Scaevola marquesensis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Scaevola marquesensis faces severe threats from invasive plant species that outcompete native vegetation and alter ecosystem dynamics across its limited range in the Marquesas Islands. Habitat degradation from introduced ungulates, particularly goats and pigs, has damaged the coastal and lowland forest environments where this endemic shrub naturally occurs. The species' extremely restricted distribution makes it highly vulnerable to stochastic events and climate change impacts, including altered precipitation patterns and increased storm intensity.
Habitat
Scaevola marquesensis inhabits coastal areas and lowland dry forests of the Marquesas Islands, typically growing on rocky slopes and cliff faces at elevations up to 300 meters. The species is adapted to the archipelago's tropical oceanic climate with distinct wet and dry seasons.
