Resumen:
Programs using wildlife should have a monitoring
system so if necessary correction action could be done in order to maintain
sustainability. In Argentina ranching programs need to have a monitoring of the
populations under management, in this work we present spotlight surveys carried out in Corrientes province
for six years (between 2008 to 2013), we selected representative locations
1. inside IBERA RESERVE, 2. in
PRIVATE LAND were no management occurs, and 3. sites were YACARE PORA
harvests caiman nests. We used the highest relative density (RD) of every place
for a certain year in order to calculate mean RD for every one of the three
management options described. We did not find any clear trend for populations,
besides that RD seem to change in a regional scale producing peaks for every
management option in the same years. IBERA RESERVE populations show the highest
variation in RD over time, possibly related to the high surface of floating
vegetation in the area. Nest harvesting and reintroduction of yearlings is not
affecting population trend.
