Ctenitis grisebachii

Unknown

Overview

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

Ctenitis grisebachii faces severe threats from habitat destruction due to agricultural expansion and urban development in its limited Caribbean range. The species' restricted distribution makes it extremely vulnerable to localized disturbances, while climate change poses additional risks through altered precipitation patterns affecting the moist forest conditions it requires. Invasive plant species further threaten native understory communities where this fern persists.

Threat summary

Habitat

This critically endangered fern inhabits moist tropical forests and shaded understory environments in the Caribbean region. It typically grows in humid, well-drained soils under forest canopy where it benefits from consistent moisture and filtered sunlight.
