Shagbark Hickory

I think this shagbark hickory may eventually fall over, sooner if a really bad windstorm, perhaps. If I can slow down the erosion, should let it remain a long time, another 100 years? The left side needs some erosion control plants. Even in winter with no leaves, this area loses sun by noon. In the summer, full shade.
