Kanneliya–Dediyagala–Nakiyadeniya or KDN is a forest complex in southern

Gin and Nilwala Rivers. This biosphere reserve harbors many plants and animal species endemic to Sri Lanka
.

Physical features

The biosphere consists series of parallel mountain ranges and valleys. The elevation ranges from 60 m to 425 m above sea level.[4] Mean annual temperature is 27.0 °C while annual temperature variation is 4 °C-5 °C. The forest receives a substantial rainfall of 3,750 mm. Many ancient taxonomic groups of Gondwana are present in these rain forests. They also relates to Indomalayan plants and animals.

Hydrological features

The forest complex act as an important

Gin River, which flows west to the forest and for Nilwala river which flows east to the forest.[4]
Kanneli, Nanikiththa and Udugama are the smaller streams of Kanneliya while Homa dola and Gal bandi dola are sourced by Nakiyadeniya and Deiyagala.

Flora

The KDN forest complex shows a degree of floral

emergent layer
of the forest.

Numerous

Lycopodium phlegmaria ("Maha hadaya") are among the rare plants the forest complex harbors.[4][5] The near-threatened Palaquium hinmolpedda ("Hinmolpedda") is also found here.[6]

Fauna

Some 220 faunal species recorded from the KDN forests and forests around the KDN.

herpetofauna are 36 species of snakes, 17 endemic species belonging to 6 families. A total of 23 species of lizards
recorded in these rain forests.

Human imprint and conservation

10,000 people live in 78 villages around the forest complex.

rubber and cinnamon plantations, animal husbandry and other forms of agriculture and cottage industries are main economic activities take place around the forest. Nugegoda, Rajagala and Dediyagala hermitages situated within the forest. The forest complex was subjected to logging, until suspending in 1988.[3] Fortunately the diversity of species and plants remains largely intact. A forest corridor between Sinharaja Forest Reserve and the KDN forest complex is being planned for facilitate animal movement between the two forests.[8] Green-billed coucal, Sri Lanka blue magpie, ashy-headed laughingthrush and white-faced starling are the bird species listed as endangered.[9] 27 percent of floral species are listed vulnerable, and 45 percent are in the rare plants category.[3]
