Scleria guineensis

Declining

Overview

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

Scleria guineensis faces severe population decline primarily due to agricultural expansion and urban development across its West African range. Conversion of wetland habitats for rice cultivation and infrastructure development has eliminated critical breeding and feeding areas. Climate change-induced alterations to rainfall patterns threaten the seasonal flooding cycles essential for this sedge's reproductive success.

Threat summary

Habitat

This sedge species inhabits seasonal wetlands, marshy grasslands, and the margins of temporary pools in West African savannas. It requires areas with fluctuating water levels and thrives in nutrient-rich soils that experience periodic flooding during the rainy season.
