May 4: Native Hawaiian Fern Propagation and Restoration

Often overlooked, ferns are a critical part of the ecosystem on islands and have many cultural uses. NTBG is one of a few gardens having specialized in propagation of rare Hawaiian ferns from spores.

April 13: Conservation and Restoration of Endangered Trees

In this session we celebrate some of the great conservation and restoration projects. NTBG’s Director of Science and Conservation Nina Ronsted and Uma Nagendra will talk about how NTBG is translating global tree assessments to restoration of threatened plant species in Limahuli Valley. University of Hawaii graduate student assistant Julia Douglas report from a recent field campaign monitoring NTBG’s successful outplanting of Critically Endangered Polyscias bisattenuata and NTBG’s Director of Kahanu Garden, Mike Opgenorth will share his PhD work on conservation of Gardenia remyi.

Meet Noel Dickinson, Coordinator of the Breadfruit Institute for an update on the developments of the Regenerative Organic Breadfruit Agroforest in our McBryde Garden, and Elliot Gardner, our joint postdoc between NTBG and the International Center for Tropical Botany, who will talk about new ulu discoveries and what we know about the relationships of the different species. Carl Holmquist Andersen and Emile Hansted Berning reports on a survey of the contribution of breadfruit agroecosystems to Hawaiian community resilience during the COVID – 19 pandemic.

February 23: Controlling Invasive Species

In honor of Hawaii Invasive Species Month, our staff discussed the good and bad side of bringing plants beyond their natural habitat. Meet Curator of Living Collections Mike DeMotta and Director of Kahanu Garden Mike Opgenorth to find out how we fight against invasive species throughout our gardens and in the field and how Master of Science student John Steinhorst is on a mission to propagate native Hawaiian plants for the horticulture trade.
