Overview

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

The Tiny Mousetail faces severe decline due to agricultural intensification and conversion of its specialized wetland habitats. Drainage of seasonal pools and wet meadows for crop production has eliminated much of its historical range, while herbicide use and altered flooding regimes in remaining sites prevent successful reproduction. Climate change compounds these pressures by altering precipitation patterns that the species depends on for its annual lifecycle.

Threat summary

Habitat

Tiny Mousetail inhabits seasonal pools, wet meadows, and temporarily flooded grasslands, particularly in areas with clay or alkaline soils. The species requires specific moisture conditions during its growing season, thriving in shallow water that gradually recedes as the plant matures.
