Abstract: A species' risk of extinction is estimated by the deterioration state of the population. A wild and non extinct species could be evaluated and ranked as follows: Critically Endangered, Endangered, Vulnerable, Near Threatened, Of Minor Concern. This ranking has been applied in Colombia for some groups of fauna and flora. Information of the Red Books Series of Threatened Species of Colombia —Libros rojos de especies amenazadas de Colombia— (reptiles, fresh water fish), is used in this paper for estimating the probability change of extintion risk upon changes in economic variables which show some kind of pressure for direct exploitation of habitat change. The quantitative tool for information analysis is a model of ordered discrete dependent variabl
