Satellite analysis reveals tiger habitats more intact than expected; area large enough to double wild tiger population remains

Key points:

  • Tigers need large areas to survive but if well protected, populations can rebound quickly - Nepal and India experienced 61 and 31 percent increases, respectively, in their tiger populations recently thanks to better habitat protection and anti-poaching efforts.

  • The global tiger population now stands at fewer than 3,500; goal is to double by 2022.
