Habitat connectivity concerns the ability of animals to:

Occupy the largest available forest patch

Remain within a legally protected boundary

Reproduce at a particular rate each year

Move between places they need within a landscape

Eturnagaram Sanctuary: Sand-Lorry Traffic, Wildlife Movement and the Proposed ESZ

Why in news?

A November report in Deccan Chronicle raises concerns about sand-lorry traffic through Eturnagaram Wildlife Sanctuary in Telangana. Residents described heavy vehicles moving through the forest at all hours, with noise and reported animal deaths on the roads. A district forest official quoted in the report said the final notification for the sanctuary's proposed eco-sensitive zone was still awaited. The issue connects two responsibilities: protecting wildlife within a sanctuary and managing activities in the surrounding landscape.

The sanctuary's setting

Eturnagaram Wildlife Sanctuary is in Mulugu district, in northeastern Telangana. It lies in the Godavari river landscape, near the wider forest region extending towards Chhattisgarh and Maharashtra. Telangana Tourism describes its mixed deciduous forests and its association with the Godavari.

The Ministry of Environment, Forest and Climate Change's 2015 draft notification records a sanctuary area of 806.15 square kilometres. Government tourism accounts date its establishment to 1953. The landscape includes forest, streams and places used by wildlife for feeding, shelter and movement.

In deciduous forests, many trees shed their leaves seasonally. Water availability and vegetation change through the year, influencing where animals find resources. The sanctuary's river and stream setting therefore forms part of its ecological value alongside the forest cover.

How roads affect wildlife movement

A road creates a strip of transport infrastructure through the surrounding habitat. Animals may need to cross it while moving between feeding areas, shelter and water. Vehicles introduce a collision risk at those crossing points.

The Wildlife Institute of India's guidance explains that roads can also act as barriers to movement. The road surface, embankment or passing traffic may make crossing difficult or discourage it. A forest can remain visible on both sides of a road while the connection between those parts becomes harder for animals to use.

This is a question of habitat connectivity: the ability of animals to move through the landscape between places they need. Traffic intensity, vehicle speed and the behaviour of different species influence the barrier and collision effects. Understanding local crossing patterns helps identify where management measures are needed.

The proposed eco-sensitive zone

An eco-sensitive zone, or ESZ, is an area where specified activities are regulated to protect ecological conditions around a protected area. The central Environment Ministry uses the Environment (Protection) Act, 1986, and associated rules for these notifications. A notification identifies the extent, boundaries, activities and management arrangements relevant to that place.

The official Eturnagaram draft is S.O. 2046(E), dated 27 July 2015. It proposed an ESZ of 1,281.7 square kilometres, extending up to ten kilometres from the sanctuary boundary. These figures describe the published proposal. The November report quotes the forest official as saying that the final notification remained awaited.

The draft also envisaged a Zonal Master Plan prepared by the State Government in consultation with local people and relevant departments. Such a plan connects land use, settlements, water bodies, livelihoods and ecological needs within a common planning framework. The 2015 draft explicitly included consultation with departments responsible for forests, revenue, agriculture, irrigation and public works, among others.

Protection within the sanctuary

The sanctuary's legal protection operates under the Wild Life (Protection) Act, 1972. Section 29 regulates destruction, exploitation or removal of wildlife and damage or diversion of wildlife habitat through a statutory permit framework. This protection applies to the sanctuary itself, alongside the separate process for an ESZ around it.

The distinction matters in assessing the reported delay. The pending ESZ concerns the additional framework for the surrounding zone. Questions about activity within the sanctuary also require attention to its existing wildlife protections, the location of the activity and the relevant permissions.

Connecting traffic management with conservation

Official road-and-wildlife guidance identifies measures such as suitable wildlife passages, road signs and speed management, selected for local conditions. These measures work best when planning uses evidence about animal movement and the features of the road. The Deccan Chronicle report also points to a need for coordination between forest, mining and transport authorities.

Conclusion

The Eturnagaram issue concerns how a busy transport route interacts with a living forest landscape. Protecting that landscape requires attention to animal crossings, traffic and authorised activities. Coordinated management connects the sanctuary's legal protection with the practical conditions wildlife encounters on the ground.
