Brookesia therezieni, also known as the Perinet leaf chameleon, is a species of lizards in the family Chamaeleonidae. The species is endemic to eastern Madagascar. The International Union for Conservation of Nature (IUCN) classed the species as Least Concern. B. therezieni was initially described as a species new to science by Édouard-Raoul Brygoo and Charles Antoine Domergue in 1970.
The specific name, therezieni, is in honor of French hydrobiologist Yves Thérézien. Endemic to eastern Madagascar, Brookesia therezieni is found in the type locality of the species, Périnet, which is why it is known as the Perinet leaf chameleon. It is also found in the east-central area of Madagascar: An'Ala, Ankeniheny, Andasibe, Anjanaharibe, Mantadia, and Imerimandroso. It can be found at elevations between 900 and 1,500 m (3,000 and 4,900 ft) above mean sea level, and is estimated to be found over an area of 30,444 km2 (11,754 sq mi). Its preferred natural habitat is forest.
B. therezieni is oviparous. The International Union for Conservation of Nature has ranked B. therezieni as Least Concern on its Red List... Wikipedia →

Possible
About 20% of wildlife watchers report a Permet Leaf Chameleon sighting in Ranomafana National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 23rd most-seen of the 29 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
January and September
In those months about 40% of wildlife watchers report a Permet Leaf Chameleon in Ranomafana National Park on a given day, against under 5% in February, April, June–August and December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Permet Leaf Chameleon sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Ranomafana National Park, in our data
Ranomafana National Park is the only park on Wallace's Line with enough records to rate Permet Leaf Chameleon sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Permet Leaf Chameleon is recorded against all the reptiles logged in Ranomafana National Park (10 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.
