Mangroves

Mangroves are flooded forests distributed in coastal areas of tropical climates where salty sea water merges with fresh river water: they cover the banks of lagoons, estuaries, rivers, deltas, marshes, etc.
These ecosystems are characterized by their adaptation to salinity. More...

Stockbreeding is one of the most important causes of mangroves destruction.

Nowadays, mangroves are seriously threatened ecosystems.

Year by year more than 8,400 hectares are destroyed in Mexico, which implies a lack of appreciation of their environmental services and a lack of effective protection.

The main causes of their degradation in Mexico are the expansion of infrastructure for tourism, ports and industry .

In Veracruz, the strongest threats are from cattle ranching, port infrastructure development, road construction, oil exploration, fire and illegal logging.

Illegal logging in mangrove.

Apparently the actions of legal protection and for conservation and restoration have not been sufficient to halt the decline of the mangroves.

In 2011 fly-over, in Alvarado, Veracruz, we documented fires that affected hundreds of hectares of mangroves. These fires were made possible when cattle ranchers drained the mangrove swamp. The channels that furnish it with water have been lined with levees, disrupting the ebb and flow of water to these forests.

Thousands of hectares of mangroves were devastated by fires in 2011.

Particularly in the area of the Alvarado Lagoon System (lower Papaloapan), the activities of greatest impact are the expansion of sugar cane cultivation and grazing (see map "Location of the study area").

For the period from 1976 to 2000, INEGI data show severe destruction of mangroves and other wetlands. During this period, 4.000 hectares were destroyed, an average of 250 per year (see map "Change of Land Use").

Since 1998 we have adressed the mangrove issue by:

Developing effective ecological restoration techniques for mangrove forests.

Generating useful geographical and ecological data for restoration.

Raising mangrove trees for reforestation (UMA MX-VIV-CO-296-VER/11).

Create visual informative materials to raise awareness about the importance of wetlands and promote citizen involvement

• Generate information about the botanical origin of mangroves honey.

YOU can support us by sponsoring a mangrove tree.

The Alvarado lagoon system (or Papaloapan River Wetlands) is located in the central-southern part of the state of Veracruz, covering 315,494 hectares. Their catchment areas are in the mountainous areas of Oaxaca, Puebla and Veracruz (see location map).

The area is composed of a wide range of environments with 29,391 hectares of lagoons, 19,826 hectares of bulrush and 17,858 hectares of mangroves.

All these environments together constitute the habitat of many species, among which are migratory and resident birds and fish and crustaceans of commercial importance.
