Gaertnera truncata

Declining

Overview

Gaertnera truncata is a species of plant in the family Rubiaceae. It is endemic to Mauritius. Its natural habitat is subtropical or tropical dry forests.

Gaertnera truncata faces severe threats from habitat destruction and fragmentation across its limited range in the Western Ghats of India. The species is particularly vulnerable to agricultural expansion, urbanization, and infrastructure development that have dramatically reduced its forest habitat. Climate change poses an additional threat through altered precipitation patterns and temperature shifts that affect the moist forest conditions this species requires.

Threat summary

Habitat

Gaertnera truncata is endemic to the moist evergreen forests of the Western Ghats in India, typically found in shaded understory environments with high humidity and consistent moisture levels. The species requires intact forest canopy cover and is associated with specific soil and microclimate conditions found in these biodiversity hotspot forests.
