Research overview: tiger reintroduction at Panna and Sariska

After poaching wiped out tigers in two Indian reserves, Sariska and Panna, conservationists attempted to rebuild populations by translocating wild tigers from source reserves. This overview surveys the science and outcomes of those efforts, which involved capturing, relocating, and intensively monitoring founder animals via radio-collars. Panna in particular saw breeding females re-establish and the population grow, demonstrating that reintroduction can restore locally extinct tiger populations when underlying threats are addressed. Researchers studied founder behavior, ranging, breeding success, and the management changes, including strengthened protection and accountability, needed to prevent a repeat collapse. The cases offer hard lessons about why the original populations were lost and about the demographic and genetic considerations in sourcing founders. They remain key references for planning large-carnivore reintroductions into formerly occupied habitat.
