Conservation India carried a photograph on 9th November 2016 of a tigress making a wild pig kill in Nagarahole. All tigers have stripes that are unique, just like human finger prints. To identify this tigress and trace its history, a WCS team of researchers working under my guidance rapidly matched patterns of this tigress against 850 other wild tigers, whose images are in our long-term camera trap database, maintained as part of a long-term monitoring of tiger populations in the … Read More
Mammals in the Jeypore-Dehing forests, Assam
The Jeypore-Dehing Landscape is located in eastern or Upper Assam. It comprises three large blocks of forest (Jeypore, Upper Dehing West Block and Upper Dehing East Block) and several forest fragments. The reserve forests lie within a mosaic of oil and coal mining grants, tea plantations, agriculture and settlements. The forest type is lowland Assam Valley Tropical Wet Evergreen forest (Dipterocarpus-Mesua) and together stretch over roughly 600 sq km. The landscape is part of the Dehing-Patkai Elephant Reserve and 111 … Read More
Large Trees are Critical for Conserving Woodpecker Abundance and Diversity in Sub-Himalayan Forests
Study: Habitat determinants of woodpecker abundance and species richness in sub-Himalayan dipterocarp forests of northwest India.
Authors: Raman Kumar, Ghazala Shahabuddin & Ajith Kumar Journal: Acta Ornithologica 49: 243-256. Published 2014.
Summary
Birds are highly sensitive to changes in habitat caused by human activity. Habitat change may be manifested in the structural elements of habitat (such as density and size of both live and dead trees), or its composition (i.e. tree species profile), which may translate into alteration in quality … Read More
Large Carnivores in Human Dominated Landscapes
The conservation of large carnivores like wolves, bears, tigers and lions is always a challenging task in our modern and crowded world. Humans have modified and fragmented habitats and often experience a diversity of conflicts with large predatory neighbours. There is currently a major debate going on among conservationists about how to best go about achieving large carnivore conservation. Alternatives range from a focus on fencing carnivores into protected areas to allowing them to reoccupy shared landscapes where they must … Read More
Understanding the Distribution and Occurrence of India’s Smallest Bovid: The Chousingha
Endemic to the Indian sub-continent, the four-horned antelope (FHA) or Chousingha is listed as Vulnerable (C2a (i)) in the IUCN Red list. In 2008, there were an estimated 10,000 adults in the wild in Nepal and India. Being a low-density species, FHA are particularly sensitive to changing habitat conditions and anthropogenic pressures. In India, the species is protected under Schedule-I of the Wildlife Protection Act (1972).
At present, there is little scientific information available on the four-horned antelope, and the … Read More
Tiger vs. Cow: Risk Models Help Beat the Odds
A tiger and a cow meet in a jungle. The scenario is tragically predictable: tiger kills cow, cow’s owner kills tiger. Yet in India, where repeated conflict can amount to sizeable livelihood losses and tiger declines, predicting where the scenario plays out is far from easy. However, a simple statistical method applied to mapping human-carnivore conflict could up the odds by helping people anticipate high-risk hotspots.
Our study, published in Ecology and Evolution, explored a technique that could be … Read More
Science-based Approach to Promote Human-Elephant Coexistence — Lessons from Valparai
Understanding human-elephant interactions is critical for conservation of elephants outside Protected Areas. One of the intriguing questions is how can a person weighing 50kg and a 5000kg animal coexist with no barrier between them?
Conflict incidents frequently lead to use of reactive measures such as chasing elephants, capture and translocation, or retaliatory persecution, but these often fail to resolve conflicts on a sustained basis, empower communities to implement solutions, or help conservation of elephants. Long-term research on behavioural and ecological … Read More
Mapping Sloth Bear Distribution in India and in Western Ghats of Karnataka
Endemic to the Indian subcontinent, the Sloth Bear (Melursus ursinus) inhabits tropical and sub-tropical habitats across India, Nepal, Bhutan and Sri Lanka. Being the most common among the four species of bears in India, it is widely distributed from the foothills of the Himalayas to the southern tip of the Indian peninsula. With sloth bear populations in the Himalayan foothills and northeast India becoming isolated, the Western Ghats and central Indian landscapes now possibly harbor the largest populations.
Despite their … Read More
Lessons from Leopards — Uncovering the Real Conflicts in Sanjay Gandhi National Park
This article is condensed from ‘Cities, Towns, and the Places of Nature’ (A. Rademacher, K. Sivaramakrishnan ed., Hong Kong University Press, In Press). The study in question was conducted by Frédéric Landy, Professor of Geography, University Paris Ouest-Nanterre, France, in the Sanjay Gandhi National Park (SNGP) in Mumbai, and documents the dangerous and sometimes deadly presence of leopards in and around the park. It also focuses on the fact that leopards in Mumbai are not only a matter of human-nonhuman … Read More
Help Pakke Pick its Best Images and Keep up Koro Tayem’s Legacy
In 2013, Koro Tayem, a forest guard in Pakke Tiger Reserve for more than a decade, was the first awardee for the best camera trap photograph competition. Now in its fourth year, ‘Tayem babu’ is no longer with us. On Christmas day in 2014, he was in Pakke doing his duty, and on his way back he was killed by a wild elephant. He is remembered fondly, and in 2013 we carried out a photo-feature of photographs which included his … Read More
Volunteering Can Help Save Wildlife
Participation of non-scientists as volunteers in conservation can play a significant role in saving wildlife, finds a new scientific research led by Duke University, USA, in collaboration with Wildlife Conservation Society and Centre for Wildlife Studies, Bengaluru.
The study has shown that citizen science projects greatly contribute to ‘increased environmental awareness among the general public’. It also reported direct impacts on conservation including – shift in formal profession by volunteers to become conservationists, initiation of new conservation organizations or groups, … Read More
Tracking the Incredible Journey of the Amur Falcon
Of the 69 species of raptors known from India, Amur Falcon (Falco amurensis) was one of the least talked about species till recently. Primarily recorded from northeast India, with a few scattered sight records in peninsular India, the species is generally considered rare. All that changed following a report by Conservation India in October 2012 of the massive large scale harvest of these falcons in Nagaland. Researchers estimated that between 120,000 and 140,000 individuals were being trapped and killed for … Read More
Compensation for Coexistence — Lessons from Kanha
Although attacks by tigers and leopards on livestock cause devastating losses to owners around Kanha Tiger Reserve in Central India, villagers now rarely retaliate. A prompt compensation scheme by Reserve authorities may be the secret to saving cattle-killing big cats in the wild.

Incident of a Man-Eating Tiger in Nagarahole, Karnataka
News papers have been reporting the presence of a livestock killing tiger in agricultural fields and state forests outside the eastern boundary of Nagarahole Tiger Reserve over the last few days. Unfortunately on 25-August-2012 the tiger attacked a woman grazing livestock, killed, and partially ate her. On 26-August-2012 Forest Department staff managed to locate the tiger using domestic elephants, tranquilized it and moved it into captivity.
We have been carrying out long term monitoring of tiger populations in Karnataka using … Read More
Counting Squirrels in Indian Forests
Although the ecology of squirrels has been extensively studied, most past work is characterized by the failure to account for detection and heavy reliance on indices rather than directly measuring abundance. This has involved acoustic and visual surveys, sign surveys (tracks, middens and dreys) and capture-recapture sampling (trapping rates) methods are adopted to estimate squirrel abundance. Such field studies assume the detection probability of the species to be equal in all sites, leading to incorrect estimates of true abundance.
