Balthasaria mannii

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Balthasaria mannii faces severe threats from habitat destruction due to agricultural expansion and urban development in its limited range. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes and human activities. Deforestation and land conversion for farming have significantly reduced available habitat, while the small population size increases extinction risk from stochastic events.

Threat summary

Habitat

This species inhabits tropical moist forests and forest edges in West Africa, typically found in areas with dense canopy cover and high humidity. It appears to prefer undisturbed primary forest habitats with specific microclimate conditions.
