Seed Bank Curator and Laboratory Manager
Seed Bank Curator and Laboratory Manager Dustin Wolkis is responsible for curating NTBGs seed bank and conducting seed conservation research. Dustin holds an MSc in Plant Biology and Conservation from Arizona State University and is currently pursuing a PhD degree at the University of Copenhagen, Denmark, focused on changing the seed banking paradigm using Hawaiian lobeliads as a model system. Dustin is also Deputy Chair of the IUCN SSC Seed Conservation Specialist Group.
Volunteers, interns, and students are providing critical help with all aspects of the Seed Bank.
Full of passion for conserving the natural world, Emily Saling comes to the Seed Lab as a Kupu Member and recent graduate in Biology from the University of Puget Sound. She draws on her past experiences working in museums and botanical gardens and on lichens as a pollutant bioindicator. Emily is excited to dive into seed conservation research and has already become an invaluable member of the Seed Bank and Laboratory team.
All seed collections are recorded in our databases, so we always know where any collection came from. It is important to collect the seeds at the right time when they are fully developed and ready to disperse.
Before seeds can be stored in the seed bank they need to be cleaned from fruit, a laborious work that take many hours for our dedicated volunteers.
To enable long-term storage seeds are kept at -18°C degrees. However, seed storage behavior and longevity varies greatly among and within species and understanding of seed behavior is critical for successful seed banking and conservation. NTBG conducts research and develops specific protocols ensuring optimal conditions for each of the over 500 species currently in the seed bank.
Once the seeds can be safely stored, it is critical to conduct viability studies to follow the germination success over time and know when seeds need to be propagated and resampled or new collections need to be made if possible. For each collection or accession, small samples are tested at regular intervals of 0, 1, 2, 5, 10 and every ten years after. The goal is for all seed collections to have at least 70% of their initial viability. All these data from over 30 years of seed banking can also be used to understand general trends and better prediction of storage behavior and viability of species where little is known. NTBGs seed work is planting new seeds of hope for Hawaii’s many rare and endangered plants.
