Silvascincus tryoni, also known commonly as the Border Ranges blue-spectacled skink and the forest skink, is a species of lizard in the subfamily Sphenomorphinae of the family Scincidae. The species is endemic to the McPherson Range bordering New South Wales and Queensland, Australia.
The specific name, tryoni, is in honor of English scientist Henry Tryon (1856–1943). Silvascincus tryoni can grow to 104 mm (4.1 in) in snout-to-vent length (SVL). It has well-defined, dark transverse dorsal markings on a light to mid-brown background.
Silvascincus tryoni is viviparous. A female measuring 100 mm (3.9 in) SVL and 189 mm (7.4 in) total length (tail included) gave birth to five young measuring 33–35 mm (1.3–1.4 in) SVL. Silvascincus tryoni occurs in highland closed subtropical rainforest at elevations of 760–1,100 m (2,490–3,610 ft) above sea level. Specimens have been found on logs and rocks, under decayed logs, and sunning at the base of a hollow giant stinging tree Dendrocnide excelsa. When disturbed, they seek refuge under rocks and logs.

With luck
About 10% of wildlife watchers report a Border Ranges Blue-spectacled Skink sighting in Lamington National Park on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 23rd most-seen of the 38 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
March, October and December–January
In those months about 20% of wildlife watchers report a Border Ranges Blue-spectacled Skink in Lamington National Park on a given day, against under 5% in May–September and November, the lowest months. Those are among Lamington National Park's wettest months, with about 130 mm of rain a month against 40 mm in August.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Border Ranges Blue-spectacled Skink sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Lamington National Park, in our data
Lamington National Park is the only park on Wallace's Line with enough records to rate Border Ranges Blue-spectacled Skink sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Border Ranges Blue-spectacled Skink is recorded against all the reptiles logged in Lamington National Park (26 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.
