Scale. A few years back. A large parcel (2 square hectares) of cottonwood poplar were ‘harvested’. The were planted to provide pallet wood. Whilst some trees (dark centres) are near the natural end of of the lifespan, many weren’t. I was employed by the small group that did this. I had no idea that this was deliberate. I was gobsmacked, angry. And it was one of the contributing reasons to resigning from forestry. 60yo crop. #Peupliers #Cottonwoods
