ArbNet Accredited Lyon Arboretum's Conservation Efforts

The Hawaiian Rare Plant Program laboratory has successfully grown approximately 300 of the 1,400 known Hawaiian plant taxa using micropropagation techniques.

The University of Hawaiʻi at Mānoa Lyon Arboretum’s efforts to protect threatened native plant species serve as a model for other areas of conservation concern.

The Hawaiian Rare Plant Program (HRPP), which started in 1992, utilizes multiple strategies including maintaining seed banks, conducting plant tissue culture, housing small greenhouses and maintaining living plant collections, all on the arboretum’s grounds. These techniques were recently featured in an article published in the journal Biological Conservation.
