Recovery Plan for the Mauna Kea Silversword (Argyroxiphium sandwicense ssp. sandwicense) F 1 Pacific Islands Fish and Wildlife Office (808) 792-9400 `Ahinahina Argyroxiphium sandwicense ssp. sandwicense 1 11 Search for unknown populations on Mauna Kea Complete Prior to FY 1995 FY 2000 - FY 2004 U.S. Fish and Wildlife Service U.S. Fish and Wildlife Service, Ecological Services Division, University of Hawaii, Hawaii Department of Land and Natural Resources Research: Population Surveys Species Expert The Hawaiian Silversword Foundation and other partners in the informal silversword working group have completed many hours of surveys for additional populations in the late 1990s, and found a few new plants in Waipahoehoe and Wailuku drainages. ES was not the lead for this task, even though it was originally designated so.

Currently, DNLR conducts periodic aerial hunts which keep the numbers low, but do not entirely eliminate the sheep.

A new population found in 2008 in Pohakuloa Gulch is in the process of being fenced.

Complete FY 1995 - FY 1999 FY 1995 - FY 1999 Other University of Hawaii, Hawaii Department of Land and Natural Resources, U.S. Geological Survey, Biological Resources Division Research: Habitat Requirements Contract The Hawaiian Silversword Foundation, from years of visits to the sites to monitor and hand pollinate plants, have determined that the species of the native solitary Hylaeus bee genus are the pollinators of this subspecies. Nonnative honey bees (Apis melifera) visit the flowers but appear to steal pollen rather than move it between plants. Microsatellite genetic studies have been done (Conservation Biology 11: 1190-1146)showing that the population outplanted in the 1970s from two indivdiuals, now totaling over 800 individuals, has only 25% of the genetic diversity of the ca 50 wild individuals alive at the time of the study.

No seed is left in the wild at this time, as the wild population is declining rapidly (approximately two individuals are lost every year prior to reproducing) and the seed is too valuable to leave to chance germination and establishment in the field. Controlled propagation is used to reintroduce seedlings, since previous outplantings have an 80+% survivorship.

In 1996, two wild individuals flowered and over 3,000 individuals have been reintroduced with 80+% survivorship. No additional flowering occurred until 2005, and in Sepember 2005 100,000 seeds were collected from hand pollinated crosses of the wild individual with several outplanted individuals. These seeds will be propagated at Volcano Rare Plant Facility and outplanted in the fall of 2006. No more individuals can then be added to the reintroduced populations until more wild individuals flower. The goal is to increase the founder representation to at least 10 parents, and with the 2005 seeds we will have 5 founders.

At that point, the likelihood of success of the reintroduction effort will be better understood, and numbers of individuals needed can be adjusted based on reproductive success.
