Stelechantha arcuata

Declining

Overview

Pauridiantha arcuata, synonym Stelechantha arcuata, is a species of plant in the family Rubiaceae. It is endemic to Cameroon. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.

Stelechantha arcuata faces severe threats from habitat destruction as its native forest ecosystems are cleared for agriculture and urban development. The species' extremely limited range makes it particularly vulnerable to localized environmental changes and human disturbance. Climate change poses an additional threat by altering the specific microhabitat conditions this specialized snail requires for survival.

Threat summary

Stelechantha arcuata faces severe threats from habitat destruction as its native forest ecosystems are cleared for agriculture and urban development. The species' extremely limited range makes it particularly vulnerable to localized environmental changes and human disturbance. Climate change poses an additional threat by altering the specific microhabitat conditions this specialized snail requires for survival.
Where does Stelechantha arcuata live?
Stelechantha arcuata occurs in Cameroon. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
