  General Description   Tacaná Volcano, shared in the borderline with Guatemala, is part of the Central American Core (Nucleo Centroamericano) volcanic chain. It contains fragile ecosystems very rich in wild flora and fauna species of cultural, scientific, economic and biological relevance. Its rich biodiversity and high endemism are found particularly in the high mountain ecosystem and landscapes and in the volcanic edifice which presents geophysical features of great scientific and aesthetic value, representative of humid environments of Andean origin that are found in Mexico.
Nowhere else in the Pacific Coast of Mexico or in Central America except for Guatemala precipitations reach 2000 mm to 5000 mm per year, as in the Soconusco. The result is that only in this area of the vast Mexican slope of the Pacific are there dense and high rainforests which could be compared to the ones found in the most humid regions in the Atlantic Ocean. The main types of ecosystems found in the Tacaná Vocano area are terrestrial and they are represented basically by: Middle evergreen forests, hard and flat leaves forests (oak), forests of acicular or scale-like leaves (pines) and high moors which is characteristic and unique in Chiapas and in the country. There are aquatic ecosystems in the region, from which we highlight the Coatan River and the Suchiate River because they have permanent affluents.
Regarding socio-cultural aspects, the last Mexican population of the indigenous group Mame are found in the Reserve, in the high zones of the municipalities of Unión Juárez, Cacahoatán and Tapachula, who still keep their language and traditions. In the region, the Ireland farm is where organic coffee production started for the first time in Mexico. In the communities located particularly in the Sierra Madre of Chiapas, a new opportunity for development is emerging with the implementation of alternative plantations, such as organic coffee. Moreover, Chiapas is the main organic coffee-producing region in the world*. This has been combined with the application of good practices for farming and extraction of natural resources; such strategy has helped producers to reach other supportive markets that acknowledge the protection of natural resources. This is no exception in the Tacaná, since there are crops in the transition zone, such as cacao and coffee, corn, natural pastures and fruit trees. Through investment and training in good practices, the management of coffee and cacao plantations may become model activities of sustainable development by allowing producers the access to fair markets as for example the market of organic products.
