Scientific Name: Adelophryne baturitensis
Species Authority: Hoogmoed, Borges & Cascon, 1994

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Débora Silvano, Diva Borges-Najosa
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Vulnerable because its extent of occurrence is less than 20,000 km², all individuals are in fewer than ten locations, and there is continuing decline in the extent and quality of its habitat in the Maciço de Baturité.

Geographic Range [top]

Range Description: This species is known only from the Serra (or Maciço) de Baturité, in the State of Ceará, north-eastern Brazil, at 600–1,000 m asl.

Population [top]

Population: It was very common within its small range, and often found at numerous localities since it was first described up until 1993; however, from 1994 to 2003 there were 34 surveys of the same sites and not a single individual was found, until in July 2004 three individuals were recorded.
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: Most specimens have been found in dry or moist leaf-litter on the ground, in bromeliads, and stream margins in reasonably well-preserved closed forests. However, it can also survive in shaded coffee plantations. It is a diurnal species that breeds by direct development, and the eggs are probably deposited in wet spots on the ground.
Systems: Terrestrial

Threats [top]

Major Threat(s): The major threat is habitat loss due to logging, agriculture, and human settlement. The very good soils and favourable climate of the area are encouraging agricultural expansion, and the species is unable to survive in the banana plantations that are rapidly taking over the area.

Conservation Actions [top]

Conservation Actions: It is not known from any protected areas, and there is clearly a need for improved habitat protection at sites where this species is known to occur. Further survey work is needed to determine whether or not this species is experiencing a decline, or whether or not it is just undergoing natural population fluctuations.
