ARREDONDO LEON, Carlos. State and forest landscape dynamics in Cherán Municipality, Sierra Tarasca, Michoacán. Rev. mex. de cienc. forestales [online]. 2017, vol.8, n.39, pp.7-24. ISSN 2007-1132.

The work described here analyzes the state and dynamics of the forest landscape in the Cherán municipality located in the central part of the Meseta Purépecha region of Michoacán State. The spatial configuration and transformation of the landscape is due to both natural and socio-cultural factors; from this perspective, takes a leading role as the synthesizing element of anthropic intervention on the natural physical environment. The description was based on a photographic inventory and the landscape dynamics in georeferenced spatial information in a GIS that is obtained from the interpretation of aerial photographs and Landsat satellite images. The resulting maps were subjected to a statistical analysis to calculate the surfaces, Deforestation Indices (r) and Annual Average Transformation (ITMA) to evaluate the magnitude of the change in the area covered by forest. Results indicate that the current state is subordinated, inter alia, to the geographical situation of the municipalities in the region and the communication channels, while the dynamics, in terms of land use, has been characterized by a long history of deterioration that, in the last three decades, has been reduced by the effects of abandonment with the consequent expansion of the forest area. The results indicate that the state of forest landscape is subject, among other things, to the regional geographical situation of the municipalities, while the landscape dynamics -in terms of the land uses- has been characterized by a long history of deterioration that has been diminished in the past three decades due to the abandonment of the land use, so the forest area has been gradually expanded.
