How do you ensure your restoration project will be resilient in times of changing climate and increased fragmentation across the landscape? Tein McDonald discusses with Linda Broadhurst the implications of population size, the parental gene pool and the significance of pollinators in ensuring genetic diversity and countering inbreeding depression. In this expanding field, the importance of rigorous experimental designs and protocols is highlighted to ensure that trials undertaken today have relevance in the future. A great overview of the changing understanding of ‘provenance’ and its implication for on-ground practitioners.
