Research overview: jaguar density networks and range-wide monitoring

Jaguars are monitored across the Americas through camera-trap capture-recapture, and coordinated initiatives increasingly link local surveys into range-wide networks producing comparable density estimates. This overview surveys the growth of jaguar camera-trapping from pioneering site studies to standardized regional monitoring, the application of spatially explicit capture-recapture, and the design lessons learned about array size relative to jaguar home ranges. It discusses identification from rosette patterns, the challenges of low densities and wide ranging, and efforts to harmonize methods so estimates can be compared and aggregated for conservation planning along the jaguar corridor. The overview highlights how networked monitoring supports range-wide strategies, tracks population trends, and identifies strongholds and connectivity needs, demonstrating the value of standardized camera-trap protocols for conserving a wide-ranging apex felid across many countries and habitats.
