Has your department looked into cottonwood planting for such areas? In Oregon
this are exactly the sites targeted. And the hybrid cottonwood are being
mass- grown for pulp, which is harvested in 7-12 years. Seven year old
cottonwood are approximately 75 feet tall and about 10 inches diameter at the
base. 12 year old material exceeds 15 inches diameter. At a local Clackamas
County farm this material is being cut down for firewood, and grows a wide
variety of fungi, including Morchella (symbiotic with cottonwood, BTW),
Pleurotus (better known as oyster), Goat's Beard or Bear's Head (Hericium
erinaceus); and probably is suitable for other fungi as well. Interestingly,
the stumps are the easiest biomass to inoculate with this fungus. And the
trees are grown by simply shoving an 18-24 inch whip into the ground in
January-February. Pretty easy silviculture practice, I'd say.
