A significant finding of a jaguar specimen has been documented in the Río Pilcomayo National Park.
They recorded a new jaguar specimen, provisionally identified as MACHO10 (M10). This individual represents the second jaguar photographed within the boundaries of the National Park and the tenth in the entire vast ecoregion of the humid Chaco.
The monitoring of the jaguar specimen in the Río Pilcomayo National Park is part of a sustained and collaborative effort being actively deployed throughout the Chaco region.
This program integrates the dedicated work of park rangers, technicians, researchers, local inhabitants, and other collaborators, all united by a strong commitment to the conservation of this emblematic species.
Since March 2024, when fresh tracks of the species were detected in the protected area, the strategic installation of trap cameras was carried out.
The objective of this action was to confirm the presence of the feline and, crucially, obtain precise information about its health status, sex, and movement patterns, indispensable data to strengthen existing conservation strategies.
How was the jaguar specimen recorded?
In this context of intensive monitoring, trap cameras recently captured images of a new jaguar specimen.
As mentioned, it is the second individual registered within the Río Pilcomayo National Park and the tenth in the Chaco region as a whole.
This individual, provisionally named MACHO10 (M10), is a male in excellent health and had not been documented previously. Its identification was possible thanks to the unique pattern of its spots, which functions as an individual fingerprint.
This important achievement reflects the positive impact of the joint work being carried out in the region between the Jaguar Project (CeIBA-CONICET), the Río Pilcomayo National Park itself, and the NEA Regional Conservation Directorate (APN), all with the valuable support of the Wildlife Conservation Foundation of Argentina.
This collaborative effort not only strengthens monitoring and research strategies, but also ensures long-term protection of the habitat of the jaguar against increasing threats to biodiversity.
It also emphasizes the fundamental importance of protected areas for the survival of this severely threatened species.
The registration of this new jaguar specimen is great news for the population of the species, which has been declared a National Natural Monument.
This discovery reinforces the ecological value of the Río Pilcomayo National Park as a vital refuge for key species like the jaguar.
Likewise, it represents hopeful news for the vast region of the Gran Chaco, where current estimates suggest that there are just under 20 individuals of this species remaining.
Why is the conservation of the jaguar crucial?
The jaguar (Panthera onca) holds the title of being the largest feline in the American continent and the third globally, surpassed only by the Asian tiger and the lion.
In Argentina, this species is in a situation of critical danger of extinction.
The main causes of this vulnerability are the alarming loss and fragmentation of its natural habitat, roadkill, and illegal hunting, both of the feline itself and its prey.
As the top predator within its ecosystem, a jaguar specimen plays a fundamental ecological role. Its presence is vital for regulating the populations of other vertebrates, particularly the large herbivores.
Therefore, the existence of the jaguar in a habitat is an excellent indicator of the health and balance of the ecosystems in which it lives.
It is estimated that in our country, the jaguar population is scarce, with less than 250 individuals in total. Of these, it is believed that less than 20 are specifically distributed in the Chaco region, covering the provinces of Chaco, Corrientes, Formosa, Salta, and Santiago del Estero.
The jaguar is legally protected by being declared a Provincial Natural Monument (Law 1,673) and National Natural Monument (Law 25,463). Consequently, its hunting is strictly prohibited.
The categorization by the Argentine Society for the Study of Mammals (SAREM) in the Red Book of Endangered Mammals of Argentina classifies it as critically endangered at the national level.
