The Elephant in the Room: Methods, Challenges and Concerns in the Monitoring of Asian Elephant Populations

Increasing anthropogenic pressures has led to the fragmentation of Asian elephant habitats, affecting their numbers, demography and ranging patterns across their range. Baseline information on the demography and population dynamics of free-ranging Asian elephants is often unavailable. Population monitoring at the landscape level has many constraints, including those of visibility, habitat, terrain and field logistics, among several others. While knowing elephant numbers may be important for managing local populations, demographic parameters and distribution patterns are perhaps more crucial to ascertain long-term trends for conservation.
