Kaudulla National Park is a national park on the island of Sri Lanka located 197 kilometers away from the largest city, Colombo. Along with Minneriya and Girithale, BirdLife International has identified Kaudulla as an Important Bird Area.
The vegetation of the park represents Sri Lanka's dry evergreen forests. Chena cultivation and grasslands surround the tank area. The community of phytoplankton in the Kaudulla tank includes blue green algae, Microcystis spp. and diatoms such as Melosira spp.. Manilkara hexandra, Chloroxylon swietenia and Vitex altissima are the dominant tree species in the forest surrounding the tank. Bushes such as Randia dumetorum, and Calotropis gigantea and grasses such as Imperata cylindrica, and Panicum maximum are abundant in some areas.
Sri Lankan Sambar Deer, Sri Lankan Axis Deer, Chevrotain, Wild boar, Sri Lankan Leopard, and Sloth Bear are other mammals found in the park. Kaudulla National Park is also one of the sites in which the Gray Slender Loris is reportedly found in Sri Lanka. Following the discovery of a two month old albino Sri Lankan Axis Deer calf abandoned by her mother, it is supposed that Kaudulla is probably the only national park in Sri Lanka to have albino Axis Deer.
Large water birds such as Spot-billed Pelican and Lesser Adjutant visit the Kaudulla tank. Fish species in the tank include the freshwater Oreochromis mossambicus. Fejervarya pulla is an endemic amphibian to Sri Lanka that inhabits the National Park. Freshwater turtles, Indian Flap-shelled Turtle and Indian Black Turtle are the noteworthy reptiles.
