Bolboschoenus grandispicus

Declining

Overview

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

Bolboschoenus grandispicus faces severe threats from wetland drainage and agricultural conversion throughout its limited range. Urban development and water diversion projects have eliminated many of the seasonal wetlands and marshy areas essential for this sedge's survival. Climate change compounds these pressures by altering precipitation patterns and increasing drought frequency in its already restricted habitat.

Threat summary

Habitat

This critically endangered sedge inhabits seasonal wetlands, marshy areas, and the margins of temporary pools in Mediterranean and semi-arid regions. It requires specific hydrological conditions with seasonal flooding followed by gradual drying periods.

Why is Bolboschoenus grandispicus classified as Critically Endangered?
Bolboschoenus grandispicus is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Bolboschoenus grandispicus faces severe threats from wetland drainage and agricultural conversion throughout its limited range. Urban development and water diversion projects have eliminated many of the seasonal wetlands and marshy areas essential for this sedge's survival. Climate change compounds these pressures by altering precipitation patterns and increasing drought frequency in its already restricted habitat.
Where does Bolboschoenus grandispicus live?
Bolboschoenus grandispicus occurs in Cape Verde, Guinea-Bissau, and Senegal. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Bolboschoenus grandispicus?
The main threats to Bolboschoenus grandispicus are 1.1, 5.3, 7.2, and ai-1. The full IUCN-classified threat record for this species is detailed on the species page.
