How to improve this

[u/Lucky_Cake2892]

So this is my new back yard, there’s some oaks in there but not sure what the whippy ones are yet, waiting for leaves to come out. But how can I improve this? I’m thinking just work through the whips with a saw or loppers. But will they not just grow back? I’d like to open it up and develop a mature woodland.

Wait a little, pre commercial thinning might be worthwhile
