Detailed counts of all size and age classes are not conducted, however, because the bog habitat is extremely fragile and it is difficult to see young plants within the bog, making the trampling impacts from monitoring too risky. In 2012, there were approx. 200-300 plants in the remnant population.

At these sites, Axonopus fissifolius and Carex sp. are being controlled. Alien plant threats at the other sites are assessed when silversword populations are monitored, and if any appear to be threats, additional research and/or management actions will be taken.

The areas within Hawaii Volcanoes National Park do not require posted signs, as the park has many signs throughout discouraging damage to native vegetation and geological features. The value of warning signs has been brought into question in Hawaii, as other posted populations have encouraged rather than discouraged vandalism.

This information has been incorporated into the reintroduction efforts for this species by maintaining the genetic distinctness of the different habitat preferences.

In 2003, propagated individuals were infested with fungus, and so were destroyed rather than reintroduced. A native tephritid insect eats the seeds, but does not appear to reduce the seed supply significantly. All sites are monitored for ants, which prey on the solitary bees that pollinate the silversword.

Many plants in unfenced areas remain in the juvenile size class for years or even decades before dying without flowering. The causes are most likely predation by feral ungulates and/or establishment in poor quality sites with not enough soil for full growth and reproduction. While no detailed experimental research is occurring, monitoring of wild and outplanted populations provides a great deal of information that enhances future reintroduction efforts.

In addition, material is grown in the Volcano Rare Plant Facility from wild collected seeds or cuttings to use as a managed breeding population, allowing the production of more seed. Only 1st generation seedlings are used for reintroductions.

One exception is one reintroductions into Kulani pocket bogs, which flooded and killed many of the outplants. Plants are now put into microsites further away from the edge of the pocket bogs. The only other exception is the use of Waiakea source material for reintroduction into a more dry habitat on Mauna Loa Strip in Hawaii Volcanoes National Park. The plants did not grow well, and were subsequently destroyed when one mouflon sheep got into the fenced area. Since then, Kapapala source material was found and has been used at this reintroduction site with much greater success. As of 2012, a total of 25,246 seedlings have been outplanted across the 6 main sites in Hawaii Volcano National Park, State forest reserves and Natural area reserves.

Volunteers from the correctional facility, local schools, and the local community are recruited for reintroduction efforts, and so learn about the recovery efforts. Additional efforts to reach the general public are still needed, as well as scientific articles to share the reasons for success of what is probably the largest single species reintroduction effort in the country.
Recovery Plan for the Ka`u Silversword (Argyroxiphium kauense) F 1 Pacific Islands Fish and Wildlife Office (808) 792-9400 Mauna Loa (=Ka'u) silversword Argyroxiphium kauense 3 51 Estimate # of plants & populations needed for long term survival Ongoing Current FY 2000 - FY 2004 U.S. Fish and Wildlife Service U.S. Fish and Wildlife Service, Ecological Services Division, Division of Forestry and Wildlife, Hawaii Department of Land and Natural Resources, U.S. Geological Survey, Biological Resources Division Management: Planning Internal Administrative The true success of this large reintroduction effort will not be known until planted individuals flower and produce viable seeds that become established naturally. In the meantime, the results of current efforts lead the species experts to believe that downlisting will be possible when 10 populations (sustainable recovery for each source population, since in very different habitats and the three sources populations are genetically divergent based on micro-satellite data), with 2,500-3,000 reproductive-sized individuals in each population (self-incompatible, monocarpic, and long-lived) are sustained over 25 years (second generation recruitment in reintroduced plants expected); and management maintained in perpetuity or until no longer necessary.

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.
