What is it about?

Jaguars are critically endangered in Argentina and Yungas ecoregion is an important region for their conservation. This is the first quantitative density estimations for a portion of Argentinean Yungas in an area that is in part protected and used various human activities.

Why is it important?

Abundance estimations are an essential attribute in population biology, necessary for management and conservation planning as well as to assess conservation status. This study represents the first jaguar statistical density estimation for the Yungas region.


This work has two sides, on one this is the first estimation of density for the area, being also more significant because it was not performed in a pristine protected area. Instead of that part of the surveyed land is a protected area (Baritu National Park) and another part was used by human activities such as cattle raising, wood harvest, corps, etc. This estimations contributes to the understanding of critically endangered jaguars. An the other side, more methodological shows the growing of statistical tools can help us to make the most of our data, in our case allowing us to make an estimation despite the high rate of camera malfunction.
