The Tehuantepec-El Manchon mangroves ecoregion (WWF ID:NT1435) covers a series of mangrove woodlands along the Pacific Ocean coast of the state of Chiapas, Mexico. The ecoregion is relatively large and continuous, with trees up to 25 meters in height. The region supports stands of a type of yellow mangrove (Rhizophora harrisonii) that normally only grown further south. The coast of Mexico here is wet - over 2,500 mm/year of rain. Four RAMSAR wetlands of international important are found in the zone, and a UNESCO Biosphere Reserve (the La Encrucijada Biosphere Reserve). Of particular importance are the wide variety of permanent and migratory birds in the area.[1][2][3]

Location and description[]

The mangrove sites of this ecoregion run almost continually along a 260 km stretch of the Pacific Coastal Plain, along the length of the state of Chiapas. This plain is at the foot of the Sierra Madre de Chiapas mountains and is mostly flat. For the western-most 50 km, the ecoregion immediately inland is the Southern Pacific dry forests. Further east and south the interior ecoregion is the Central American dry forests ecoregion.

Climate[]

The climate of the ecoregion is Tropical savanna climate - dry winter (Köppen climate classification (Aw)). 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] Precipitation averages 2,500-3,000 mm/year.[1]

Flora and fauna[]

The characteristic mangrove tree species of the region are Red mangrove (Rhizophora mangle), white mangrove (Laguncularia racemosa), yellow mangrove (Rhizophora harrisonii), black mangrove (Conocarpus erectus), and water zapotón (Pachira aquatica).[1]

Protected areas[]

Officially protected areas in this ecoregion include:

  • , a RAMSAR wetland of international importance.[6]
  • La Encrucijada Biosphere Reserve, UNESCO Biosphere Reserve.
  • , a RAMSAR wetland of international importance.[7]
  • . A Marine Turtle Reserve, and RAMSAR wetland of international importance.[8]
  • . A RAMSAR wetland of international importance.[9]
