Hi Richard:
They should be fine as most naturally occurring hardwood trees have been browsed at one point during their life cycle from seedling, to sapling, to mature tree.
The use of tree shelters/tubes is obviously one approach for smaller numbers of transplants. For large-scale reforestation projects, I simply recommend overplanting (i.e., higher density of seedlings per acre) in order to overcome the high likelihood of deer browsing damage.
Best of luck!
