Sadly, Hawai’i faces an ecological crisis. Plants that have survived for millennia now face tremendous threats from alien invasive plants and wildlife species, creating great challenges for resource managers. Within Hawai’i Volcanoes National Park are 23 species of endangered vascular plants including 15 species of endangered trees. The race to recover the park’s native landscapes and endangered plants is a major commitment of the Resources Management Division. The removal of alien ungulates such as mouflon sheep, removal of the most displacing invasive plants, and the planting of endangered and native plants are all priorities.
