Abstract - IUCN Red List of Ecosystems
Red List of Terrestrial Ecosystems of Costa Rica: Final Project Report Herrera-F Bernal. (2015). Director Cátedra Latinoamericana de Áreas Protegidas y Corredores Biológicos “Kenton Miller”. CATIE, Turrialba, Costa Rica. Abstract: Costa Rica is a country of 51,000 km2 with approximately 5% of the known biodiversity of the world. It presents a large diversity of ecosystems due to its high variability of biophysical conditions. In 2013-2014, CATIE carried out a national assessment of the collapse risk of ecosystems. Phytogeographic units of Zamora (2006) were used and updated for this project. Data of vegetation coverage in 1960 were used, and reviewed and adapted using aerial photographs of the same year. The map of forest coverage of 2010 was also used for the assessment, which was classified from 30m resolution LandsatETM images de 30m. A map of national threats was additionally prepared, which was used as supplementary data according to the criteria of the IUCN Red List of Ecosystems. Criteria A1, B1, and B2 were applied. Other criteria were not applied due to lack of data for their estimation. From a total of 41 assessed ecosystems, 16 were classified as threatened, which represents 39% of the total of ecosystems. Nine out of the sixteen threatened ecosystems are “critically endangered”, three “endangered”, and four “vulnerable”. These results are relevant because they represent information that allows to determine and complement priorities of conservation of the biodiversity in the frame of the efforts of the country to accomplish the Aichi goals established by the Convention of Biodiversity.
