The researchers found that tigers living in the area died sooner and had fewer offspring than did animals living in road-free areas 7. In , Pariwakam and a group of non-governmental organizations sued the government to stop the expansion of the NH44 to four lanes. The fight lasted eight acrimonious years before WII scientists and the conservationists came to a compromise: underpasses that animals could use to walk safely beneath.
Finished in , the NH44 has 9 specially built underpasses, ranging in length from 50 to metres, designed to allow animals to pass beneath the roads. These are the longest animal underpasses in the world, and the first in India.
A tiger was killed trying to cross a train track near Jaldapara National Park, India. But although the underpasses are excellent on paper, Pariwakam questions their efficacy. Since , two leopards and one tiger have walked across the road rather than using an underpass and were hit and injured.
As we inspected one structure, a 44 careened into view from a village access road and drove through the underpass to a service ramp leading to the highway. Pariwakam whipped out his phone and filmed the intrusion. He has been urging the forest department to close off all access roads. This year, news about tiger deaths and fatal attacks on humans has popped up almost every week. As reserves have filled up, tigers are moving into the forest corridors that connect them — which are also used by people.
Tigress T49 was born in the corridor enclosing the Chandrapur district, outside the Tadoba Andhari tiger reserve, not too far from Pench. There are people per square kilometre here, living in villages that are slowly encroaching into forests.
In December , T49 had four cubs, named E1 to E4, in a culvert under a bridge. Villagers thronged on tractors and motorbikes to see the newborns. They have collared 23 individuals so far, a small sample size. But this is still the largest telemetry, or tracking, study of tigers in the world. Their preliminary data are troubling. They suggest that non-reserve tigers move longer distances daily, perhaps to avoid humans and get around infrastructure.
Habib says that of five tigers that left a reserve the team was monitoring, four died from walking into electrified wires. In March , the scientists collared E1, E3 and E4; E2 was shy and escaped, a trait that might serve her well amid humans. E1 was special. E1 favoured a forest fringing a village. On 6 April, an older woman went into the forest to collect flowers of the mahua tree, used to make liquor. As she crouched down, her posture made her look like small prey, researchers suspect.
A tiger emerged without a sound and pounced. It dragged the woman 3 metres, then dropped her and disappeared. There were two more human kills in three weeks. Scientists and the forest department are racing to understand ways to minimize such human—animal encounters.
Some are using camera traps to warn villagers when tigers are in their vicinity. Their efforts are urgent because the death toll is rising. Across central India, villagers have killed 21 tigers through electrocution, traps or poisoning since In Chandrapur alone, tigers have killed 24 people in the past 4 years.
Tigers often attack people from behind, so a honey collector in the Sundarbans wears a mask on the back of his head to ward off trouble. In June, the forest department captured the tiger E1 and moved her to a wildlife rehabilitation centre, making her the ninth individual to be relocated since Much like the animals they study, tiger scientists are fiercely territorial.
Everyone except Karanth at the Centre for Wildlife Studies requested anonymity while speaking about politics because it could hinder their ability to do research.
Several scientists say there is a conflict of interest because government managers fund and oversee science as well as set policies regarding reserves. Karanth says managers grant research permits more easily to scientists from the government-run WII than to independent scientists, unless the latter join government-led studies as junior partners.
Independent observers also charge that government scientists sometimes rubber stamp government actions, whether or not they are scientifically sound. An example is the NH44 road project: although the WII initially recommended much larger overpasses to the government, it reworked its assessment to reduce costs and make it more palatable under pressure from government officials, according to a government report.
Most independent field initiatives have shut down, says Karanth. His year-long study of tigers in southern India ended in because the local forest officials had been repeatedly interrupting or delaying his work — for example, by not allowing his assistants access to field sites.
The union and state government officials ignored his complaints. Government officials and researchers challenge those criticisms. Nitin Kakodkar, who is the chief wildlife warden of Maharashtra and signs off on research permits in his state, disagrees that WII scientists are favoured or that the managers influence research.
WII scientists, he says, are more knowledgeable about the permit requirement procedures than are independent scientists. He also said that India is tirelessly working with all 13 tiger range countries towards nurturing the tiger.
The minister announced that his ministry is working on a programme in which efforts would be made to provide water and fodder to animals in the forest itself to deal with the challenge of human-animal conflict which is causing deaths of animals. Lidar is a method for measuring distances by illuminating the target with laser light and measuring the reflection with a sensor.
Highlighting the keystone nature of the tiger, a poster on the presence of small cats was also released by the Environment Minister. The detailed report of the 4th All India Tiger Estimation is unique in the following ways--Abundance index of co-predators and other species has been carried out which hitherto was restricted only to occupancy; Sex ratio of tigers in all camera trap sites has been carried out for the first time; Anthropogenic effects on tiger population have been elaborated in a detailed manner, and Tiger abundance within pockets in tiger reserves has been demonstrated for the first time.

Asked if India is doing enough to cooperate with neighboring countries to preserve tigers since the animal does not know borders, Karanth said this largest wild cat has been wiped out on both sides of the border along, more so along the China-Myanmar region.
About increasing man-animal conflict, Karanth said "a few well-protected tiger habitats are producing surplus tigers" which are dispersing away and coming into conflict with humans. If not, local hostility will be unmanageable," he said. Commenting on India's success, as a signatory of St. In the census the number was 4, and in it was deliberately brought down to 1, so that officials can play these games. The real number is most likely to have been around 3, for the past two decades.
Use of poor methods and hiding the data from independent scrutiny are how things are being done," he said. Indian Prime Minister Narendra Modi had claimed that the country has completed this target of doubling the tiger population in , four years ahead of the deadline. The WWF is run at a local level by the following offices Frequently Asked Questions - Tiger. The Indian tiger has an orange coat patterned with broad black stripes. It has black ears, each with a winking white spot on the back, powerful forepaws, and a long banded tail.
The total length of the tiger from the tip of its nose to the end of its tail is between 2. The average life span of a tiger in the wild is about 14 to 16 years. Eight sub-species of tiger existed in the past out of which three have been extinct for many years. The population found in Peninsular Malaysia has been given a status of separate sub species Panthera tigris jacksoni.
The three sub species of tigers that became extinct in the past century are: the Bali Tiger Panthera tigris balica that was found in the Indonesian island of Bali, the Javan Tiger Panthera tigris sondaica that was found in the Indonesian island of Java and the Caspian Tiger Panthera tigris virgata that was found in Iran, Iraq, Afghanistan, Turkey, Mongolia, Kazakhstan, Caucasus, Tajikistan, Turkmenistan and Uzbekistan.
Recent reports indicate that the South China tiger is also extinct in the wild. Recent genetic studies indicate that the Caspian and Siberian tigers may have been the same sub species.
What is an Indian tiger? The tiger has an orange coat patterned with broad black stripes. The diet of an Indian tiger mainly consists of large wild ungulates such as chital Axis axis , sambar Cervus unicolor , barasingha Cervus duvacelii , nilgai Boselaphus tragocamelus and gaur Bos gaurus and other animals such as the wild pig Sus scrofa. It is an opportunistic feeder and can also kill large prey such as elephant calves Elephas maximus , gaur Bos gaurus and wild buffalo Bubalis arnee.
Tigers may occasionally also kill sloth bear and leopards as well as smaller prey such as peafowl, langur, jungle fowl, hare etc. Due to their large body size tigers are not good tree climbers like leopards. They can only climb along large leaning trees. But tigers are excellent swimmers and love water. Tigers are known to swim between islands in the Sunderbans. Indian tiger. Where do you find tigers in India? Tigers are found in a variety of habitats, including tropical and sub tropical forests, evergreen forests, mangrove swamps and grasslands.
In India, tigers are found in 19 states. For the better management of tiger habitats, forests have been demarcated as Tiger reserves, National Parks and Wildlife Sanctuaries, also known as Protected Areas.
There are 39 Tiger Reserves in our country today, some of which were added recently. For more details about the tiger reserves visit www. Map showing state wise tiger numbers. What are white tigers? White tigers are not a separate sub-species, but are white in color due to an expression of recessive genes.
Interestingly, the white tigers are found only among the Indian tigers and can only be seen only in captivity now. The last white tiger reported in the wild was captured in the forests of Rewa in the state of Madhya Pradesh. The white tigers found in the zoos today are most likely descendants of this one tiger that was caught from the wild in Madhya Pradesh and later bred in captivity. White tigers have pink noses, white-to-cream coloured fur, and black, grey or chocolate-coloured stripes.
