Northern Jaguar Reserve and cattle ranches near the reserve. The reserve is private land without cattle. Since 2007, cattle ranches have been enrolled in an agreement for jaguar and other feline protection in the eastern part of Sonora, Mexico.

Changes in study area from 2000 to 2012.
The extension of the study area is due to ranchers’ permission for monitoring in the area and camera availability. Darker areas correspond to land purchased for the reserve creation and light polygons correspond to cattle ranches. A) study area in 2000, B) study area from 2001 to 2002, C) study area from 2003 to 2006, D) study area from 2007, E) study area from 2008 to 2010, F) study area from 2010 to 2012.

Female jaguar and her cub photographed in February 2011 at the reserve.
The female (JH-12) stayed in the area for almost two years. The cub (JNI-18) was never detected again. Juveniles were not included in the study because of their low capture probability. Photo credit: Northern Jaguar Project/Naturalia A.C.
