IL Y AURAIT ENCORE PLUS D'UNE CENTAINE DE TIGRES SAUVAGES DANS LA RESERVE DE KAZIRANGA (The Hindu, hier).
“Kaziranga is one of the highest density tiger habitats in the country and has a healthy breeding source population,” says a report released on Monday. It has over 100 tigers, the estimate based on the annual monitoring carried out in 2009, 2010 and 2011 using the camera trap method.
The report, “Tigers of the Kaziranga National Park, Assam, India, 2009-2011,” says 118 tigers were recorded in the reserve over the three year-period. The figure includes six tigers which died during the monitoring period.
The study was a joint initiative of the Assam Forest Department and biodiversity conservation group Aaranyak. In 2011, it was carried out in collaboration with the Wildlife Institute of India and WWF India.
Unique traits
Senior wildlife biologist of Aaranyak M. Firoz Ahmed, who led the exercise, told The Hindu that individual tigers were identified on the basis of differences in the stripe pattern on flanks, limbs, tail and forequarters.
Like human fingerprints, tigers have different stripe patterns.
The report, released by Assam Forest Minister Rakibul Hussain at a function held in the Kaziranga park, says the tiger population in the reserve was extrapolated at 106 (minimum 81 to maximum 131) by Jhala et al (2011) as published by the National Tiger Conservation Authority.
Kaziranga, which was declared a tiger reserve in 2008, covers over 1,000 square kilometres. Their major prey there, according to the report, are hog deer, sambar, swamp deer, Asiatic wild buffalo and wild pigs.
INDICATIONS D'UNE VITALITE DES POPULATIONS DANS LES SUNDARBANS; PROCHAIN RECENSEMENT SYSTEMATIQUE CONJOINT INDO BENGLADESHI EN JUILLET 2012 (Times of India du 20 Mars et du 23 Avril 2012).
KOLKATA: The first ever camera trap exercise done in the South 24 Parganas forest division has found presence of over 15 tigers.
The exercise, done jointly by WWF-India and the state forest department has photo captured 8 individual tigers in the Ramganga range and 9 in the Raidighi range. Sources said tiger presence was
found in Dhulibhashani and Chulkathi compartments in Ramganga, while Ajmalmari and Herobhanga compartments in Raidighi range also reported good tiger density.
It may be noted that over 462 square kilometres in this part of the mangrove forests will be developed as West Sunderbans
Wildlife Sanctuary.
According to sources, the entire South 24 Parganas forest division was divided into 4 square kilometres grid to locate tiger pugmarks and scats. "Later, based on pugmarks and scat presence, 20
heat motion sensitive cameras were laid in the Ramganga range covering an area of over 184 square kilometres and 21 trap camera stations were set up in the Raidighi range covering almost 216
square kilometres ," said sources. The exercise for Ramganga was done between January 23 and February 21, while trap cameras were laid and taken out in Raidighi between February 11 and March
12.
"While 8 tigers were found in the Ramganga range with a density of 5.24 tigers per 100 square kilometres , Raidighi has recorded presence of 9 tigers till March 12 with a density of over 4 tigers
per 100 square kilometres. Total 44 images were captured in Raidighi," said sources, adding that rare leopard cats, jungle cats and fishing cats too were photo captured.
The project will also cover Herobhanga under South 24 Parganas forest division and Sajnekhali Wildlife Sanctuary under Sunderbans Tiger Reserve (STR). The officials of WWF-India are meeting state
forest minister Hiten Burman and senior officials in the department today to brief them about the updated figures of the big cats photo captured between March 12 and March 19.
Sources said that the presence of the tigers will give a boost to the state's plan of developing another wildlife sanctuary in this part of the forests. "The new sanctuary - West Sunderbans
Wildlife Sanctuary - will cover Dhulibhashani 1 to 8 and Chulkathi 1 to 8 compartments . The proposed wildlife sanctuary will have Dhulibhashani 1 to its north, Bay of Bengal to its south and
rivers Matla and Thakuran to its east and west respectively," said sources, adding that while 224.26 square kilometres will fall under Dhulibhashani, 238.13 square kilometres will come under
Chulkathi.
"We will issue fresh boat licence certificates (BLCs) to the fishermen who will venture out for fishing in the area," Sunderbans Biosphere Reserve director Pradeep Vyas had said. At present, 3500
licences are given to boat owners in South 24 Parganas forest division and 960 BLCs are issued under Sunderbans Tiger Reserve (STR).
It may be noted that the Centre's tiger estimation exercise - Status of Tigers, Co-predators and Prey in India - has recently projected the number of tigers within Sunderbans Tiger Reserve
between 64 and 90.
Times View
Adecent tiger density outside the tiger reserve area shows Sunderbans - one of the last surviving natural tiger habitats in the world - still holds the potential to sustain a healthy tiger
population. Only, there should be regular monitoring and better management in the reserve, which will not only clear controversies surrounding the real number of big cats in the mangroves, but
will also throw light on the behavioural pattern of the tigers and other rare species in the forests.
KOLKATA: Finally, there will be a joint survey across 10,200 square kilometres of Sunderbans, spread across Bangladesh and India, this July to determine the exact number of tigers on the UNESCO World Heritage Site.
The numbers, given by the Bangladeshi forest department and its Indian counterparts till date, are disputed on the ground that big cats frequently cross over the Indo-Bangla border.
