Population
[top]
| Population: |
It is apparently an abundant species within its small range, and a survey in 2003 succeeded in locating several individuals, even during the cold season when they are supposed to be inactive.
|
| Population Trend: |
Decreasing

Habitat and Ecology
[top]
| Habitat and Ecology: |
It is a species of montane grassland. It is a viviparous species, with the female nourishing the young internally prior to the birth of small toadlets.
|
| Systems: |
Terrestrial |
| Major Threat(s): |
Habitat loss and degradation due to the mining of iron ore/bauxite is the biggest threat to this species, and new mining sites have been selected recently for mining in the Guinean part of Mount Nimba. There is a risk that mining could destroy the entire range of the species. Fires in the montane grassland might be a threat. The species is inherently at risk because of its small range.

Conservation Actions

| Conservation Actions: |
This species presumably occurs in the Mount Nimba Strict Nature Reserve, which is a World Heritage Site. It is listed on CITES Appendix I. Survey work is necessary to monitor the population status of this species.
