Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii)+2ab(iii); D2 ver 3.1
Year Published: 2011
Date Assessed: 2007-09-21
Assessor(s): Gerlach, J.
Reviewer(s): Rankou, H. & Fay, M.
Justification:
Malaxis seychellarum is endemic to Mahé and Silhouette, where it is restricted to a area of occupancy (AOO) of 10 km2. It is found in fewer than 10 locations and is threatened by ongoing habitat deterioration due to the spread of invasive species. Reduction in humidity due to climate change is a potential future threat. It is therefore listed as Vulnerable.

Geographic Range [top]

Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Found in the dampest areas of high forest above 400 m asl.
Systems: Terrestrial

Threats [top]

Major Threat(s): Threatened by ongoing habitat deterioration caused by invasive species (especially Cinnamomum veurm and Psidium cattleianum). The cloud forest habitat may be threatened by humidity reductions caused by climate change. A number of intrinsic factors, such as limited dispersal, low densities and restricted range, are also potential threats.

Conservation Actions [top]

Conservation Actions: Present in the Morne Seychellois and Silhouette National Parks. Like most orchids this species is listed on Appendix II of CITES.
