Wild Boar

Wild swine (Sus scrofa)

Tabulation for the national park is based on actual counts at the major villus and an estimated density for the riverine system based on inference from the highest counts at the major villus which are utilized by the swine. This gave us overall an estimate of 180 animals for the 580 square kilometer area; however, litter sizes are large in the swine and there may be dramatic fluctuations in actual count of animals throughout the annual cycle.

Muntjac (Muntiacus muntjac), Mouse Deer (Tragulus meminna), Porcupine (Hystrix indica), and Langur (Presbytis entellus)

Estimates for these species were based on counts made at Kali Villu and Marai Villu and we assumed that the density for these two major villus would be equivalent for the remaining six larger villus within the park. Populations for smaller villus were estimated to be at half that for larger villus and the average density per unit area of usable habitat at the larger villus was set at the density estimate for our 38.8 square kilometer area of riverine habitat. Since these species are not particularly mobile, we considered them to be more or less bound to permanent water. Therefore, their total density estimates are based on considerations similar to those for the axis.
