Bufo olivaceous is recorded from the extreme western parts of Balochistan and adjoining Iran. Minton (1966) found little difference between B. olivaceous and B. stomaticus, while Eiselt and Schmidtler (1973) are inclined to conside it as a subspecies of Bufo stomaticus.

Life History, Abundance, Activity, and Special Behaviors
Tadpole: Typically bufonid, with oval, bulging body and weak tail. It inhabits ponds and puddles in oasis and date palm groves in Dalbandin and Kharan, southwestern Balochistan. Body is light brown, with dark specks on tail and fins, ventrum darkish white. The oral disc is typically bufonid, labial tooth row formula 2(2)/3, oral papillae are lateral. The tadpole feeds on algal vegetation and other concretions deposited on the surface of submerged objects. Total length 24-26, tail 20-22 mm.

Trends and Threats
Prolonged droughts, chemical pollution, pesticides.

Relation to Humans
Depends on wetlands created by agricultural activity, around salt lakes. It extends in human inhabitations, feeding on light attracted insects.

Possible reasons for amphibian decline

Prolonged drought
Drainage of habitat
Local pesticides, fertilizers, and pollutants
