Nagpur: Even as the maiden experiment by the state forest department to radio-collar two tigers in Tadoba-Andhari Tiger Reserve (TATR) has been hailed by experts in the field, it is high time such research is carried out outside protected areas (PAs) where wildcats are becoming victims of man-animal conflict.

After TOI report on October 20, a section of readers claimed that looking into the death of a tigress T4 due to radio collar infection in Panna tiger reserve in MP on September 18, it is a waste of money to place satellite collars on tigers. However, wildlife experts dubbed these comments as immature.

Conservationist Prafulla Bhamburkar says such research is needed more outside Tadoba landscape where 17 villagers have been mauled to death by big carnivores this year. 'Pombhurna tiger, which was shot dead, could have been saved had it been radio-collared," he added. PCCF (wildlife) Sarjan Bhagat admits that tigers outside PAs need better protection but says as of now there is no proposal to collar them. "We will moot a separate proposal," he said.

Radio collar is one of the best tools to understand tiger behaviour, predation, population and ecology. Not a single tiger died of radio-collaring, because it is just 1% body weight of that species, say experts. If we want to save a species at its population level, we need to understand its ecology using reliable tools.

Panna field director RS Murthy denied that T4 died of collar infection. "The tigress died naturally due to some internal health problem. It will be known once we get clinical reports from respective agencies," Murthy said.

"Radio collars are the best help managers with least invasive observations of any mega carnivore. We are doing it for last five years," Murthy added.

In 2009, a wildlife intelligence report had blamed tiger deaths in Panna on their 'radio collaring', raising questions over the projects to conserve the animal throughout the country.

However, Bombay Natural History Society (BNHS) director Asad Rahmani says it all depends on who did it and for what purpose? Studying animal movement and ecology by radio-collaring/satellite tracking are well-known methods used all over the world.

"New tracking technology is giving us remarkable results about animal behaviour and movement. So, it is wrong to say that radio-collaring per se is bad. If there is a purpose and clear objective, there is nothing wrong in radio-collaring," said Rahmani.

"It is wrong to say that Panna tigress died due to radio-collaring. If this is the reason, why other animals do not die? Every major operation on human being has some risk. So, should we stop life-saving operations due to the small risk involved?" said Rahmani.

In November 2012, the state wildlife wing had for the first time placed a radio collar on a rescued tigress which was released post treatment at Tass near Bhiwapur. "The collar gave valuable insights into the secretive world of big cats in the wild. Radio-tracking actually helps curb menace of poaching since tiger movement is constantly monitored and the ones which stray or are killed are immediately noticed," says wildlife biologist Vidya Athreya, who placed the collar on the Tass tigress.

Athreya says there will always be accidents but with more and more such scientific activities happening, it will also allow us to improve our skills. "It is likely that the Panna tigress had a wound on her neck which the collar did not allow for healing," Athreya says.

Athreya adds that in a place like Africa, where visibility is good and there are not as many people as in India, you can drive up to the animal, see it clearly and then intervene if the animal has a problem with the collar etc.

"But if you ask me about the scene 10 years back and now, things with respect to understanding, management and the use of new tools have really improved in Maharashtra. I think this is a very good thing," Athreya said.

just thought i'd add it in there, the report is from two weeks ago.

 

A couple of things,
Forrest Department is not Scientist or Biologists. They are hired by the Tiger park and are a private service. They would wan't tigers to wear collars since its already been showed that the collared tigers are beign tracked and ran out by VIP tourists to guarantee a sighting.

There is already a conclusive study that the Tigress died due to infection from a wound from the collar.

There have also been Collared tigers who have been poached same with other collared animals. So obviously a collar my offer a little protection it still isn't fool proof. And lets not forget that the collared animals are usually in protected parks that have heavy tourism. Which is far more protection than animals in other areas that are not protected.

Now lets look at how many animals have now been studyed like never before because of camera traps

Camera traps capture exciting animal behaviour across India
0 1 51

Posted on 22 May 2012 | 5 Comments
The utility of camera traps
Camera traps are invaluable, non-invasive and cost effective tools that provide wildlife researchers with photographic data that can be used to estimate density and abundance of a specific species, proof of presence of a species in an area and trends in population change due to anthropogenic pressures, among other data. Such data derived from the systematic and scientific use of camera traps help conservationists in taking management and policy decisions.

In India, camera traps are well known as the tools used for the science based All India Tiger Estimation Exercise conducted by NTCA/WII with support from WWF and other NGOs. What is not so well known though is that camera traps are also very good at offering insights into the behaviour of wild animals and revealing new distribution records for a species.
WWF-India’s use of camera traps across India
Over the past few years, WWF-India in partnership with NTCA and different state forest departments has been deploying camera traps across India towards estimating tiger numbers, estimating the presence of specific species, and understanding human-wildlife conflict.

These camera traps used in varied and diverse habitats, from the forbidding heights of Kargil to the dense forests of Western Ghats, have revealed hitherto seldom seen behaviour and activity of wild animals.
Leopard-Hyena fight
For the past one and half years, WWF-India has been monitoring cattle kills by large carnivores in the critical Kanha Pench corridor forests of Central India using camera traps as part of a project to provide interim relief to local communities to reduce retaliatory poisoning of tigers and leopards.

These camera traps captured a rarely seen and perhaps never before photographed scene in India – a hyena (Hyaena hyaena) and a leopard (Panthera pardus fusca) fighting over a cattle kill, probably made by a tiger. The photograph provides an insight into the complex ecological interactions between carnivores and shows how scavengers utilize a kill made by a large carnivore, signifying the intricate food chain.
Changeable Hawk-Eagle (Dark morph)
Moving eastwards, camera traps setup near a waterhole in the Sunderbans forests captured an uncommon dark morph variant of the Changeable Hawk-Eagle (Spizaetus cirrhatus). While the eagle is easily seen across India’s forests the dark morph has very scarce sightings.
Fishing cat with prey
A camera trap in the Kaziranga National Park in Assam captured one night a fishing cat (Prionailurus viverrinus) coming back from a successful hunt with its favourite prey - a fish. The fishing cat, as their name suggests, are skilled swimmers and excellent at catching fish and this capture aptly confirms their nocturnal hunting abilities.
Clouded leopard
Elsewhere in Assam, camera traps photographed one of the lesser-known members of the cat family, the clouded leopard (Neofelis nebulosa) in Manas National Park. The camera traps documented a good density of these cats from this park, a density exceeding that of the tigers in Manas!
Eurasian magpies
The far north of India, Kargil to be more precise, is snow leopard country. This mysterious denizen of the heights sometimes comes down during the lean winter months from his high altitude haunts to hunt livestock. The kill, after the snow leopard has had its fill and left, attracts a host of scavengers like the Eurasian magpies (Pica pica). This capture from Kargil shows a flock of these magpies congregating at the site of the kill (not visible in photo) to feed on the carcass demonstrating the complex food web that interlinks large carnivores and birds in such high altitude areas where food sources can be scarce during winters.
Asiatic black bear
The Senchal Wildlife Sanctuary located in Darjeeling is home to a sizable population of the Asiatic black bear (Ursus thibetanus). The aim of the camera trapping exercise here was to study the distribution patterns of the Asiatic black bear and analyse its habitat as well as determine the scale and tendency of human-bear conflict. The distribution patterns of the bears determined from the camera trap captures would help in reducing human-bear conflict in the area by undertaking plantation of more fruiting trees in areas known to be frequented by these bears, thereby reducing chances of them venturing out of the sanctuary into human areas in search of food. This capture shows a Asiatic black bear and her cub foraging for food inside the Sanctuary indicating that healthy breeding is taking place in the Sanctuary.
Rusty-spotted cat
The camera trapping exercise in the forests of Pilibhit revealed a completely new distribution record for the rusty spotted cat (Prionailurus rubiginosus) in the Terai Arc landscape. The previously known distribution record for this cat is from the states of south and central India and parts of western India. In this case, the camera traps discovered a hitherto unknown distribution record for the smallest wild cat.
Hyena kill
This camera trap shows a Hyena scavenging a chital, probably a kill made by a larger carnivore. Captured in the Sathyamangalam forests of Tamil Nadu, an area proposed to be declared a tiger reserve, this photo is indicative of the good density of hyenas found in this region. Overall, one of the best populations of hyena in India is found in this region, a crucial connecting link between the Eastern and Western Ghats.

As these captures amply demonstrate camera traps can, apart from generating baseline data about presence and abundance of wildlife, also provide valuable insights to wildlife researchers about the behaviour of wild animals and aid conservationists in implementing effective conservation management plans.
