Introduction
Nagarjunasagar
spreads over five districts, Nalgonda, Mahaboobnagar,
Kurnool,
Prakasam and Guntur, in Andhra Pradesh state of India. The Krishna
river flows through the Reserve over a distance of 130 km. The
multipurpose reservoirs, Srisailam and Nagarjunasagar, which are
important sources of irrigation and power in the State are located
in the Reserve. The reservoirs and temples of Srisailam are major
attraction for a number of tourists and pilgrims from all over
the country and abroad.
The area is hilly, considerably varying from plains to precipitous
cliffs. High hills, deep valleys and gorges are characteristic
features. More than 80 per cent of the area is gently rolling
to hilly. The hill ranges contain number of plateau of which Amrabad,
Srisailam, Peddacheruvu, Sivapuram, Nekkanti are note worthy.
Nagarjunasagar receives rains from South-West monsoon as well
as North-East monsoon. The South-West monsoon is active from second
half of June to end September. After a dry spell of one month
during October, North-East monsoon becomes active.
The Wildlife is generally confined to plateaues during monsoon
and in valleys during summer. The perennial water sources are
generally located in the valleys and the plateaus suffer from
acute scarcity for water during summer.
The River Krishna is the oldest river in the country, which has
cut its basin almost 200 m deep. Many water falls such as Ethipothala,
Pedda Dukudu, Gundam and Chaleswaram are amazingly beautiful.

The
Nagarjunasagar-Srisailam Sanctuary was notified in 1978. It was
declared a Tiger Reserve in 1983. The Reserve was renamed as Rajiv
Gandhi Wildlife Sanctuary in 1992. Before independence, the southern
half of the Reserve area was under the control of the British
while the northern half was controlled by the rulers of princely
State of Hyderabad, who maintained it as a reserve for royal hunting.

Archeology
This
area contains ruins of the ancient Nagarjuna Viswa Vidyalayam
run by the great Buddhist scholar Nagarjunacharya (150 A.D.).
The ruins of the fort of Ikshwaku Chandragupta a ruler of 3rd
century B.C. are present in the area overlooking a valley called
Nirjivapuram (Lifeless city). The ancient fort of Pratap Rudra
a king of Kakateeya dynasty and many other forts are seen on the
banks of the "Krishna". An ancient wall over a length of 105 miles
constructed by the Kakateeyas is an interesting feature.
This area contains a number of geo-morphological features e.g.
rock shelters and cave temples such as 1) Akka Mahadevi Bhilam,
2) Dattatreya Bhilam, 3) Umaa Maheswaram, 4) Kadalivanam, e) Palankasari.
The ancient shrines of Lord Mallikharjuna and his consort goddess
"Bhramaramba" respectively contain one of the 12 Jyothirlingas
and one of the eighteen Maha Shakthi peethas of the country.

Management
Practices,
Achievements and Shortfalls
Protection
is the most important input of the management. Water and fire
management as well as improvement of habitat have been keen issues
dealt with by the Reserve Management.
Improvement of water resources was given top priority. Existing
small tanks were deepened to ensure more water storage. Forty
check-dams were constructed to increase number of water points
by arresting water in the streams which otherwise would have gone
unutilized. Seventy artificial water troughs were constructed
and water is supplied through tankers as frequently as necessary
in high scarcity areas. Salt licks were also provided.
The fire hazard is considerably reduced by creating more fire
lines and maintaining the existing ones. During summer separate
fire fighting squads are deployed to extinguish the fire in the
initial stages itself.
Weeds, Parthenium and Lantana, were recently removed from 3000
ha, near the water holes.
The compensation for cattle and human kills were paid as early
as possible.

Special Projects
The
Andhra Pradesh State Electricity Board (APSEB) is going to provide
Rs. 50 million for conservation in lieu of forest land diverted
for erection of 400 KV transmission line through the Reserve.
The main components of the scheme are habitat improvement; water
conservation; maintenance of buildings, roads, wireless network
etc.
Documentation of ethnobotanical knowledge of the tribes by Dr.
P. Ramachandra Reddy, P.G. College of Science, Hyderabad.
Ethnobotanical medical plant wealth of Nagarjunasagar by
Dr. R.R. Venkata Raju, S.K. University, Anantapur.
New Initiatives
Eco-development
Implementation
of eco-development activities in forest dependent villages has
bridged the gap between management and the communities. The villagers
have started realizing the need for conservation of bio-diversity.
They are now cooperating with the management in curbing destruction
of habitat. Involvement of community in decision making is now
yielding encouraging results.
The families dependent on commercial exploitation of fuel wood
are being encouraged to take up alternative income generation
activities.
Endeavor was made to improve the fodder resources by raising grass
plots in the vicinity of tribal villages, to cater to their needs
and to reduce the grazing pressure in the forest areas.
In order to reduce the fuel wood consumption, the non-conventional
energy sources like biogas plants and solar lamps have been introduced
to a limited extent. Apart from this the smokeless chullahs and
portable chullahs were also provided to the villagers.
One important component of the eco-development is education and
awareness. This has brought a dramatic change in the attitude
of the extremists towards environment. Now they are not causing
any harm to the habitat or staff.
Village Forest Protection Committees
Eco-development
committees (EDCs) numbering 115, have been constituted in and
around the Reserve not only to reduce the dependency of the villagers
but also to check and plug all the smuggling routes in the forest.
Most of the committees have already taken the conservation of
the habitat as a major concern. Apart from this 85 Vanasamrakshna
Samithis are functioning outside the Reserve, which in conjunction
with EDCs spare no efforts to destruction of forest. With the
help of these committees, protection level has increased.
Protection of tiger has received a particular boost due to EDCs.
The EDCs have become mechanisms reporting of cattle kills and
tiger poisoning from remote and inaccessible areas of the tiger
reserve. To encourage open dialogue about cattle kills and to
prevent retribution, Tiger Conservation Programme, WWF-India was
instrumental in developing a package of compensation /rewards
for the reporting of such kills by villagers. This has been highly
useful.
Protection Squads / Patrolling
Environmental
Education for a better understanding and appreciation of the Reserve
is being imparted. Forest department had published brochures,
pamphlets, posters, and stickers. One Environmental Education
Centre is functioning at Srisailam since 1988, and attracts most
of the tourists visiting Srisailam Temple. The second one at Mannanur
is in the offing. The Environmental Education Centre has video
and movie library. The films are screened at the Centre as well
as in the adjoining villages. The Centre attracts about 50,000
people annually.
Infrastructure and Facilities
Three Forest Rest Houses and 40 bed capacity dormitories are available
for tourist occupation in this Tiger Reserve, at Srisailam, Mannanur
and Nagarjunasagar. There is connection to Srisailam from Hyderabad,
Vijaywada, Guntur, Kurnool, Markapur. The distance from these
town to Srisailam ranges between 90 to 240 km.
Education and Awareness
A
Nature Education and Interpretation Centre has been established
at Semadoh. Around 50 thousand people visit this centre annually.
Two orientation centres at Akot and Harisal, and an interpretation
centre at Amravati are also planned.

Constraints
Human population
About 200 villages are situated in and around the Nagarjunasagar-Srisailam
Tiger Reserve of which 120 villages are within the sanctuary limits.
The overall population density is 0.2 persons per km2. The population
grew at the rate of 1.3 per cent over the inter-census period
1981-1991.
There are 24 villages, comprising 557 families with a population
of 2285, in the core.
8432 families with a population of 43978 in Non-core are residing
within the sanctuary limits. Remaining 80 villages with 24531
families consisting of 1,22,751 people are in the fringe.
Livestock population
There
are about 15000 domestic animals in the villages in the core area.
The annual growth is around 400. Livestock population in non-core
part of the Reserve is 43350. Around three lakh migratory cattle
enter into the Reserve from the plains, immediately after the
onset of monsoons.
Encroachment
Since the inception of Tiger Reserve, no encroachment has been
noticed. There are some old encroachments.
Grazing
Migratory cattle posing threat to the habitat.
Fire
The forest floor is set to fire for new flush of grasses by the
migratory cattle grazers
Poaching of fauna and flora
The forest of the Reserve is an oasis and meets the demands of
small timber and fuel wood of all the surrounding districts. Timber
is smuggled down to the plains.

Criminals and Extremists
The
presence of extremists in this area is evident. The subordinate
staff is literally scared to move freely in the interior of the
Reserve. Vehicle movement is also restricted. However, a wireless
network connecting few important places has been established.
Highways
One
highway passes through the Reserve, vertically over a length of
140 km., from Mannanur in Mahaboobnagar District to Dornal in
Prakasam District Another highway runs along the southern boundary
of the Reserve over a length of 50 km. from Nallaguntala to Bairlutty.
Diseases
No
record.

Conflicts
Man-Animal
Any
problem related to man-animal or man-forest is being resolved
by the ecodevelopment committees.
Man-Forest
About
840 families are dependent on fuel selling. About 550 families
in Mahaboobnagar and Kurnool districts are dependent on collection
of Adda leaves for leaf-plate making. At times, for easy and
increased procurement of Add a leaves, the supporting tree on
which the climber twines, are felled. In all around, 1060 families
are depending on this business earning an amount of Rs.15.90
lakh per annum.
