Nellie Sugii in the Micropropagation Lab

Lyon Arboretum researcher honored as Endangered Species Recovery Champion

Nellie Sugii, manager of the University of Hawaiʻi Harold L. Lyon Arboretum’s Hawaiian Rare Plant Program (HRPP) was honored with a 2016 U.S. Fish and Wildlife Service Recovery Champion award. This highly prestigious award is given to select U.S. Fish and Wildlife Service staff and partners whose leadership efforts are integral to the recovery of endangered and threatened species of plants and animals. Sugii’s 30 years of experience has led to the development of methods to propagate Hawaiʻi’s most endangered plants via tissue culture and other techniques, many of which may have gone extinct without her efforts.

Asplenium peruvianum var. insulare

Sugii was chosen because of her outstanding dedication to the program and numerous accomplishments. She has maintained and expanded the HRPP on highly competitive grants for nearly 20 years and is a recognized leader in the broader plant conservation community in the Hawaiʻi Rare Plant Restoration Group, Laukahi Plant Conservation Network, and in the International Union for Conservation of Nature Red List Specialist Group. She mentors dozens of staff, UH students, and volunteers and is known internationally for her expertise in micropropagation of rare species.


Although Hawaiʻi makes up only 0.2 percent of the land mass of the United States, more than quarter of the species on the endangered species list are found only in Hawaiʻi, and most of them are plants. Under Sugii’s leadership, the HRPP plays an important role in preventing the extinction of Hawaiʻi’s most critically endangered plants, using micropropagation techniques (growing tiny plants in test tubes) as well as seeds collected from these plants for banking. Many of the plants in the lab are difficult to propagate due to the low viability of the seeds or not producing seeds at all. The plants sheltered in the lab represent a broad range of Hawaiian species not limited to one region or area in the Hawaiian Islands. Her efforts have led to the propagation of more than 500 of the 1300 taxa of native Hawaiian plants.

About the Hawaiian Rare Plant Program

The HRPP is often the last chance for many of Hawaiʻi’s endangered endemic plants to survive. The laboratory serves as a rescue, recovery and storage unit for the conservation of critically endangered Hawaiian plants and is the only one of its kind in Hawaiʻi. Since 1993, tens of thousands of native plants have been maintained in the lab collections. Currently, there are about 250 native species in the collection, some of which no longer occur in the wild. HRPP is recognized internationally for its research and leadership in this area.
