Why would tee screens be needed more than green screens or fairway screens? Its possible to be hit in many places on the course, its a risk one accepts by playing (some courses more than others)
Usually trees serve the required purpose, I'd rather see a row of evergreens than a screen. Probably planting semi-mature evergreens 8'-10' high would not cost much more that a fence, and look a lot better. The thick ones will knock down any ball that comes their way, and as a bonus will provide a lost ball or unplayable penalty to the offender making them want to keep away from that tee in the future!
