Paspalum rugulosum

Unknown

Overview

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

Paspalum rugulosum faces severe pressure from agricultural expansion and cattle ranching across its native grassland habitats in South America. Urban development and infrastructure projects have fragmented remaining populations, while invasive grass species compete directly for resources. Climate change is altering precipitation patterns in the region, affecting the seasonal flooding cycles that this species depends on for reproduction.
