Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Norfolk Skullcap faces severe threats from its extremely limited distribution on Norfolk Island, where habitat degradation from invasive plant species and historical land clearing have significantly reduced suitable growing areas. The species' small population size makes it highly vulnerable to stochastic events and genetic bottlenecks, while ongoing pressure from introduced weeds continues to degrade its remaining habitat.
Key Facts
Habitat & Distribution
Norfolk Skullcap occurs in coastal cliff areas, rocky outcrops, and remnant native vegetation on Norfolk Island. The species typically grows in well-drained soils among native shrublands and forest margins in exposed coastal environments.
