Psychotria gagneorum
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Psychotria gagneorum faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited Hawaiian range. Invasive plant species compete directly with this endemic coffee family shrub, altering forest composition and reducing available growing space. The species' extremely restricted distribution makes it particularly vulnerable to stochastic events and localized disturbances that could eliminate entire populations.
Habitat
This endemic Hawaiian shrub inhabits mesic to wet native forests on volcanic slopes, typically growing in understory conditions beneath native canopy trees. It requires well-drained soils and specific moisture conditions found in mid-elevation forest ecosystems between 300-800 meters elevation.
