Faya was brought to Hawaii for its berries and later used in reforestation

Faya, originally introduced to Hawaii for its berries and later used in reforestation, has become an invasive species in Hawaii Volcanoes National Park. This tree disrupts the native ecosystem by altering soil pH and shading native plants. Birds play a crucial role in spreading Faya's berries, furthering its invasion. Control efforts include girdling the trees and applying herbicide to manage its spread.
