Subject:

Plant conservation Plants Hawaii Island

Summary:

This recovery plan deals with 26 Hawaiian plant taxa that are, or were, widely distributed across the island chain such as the: Achyranthes mutica (no common name [NCN]), Adenophorus periens (pendant kihi fern), Bonamia menziesii (NCN), Cenchrus agrimonioides (kamanomano), Centaurium sebaeoides (awiwi), Cyanea grimesiana ssp. grimesiana (haha), Cyperus trachysanthos (pu uka a), Diellia erecta (NCN), Euphorbia haeleeleana (NCN), Flueggea neowawraea (mehamehame), Hibiscus brackenridgei (mao hau hele), Isodendroin laurifolium (aupaka), Isodendrion longifolium (aupaka), Mariscus pennatiformis (NCN), Neraudia sericea (maaloa), Panicum niihauense (lau ehu), Phyllostegia parviflora (NCN), Plantago priceps (ale), Plantanthera holochila (NCN), Sanicula purpurea (NCN), Schiedea hookeri (NCN), Schiedea nuttalii (NCN), Sesbania tomentosa (ohai), Solanum incompletum (thorny popolo), Spermolepis hawaiiensis (NCN), and the Vigna o-wahuensis (Oahu vigna). These 26 taxa (referred to as the "Multi-island plants") are found on 1 or more of the following Hawaiian Islands: Laysan, Necker, Nihoa, Niihau, Kauai, Oahu, Molokai, Lanai, Kahoolawe, Maui, and Hawaii. Immediate action must be taken to stabilize the remaining wild populations of these Multi-island plants. These actions include the propagation and maintenance of genetic stock ex situ, the management of fencing and/or hunting, (to control feral ungulates), the control of alien plants, rodents, damaging insects, slugs, and snails, the protection from fire, human disturbance, disease, (if necessary), as well as a comprehensive monitoring program. A research program is also recommended to study the growth and reproductive viability of each taxon, determine the parameters of viable populations of each taxon, study the reproductive strategy and pollinators of each taxon, and study possible pests and diseases. To ultimately recover the listed plant taxa in Hawaii, habitat must be protected and managed for natural expansion of the populations, as well as for the reintroduction of these taxa into portions of their former range. The recovery objective should also be refined and revised as new information becomes available.
