The
Conservation of Reptile fauna
of Sri Lanka
Legal protection to reptiles came into effect when the 1937 Fauna
and Flora Protection Act (FFPA) was declared in 1938. In this,
only the Water Monitor ( Varanus salvator ) was listed as a
protected reptile. The situation was substantially changed by the
seventh amendment to the act in 1993, in which according to the
provisions in section 30, all Sri Lankan reptiles, excluding the 5 highly venomous land snakes (Bungarus caeruleus,
Bungarus ceylonicus,
Naja naja,
Daboia russelii and
Echis carinata)
were listed as protected species. As these five
species are capable of causing death to humans, they are not given
legal protection. (Gunawardena,1995).
According to the 1999 list of threatened species of Sri Lanka published by IUCN, 87 (55.4%) species of the inland reptiles (excluding marine forms) are
considered to be nationally threatened. This includes an alarming
amount of 82.7% endemics. Out of the listed species, 12 species have
been categorized as 'Highly Threatened (HT), while the other 75
species are listed as 'Threatened (TR)'. [Table 1]

As Sri Lanka is a signatory to the CITES (Convention on the
International Trade of Endangered Species), commercial trade of
species between countries has been restricted. According to the
convention, eight species of Sri Lankan reptiles are listed under the
Appendix I and nine under Appendix II. [Table 4]

The Department of Wildlife Conservation and the
Forest Department of Sri Lanka have declared several wildlife
protected areas, which have a large role in the in situ
conservation of the reptiles as well as the other animals and
plants in the country. The declared protected areas include (as
up-to May 2008), three Strict Nature Reserves [Hakkgala,
Yala central & Ritigala]; 20 National Parks [e.g. Ruhunu (Yala),
Wilpattu, Galoya, Kumana (Yala-East), Udawalawe, Lahugala, Maduruoya,
Wasgomuwa, Flood plains, Somawathi, Horton plains, Bundala,
Lunugamwehera, Minneriya-Giritale, Kaudulla, Horagolla, Hikkaduwa
(marine) & Pigeon islands (marine)]; four Nature Reserves [Thrikonamadu,
Minneriya-Giritale, Wetahirakanda & Flood plains]; 62 Wildlife
Sanctuaries and
two wildlife
corridors. Additionally there are proposed
wildlife refuges and some buffer
zones which are not officially declared as yet.
The forest department also manages a considerable number of forest
reserves.
Ultimately it
appears that successful conservation of reptiles in the country will
have to largely depend on educational organizing. Without good
extension work, which encourages the full participation of local
people to implement and maintain conservation plans in their areas,
there are few good prospects for protection of the reptiles and other
wildlife species in the country.
