Overview

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

Cylindrocline commersonii faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its native range in Mauritius. Invasive plant species have significantly altered the forest understory composition, reducing suitable microhabitats for this endemic species. The species' extremely limited distribution makes it particularly vulnerable to localized disturbances and climate-related changes affecting montane forest ecosystems.

Threat summary

Habitat

This endemic species inhabits the remaining fragments of native montane forests in Mauritius, typically found in humid upland areas with dense canopy cover. It occurs in association with other native flora in forest understory environments at elevations between 400-800 meters above sea level.
