![]() ![]() ![]() Loss of suitable habitat is mainly due to recent expansion in agricultural and livestock production. However, suitable boa habitat has been reduced by one third to approximately 30 million ha from a historical extent of occurrence of about 42 million ha in the Dry Chaco ecoregion. We conclude that CITES has been very effective in stopping the international trade and almost completely eliminating hunting pressure on this snake throughout Argentina. Using a rapid assessment of woody vegetation cover, we estimated the degree of habitat loss in Argentina. We carried out 573 interviews with local residents regarding the historical presence of the species and the ways in which it was used. We evaluated the historical range on the basis of museum and literature records, and later adjusted it to incorporate environmental variables. We compiled background information on trade, biology, and distribution. Twenty years after the species was listed in CITES Appendix I, we carried out a comprehensive review of the conservation status of the Argentine Boa Constrictor (Boa constrictor occidentalis) in Argentina. ![]()
