New strategies needed to preserve kauri, t?tara seeds

From Nights, 9:30 pm on 12 December 2023

Many of Aotearoa New Zealand's iconic tree species are threatened with extinction and a new study says the traditional ways of preserving seeds might not work for all of them. The research has found about 1 in 5 native species, including forest giants like kauri, totara and rimu, can't be reliably preserved using conventional seedbanking techniques. Currently, little is known about how to perfect more complicated techniqes, such as cryopreservation, among these taonga species. Lead researcher Dr Sarah Wyse from the School of Forestry at Te Whare Wananga o Waitaha - University of Canterbury joins the programme.
