Polystichum kenwoodii
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Polystichum kenwoodii faces severe threats from habitat destruction due to urban development and recreational activities in its limited range. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while invasive plant species compete for resources in its specialized habitat. Climate change poses additional risks through altered precipitation patterns that could affect the moist conditions this fern requires.
Habitat
This rare fern inhabits moist, shaded rocky outcrops and cliff faces in forested areas of the Pacific Northwest. It typically grows in crevices and ledges where it can access consistent moisture while remaining protected from direct sunlight.
