Elaphoglossum marquisearum

Unknown

Overview

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

Elaphoglossum marquisearum faces severe pressure from habitat degradation across its limited range in the Marquesas Islands. The species is particularly vulnerable to invasive plant species that alter the understory composition of its native forest habitats. Climate change poses an additional threat through altered precipitation patterns that could affect the humid microclimates essential for this epiphytic fern's survival.
