In this webinar, we present the findings of the TreE PlaNat project, examining the socio-ecological consequences of woodland expansion through planting and natural colonisation. We share new ecological and social research findings, the outcomes of our knowledge exchange activities, and perspectives on natural colonisation and involvement in the project from project partners (Woodland Trust and National Forest Company) and contributors Stump up for Trees, South Yorkshire Woodland Partnership and Natural England. There are approximately 45 minutes of presentations, with around 20 minutes of a practitioner panel discussion, followed by a Q&A.
