Place attachment and attitudes to landscape change for tree planting and net zero

open access: yesPeople and Nature, EarlyView.
Abstract To reach net zero by 2050 the Paris Agreement on Climate Change recommended tree cover expansion and tree planting to support Nationally Determined Contributions. We use place attachment in the context of historical events to explore landscape change and attitudes towards tree planting.
