Overview

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

Small-flowered Bittercress faces severe population declines primarily due to habitat destruction from agricultural intensification and urban development across its limited range. The species' specialized requirements for moist, nutrient-poor soils in ephemeral wetlands make it particularly vulnerable to drainage and land conversion. Climate change compounds these pressures by altering precipitation patterns and increasing drought frequency in its already restricted habitat zones.

Threat summary

Habitat

Small-flowered Bittercress inhabits moist, sandy or muddy soils in temporary pools, seasonal wetlands, and disturbed ground near water sources. The species typically occurs in nutrient-poor substrates along pond margins, vernal pools, and occasionally in damp agricultural fields or construction sites with appropriate moisture conditions.
