Hibiscus noli-tangere

Unknown

Overview

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

Hibiscus noli-tangere faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range in Madagascar. The species is particularly vulnerable to invasive plant species that outcompete native vegetation in its specialized coastal and lowland forest habitats. Climate change poses an additional threat through altered precipitation patterns and increased cyclone intensity, which can devastate the fragmented populations of this endemic hibiscus.

Threat summary

Habitat

This endemic Malagasy species inhabits coastal forests and lowland woodland areas, typically growing in well-drained soils at elevations below 800 meters. It shows preference for forest edges and clearings where it can access adequate sunlight while benefiting from the protection of surrounding native vegetation.
