In landscapes where wildlife occurs in low densities, gathering information from a single data source often does not permit accurate estimation of population densities and abundance. In such cases, using multiple data sources may allow us to overcome ecological and logistical constraints to estimate densities of elusive carnivores such as tigers. In particular, innovative spatially explicit capture-recapture modeling approaches integrate information from photographic capture-recapture and genetic data to derive more robust estimates of tiger densities in India.
