CHAPTER 2Forest Cover and ProtectionThis chapter evaluates the state of knowledge regarding the nation’s forests and the degree of protectionprovided by existing protected areas. To determine the status of Venezuela’s forests, we analyzedavailable information on forest cover and protected areas. Specifically, we sought to answerthe following questions:• Where are Venezuela’s forests and how has forest cover changedover the last decades?•What is the status of protected areas in Venezuela’s forestsand in the Guayana region specifically?•How have protected areas been managed in Venezuela?To answer these questions, we used government maps of protected areas, a regional map of forestcover developed by the Tropical Ecosystem Environment Observations by Satellites Project(TREES), derived from the use of the NOAA Advanced Very High Resolution Radiometer (AVHRR)sensor, and a national vegetation map published in the mid-1980s. We compared these map data tostatistics released by the Food and Agriculture Organization (FAO) for national deforestation. Theseresults reveal significant inconsistencies between datasets, and raise questions about the reliabilityof current forest cover estimates.We encountered several difficulties in analyzing the protection status of forest cover, due to the lackof a georeferenced map of protected areas and an official map of political boundaries. Schematicmaps available from government offices have technical deficiencies resulting from the fact that protectedareas are mapped individually and then transferred onto a national scale map using outdatedcartographic methods and inaccurate base maps. Until 1998, presidential decrees establishing protectedareas did not require prior technical consultation with the official cartographic office(Instituto Geográfico de Venezuela “Simón Bolívar”), which resulted in cartographic errors in delineatingthe boundaries of these areas. We also encountered difficulties mapping the large number ofestablished protected areas (362 total) because of overlap between protected area boundaries; theextent of overlap suggests a lack of information and poor coordination on the part of governmentofficials when delineating protected areas.11
