Proposta de recuperação da mata ciliar em um trecho do rio do peixe no município de Aparecida-PB.

Abstract

The removal of riparian forests causes various environmental problems such as soil erosion, siltation of waterways, loss of fauna and flora, water shortages in certain regions, intensifying the greenhouse effect and climate change. According to Brazilian environmental legislation, riparian forests should be preserved and restored - if they are degraded - in compliance the minimum marginal strips according the channel width of waterways. Based on this context, in this work aims to develop a recovery proposal for a fragment of riparian forest in Peixe river in the municipality of Aparecida-PB. A methodology used was based on bibliographical research, informal interviews with local residents, photo documentation, field visits, floristic inventory and the use of satellite images, software of geoprocessing tools and methods of Environmental Impact Assessment (EIA): "Ad Hoc" and "Check Lists". According to the results, 16 environmental impacts were identified in the study area, wherein 10 were "significant" and 06 "not significant". It was also observed that the environmental components most affected by various types of degradation were: water, fauna and flora. To recover the area were indicated the following recovery techniques: isolation of the area, soil amendment, revegetation and cultural treatments. Finally, it was indicated an environmental monitoring plan to prevent the return of the degrading agents and contribute to the efficiency of the techniques chosen for recovery.
