Building bridges in the forest, to help wildlife:


Context:

Ramnagar Forest Division in Nainital district, Uttarakhand, recently built its first eco-bridge for reptiles and smaller mammals.

Examples of eco-bridges:

These include canopy bridges (usually for monkeys, squirrels and other arboreal species); concrete underpasses or overpass tunnels or viaducts (usually for larger animals); and amphibian tunnels or culverts. Usually these bridges are overlaid with planting from the area to give it a contiguous look with the landscape.

Why eco-bridges matter?

They enhance wildlife connectivity that can be disrupted because of highways or logging.

Many road projects cut across animal corridors. For example, National Highway 37 through the Kaziranga-Karbi Anglong landscape in Assam, and State Highway 33 through the Nagarhole Tiger Reserve in Karnataka.
