Healthy Jaguar populations recorded in FSC-certified concessions

A new study by conservationists from San Diego Zoo Global and the Bronx Zoo-based Wildlife Conservation Society (WCS) has found that jaguar populations can thrive in well-managed FSC forests.


The study, titled ‘Do responsibly managed logging concessions adequately protect jaguars and other large and medium-sized mammals? Two case studies from Guatemala and Peru’ published in the April issue of the journal Biological Conservation, was carried out in forest concessions certified to FSC-standards in Guatemala and Peru.

To conduct the study, the research team set up camera traps to measure how effective these concessions are in maintaining healthy populations of land mammals, with a focus on jaguars (Panthera onca), the Western Hemisphere’s largest cat species.

The camera traps in Guatemala’s Maya Biosphere Reserve photographed 23 jaguars, whereas the traps in two Peruvian concessions in the Madre de Dios region recorded 43 individuals. Spot patterns, unique to each animal, were studied to accurately determine ‘recaptures’ of the same jaguar. Calculations based on captures and recaptures in the Guatemala site showed an average of 1.5 jaguars per 100 square kilometres. While in the Peru sites, the average density was 4.5 jaguars per 100 square kilometres.

In addition to the big cats, both sites supported more than 20 large and medium-sized mammal species, with 22 in Guatemala and 27 in Peru.

Deforestation is largely responsible for habitat loss of species that thrive in biodiverse regions of Central and South America, home to jaguars, tapirs, peccaries and other species. Studies such as this one offer an accurate measure of the impact of logging operations on wildlife and how low-impact timber management, as practised in FSC-certified concessions, can be effective in conserving species such as the jaguar, classified as near threatened on the IUCN red list.
