Abstract: In past years, caiman populations were
utilized without a solid basis of biological knowledge, nor the status of the
populations. Fortunately, this situation has changed, and today, studies are
necessary in order to access to wildlife to undertake a sustainable use program.
In Argentina, it is a requirement for Ranching programs that monitoring of wild populations in each Province be
undertaken; so available information about the status of both caiman species
distributed in Argentina
(Caiman latirostris and C. yacare) have increased. In this work
we present surveys results, done during 2007 in Formosa
and Salta Provinces,
and in 2008 in Corrientes Province,
Argentina. In the
three Provinces, wild populations look healthy, presenting higher densities in Formosa
(up to 144 ind. km-1). In Salta
Province, we found
principally C. latirostris. In Formosa,
results were more variable, existing places with abundant populations of C. latirostris and some others presenting
higher densities of C. yacare. In Corrientes Province,
C. latirostris was found in the
southwest portion, Yacare caiman was found in the northeast of Corrientes Province, and both species share
distribution in the northwest part
