaibo dry forest is no exception to the widespread degradation and conversion of neotropical dry forests caused by agriculture and grazing. The Maracaibo ecoregion falls within the principal oil producing region of Venezuela, which is one of its most degraded regions.
The Maracaibo dry forests are located in the northeastern coastal area of Venezuela. The majority of the ecoregion is located in the state of Zulia in the Maracaibo Basin; the remainder lies in the state of Trujillo. The ecoregion borders the Sierra de Perijá to the west, and the Cordillera de Mérida and the Sierra of Baragua to the south and northeast respectively. There are also patches of mangrove habitat interspersed along the shores of Maracaibo Lake, in the interior of the ecoregion. A major network of roads extends through the basin; one of these roads is the Pan American Highway.... More »
