Abstract
Natural ecosystems are renewable resources with special environmental, social and economical attributes and characteristics. The increasing need of the human beings for a better environment leads to the use of new technologies that offer many advantages in detecting changes in the ecosystems. In this study the integration of remote sensing tools and technology and the spatial orientation analysis of Geographical Information Systems (G.I.S.) combined with in situ observations were used in determining any changes in land cover categories along an 18 year period. The study area of 9,287 ha extends to Pindus mountain, in the municipality of Plastira, central Greece. The results have shown that the current technologies can be used for the modelling of environmental parameters improving our knowledge on its attributes, characteristics, situation, trends and changes of natural ecosystems. The multitemporal changes that were observed are mostly due to vegetation evolution and less to socioeconomic reasons. The basic management strategy for the specific area should combine forest, pasture and livestock in such a way that each component produces usable products, while in the same time preserves sustainability.
