It can be found at a mid-altitude over an area of about 2057sqkm, although this is not confirmed. The International Union for Conservation of Nature have classed this species as "data deficient", as not enough information on this species is available to correctly classify it. The population of this species is unknown and no population trend is known. It is found in an area where the habitat is affected by the slash-and-burn agricultural method, bushfires, and logging. Calumma fallax is used in the pet industry and is sometimes domesticated.
