This is a great article, and a huge issue in reclamation. Not like viable seed grows on trees... Wait. Fuck. We cut down the trees...
I've been part of major seed collection programs - it's a slow process, but important. Trying to maintain genetic integrity for species in the region is also something that was considered, and as such we were only allowed to harvest from certain locations and needed a certain amount of each species at each location.
Planning disturbance and acknowledging the implications of the disturbance need to be at the forefront of our minds. You don't get a 250 year old forest in any less time than 250 years, yet it only takes a day to clear it.
