GONZALEZ SALDIVAR, Fernando N.; CANTU AYALA, Cesar M.; UVALLE SAUCEDA, José I.  and  HERRERA FERNANDEZ, Bernal. Current situation of wildlife in the basins of Nuevo León, Mexico. Rev. mex. de cienc. forestales [online]. 2018, vol.9, n.50, pp.223-250. ISSN 2007-1132.  https://doi.org/10.29298/rmcf.v9i50.265.

The present study was carried out through the analysis of the existing data on the richness of wildlife species, exotic species, endemic species and species at extinction risk according to NOM-059-SEMARNAT-2010, of the 14 hydrographic watershed of the Nuevo León state. To analyze these data, area aptitude indexes can be constructed from basic life history information or modifying existing models, based on the importance of the variables were used, applying normalization, weighting and hierarchization of the values of each of them. The highest positive values watershed were: Tamesí River, Presa San José-Pilares and others and Sierra Madre Oriental (with positive values of 19.65, 18.19 and 16.59 respectively). The highest negative values watershed were: Cuenca Río Bravo-Nuevo Laredo, Cuenca Río Bravo-Sosa and Cuenca Río Bravo-Matamoros-Reynosa (with negative values of -22.07, -20.85 and -19.56). It is concluded that the Sierra Madre Oriental watershed is the most important in Nuevo León for its greater positive value and the territorial extension it covers (almost 13 % of the total state) compared to the first two basins, which together account for barely one percent of the state territory.

Keywords : Biodiversity; conservation; hydrographic watershed; environmental indexes; hierarchy indexes; terrestrial vertebrates.
