Study: Restoring & maintaining corridors between PAs significantly cuts tiger extinction risk

Changes in future land use, increased fragmentation of tiger habitat and the inevitable loss in genetic diversity puts tiger populations at small and isolated reserves at high risk of extinction. Unplanned development can increase the probability of extinction by over 50%, a recent study has found.


The study, Maintaining Tiger Connectivity and Minimising Extinction into the Next Century: Insights from Landscape Genetics and Spatially-Explicit Simulations, published in the February 2018 issue of the Biological Conservation journal, examined the population connectivity of tigers across nine reserves, and used genetic data to infer the impact of changing landscapes on the species and simulate their extinction probability in different scenarios.
