Nearly half of the mammalian species in Sri Lanka are present in the Sinharaja forest region. Sinharaja is one of the few refuges of two arboreal non-primate mammals – the Golden palm Civet (paradoxurus zeylonensis) and Small flying squirrel (Petinomys fuscocapillus). The endemic and threatened primate – The purple-faced leaf Monkey is also found in the Sinharaja forest. A small herd of elephants roaming around the Delwala, Walanakanda and Rakwana range occasionally frequent the north-eastern part of Sinharaja. These elephants form one of the two populations remaining in the wet zone. Direct and indirect observations on the herd roaming the above areas indicate a population of 3-4 animals, including a well-grown bull. Compared to the dry zone elephants, they are dark in colour and much stouter in appearance. A lucky visitor may get the chance of observing an elusive wild cat in Sinharaja, either the Leopard, Fishing Cat or the smaller Rusty-Spotted Cat.
