Abstract

Landsat Thematic Mapper (TM) data were used to classify forested areas within the historic distribution of the endangered cotton-top tamarin (Saguinus oedipus) in Colombia. This species continues to be threatened by habitat destruction, and we observed a 31% decrease of the forested habitat within the tamarins' historic distribution in 1990–2000. It is estimated that since the establishment of some protected areas for cotton-top tamarins and other native Colombian wildlife (Parque Nacional Natural Paramillo, Santuarío de Fauna y Flora Los Colorados, and Reserva Forestal de Montes de Maria), almost 43% of the original forested area has been lost. Given that the human population of Colombia increases annually by 1.6% [Patel, 2002], it is important to target specific areas for tamarin protection while creating mitigation strategies to compensate for economic growth. The results of this study provide valuable information to assist in the long-term development of effective conservation strategies for this endangered primate. Am. J.
