CAVALLARO, Sandra; NICOSIA BURGOS, Federico  and  FONTANETO, Patricio Julián. The environmental cartography as a basis for the ecological territorial planning studies. Rev. Asoc. Geol. Argent. [online]. 2010, vol.66, n.4, pp.475-483. ISSN 0004-4822.

The economic development and population increase produce not only a constant territory demand but also a growing pressure on biophysics environment. Facing the challenge of regional planning, the issue of environmental thematic cartography turns into a fundamental tool to achieve the objectives of sustainable development, integrating biophysical and social information. On other hand, the ecological territory planification allows us to identify the land use and the territory tendencies. This methodology involves the natural resources analysis and its actual status. This information provides the alternatives to establish different land uses to promote sustainable improvement of natural resources. The methodological analysis of ecological land planning integrates the stages of characterization and diagnoses stages with the aim of define different land planning and management proposal. The studied area, that includes the Geologic Leaf 4769-II, shows a population increase and economical development which includes oil exploitation and cattle production. This area requires urgent ecological planning studies to guarantee a balanced and sustainable development. The present paper, that uses information elaborated and compiled in the Carta Geoambiental de la Hoja Colonia Las Heras, scale 1:250000, is elaborated using landscape ecology concepts. Through the results achieved not only the distribution of the vegetation communities and their associated fauna but also their close relationship with the prevailing geomorphologic formations becomes evident. Both the satellite analysis as the campaign checkup confirm the rising fragmentation checkup confirm permanent decline of the animal habitats with the subsequent retraction of the communities.
