Jaguar Long Term Monitoring Program in the Pantanal, MS

Since 2002, this project has focused on jaguar population dynamics in the Pantanal, Mato Grosso do Sul State, studying the ecology, epidemiology and demography of the species within privately-owned properties.

The Jaguar Project started in September 2002 in the Pantanal, is currently developing partnerships with rural land owners in Aquidauana, Miranda, Rio Negro and Nhecolândia in the Pantanal. The total area of the project involves approximately 280,514 hectares (693,165 acres) of natural habitat for jaguars. The research headquarters of the project are located at the Caiman Ecological Refuge, in Miranda – Mato Grosso do Sul State.

The main objective of the project is to develop a model for jaguar conservation within private properties in the Pantanal. Demographic and ecological data are being collected through camera traps, direct observation, scat detector dogs, and radio-telemetry. To date, 22 jaguars have been captured and fitted with radio-collars. Biological samples were collected from jaguars to inform genetic and epidemiologic analyses. Through radio-telemetry techniques, the jaguar’s home range was estimated to be 21 km² for females and 58 km² for males. Through monitoring activities, it was determined that the cubs follow their mother for one and a half years, and after that they establish their own territory. Since November 2008, a female jaguar has been monitored in the Barranco Alto Farm in the Pantanal of Rio Negro. This is the first jaguar study in this region.

Through camera traps, 60 jaguar pictures have been obtained and 36 individuals have been identified in the area. The project aims to monitor the jaguar population in the region, identifying possible population trends (growth, stability, decrease) over a number of years, an important aspect in understanding the conservation status of the species.
