Resumen:
Abstract. In the past, caiman populations were
utilized without a solid foundation of knowledge on the biology or status of
the populations.Fortunately, this situation has changed, and today, detailed studies
are conducted to provide data to underpin sustainable use programs. In
Argentina, it is a requirement for ranching programs that monitoring of wild
populations in each Province be undertaken. Here, we present results of surveys
carried out in 2007 in Formosa and Salta Provinces, and in 2008 in Corrientes
Province. In the three Provinces, wild populations appear healthy, with higher
densities in Formosa Province (up to 144 ind.km-1). In Salta Province, we found
principally C. latirostris. In Formosa Province, results were more variable,
with locations with abundant populations of C. latirostris and some others with
higher densities of C. yacare. In Corrientes Province, C. latirostris was found
in the southwest, C. yacare in the northeast, and both species were distributed
in the northwest. The surveys indicate higher densities of both C. latirostris
and C. yacare than reported in 1991/92 and 1999/2000.
