Análisis del estado de los valores objeto de conservación de filtro grueso (biomas) en las áreas continentales de Parques Nacionales Naturales de Colombia (periodos 2002–2007–2012)

Abstract

This paper analyzes the condition of the Conservation Values Object (CVO) coarse filter on biomes in continental National Natural Parks (NNP) by analyzing State-Pressure-Response (SPR) on the biomes in 2002, 2007 and 2012. Map land cover for these years obtained through satellite imagery and adapted to the legend of Corine Land Cover (CLC) adapted for Colombia was used. Identifying existing biomes at each park for those years, taking into account the natural state or the pressure. Not applicable analyzes (NA) references to cloudy areas where no information of landcover was obtained. The results show that the biomes most affected inpercentage (%) of pressure during the decade are semi arid andean vegetation (22.07%) and andean wetlands lake areas (20.09%), tropical dry scrub (17.62%), tropical dry forests (16.21%) and high andean dry vegetation (9.07%). By the other hand, andean glaciers, bogs andean, amazonian sheets- sheets and shrubs tropical catinga maintained their natural biomes 100%. The rest of the 20 biomes presented in inland areas of the national natural parks had pressures ranging from 0.23% to 5.29%. The analysis of the three periods from land cover determined that the parks that have preserved the natural state of their biomes are SFF Orito Ingi ande medicinal plants and PNN Uramba Malaga bay; while the park presented greater loss of its natural state was SFF Los colorados with a pressure of 26,29 % for 2012.
