Finding this discussion to be very informative. So here's another question: is the paw paw in the citrus family? So it's a larval host plant for swallowtail? I grow wafer ash (hop trees) and get swallowtail larva on those.
And no, Ann, could not plant trees on the river bank. We get major floods where the water can rise 30 - 45 feet. It would be washed away. I've seen the current carry off full-grown pecan trees. Only the huge, old bald cypress trees survive.
In this photo, the trees in the background are the "river bank".
