I wouldn’t touch the ash saplings. I don’t know how bad chalara is in your area but it will hit you. The ash will thin it’s self out eventually. It doesn’t look like the beech is dominating the woodland either which is a good thing for ground flora. As I’m not sure of what you want from the land yet it looks alright to me without any intervention.
Some times management by neglect is the best way. Just keep managing the path ways.
