limestone spleenwort

Asplenium verecundum

Unknown

Overview

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

The limestone spleenwort faces severe pressure from quarrying and mining activities that destroy its specialized limestone cliff habitats. Urban development and infrastructure projects continue to fragment the remaining suitable rock face environments where this fern can establish. Climate change poses an additional threat through altered precipitation patterns that affect the moisture-dependent reproductive cycles of this endemic species.

Threat summary
