|Biosphere Reserve Information|
The Reserve is an area of high geological and ecological complexity and of human activity. It presents a high diversity of environments that correspond to nine types of vegetation. It is of great relevance as it is the North limit of the rainforest in the American continent and a unique case in Mexico and North America, given the connection of different types of forests and rainforests, from the sea coast to the summit of the volcanoes. It constitutes a source of rainwater harvesting for being one of the rainiest areas of the country.
Since it is a mountain of volcanic origin, it presents an abrupt topography of difficult access for productive activities. The different geology and volcanological history occurred in each one of the three great volcanoes, had as consequence the floristic differentiation in the forestal cover of each volcano, forming a heterogeneous mosaic of forests and rainforests particular to each volcano.
In the mountain Los Tuxtlas and its surroundings, eight different climatic subtypes are represented, six subtypes of warm climate, one semi-warm and one temperate. According to Köppen’s climate classification, modified by García (1964), the subtypes warm-humid are the most extended in the area (subtypes Af and Am).
In the region of Los Tuxtlas were some of the first urban settlements of Mesoamerica and the continent. Different phases of the Olmeca culture were developed in this zone. Currently in the area we can find indigenous groups (popolucas and nahuas) that maintain a great part of their cultural features. The zone is a mosaic of ethnic groups: indigenous mestizos and natives of different European origin.
|Major ecosystem type||The Tuxtlas Biosphere Reseve presents a high diversity of environments and types of vegetation. Nine types of primary vegetation have been identified in it, However, the predominant forest in the reserve is the evergreen forest.|
|Major habitats & land cover types||Within the reserve we can identify nine types of vegetation, highlighting the evergreen forest due to its extension, followed by the mountain mesophyllic forest; added to other types of habitats, such as mangrove and coastal dunes.|
