Native: Species naturally occurs in park or region. Plants: Abundance variable from year to year (e.g., desert plants).Animals: Occurs in the park at least once every few years, varying in numbers, but not necessarily every year.Plants: Few individuals, usually restricted to small areas of rare habitat.Animals: Present, but usually seen only a few times each year.Plants: Few to moderate numbers of individuals occurring either sporadically in commonly encountered habitats or in uncommon habitats.Animals: Likely to be seen monthly in appropriate habitat and season.Plants: Large numbers of individuals predictably occurring in commonly encountered habitats but not those covering a large portion of the park.Animals: May be seen daily, in suitable habitat and season, but not in large numbers.Plants: Large number of individuals wide ecological amplitude or occurring in habitats covering a large portion of the park.Animals: May be seen daily, in suitable habitat and season, and counted in relatively large numbers.Assigned based on judgment as opposed to determination based on age of the most recent evidence. Historical: Species' historical occurrence in park is documented. Not In Park: Species is not known to occur in park.Īdjacent: Species is known to occur in areas near to or contiguous with park boundaries.įalse Report: Species was reported to occur within the park, but current evidence indicates the report was based on misidentification, a taxonomic concept no longer accepted, or other similar problem of error or interpretation. Unconfirmed: Species is attributed to park but evidence is weak or absent. Probably Present: High confidence species occurs in park but current, verified evidence needed. Present: Species occurs in park current, reliable evidence available. One or more Occurrence Tags may be associated with each Occurrence value. 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. The race to recover the park’s native landscapes and endangered plants is a major commitment of the Resources Management Division. Within Hawai’i Volcanoes National Park are 23 species of endangered vascular plants including 15 species of endangered trees. Plants that have survived for millennia now face tremendous threats from alien invasive plants and wildlife species, creating great challenges for resource managers. Sadly, Hawai’i faces an ecological crisis. These are just a few of the amazing diversity of plants living within the park. Today, the national park harbors the descendents of those first colonizers-numerous evolutionary marvels such as mintless mints and nettleless nettles-plants adapted to life without plant-eating mammals. Evolving over 70 million years ago in nearly complete isolation, more than 90% of the state’s native flora are found only in the Hawaiian Islands. Miles above, the distinctive rosette of the endangered Mauna Loa silversword clings to an alpine ledge. At the park’s mid-elevation, blazing blooms of ʻōhiʻa trees and towering fronds of giant hāpu’u, a tree fern, rise amid a tangle of misty rain forest. Hawaiʻi Volcanoes National Park Harbors a Plant ParadiseĪlong the wind-scoured coastal plain, the lone tendrils of an ʻae fern peer from cracks in endless flows of hardened lava.
