Overview

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

Wild Celery faces severe threats from habitat degradation due to water pollution, eutrophication, and sedimentation in freshwater systems. Invasive species competition, dam construction altering water flow patterns, and climate change impacts on water temperature and chemistry have contributed to significant population declines across its range.

Threat summary

Habitat

Shallow freshwater lakes, ponds, slow-moving rivers, and coastal marshes with soft sediments, typically in waters 1-3 meters deep. Requires clear water with adequate light penetration for photosynthesis and prefers areas with gentle currents and stable water levels.

Frequently asked questions

Why is Wild Celery classified as Critically Endangered?
Wild Celery 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. Wild Celery faces severe threats from habitat degradation due to water pollution, eutrophication, and sedimentation in freshwater systems. Invasive species competition, dam construction altering water flow patterns, and climate change impacts on water temperature and chemistry have contributed to significant population declines across its range.
Where does Wild Celery live?
Wild Celery occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Wild Celery?
The main threats to Wild Celery are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
