Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Piedmont bladderwort faces severe threats from habitat destruction due to wetland drainage, development, and agricultural conversion of its specialized bog and seepage habitats. The species' extremely limited range and specific ecological requirements make it highly vulnerable to environmental changes and human disturbance. Climate change and altered hydrology further threaten the delicate water balance these carnivorous plants require for survival.
Key Facts
Habitat & Distribution
Piedmont bladderwort inhabits acidic bogs, seepage areas, and shallow pools in the southeastern United States Piedmont region. This carnivorous plant requires nutrient-poor, permanently moist to seasonally flooded soils with specific pH and mineral conditions.
