Hawai’i Volcanoes National Park
The intriguing story of plants within the Park includes a host of chapters such as the extreme isolation of the Hawaiian Archipelago, the processes by which flora and fauna arrived and developed and the influences of lava flows of varying age, texture and chemical composition. Moisture brought by prevailing trade winds delivers extreme differences in annual rainfall— varying from 20 inches on the coast to more than 144 inches at mid-elevation windward areas. Acid rain from the eruptions of Kilauea Volcano paints chemical deserts across miles of lava flows within the Park as ongoing lava flows form new landscapes. Together, all these influences create a remarkable mix of habitats in seven ecological life zones, stretching from sea level to the summit of Mauna Loa at 13,677’ in elevation.
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 in terms of time and funds towards removal of alien ungulates such as mouflon sheep, removal of the most displacing invasive plants, planting of endangered plant populations and large-scale planting of natives in Park landscapes that have been disturbed by ungulates or wildfire.

Did You Know?
The two types of Hawaiian lava differ in appearance but are chemically alike. Pahoehoe has a smoother and ropey surface where a`a is jagged and clinkery.
