Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA MANTELLIDAE

Scientific Name: Mantella bernhardi
Species Authority: Vences, Glaw, Peyrieras, Böhme & Busse, 1994
Common Name(s):
English Bernhard's Mantella, Black Mantella, Tolongoina Golden Frog
Taxonomic Notes: Molecular data indicate the existence of at least two different management units for conservation in this species, corresponding to the north and south of its distribution range (Andreone et al. 2006; Vieites et al. 2006).

Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(iii,v) ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Raxworthy, C.J. & Cadle, J.
Reviewer(s): Stuart, S.N., Chanson, J.S. & Cox, N.A.
Justification:
Listed as Endangered because its Area of Occupancy is probably less than 500km2, its distribution is severely fragmented, and the extent of its forest habitat in east-central Madagascar is declining, and the number of mature individuals might also be declining through over-exploitation.

Geographic Range [top]

Range Description: Until recently, this species was known only from a single locality, (next to Tolongoina, south-east Madagascar) but recent fieldwork has extended its known range by the discovery of several new populations, all in south-eastern Madagascar, from Parc National de Ranomafana (at Mangevo) south to near Manambondro, at 60-629m asl (Rabemananjara et al. 2005; Andreone et al. 2006; Glaw and Vences 2007).

Population [top]

Population: It is locally abundant, but there is very limited suitable habitat within its range.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It lives in rainforest, including in very tiny patches. It is now found only in degraded rainforest, probably because of severe habitat degradation within its range. It is not found in open areas, nor in littoral forest on a sandy substrate. It presumably breeds in swamps or small streams, with the eggs being laid on the ground near water.
Systems: Terrestrial; Freshwater

Use and Trade [top]

Use and Trade: Most animals in international trade originate from the single collection locality of Ambohimanana/Ambohimandroso (Andreone et al. 2006). International trade in this species is regulated by CITES and related national export quotas (Andreone et al. 2006).

Threats [top]

Major Threat(s): The area where the species occurs is being degraded rapidly due to subsistence agriculture, timber extraction, charcoaling, livestock grazing, fires, and expanding human settlements. It is also possible that over collecting for commercial and private purposes is a threat.

Conservation Actions [top]

Conservation Actions: It is found in the Manombo Special Reserve and Parc National de Ranomafana. There is a need for trade in this species to be carefully regulated including the maintaining limited exportation quotas. Attention should be given to conservation of the two distinct population conservation units of this species (Andreone et al. 2006). It is listed on CITES Appendix II.
