New Delhi (ABC Live): India on Friday has taken next step in tiger conservation by announcing Phase IV of tiger conservation
This will initiate intensive, annual monitoring of tigers at the tiger reserve level, across 41 protected areas in the country, commencing from November 2011.
Welcoming the decision, Minister of State (I/C), Environment and Forests, Shri Jairam Ramesh said: “This marks an important milestone in our comprehensive tiger conservation strategy. Annual monitoring, (instead of only a four-year cycle) at the tiger reserve level will allow us to get regular updates on the number and health of tiger populations across the country, and will strengthen our tiger conservation efforts”.
What is “Phase IV”?
Phase IV of the All India Tiger Estimation exercise will begin the process of intensive, annual monitoring of important ‘source’ populations of tigers.
The methodology will be developed by the Wildlife Institute of India (WII) and the National Tiger Conservation Authority (NTCA), in consultation with experts, and will use statistically sound procedures to estimate numbers of both tigers and their prey.
The tiger monitoring protocol will use camera traps, at a density of 25 double-sided cameras per 100 square kilometres, and a minimum trapping effort of 1000 trap nights per 100 square kilometres.
This will provide a yearly indication of the status of critical tiger populations
around the country, and will be critical to long-term management and conservation of tiger populations.
Prey population monitoring will be conducted simultaneously, using Distance sampling protocols. Distance sampling will be conducted along line transects already established in phase I, and will use a minimum of 30 spatial replicates for 2 km each, and a total effort of 300 km.
The decision to begin Phase IV monitoring was made at a workshop on‘Best Management Practices in Tiger Conservation’, held from May 9th to 11th.
Framework of All India Tiger Estimation The All India Tiger Estimation exercise is one of the most crucial components of our national tiger conservation efforts. Monitoring efforts began in 2006, and are undertaken every four years, through a
three-phase approach.
Phase I: Field data collection at the beat-level, by trained personnel and using a standardised protocol.
Phase II: Analysis of habitat status of tiger forests using satellite data
Phase III: Camera trapping to identify individual tigers from their unique stripe patterns. This information was used to estimate tiger numbers in sampled sites.
The 2010 National Tiger Assessment involved three phases, and was
carried out between December 2009 and December 2010. The previous
assessment was done in 2006.
India’s Tigers 60 percent of the world’s wild tiger population is found in India.
Across a system of 41 tiger reserves, the 2010 National Tiger Assessment estimates that there are 1706 tigers (range between 1571 and 1875). This is an improvement from the 2006 estimates of 1411 tigers (range between 1165 and 1657). However, the increase is largely because the survey was expanded to the entire country in 2010. Other key outcomes of the workshop The NTCA and the WII will decide a uniform protocol for Phase IV monitoring, and will facilitate, train and provide a panel of outside experts to be involved in the same. The annual monitoring will be
carried out by the respective Chief Wildlife Wardens in tiger States.
In addition to Phase IV monitoring, the ‘snapshot’ country-level estimation will continue, and will be carried out every 4 years, covering all tiger areas. This will be implemented by the NTCA and WII.
All technical publications and data relating to tiger estimation and conservation will be placed in the public domain by the end of June, 2011.
Special initiatives will be taken to strengthen the management in problematic reserves like Indravati, Similipal, Palamau and Nagarjunasagar-Srisailam Tiger Reserves.

Govt got its math on tigers wrong? Chetan Chauhan, Hindustan Times
India may have got its latest tiger population estimation wrong. On Friday, eight top wildlife experts, in a letter published in the Science magazine, said environment minister Jairam Ramesh's announcement that the tiger population had increased from 1,411 in 2006 to 1,706 in 2010 was based on "unrel
iable" data.
The letter added to the pressure on the government to adopt a new comprehensive methodology to count the tigers. K Ullas Karanth and seven Indian and international scientists said in their letter, "These (government's) assertions cannot be verified because details of tiger photo-captures at sampled locations, as well as of spatial extrapolations from these data, are incomplete."
Ramesh hit back by accusing Karanth, a member of the ministry's National Tiger Conservation Authority, of being intellectually dishonest and said the tiger estimation was correct. "Karanth is like the species (tiger) he studies -- extremely territory-conscious and essentially a loner," he said in an email to HT.
However, the day Karanth's letter was published, asking the government to overhaul its method of estimation, Ramesh approved a new scientific plan for counting the big cat population.
The environment minister Jairam Ramesh incorporated some of Karanth's suggestions in the new plan such as annual monitoring and tiger estimation in 41 tiger reserves, wider coverage of camera-traps to capture in-depth tiger demography and greater reliability of data.
Karanth described the decision as "practical, cost-effective and useful".
Agreeing with him, Ramesh said this important milestone in the tiger conservation strategy will allow regular updates on the number and health of the tigers across India.
India has 70% of the world's tigers but most of them live in 15 reserves, constituting a mere 10% of the remaining tiger habitat.

Tiger treks 280km in search of own territory Amit Bhattacharya, TNN
NEW DELHI: A young male tiger, wandering through Karnataka's forests in search of a patch to call its own, has achieved a feat that will put it in the record books. In 15 months, the tiger travelled 280km as the crow flies, more than the straight-line distance between Delhi and Shimla, the longest documented distance traversed by a tiger anywhere in the world.
This came to light after a tiger was caught in Gama village near Shikaripur town of Karnataka's Shimoga district on May 1. It had strayed into a betelnut plantation and was stoned by a mob. The cornered tiger attacked and killed a man before it was tranquilized by forest officials.
On May 7, at an event watched by Union environment minister Jairam Ramesh, the tiger was released in the Bhadra Wildlife Sanctuary. Photographs taken during the tiger's release were analysed by scientists of the Centre for Wildlife Studies, a wildlife NGO which has been camera-trapping in Karnataka's forests for around two decades.
"Photo-matching with our database, the animal was reliably identified as male tiger BPT-241, last camera-trapped in Gundre, Bandipur Tiger Reserve, on February 11 and February 18, 2010," said Dr K Ullas Karanth, head of CWS India.
"A GIS map showed that the straight line distance moved by this tiger since its photo-capture from Bandipur to Shikaripur is about 280km. The actual distance travelled by it would be more than 350km," Karanth said.
Looking at the map, one could say the tiger would have generally moved through forest patches but would also have traversed through coffee plantations, he added.
Karanth said though young male tigers were known to travel long distances to establish their territory, this is the longest dispersal documented through camera-trapping or radio-telemetry.
In 2006, a young male tiger, BDT-130, was camera trapped in Bhadra forests and then again in Dandeli in 2008. The straight line dispersal in that case was 197km. A radio-collared tiger in Russia was found to have travelled 195km.
Late last year, a young male tiger created a scare among villagers near Mathura in western UP, which experts at the Wildlife Institute of India said, had come from Ranthambore. The tiger then made its way to the Bharatpur bird sanctuary, from where it was relocated to Sariska.
"We have not seen any documentary evidence of the distance travelled by that tiger," said Karanth. " WII has been running a camera-trapping project in Ranthambore for the past five years. If there is proof that this tiger came from there, the evidence should be made public,"Karanth added.
Meanwhile, more camera traps have been placed in Bhadra to track the fate of BPT-241. Like all tigers, he will have to compete with other males to establish his territory, Karanth said.

States squabble over who has most tigers, Amit S. Upadhye and Ambarish B Bengaluru
The latest tiger census has caused tiffs between states.
Barely a month after the Ministry of Environment and Forests released the tiger numbers for the country and its states, two states have written to the Centre seeking a re-survey of the findings on tiger numbers.
The Karnataka Forest Department has written a letter stating that the tigers from their state have been added in the numbers of Tamil Nadu. The Madhya Pradesh government has also sought a revised list of tigers, after it was reported that they had 50 tigers less than the tiger census figures of 2006.
According to officials from Karnataka, the present census count has 50 tigers less than the total number of tigers mentioned in the previous tiger census held in 2010.
The Wildlife Institute of India (WII), Dehradun, had conducted the census during 2010 and Karnataka was declared the new Tiger State of India, with 300 tigers out in the wild. It was followed by Madhya Pradesh, which has 257 tigers in the wild.
During the earlier, 2007 census Madhya Pradesh had close to 300 tigers. The decline of 43 tigers has worried the officials in that state. A official from MoEF said that both Karnataka and Madhya Pradesh forest departments have sought a re-survey since the numbers appear low, despite a higher number of direct sightings in the last few years.
Wildlife officials from Karnataka Forest Department said that a re-survey has been sought in Bandipur Forests, which abuts the Tamil Nadu forest area.
“The river Moyar divides Bandipur in Karnataka and Mudhumalai in Tamil Nadu geographically, but hundreds of animals including tigers and elephants move from one part to the other. Unlike Bandipur, which is one of the first tiger reserves in the country and well protected, the neighbouring Mudhumalai has no protection for tigers. Also the numbers which Tamil Nadu is showing, need to be checked,” said a forest official.

Despite ban, construction of canal on at Ranthambore Anindo Dey, TNN
JAIPUR: Despite an order from the Central Empowered Committee earlier in the year banning all construction work at the Ranthambore tiger reserve, a huge canal is being dug threatening to affect its ecological balance.
As environmentalists raised questions over the construction, the state government sprang into action on Saturday. The forest officials said the project has been temporarily stayed with an intervention from chief secretary S Ahmed.
Sources at the park said a100-feet wide and 5-7 km long canal is being dug between Khushalidarra and Mansarovar lake.
"The new canal has stopped the flow of water to Khushalidarra nullah and diverted it to Mansarovar," said conservation biologist Dharmendra Khandal of the Tiger Watch.
Over the past 20 days, nearly 20,000 Dhonk trees spread across at least five kms have been uprooted. The canal, Khandal said, will also destroy one of the most important tiger corridors between Ranthambore National Park and Sawai Mansingh Sanctuary.
Khandal has written to the CEC and the state government to take action in this regard.
CEC, in March, in response to a letter by conservationist Belinda Wright, had stopped all construction work at the sanctuary. Wright had complained about construction of some dams and anicuts in the sanctuary.
When contacted, officials of the state forest department expressed shock at the ongoing construction work in the reserve. Sources from the department however, revealed that the project is undertaken by the irrigation department.
