  • The primary goal of this project is large-scale reintroduction of endangered silverswords (Argyroxiphium kauense) on Hawaii Island. Since 2007, more than 32,000 seedlings of the Mauna Loa silversword have been reintroduced into managed landscapes, with an overall survival rate of over 70 percent. Over the past two years, approximately three dozen reintroduced individuals have flowered and produced viable seeds. In addition, well over 1,000,000 seeds were collected and hand-broadcast into suitable microsites. This is likely the largest endangered species reintroduction effort in the United States.
