Adolfus jacksoni, also known commonly as Jackson's forest lizard, is a species of lizard in the family Lacertidae. The species is native to East Africa. A. jacksoni is named after Frederick John Jackson, who was an English colonial administrator and ornithologist.
A. jacksoni is found in Burundi, eastern Democratic Republic of the Congo, Kenya, Rwanda, Tanzania, and Uganda. The preferred natural habitat of A. jacksoni is forest at altitudes of 450–3,000 m (1,480–9,840 ft), but it will tolerate some human disturbance.
A. jacksoni is diurnal and semi-arboreal. A. jacksoni is oviparous, and clutch size is three to five eggs. Large communal nests have been found, and these nesting sites have been reused. A. jacksoni is preyed upon by the venomous viper Atheris nitschei.

With luck
About 10% of wildlife watchers report a Jackson's Forest Lizard sighting in Ngorongoro Conservation Area on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 9 reptiles we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
March–April and July
In those months about 20% of wildlife watchers report a Jackson's Forest Lizard in Ngorongoro Conservation Area on a given day, against under 5% in May–June and September–February, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Jackson's Forest Lizard sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Jackson's Forest Lizard sightings, Ngorongoro Conservation Area ranks 2nd at about 10%. The best odds are in Bwindi Impenetrable National Park (Uganda, about 40%).
GBIF citizen-science records
It is estimated from how often the Jackson's Forest Lizard is recorded against all the reptiles logged in Ngorongoro Conservation Area (6 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.
