Hydrostachys maximus

Unknown

Overview

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

Hydrostachys maximus faces significant pressure from dam construction and water regulation projects that alter the natural flow regimes essential for its survival. Agricultural expansion and urban development in watersheds increase sedimentation and nutrient pollution in the fast-flowing streams where this aquatic plant grows. Climate change poses an additional threat through altered precipitation patterns that could disrupt the specific hydrological conditions this species requires.

Threat summary

Habitat

This aquatic plant is endemic to fast-flowing, rocky streams and waterfalls in tropical regions, where it attaches to submerged rocks and boulders. It requires specific hydrological conditions with high oxygen levels and consistent water flow to complete its unique reproductive cycle.
