Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA MANTELLIDAE

Scientific Name: Boophis occidentalis
Species Authority: Glaw and Vences, 1994
Taxonomic Notes: This species was previously considered to be a subspecies of Boophis albilabris, but it was raised to full specific rank by Andreone et al. (2002). The north-western population could perhaps belong to an undescribed species (M. Vences pers. comm.).

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2004
Date Assessed: 2008-01-01
Assessor/s: Frank Glaw, Miguel Vences, John Cadle
Reviewer/s: Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Justification:
Listed as Near Threatened since the species depends on streams in a dry environment, and so its Area of Occupancy is probably not much greater than 2,000 km2, and the extent and quality of its habitat is declining, thus making the species close to qualifying for Vulnerable.

Geographic Range [top]

Range Description: This species has been recorded from four widely separated localities in western and north-western Madagascar: Isalo; Bemaraha; Sahamalaza, and outside the Réserve Spéciale de Kalambatritra. It occurs from close to sea level up to 800m asl.

Population [top]

Population: There is little information on the population status of this species, but it can be locally abundant.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It lives in dry and transitional forest, and has been found in severely degraded habitats with planted trees along streams in a village, although it probably cannot survive in completely open habitats. It is an explosive breeder in streams.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threat to this species is rapid habitat loss and degradation due to subsistence agriculture, timber extraction, charcoal manufacture, livestock grazing, fires and expanding human settlements. It is probably also affected by pollution of its breeding streams.

Conservation Actions [top]

Conservation Actions: It occurs in Parc National de Isalo and is likely to occur in the Réserve Spéciale de Kalambatritra, although it has not yet been found there. It also occurs in one planned protected area (Sahamalaza).
