Scientific Name: Amphiblemma amoenum
Species Authority: Jacq.-Fél.

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2015
Date Assessed: 2015-07-16
Assessor(s): Cheek, M.
Reviewer(s): Onana, J.-M.
Facilitator/Compiler(s): Hilton-Taylor, C.
Previously assessed as Endangered (Cheek p.167, in Cheek et al. 2004, Onana and Cheek 2011), however, the assessment is changed here to Vulnerable because the species has an extent of occurrence of 1,865 km², a minimum area of occupancy of 24 km² which will not exceed the threshold of 2,000 km², and it is known from six locations (and probably occurs at other sites). There is continuing decline in extent and quality of habitat due to clearance for expanding agriculture and harvesting of wood.
Previously published Red List assessments:
2004 Endangered (EN)

Population [top]

Population: The species is very localized and rare, it appears to be known from only a few plants at each locality and all collections were made by Letouzey in 1974 and 1975.
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: A prostrate herb found in lowland to submontane forest, sometimes on rocks near streams; 800-850 m alt.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes

Threats [top]

Major Threat(s): Threatened by clearance of forest for agriculture and wood collection.

Conservation Actions [top]

Conservation Actions: The known sites should be revisited and surveyed for the species to assess whether they are included in protected areas or not. Public education might help to reduce pressure on the surviving plants. Basic population data is needed as a baseline for future monitoring. Only one site (Nta Ali) is protected by a reserve, as far as is known.
