Reforestation and afforestation are fundamentally limited by the land area available, as trees can only hold a finite amount of carbon. We must also remember that reforestation is not always the best option, and this is why the term ‘rewilding’ is used in conjunction with reforestation. For example, draining wetlands or peatlands to plant forests is counter-productive, as the carbon storage will be lower and losses of biodiversity will be considerable.
