In the Seed Lab, over 16 million seeds are banked, representing more than 550 taxa of native Hawaiian plants, or about 40% of the flora. Of these, over half are federally listed as endangered. The Seed Lab partners with Lyon’s Micropropagation Lab, the Plant Extinction Prevention Program (PEPP), the Department of Forestry and Wildlife (DOFAW), and other agencies to provide for both long-term storage – preservation of genetic diversity – and propagation of plants for restoration efforts. We also conduct original research on seed characteristics such as storage behavior, longevity, dormancy, and germination.
Lyon’s Seed Conservation Lab also spearheaded efforts to bank seeds of ʻōhiʻa during the Rapid ʻŌhiʻa Death crisis, including the #OhiaLove Campaign (2016-2017) and the ROD Seed Banking Initiative (2017-2018). We’ve already collected and banked over 2 million seeds and are now scaling up the efforts across all islands, which includes an ʻōhiʻa seed collection workshop series in fall 2017, open to all.

Prior to the establishment of the Seed Conservation Lab in 1995, little was known about how well seeds of native Hawaiian plant species might be stored. It is estimated that worldwide, about 20% of seeds are recalcitrant, meaning that they are desiccation-sensitive and cannot be stored long-term. However, with our current knowledge, only about 6% of Hawaiian taxa have recalcitrant seeds – great news for our seed banking efforts. On the other hand, many Hawaiian seeds face other challenges with long-term storage.
We continue to conduct research on our existing collections, testing viability under different conditions at various intervals over the years, and we have data for some species that have been stored for 20 years. We have added several species of ferns to our collection and are beginning to study spore storage potential. We also continually seek to make collections of seeds for research on species that we do not understand as well yet. The Hawaiian flora continues to surprise us with new discoveries in seed characteristics and behavior!
Facilitating UH Research
The Seed Lab generates many native plant seedlings through our regular germination testing. While many of these are propagated for rare plant restoration efforts, we also do generate seedlings of more common species or other species that are not set aside for restoration. In the near future we hope to provide a continually updating list of upcoming seedlings that could be used by UH faculty and students for research. In the meantime, please contact us if you are interested in learning more.
