Pascua sticta
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pascua sticta faces severe threats from habitat degradation on Easter Island, where introduced grazing animals and invasive plant species have dramatically altered the native vegetation communities. The species' extremely limited range makes it particularly vulnerable to stochastic events and ongoing environmental changes. Overgrazing by cattle and horses continues to degrade the remaining suitable habitat patches.
Habitat
This lichen species is endemic to Easter Island (Rapa Nui), where it occurs in the island's limited native vegetation remnants. It typically grows on volcanic substrates in areas with minimal human disturbance.
