Taxonomic Notes: Removed from synonymy with Boophis boehmei by Vences et al. (2010) and in the Boophis goudotii group according to the original publication (Frost 2013).

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2015
Date Assessed: 2014-11-23
Assessor(s): IUCN SSC Amphibian Specialist Group
Reviewer(s): Stuart, S.N.
Contributor(s): Hutter, C., Glaw, F., Riemann, J. & Scherz, M.
Facilitator/Compiler(s): Luedtke, J., Hobin, L. & Coals, L.
Justification:
Listed as Near Threatened because its extent of occurrence is 14,995 km2, its entire population is suspected to occur in forest patches between which there is little to no dispersal and is thus severely fragmented, and there is ongoing decline in the quality and extent of forest habitat throughout its range. However, due to the species' tolerance to a degree of habitat degradation, having been found in degraded rainforest, it is uncertain whether the population is declining. The species is therefore close to qualifying for the Vulnerable category under criterion B1ab(iii), and further research is required to establish the impact of ongoing threats on its population.

Geographic Range [top]

Range Description:Boophis quasiboehmei occurs in southeast Madagascar where it has been found in and around Ranomafana National Park and Andohahela National Park. It is presumed to occur in suitable highland habitat between these sites. Records of this species have been made at altitudes of approximately 750-1,020 m (Vences et al. 2010).

Population [top]

Population:There is little available information about the species' population size or abundance, other than that it is infrequently seen, but its larvae are commonly found in streams within its range (Vences et al. 2010). Despite its relative resilience to degraded habitats, the species' dependence on forest suggests that population declines caused by habitat loss could be ongoing, albeit slow.
Current Population Trend:Decreasing
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:Boophis quasiboehmei inhabits primary as well as degraded rainforest. Adult specimens are only found occasionally, and can occur in densely clustered demes along forest streams where the males call at night from perches 2–3 m high. Within the Ranomafana National Park, Boophis quasiboehmei larvae have been found to occur commonly within streams (Vences et al. 2010).
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: There are no records of this species being utilized.

Threats [top]

Major Threat(s): This species has a relatively large distribution and appears to be fairly tolerant to habitat degradation, however there are a number of threats to this species' habitat. There is ongoing decline in the extent and quality of its forest habitat due to subsistence agriculture, timber extraction, charcoal manufacturing, invasive spread of eucalyptus, livestock grazing, regular burning to maintain cattle pasture, expanding human settlements, and the impact of increasing artisanal mining. There is some encroachment of these threats into the boundaries of both National Parks.

Conservation Actions [top]

Conservation Actions: Conservation Actions
Boophis quasiboehmei
 is known to occur in both Ranomafana and Andohahela National Parks. Ranomafana is presently well-managed, but is potentially at risk if political instability weakens enforcement (M. Vences pers. comm. December 2010).


Conservation Needed
The extent of the species' range outside the Parks requires habitat protection and the species' habitat within the Parks would benefit from improved protection.


Research Needed
In order to inform the need for further conservation action, more information is needed on this species' distribution, population status, natural history, and its tolerance of threatening processes.
