The million dollar question of ‘provenance’ is eloquently described by Linda Broadhurst within the context of habitat fragmentation and climate change impacts. The talk simply explains the role of genetics in understanding inbreeding depressions and how they can arise from small population sizes or reduced parental numbers. A must see video for anyone who collects or propagates seed for restoration projects.
