Animalia Chordata Amphibia Anura Ceratophryidae

Scientific Name: Chacophrys pierottii (Vellard, 1948)
Common Name(s):
Spanish Escuercito

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Annotations:
Needs updating
Assessor(s): Lucy Aquino, Ignacio De la Riva, Steffen Reichle, Ismael di Tada, Esteban Lavilla
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Population [top]

Population:It is not well known from Bolivia and Paraguay, but the Argentinian populations appear to be large and widespread. This species is rarely seen except when juveniles leave ponds where they develop.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species can be found in Chaco dry shrubland and gallery forest. It is an explosive breeder during the first heavy rains, breeding in temporary ponds. outside breeding season adults remain buried underground. It does not adapt well to anthropogenic disturbance.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): It is collected for the international pet trade, and subject to heavy collecting during the breeding season. It is threatened in Argentina by the destruction of Chaco habitat for agriculture and wood extraction, land and water pollution caused by agrochemical runoff.

Conservation Actions [top]

Conservation Actions: It occurs in several protected areas: Kaa-Iya in Bolivia, and PN Defensores del Chaco in Paraguay. Occurs in the Chancani Provincial Reserve, the Formosa Natural Reserve, Teuquito Multiple Use Reserve in Argentina.
