ACRECHE, N.; NUNEZ, H.A.  and  ALBEZA, M.V.. Vulnerabilidad de la avifauna en el Parque Nacional Los Cardones, Salta, Argentina. Rev. biol. trop [online]. 1998, vol.46, n.3, pp.811-816. ISSN 0034-7744.

Avian vulnerability was studied in three habitats of the National Park Los Cardones (Salta, Argentina): Valle Encantado, Valle Tin Tin and Laguna Cachipampa. These habitats differ in plant abundance and composition, altitude and climate. Vulnerability of avian species was estimated taking into account an index built considering geographic distribution, abundance and habitat specificity. It varies between a maximal of one and a minimal of eight. 40 % of species have the higher vulnerability index (restricted geographic distribution, restricted habitat specificity and low abundance).
