Rhynchospora hildebrandtii

Declining

Overview

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

Rhynchospora hildebrandtii faces severe threats from agricultural expansion and urban development across its limited range in East Africa. Wetland drainage for rice cultivation and infrastructure projects has eliminated much of its specialized sedge habitat. Climate change compounds these pressures by altering precipitation patterns critical for maintaining the seasonal water levels this species requires.

Threat summary

Habitat

This sedge species inhabits seasonal wetlands, marshy grasslands, and the margins of temporary pools in East African highlands. It requires specific hydrological conditions with seasonal flooding followed by gradual drying periods.
