Forest Biodiversity Indicators in the Colombian Andes Track: Ecology and Conservation Author(s): Nelly Rodriguez, Dolors Armenteras, Sonia Sua, Monica Morales, Alexander Rincon The northern Andean montane tropical forests in Colombia are currently one of the major global conservation priorities due to not only their biological richness and high levels endemism but also because they are being subject to high levels of human pressure. Some estimates suggest that only 25 percent of the original forest extent remains, however current deforestation rates figures do not yet exist. Monitoring strategies are essential for determining changes or trends in forests ecosystems and in external factors that might influence them. Humboldt Institute has developed a methodology for mapping ecosystems that is currently being applied in the Andes. This methodology involves repeated measurements over time of vegetation cover variables based on remote sensing and GIS. Indicators of ecosystem condition were derived at the landscape level and we analyzed forest condition indicators such as forest cover, fragmentation, ecosystem diversity, and representativeness of protected natural areas.
