Disturbances from road affect wildlife: Study.

Content

Road-related disturbances can influence presence of species in adjacent forest areas, a study by Wildlife Institute of India (WII), Dehradun, has found.

The study titled ‘Road effect zones of major prey species in roaded landscapes in India’ is part of a larger road ecology research project being conducted by WII. The results were presented by senior research fellow with the project Akanksha Saxena at the annual research seminar at WII recently.

The research project aims to assess ecological impact of roads on wildlife and is based in three important landscapes — Kaziranga-Karbi Anglong (Assam), Nagarhole-Bandipur (Karnataka), and Central India (Maharashtra & Madhya Pradesh) tiger corridors including roads around Navegaon-Nagzira, Tadoba and Kanha-Pench tiger reserves.

According to the study carried out on road segments passing through forests, roads can reduce chance of some species inhabiting forest areas up to 500 metres from the road, an area that is ecologically called ‘road-effect zone’.

Commentary

The presence of roads near or in wildlife habitat has en effect on wildlife, shows a study in India.

The effects vary, from species inhabiting (or not) forest areas near roads to the total absence of e.i. prey of tigers (like sambar deer and chital).
