12. โขConservation - Eastern Ghats "Save the snakesโ-initiative under " Pollination Project โ
King Cobra was listed vulnerable under IUCN Red list of threatened species, has been
selected as ambassador.
Causes - Indiscriminate killing, poaching and road kills. Also habitat loss and degradation.
STS aims to build capacity within local tribes of Eastern Ghats through education ventures,
empowered citizen scientists who would eventually deal with the human snake interactions
more effectively and also assist in their conservation.
80% of snakes in Eastern Ghats area are non poisonous and harmless even if they bite. The
venomous ones are - Common cobras, banded Krait, Russell vipers, Bamboo pit vipers.
Awareness programme -
Kanti Mahanti Murthy representative of Eastern Ghats Wildlife Society and STS said
"The initiative aims to improve the livelihoods of people who live in areas with high
incidence of conflict with snakes and educate the locals to minimise rampant killing
of the reptiles of Eastern Ghats."
'Para ecologist' - local people who could continue the conversation activities in their
respective villages irrespective of the project period or expiry.
- Indigenous local knowledge
- Proper training in snake handling
- Field surveys to assess species distribution

20. Threats to humans
India being a country
higly vulnerable to
human-snake conflict,
the number of
deaths/Casualties are
maximum around the
villages.
One of the main
reasons to such a
conflict is settling of
snakes around human
settlements in search
of rodents.
The official records
however, lack in
proper record keeping
of the casualties
around the country.
21. In the case of venomous snakes like
cobras, the fangs are crudely
extracted, and the venom glands
are painfully gouged out or
punctured, thus disabling the
snakeโs only means of defence,
feeding, and digestion, essentially
condemning it to a slow,
excruciating death. Non-venomous
snakes are not spared either, and
have their mouths stitched shut,
making it impossible for them to
eat..
The Wildlife Protection Act of 1972
bans, and has a prison sentence
for, any form of trapping, snaring,
capturing, or even hunting of
snakes, and using them for display
and entertainment.

22. โขAccording to the current laws the maximum punishment for murdering an endangered
species like a King Cobra is three to seven years in jail and a fine of ten thousand rupees
for first offence and twenty five thousand for second offence. And offences related to
trade and commerce in animal trophies, articles derived from certain animals will result
in a maximum punishment of three year imprisonment and fine upto Rs. 25,000/- I am
sure, you will agree that this is not a deterrent enough and the wildlife crime syndicates
are able to easily get people to work in their channels.
