To regrow forests the U.S. needs billions of seeds–and many more 'seed hunters'
This seems like a short term fix prone to all the problems of mono-culture.  First pine-beetle infestations brining in disease put all that hard-work to naught.There is a natural progression to growing forests, how about protecting, and just staying off large swaths of land, using fire treatment and land management techniques as we understand them and let the land restore itself? Perhaps we have to think past 5-10 year windows and start to work at plans that think a minimum of 50 years out.  Old-growth forests take easily that long, at minimum, to get started "naturally".
