Ecology and habitat
The tree skink is largely an arboreal (tree-dwelling) species that can be found in hollow logs and cracks, behind the bark of standing and fallen trees. They are rarely rock dwelling in NSW. In South Australia, they frequently use rocks and tree crevices and exfoliating slabs. They have been found under the ‘skirts’ of Xanthorrhoea spp. This species can also be found in disturbed habitats such as fence poles.
Egernia striolata tend to aggregate socially, in small groups of 2 to 4 individuals. They have a recognition system not found in any other Egernia genus.
Mating season occurs in September and October.
Egernia striolata is listed as “Least Concern” in the IUCN Red List with a current Stable population. It has no specific conservation actions.
