Heliotropium perlmanii

Declining

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.

Threat summary

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.

Why is Heliotropium perlmanii classified as Endangered?
Heliotropium perlmanii is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. 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.
Where does Heliotropium perlmanii live?
