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.
