Dasia olivacea, the olive dasia or olive tree skink, is a semi-arboreal species of skink lizard native to Southeast Asia.

The species is originally known from a single locality in Cambodia. The northernmost extreme for D. olivacea is possibly the Sakaerat Environmental Research Station in the Nakhon Ratchasima Province of eastern Thailand. Dasia olivacea lives almost exclusively in trees, only rarely descending to nest or to move between trees. Eggs may be laid more than once per year, in clutches of up to 14 eggs; incubation lasts 69 days. Because it is very widespread and ecologically flexible, D. olivacea is considered to be a species of Least Concern on the IUCN Red List.
Dasia olivacea was first described by John Edward Gray, in a publication of the Annals of Natural History (1839), as the type... Wikipedia →

With luck
About 10% of wildlife watchers report an Olive Dasia sighting in Khao Yai National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 30th most-seen of the 46 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
March–April and June–July
In those months about 20% of wildlife watchers report an Olive Dasia in Khao Yai National Park on a given day, against under 5% in May and August–February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Olive Dasia sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.

GBIF citizen-science records
It is estimated from how often the Olive Dasia is recorded against all the reptiles logged in Khao Yai National Park (8 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
