One of the real problems with tree planting is that humans don’t comprehend the lifetime of a tree intuitively - hence chopping down a heritage tree and replacing with 10 saplings. It takes a couple of centuries for a tree to reach full maturity. At 100 years they’re adolescent. Combine this with our lack of appreciation for the “network effects” of forests and we are exceptionally neglectful of these incredible life forms.

Highly, highly recommend the book The Hidden Life of Trees
