Overview

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

Small Bladderwort faces severe decline due to habitat degradation from agricultural runoff and eutrophication of its aquatic environments. Drainage of wetlands for development and intensive farming has eliminated many historical populations. Climate change-induced alterations to water chemistry and seasonal flooding patterns further threaten remaining colonies in shallow pools and bog margins.

Threat summary

Habitat

Small Bladderwort inhabits shallow, nutrient-poor acidic waters including bog pools, pond margins, ditches, and slow-moving streams. This carnivorous aquatic plant requires clean, soft water conditions with minimal nutrient loading to maintain its specialized trap-feeding mechanisms.
