Descripción
The
conservation status of the fauna of amphibians and reptiles of the Nahuel Huapi
National Park and Reserve is evaluated in the present work. Fourteen species of
amphibians and 11 of reptiles in the study area were considered in the
methodology which consists in assessing the degree of conservation of each
species through an index made up by 12 survival-related variables (Reca el al.
1994). A list of species ordered according to their conservation indices for
Argentina was obtained. The addition of two variables accounting for the
particular situation of the species within the study area, allowed the
elaboration of another list showing the conservation requirements for the Park
and Reserve. Both ordinations are similar. The species in most critical conservation
situation are the amphibians Atelognathus nitoi, Batrachyla antartandica,
Rhinoderma darwinii, Alsodes gargola, Eupsophus roseus and A. verrucosus and
the reptil Tachymenis chilensis. The variables of the greatest influence upon
the value of the index are those related to distribution, habitat use and
trophic amplitude. The results were compared with conservation evaluations of
the same species made by other researchers and institutions. Differences and
similitudes between evaluations were detected. Both the index value and its
component variables provide an useful tool in making decisions for conservation
and management.
