Clermont'S Spleenwort

Clermont's Spleenwort, Asplenium clermontiae, is a small fern in the family Aspleniaceae with a very restricted distribution in the Indian Ocean islands, believed to occur in the Mascarene archipelago. The genus Asplenium, the spleenworts, is one of the largest and most diverse fern genera globally, with species adapted to rock faces, tree bark, and moist forest floors across tropical, subtropical, and temperate regions. Clermont's Spleenwort, like many island-endemic Asplenium species, likely grows epiphytically on tree trunks or lithophytically on humid rock faces in montane forest, protected from the desiccating conditions of lower elevations. Island endemic ferns in the Mascarenes face severe threats from habitat loss driven by agricultural conversion, invasive plant species that alter forest structure, and introduced herbivores that destroy forest understory vegetation. Many spleenwort species have very small total populations confined to remnant forest patches. Asplenium clermontiae is considered rare and potentially threatened, though formal assessment data on its exact population size and trend are limited. Conservation of the species depends on the protection and restoration of humid forest habitats on the islands where it occurs.
