Geography comments: "in the Ratnapura district... The site consists of approximately 40 acres spread across a hilly terrain, with its altitude ranging from 80-1100 m asl" (coordinate based on Ratnapura District)

Environment
Habitat: tropical/subtropical moist broadleaf forest

Altered habitat: plantation

Protection: unprotected

Substrate: ground surface

MAT: 31.0

MAP: 4000.0

Habitat comments: "regenerating tropical rain forest... The site was managed as a rubber plantation till year 2003, which was subsequently abandoned in order to initiate a restoration program to establish a tropical rainforest. The area receives an annual rainfall of over 4000 mm, and the mean temperature is around 31ยบ C"

Methods
Life forms: lizards,snakes,frogs

Sites: 4

Sampling methods: no design,hand capture

Sample size: 273 individuals

Years: 2011

Sampling comments: "Field observations were made over a period of four months, extending from April to July 2011... Observations were made by walking through representative terrestrial habitat types, and at the edge of man-made ponds during day and night time. Torch, and head lamps were used to observe species during night time. The specimens encountered were caught, measured (the length from the tip of the snout to the vent), sexed, and checked for any deformities"
there were four "Sampling replicates per habitat type" (presumably meaning separate sites)
