My favorite screening cover is light, so it's almost never a bad thing to open it up, sometimes it's just a short term sacrifice which can be tough or non negotiable on micro properties. Still takes a few years for stuff to grow deer high, but if you can drop some junk trees with bigger tops that can really help things along in that regard. I don't even attempt to look at maps for habitat work, have to see how everything flows in person. If you're in a planting mood, I love planting stuff that stays green all year for deer cover. Pines, rhodendrons, laurels, cedars, you can really direct traffic. Just keep them in succession because once they get above cover height, they're just shade/junk.
