Heliotropium perlmanii
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Heliotropium perlmanii faces severe threats from habitat degradation caused by invasive plant species that outcompete this endemic Hawaiian shrub in its limited coastal range. Urban development and recreational activities along Oahu's coastline have further reduced available habitat, while the species' extremely restricted distribution makes it vulnerable to stochastic events. Climate change-induced sea level rise poses an additional long-term threat to its low-elevation coastal habitat.
Habitat
This endemic Hawaiian shrub occupies dry coastal shrublands and rocky outcrops along the shoreline of Oahu. It grows in harsh, salt-spray exposed environments with well-drained soils at low elevations near the ocean.
