Fly ash, once a major pollutant, now an asset (September Week 1 (2006))
Used for applications like making bricks
Fly ash from thermal power plants, once a major air pollutant, is
now being made into bricks or added as a mixture to cement for
building construction, laying of roads and landfills.
"Fly ash is not a waste, but an asset," was the theme of the
Tiruvallur District Fly Ash Implementation Committee's second
meeting on Tuesday at the Ennore Thermal Power Station and the
North Chennai Thermal Power Station .
Ash generation in the three units at ETPS is expected to go up to
3,000 tonnes. The ash was collected manually till December 2005,
from April 14, the collection has been through the pressurised dense
fly ash collection system (PDFACS) and lifted through bulkers. The
remaining fly ash and bottom ash is mixed with seawater as slurry
and pumped into ash dykes and kept as wet ash.
In 2005-06, utilisation of fly ash was 26.17 per cent, exceeding the
target of 20 per cent. There will be 100 per cent utilisation by the
end of 2007 with the help of PDFACS and use of wet ash for road
and land filling works.

Most tiger reserves violate norms: CAG (September Week 1 (2006))
The ambitious Project Tiger programme of the Centre has come in
for sharp criticism from the Comptroller and Auditor General (CAG)
which found that many tiger reserves do not even adhere to the
prescribed norms for a core area or protected zone of a sanctuary.
While the norms for tiger reserves prescribe an average area of
1,500 sq km with at least 300 sq km as the core area, the CAG
report for 2005 found that 15 of the 28 tiger reserves spanned less
than 720 sq km.
Six of these 15 tiger reserves had a core area of less than the
prescribed 300 sq km, it said, noting that such discrepancies existed
despite the knowledge that tiger population grows rapidly in
The CAG found that human settlements existed in the core areas in
half of the tiger reserves, including Ranthambore, Sariska, Panna
and Pench. The result has been an increase of just 20 tigers in 18
years in 15 tiger reserves created till 1984.
The Project Tiger Directorate (PTD) admitted that human
settlements disturb tigers but said the areas were brought under the
project considering the threat to the tiger population there. The
CAG also pulled up the PTD and state governments for the delay in
notifying the tiger reserves as National Parks, which would provide
a legal basis for ensuring protection.
“In many tiger reserves the final declaration procedures of National
Park, core and buffer, were pending as of March 2006 even though
the amended Wildlife (Protection) Act, 2003, set a time limit for
completion of acquisition proceedings,” it said. The final notification
declaring the area as a National Park was not issued in Indravati,
Kanha, Pench, Palamau, Bandhavgarh, Panna, Simlipal and Kakkad
Mundanthurai till March this year despite these being declared as
tiger reserves in 1973-75. “This depicts (a) lack of commitment on
the part of state governments while denying legal backing to the
boundaries of the reserves,” the CAG report stated.
The state governments have also drawn the ire of the CAG for the
lack of any special anti-poaching drive or any stringent action in
cases of tiger killings. A test check in the audit revealed that out of
the 46 cases of poaching registered during 2000-05 in the Sariska
Tiger Reserve in Rajasthan, 13 were tiger cases. The PTD drew
criticism for the absence of a communication network in as many as
nine reserves and deficiencies in creation of strike forces and
provision of arms and ammunition to forest staff to check poaching.
Several tiger reserves reported shortage of weapons, with
Nagarhole and Bandipur having 21 and 31 weapons against a
requirement of 191 and 123 respectively.
The CAG report said the implementation of Project Tiger was
severely hampered by under-staffing. And, the personnel employed
were under-trained and under-equipped. The CAG has also
suggested that all Tiger Reserves should have a well-formulated
management plan for appropriate allocation of resources.

Forest department begins "bio-fencing" (September Week 1 (2006))
The Coimbatore Circle of the forest department in
association with the animal husbandry department has started a
bio-fencing exercise by vaccinating stray cattle in the fringe areas of
the reserve forest.
Bio-fencing is vaccinating and de-worming domestic cattle in the
fringe areas of the forest against the dreaded and common diseases
such as Anthrax and Foot and Mouth to ensure that they do not act
as carriers of any disease when they venture into the jungles for
According to the Conservator of Forests, Coimbatore Circle,
Rakesh Chandra Purwar, the exercise has already been completed
along the fringe areas of the forest along the boundaries of Indira
Gandhi Wildlife Sanctuary and National Park at Pollachi. A similar
drive was being planned across the Coimbatore division and in the
divisions and wildlife sanctuary in the Nilgiris across the
Coimbatore Circle. Vaccination of wildlife is not possible hence
vaccination of the domestic cattle, say sources.
The animal husbandry department provided the vaccine, manpower
and expertise, while the forest department provided the ground
support and logistics in vaccinating the domestic cattle in the
villages across the reserve forest boundaries.
Vaxination camps helped in vaccinating thousands of cattle along the boundaries of the reserve forest.
The effort is just to prevent spreading of diseases when the
domestic cattle stray into the forest and establishes an interface
with the wildlife through water, food or excreta. Due to lack of
awareness, the cattle owners failed to bring it to the dispensaries for
vaccination. Through this bio-fencing exercise the forest department
provided a platform besides the logistics for vaccinating the stray
cattle against dreaded diseases.
The forest department was not only preventing diseases to wildlife
by getting the stray cattle vaccinated but also mobilising the
villagers to avail the services of the animal husbandry department.

Presence of leopards, wild dogs detected in Krishna forests (Issue of the week, May Week 4 (2006))
Census reveals no sign of tigers, bears and hyenas
· Nearly 40,000 acres of pristine jungle exists in the reserve forest areas
· Census conducted using the `line transact method' to locate carnivorous animals
In the reserve forests of Krishna district, leopards and wild dogs top the list of carnivores in food chain in the absence of tiger population. This came to light in the census of carnivorous and herbivorous animals conducted by the Forest Department recently.
According to statistics, nine per cent of the total geographical area of Krishna district is covered by forest. Huge stretches of the 1.94 lakh acres of the forest have become degraded and partly have fallen to encroachments. But there is 30,000 acres of pristine
jungle in Kondapalli Reserve Forest and another 10,000 acres in the Gaddamarugu Konduru Reserve Forest. Large carnivores and herbivores often stray into the G. Konduru Reserve Forest from Khammam district. The Forest Department conducted the census using the
line transact method to search for all carnivorous animals like tigers, leopards (also referred to as panthers), wild dogs, bears, hyenas, jackals and wolfs. Pugmarks and faecal matter have confirmed the presence of leopards (Pathera pardus) and wild dogs
Divisional Forest Officer K. Suryanaryana says that Forest Department staff and others have confirmed the presence of wild dogs, which is evident from the howling and other vocalisations often heard in the jungles. However, there are no signs of tigers, bears
and hyenas in the reserve forest of the district.
A large number of jackals (Canis aureus), one wolf (Canis lupis pallipes) and one civet cat (Vivarricula Indica) have been also recorded in the census for carnivores.
Plenty of wild boars (Sus scrofa) are found in the survey for census of herbivorous animals. Marks of many large herbivores like Sambar (Cervus unicolor) and Chital (Axis axis) have also been recorded.
A limited number of barking deer (Muntiacus muntjak) and four-horned antelope (chowsingha) (Tetracerus quadricornis) have also been sighted. Other mammals like Rhesus monkey (Rhesus macaque) langur (Presbytis entellus), hare (Lepus nigris collies) porcupine
(Hystrix indica) exist in good number. Peacocks and jungle fowl are the large birds that inhabit the forests.
The Forest Department has created several water holes and salt licks to help the large animals to protect themselves from the heat of the summer, Mr.Suryanarayana says. The Sattemma Talli temple tank in the heart of Kondapalli reserve forest and other tanks
date back to the British times, he says.

Diclofenac banned, to be phased out in three months (May Week 4 (2006))
The Drug Controller-General of India, Ashwini Kumar, has issued a directive seeking withdrawal of Diclofenac, a painkiller for cattle. He has asked for phasing out of all such formulations within three months.
Finally agreeing with environmentalists and bird lovers the world over, Mr. Kumar has admitted that Diclofenac is the main cause of deaths of vultures in the subcontinent, which consume carcasses of animals administered with the medicine. Mr. Kumar has suggested
an alternative drug once Diclofenac is phased out.
The decision to ban Diclofenac has been taken after consultations with the Director-General of Health Services and the Union Agriculture Ministry. Sources said directives had been issued to Drug Controllers in all the States to carry out the ban with immediate

Govt to move out swamp deer to other habitations (May Week 4 (2006))
The Wildlife wing of the Madhya Pradesh Forest Department would start working on an ambitious plan to relocate the swamp deer (Cervus duvaucelii branderi) or barasingha from the Kanha National Park to other sites in the state. The idea behind the move
is to have the barasingha population spread over other locations, apart from Kanha, in order to shield it from possible epidemics that could take a heavy toll on the deer population.
Principal Chief Conservator of Forests (Wildlife) PB Gangopadhyay, while speaking to the Pioneer, said work on the plan would begin soon with the identification of alternative sites. "A site, which was formerly a human settlement with open spaces in the form
of a meadow and swamps, would be ideal for the relocation of barasinghas," he said. Such sites would be scouted around and the possibility of finding one would be high in Satpura National Park.
Presently, the entire barasingha population in the state is concentrated in Kanha National Park. The subspecies Cervus duvaucelii branderi at Kanha is not found anywhere else in the country and is classified as endangered. There are about 300 species found
The state forest department has been attempting to get Asiatic lions from the Gir National Park in Gujarat for the Kuno Palpur Sanctuary in Sheopur district of MP. The efforts have not borne fruit as yet but the relocation is being sought on the grounds that
if an epidemic were to strike at Gir, the entire lion population would be susceptible to it. The forest department is applying the same logic to the barasingha population in the state and is now looking out for alternative sites for its relocation.
