02Description

Species Profile

Species profile data sourced from the IUCN Red List of Threatened Species.

Scented Oakfern faces severe threats from habitat destruction and fragmentation of its specialized limestone environments. Climate change poses additional risks by altering the cool, moist microclimate conditions this species requires, while human disturbance from quarrying and recreational activities further degrades its already limited suitable habitat.
