Tarenna nilagirica

Unknown

Overview

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

Tarenna nilagirica faces severe pressure from habitat fragmentation and degradation across the Western Ghats, where its montane forest habitat is increasingly converted for agriculture, plantations, and urban development. The species' restricted range in the Nilgiri Hills makes it particularly vulnerable to localized threats, while invasive plant species compete with native understory vegetation that this endemic shrub depends upon. Climate change poses an additional threat as shifting temperature and precipitation patterns may alter the specific microclimatic conditions required by this high-altitude specialist.

Threat summary

Habitat

Tarenna nilagirica is endemic to the montane forests of the Nilgiri Hills in the Western Ghats, typically found in moist deciduous and semi-evergreen forests at elevations between 1,000-2,000 meters. The species thrives in the understory of these cloud-influenced forests, preferring areas with high humidity and well-drained soils characteristic of the region's unique shola-grassland ecosystem.
