[7] Diasporus gularis is a very common frog occurring in both primary forest and disturbed habitats, including deforested areas,[1] at elevations up to 1,770 m (5,810 ft) above sea level[3] but mostly below 400 m (1,300 ft).

This adaptable species occurs also in many protected areas and is not facing significant threats.
