Fragmentation of Central Indian Forest Corridors: Implications for Tiger Conservation and Genetic Diversity
GS3GS1GS2
A recent ecological study warns that shrinking forest corridors in Central India are obstructing the natural dispersal of tigers between protected areas. This fragmentation threatens genetic health and increases human-wildlife conflict, highlighting the need for wildlife-sensitive infrastructure planning.
Central India, often referred to as the 'tiger heartland,' is home to a significant portion of the world’s wild tiger population. However, a recent study has raised alarms regarding the increasing fragmentation of forest corridors that connect major Tiger Reserves like Kanha, Pench, and Bandhavgarh. These corridors are essential for the natural dispersal of sub-adult tigers seeking new territories and mates, ensuring genetic flow across the landscape.
The study identifies linear infrastructure—such as highways, railway lines, and irrigation canals—along with changing land-use patterns as the primary drivers of this fragmentation. When these natural pathways are severed, tiger populations become 'islands' of genetic isolation. Over time, inbreeding can lead to reduced fitness and increased vulnerability to diseases, potentially resulting in local extinctions. Furthermore, as tigers find their traditional routes blocked, they are more likely to wander into human-dominated landscapes, significantly escalating the frequency and intensity of human-wildlife conflict.
