Scientific Name: Beccariophoenix alfredii Rakotoarinivo, Ranarivelo & J.Dransf.

Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2012
Date Assessed: 2010-12-17
Assessor(s): Rakotoarinivo, M. & Dransfield, J.
Reviewer(s): Baker, W.J., Beentje, H.J. & Bachman, S.
Justification:
Known with certainty (based on specimens) from only one location with a very restricted area of occupancy (about five kmĀ²). The area is at present not that impacted by human activities although there are some villages in the area. There is good anecdotal evidence for other populations of this palm nearby which needs to be investigated further. Given the very restricted nature of the population any increase in human activities leading e.g. to increased fire frequency or increased exploitation of this species could potentially drive it to Critically Endangered in a very short time period, hence its listing as Vulnerable.

Population [top]

Population:Restricted to banks of the Mania River and its tributaries, about 1,000 mature individuals are estimated in this single site.
Current Population Trend:Stable
Additional data:
Number of mature individuals:900-1100
Population severely fragmented:No
All individuals in one subpopulation:Yes

Habitat and Ecology [top]

Habitat and Ecology:Grows in gallery forest, on sands and quartzite rocks along a river. This species is the dominant element in the gallery forest at its occurrence site.
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Unknown

Use and Trade [top]

Use and Trade: Seeds are collected in the wild and then exported for sale in the international horticultural market.

Threats [top]

Major Threat(s): Threatened by increasing frequency of fires and through the harvesting of seeds for horticulture which might impact future regeneration.

Conservation Actions [top]

Conservation Actions: Further field work is required to determine if the species occurs elsewhere. Monitoring of the seed harvest may be required to see if this is a significant threat to the species.
