Avaliação da estrutura florestal e áreas adjacentes ao corredor ecológico Santa Maria

Abstract

With the fragmentation of forests that covered our entire national territory, ecological corridors have emerged as the main alternative for transposition, transit and genetic exchange among the remaining forest fragments. Understand and study these corridors are of vital importance and in western Paraná one of the most important corridors is the Ecological Corridor Santa Maria, located between the municipalities of Santa Terezinha de Itaipu and São Miguel do Iguaçu Paraná state. The Ecological Corridor Santa Maria links the Iguaçu National Park to PRNP Santa Maria and protected areas of the reservoir of Itaipu Binacional. In the survey objectives were to assess the current composition of the hall and adjacent areas, and the situation in 2003 when the project was implemented. In the study, we obtained a total protected area of 902.06 ha corridor with a length of 13 km; it was found that the area of the hall was totally fragmented in 2003 with 16.6% of its total area to some kind of use; already surroundings with a buffer of 200 meters from the edge of protected areas was reached 68.92% occupied with agriculture, 27.00% with pasture, 2.36% in reforestation, 1.22% with native forest and 0.50% with dams, as well as 25 residences, three aviaries and 14.4 km of roads. This evaluation demonstrated how was the situation at the beginning of the work and how the situation is today in its protected areas or use in your surroundings. This diagnosis is an important tool to support future conservation work that could be realized in the region.
