Kadua grantii
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Kadua grantii faces severe threats from invasive plant species that outcompete this endemic Hawaiian shrub for resources and habitat space. Habitat degradation from feral ungulates, particularly pigs and goats, has destroyed much of its native dry forest ecosystem. Urban development and agricultural expansion have further reduced its already limited range on the Hawaiian islands.
Habitat
Kadua grantii inhabits dry to mesic forests and shrublands in the Hawaiian Islands, typically growing in rocky or volcanic soils at elevations between 300-1,200 meters. This endemic species is adapted to the unique microclimatic conditions of Hawaiian dry forest ecosystems.
