Eriocaulon rouxianum

Declining

Overview

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

Eriocaulon rouxianum faces severe threats from habitat destruction due to urban development and agricultural expansion in its limited range. The species is particularly vulnerable to water pollution and changes in hydrology that affect the seasonal wetlands it depends upon. Mining activities and infrastructure development have further fragmented its already restricted habitat, while climate change threatens to alter the precipitation patterns essential for its survival.
