Overview

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

The Roundleaf Sundew faces severe population declines primarily due to wetland habitat destruction and drainage for agricultural conversion and urban development. Peat bog extraction and commercial harvesting have eliminated entire populations across its range, while climate change is altering the delicate moisture balance these carnivorous plants require. Pollution from agricultural runoff and atmospheric nitrogen deposition disrupts the nutrient-poor conditions essential for sundew survival.

Threat summary

Habitat

Roundleaf Sundew inhabits nutrient-poor, acidic wetlands including sphagnum bogs, fens, wet heathlands, and marshy areas with consistently moist soils. These carnivorous plants require open, sunny locations with minimal competition from other vegetation and depend on the specialized conditions found in peat-based ecosystems.
