Isonandra stocksii

Unknown

Overview

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

Isonandra stocksii faces severe pressure from deforestation and habitat fragmentation across its Western Ghats range, where lowland forests are being cleared for agriculture, plantations, and urban development. The species' valuable timber has led to selective logging pressure, while its restricted distribution makes remaining populations highly vulnerable to local extinctions. Climate change poses an additional threat by altering the moisture regimes essential for this tropical tree species.

Threat summary

Habitat

Isonandra stocksii occurs in tropical evergreen and semi-evergreen forests of the Western Ghats, typically in lowland and mid-elevation areas with high rainfall and humidity. The species thrives in dense forest canopies where it can reach emergent status, requiring well-drained soils and consistent moisture throughout the year.
