ORTIZ, Sonia G.; ACOSTA, Juan C.  y  MURUA, Fernando. Fauna of vertebrates and mining activity: base line study in the Castaño river basin, San Juan, Argentina. Multequina [online]. 2003, vol.12, n.1, pp.23-35. ISSN 1852-7329.

The goal of this paper was to make a diagnosis of the composition and conservation status of vertebrates and their habitats in the Castaño River. Vulnerable species and critical areas that show an old mining tradition were defined. The methodology was organized considering: 1) inventory, and 2) evaluation of habitats and conservation status. The 63 vertebrate species found were classified as: 1 fish, 2 frogs, 5 reptiles (4 lizard and 1 snake), 51 birds and 4 mammals. Habitats occupied by fauna were delimited and classified as: a) hydrophytic communities and riparian forest, and b) xerophytic shrub steppe. Each habitat was stratified and active species occupation was estimated. In relation to the conservation status of birds, 37 % shows some problem. Critical areas used by birds, mostly as nesting and rearing places, are suggested.
