Resumen

AGUIRRE GUTIERREZ, Jesús  y  DUIVENVOORDEN, Joost F.. Can we expect to protect threatened species in protected areas? A case study of the genus Pinus in Mexico. Rev. Mex. Biodiv. [online]. 2010, vol.81, n.3, pp. 875-882. ISSN 1870-3453.

The distribution of 56 Pinus species in Mexico was modelled with MAXENT. The pine species were classified as threatened according to IUCN criteria. Our aim was to ascertain whether or not threatened pine species were adequately represented in protected areas. Almost 70% of the species had less than 10% of their modelled distribution area protected. None of the pine species reached their representation targets. Threatened pine species were less widely distributed, occurred at lower maximum elevations, and were less well represented in protected areas than other pine species. The results suggest that the present system of protected areas in Mexico fails to protect pine species adequately. Conservation targets should be especially directed to species with narrow distributions which occur at low altitudes, such as Pinus. attenuata, P. cembroides subsP. cembroides var. lagunae, P. radiata var. binata, P. rzedowskii, and P. muricata.
