Scientific Name: Charopa lafargei Vermeulen & Marzuki, 2014
Taxonomic Source(s): Vermeulen, J.J. and Marzuki, M.E. 2014. 'Charopa' lafargei (Gastropoda, Pulmonata, Charopidae), a new, presumed narrowly endemic species from Peninsular Malaysia. Basteria 78(1-3): 31-34.

Assessment Information [top]

Red List Category & Criteria: Critically Endangered B2ab(iii) ver 3.1
Year Published: 2014
Date Assessed: 2014-04-30
Assessor(s): Vermeulen, J., Marzuki, M. & Seddon, M.B.

Justification:
This species is apparently restricted to the isolated limestone hill Gunung Kanthan in Peninsular Malaysia close to the limestone quarry 3.5 miles southwest of the hill. This species is found on limestone rock outcrops within primary limestone forest. The area was in proximity to a nearby Hindu temple, providing some influence on forest management, and as such the initial threats were likely to lead to a Vulnerable assessment (under criterion D2). However the cement company Lafarge Malaysia is currently in negotiation with the various temples around the hill to use the habitats for quarrying hence the continued presence of the forests and adjacent temples is no longer guaranteed, as when quarrying starts, the forests will be logged, and these habitats will be lost with the adjacent forests degraded due to limestone dust pollution.

The forest habitat is also being possibly being degraded by the presence of adventitious oil palm seedlings from the adjacent plantations which may continue to impact the original forest habitat.

As such, with multiple threats to the habitats for this species, and the new threat of habitat loss, the assessment is Critically Endangered, with the likelihood of extinction when quarrying operations are commenced.

Threats [top]

Major Threat(s): The primary limestone forest in this area was previously in proximity to a nearby Hindu temple, providing some influence on forest management but the cement company Lafarge Malaysia is currently in negotiation with the various temples around the hill to use the habitats for quarrying hence the continued presence of the forests and adjacent temples is not guaranteed, as when quarrying starts, the forests will be logged, and hence the habitats will be lost, and the adjacent regions will suffer from dust pollution.

The forest habitat is also being possibly being degraded by the presence adventitious oil palm seedlings from the adjacent plantations which may continue to impact the original forest habitat.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation actions in place for the mollusc. The changes in land management may adversely affect the habitats of this species.
