BUILDING BRIDGES IN THE FOREST, TO HELP WILDLIFE
Ramnagar Forest Division in Nainital district, Uttarakhand, recently built its first eco-bridge for reptiles and smaller mammals
Eco-ducts or eco-bridges aim to enhance wildlife connectivity that can be disrupted because of highways or logging.
There are two important aspects of building eco-bridges – size and location.
The span and distribution of eco-bridges should depend on animal movement patterns.
The bigger bridges will see sambar, spotted deer, nilgai, wild pig using them, while for tigers or leopards, if the bridge is 5m or 500 m, it doesn’t bother them.
Some animals like the barking deer, which prefer closed habitats, need smaller bridges.
