Overview

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

The Pale Bladderwort faces severe decline due to habitat destruction from peat bog drainage and agricultural conversion of wetlands. Climate change poses an additional threat by altering the hydrology of its specialized bog ecosystems, while eutrophication from agricultural runoff degrades water quality in remaining habitats. The species' highly specific ecological requirements make it particularly vulnerable to even minor environmental changes.

Threat summary

Habitat

This carnivorous aquatic plant inhabits acidic, nutrient-poor waters of sphagnum bogs, fens, and shallow pools in peatland ecosystems. It requires very specific water chemistry conditions with low pH and minimal nutrient levels, typically found in undisturbed boreal and temperate wetland complexes.

Why is Pale Bladderwort classified as Endangered?
Pale Bladderwort is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. The Pale Bladderwort faces severe decline due to habitat destruction from peat bog drainage and agricultural conversion of wetlands. Climate change poses an additional threat by altering the hydrology of its specialized bog ecosystems, while eutrophication from agricultural runoff degrades water quality in remaining habitats. The species' highly specific ecological requirements make it particularly vulnerable to even minor environmental changes.
Where does Pale Bladderwort live?
