Elephants are a visible feature in the Park, and herds can be sighted quite frequently. Among the other residents are the sloth bear, leopard, water buffalo, toque monkey, spotted deer, sambar, porcupine, Indian muntjac, jackal, fishing cat, wild boar, and several other smaller animals.
This Park is one of the recorded habitats of the grey slender loris while the European otter has also been reported here.


The white-bellied sea eagle, great cormorant, the painted stork, the black-hooded oriole, woodpecker, Sri Lanka’s national bird - the jungle fowl, and the malkoha, amongst others, make their presence evident - if not very audible.
Interestingly, around the reservoirs, the Asian openbill, spot-billed pelican and the Oriental darter take centre stage, along with the black-headed ibis and the Eurasian spoonbill.
Moving around in an inconspicuous manner, are the water and common monitor, estuarine and mugger crocodile, the introverted Indian star turtle, and snakes such as the common cobra and black-tailed python. Giant gourami, catfish and snakeheads are just some of the fish found in the reservoirs.
The Park boasts of abundant dry zone vegetation. Weera, palu, buruta, kaluwara welang, ehela, kumbuk, milla, kone and fruits like beli and woodapple are all found here.
