strategies for jaguar conservation in northern mexico
Carlos A. López González
Recent sightings of jaguars in Arizona have revived the myth of the species’ persistence in the United States. The nearest population is currently located about 135 miles south of the international border in Sonora, where livestock ranching is the main source of income. The perception of ranch owners there is that jaguars are the main cause of cattle mortality. At the same time, jaguars are important ecological regulators and considered a priority species for conservation by the Mexican government.


Our goal is to reduce jaguar mortalities and increase the probability of jaguar colonization into the United States. We are developing an interdisciplinary approach to jaguar conservation by

• carrying out an ecological study,

• developing a protected area, and

• building community relationships.

Among our activities is the photo-capture of jaguars to monitor habitat use, activity patterns, and interactions with cattle, which will help us understand the factors causing depredation. Livestock will be monitored to determine the causes and frequency of mortality.

We are collaborating with ranchers to incorporate their ideas into a management plan that will ultimately help to conserve the jaguar, while increasing ranch productivity by identifying causes of livestock mortality.
