Cottonwood is the perfect wood for stretch-fires!

They definitely do get their start in the wet areas. Around me, they and box elder seem to be the 'volunteer' species. But silver maple can do well in some of those low, wet areas as well. And some hickory, cherry, and oak. I'm more envisioning what I could do here with a bit more time and a few more acres...

Well, white ash can also do extremely well in those wet areas, but they are a dieing species. Another good one to find along creeks and fence rows are the elms. Hickory around here seem to prefer more drier areas or at least semi-dry. Cherry prefers dry here as do oaks.
