This chapter is based on my thesis to obtain the Bachelor of Science in Environmental and Resource Management at the Technological University of the Rainforest. I conducted research in three communities of the Lacandon Rainforest with the purpose of understanding vegetation cover changes due to anthropic activities. Data was collected on several field trips. A tree cover analysis using satellite images was conducted to obtain data of the changes in the area reserved for forest use. Findings suggested that Lacanja Chansayab has a greater deforestation area equivalent to 42%, followed by Betel at 41%, and Crucero San Javier (San Javier Junction) at 17% of deforested hectares. The most influential factor appeared to be population size in each zone.Mexico is a very important country because of its still existing natural reserves, taking the 12th place at a global level in forest surface, as well as the 3rd place in Latin America (Del Angel and Mobarak 2001). The study entitled Capital Natural de México, coordinated by Sarukhán (2009) explained that Mexico has a high number and richness of species as well as genetic variability that is distributed through its territory.Mexico also has a forest surface covering an estimated 146,118,323 ha, composed of many types of vegetation. The biggest part is represented by xerophile bushes (with a 41.2%), temperate forests (24.2%), rainforests (22.8%), and other forest vegetation types (11.8%). All these vegetation types are very relevant to Mexico's environmental, economic, and social context (FAO 2005(FAO , 2010.The State of Chiapas is one of the most biologically diverse and owner of a great biological richness. A rich diversity of landscapes have emerged in this state due to its geographical position, altitudinal amplitude, a complex topography, different climates, its physiographic complexity, and its geological and human history (González-Espinosa 2005). The Lacandon Rainforest, located in the State of Chia-E. Chancayun Kin (B)
