Distribution and habitat
In 2009, the Arakan forest turtles was discovered in Rakhine Yoma Elephant Range in Myanmar. The scientific team also labeled the area as a good prospective place to focus conservation efforts for the turtle, despite the fact that locals do occasionally hunt and eat them. Even with those activities, this protected area is difficult to access and lacks any human settlement, making any human interference with the turtle merely opportunistic. No large-scale commercial project hunts the turtle, nor would there be a demand for one, since the turtle is too difficult to find compared to the little profit there is for doing so. Furthermore, the area even has a low risk of being exploited for natural resources.
In 2015, a potential population was discovered during a non-governmental organization's citizen science project, suggesting a population of the Arakan turtle may reside in the Chittagong Hill Tracts

Behaviour and ecology
The Arakan forest turtle is active at night and increases its activity during the early wet season. Local hunters found eggs in June and July when skinning female specimens, possibly revealing the reproductive system and cycle of the species.[
It remains dormant the majority of the time and hides in leaves and debris. It is an omnivore, feeding on both animals and plants. Although it is considered a relatively reserved animal for the majority of its daily activity, it is aggressive when it comes to eating insects, worms, and fish. It also consumes fruit that falls to the ]forest floor
The forest floor, also called detritus or wikt:duff#Noun 2, duff, is the part of a forest ecosystem that mediates between the living, aboveground portion of the forest and the mineral soil, principally composed of dead and decaying plant matter ...

Threats
Arakan forest turtles are being traded by animal pet dealers in China, who catch them in western Myanmar. In 2003, researchers took samples for research from nine Arakan forest turtles that had been imported to the Czech Republic to be kept in a private collection.
