Trapa colchica
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Trapa colchica faces severe population decline due to habitat destruction from wetland drainage and agricultural conversion throughout its native range in the Caucasus region. Water pollution from agricultural runoff and urban development has degraded remaining aquatic habitats, while climate change-induced alterations to precipitation patterns threaten the seasonal water levels this species requires for reproduction.
Habitat
Trapa colchica inhabits shallow freshwater lakes, ponds, and slow-moving rivers in the Caucasus region, typically growing in nutrient-rich waters with muddy substrates. The species requires specific seasonal water level fluctuations and prefers areas with partial shade from surrounding vegetation.
