There are some good options. I’ve done a fair bit of research, already, looking for native plants that do well in dry soil and that are resistant to deer browse since that is the type of conditions that I also deal with and I enjoy growing native plants and collecting and growing seeds of those types of natives.
For reference: here’s a pretty good guide by Rutgers University on many landscape and native plants rated by deer resistance: https://njaes.rutgers.edu/deer-resistant-plants/
The first I’ll mention are the Serviceberries/Juneberries (Amelanchier). The big draw with these is that they are excellent native small tree/shrub species that benefits many types of wildlife, while also giving edible and tasty fruits that we can eat. They are usually listed as at least somewhat deer-resistant, so I’m guessing they are a low preference for browse. They are also a very nice looking landscape tree with showy blooms in spring and nice fall colors. Species that are native to the northeastern U.S. include A. arborea, canadensis, laevis, humilis, spicata, and sanguinea. There are also some cultivars available at many nurseries that are crosses between A. arborea and A. laevis (referred to as Amelanchier x grandiflora), including Autumn Brilliance, Princess Diana, and Robin Hill.
Chokeberries (Aronia) are nice wildlife shrubs that have berries that may not be very palatable to most people on their own, but can be very good processed and made into jams, juices, or desserts. The native species of Chokeberry are the Black Chokeberry (Aronia melanocarpa) and Red Chokeberry (Aronia arbutifolia). I know that there are cultivars available of the Black Chokeberries, not sure about the Reds.
The American Hazelnut (Corylus americana) could also be a good choice as it does well in dry soil, is a low deer preference, and give edible nuts for humans and wildlife.
Sumacs could also be included as shrubs/small trees with good deer resistance that have edible fruits since they have berry clusters that can be used to make sumac lemonade (I make this every summer and it is delicious!). Sumacs are well known for being extremely good at thriving in poor and dry soil and are often used for erosion control. They are a valuable food source for winter and migrating birds since the berry clusters persist through winter, have flowers that are very attractive to bees, and have beautiful red fall leaves. Our native species include: Staghorn Sumac (Rhus typhina), Smooth Sumac (Rhus glabra), Winged/Shining Sumac (Rhus copallinum), and Fragrant Sumac (Rhus aromatica). Cultivars are available of some of these species. I know that there’s a dwarf, yellow leafed variety of Staghorn Sumac called Tiger Eyes and a very short variety of Fragrant Sumac called Gro-Low. Note: Poison Sumac (Toxicodendron vernix) is the only Sumac we have that is poisonous, but it is not commonly encountered as it likes very wet conditions and tends to grow only in swamps and bogs.
Blueberries may or may not have some deer resistance, depending on location (they don’t touch mine), but there are 2 native species that are actually pretty tolerant of dry soil conditions: the Lowbush Blueberry (Vaccinium angustifolium) and the Dryland/Blue Ridge Blueberry (Vaccinium pallidum).
If we look at native plants that give fruit that aren’t edible to humans, then there are many more options.
Northern Bayberry (Myrica pensylvanica) is a very deer resistant shrub that grows very well in dry and poor soil conditions as it is a nitrogen-fixing species. It occurs naturally along sandy seashores as well as wetlands, so it is well adapted to a wide range of conditions. It has white, waxy berries that persist on the shrubs through winter and are a valuable resource for birds. The berries are also pleasantly aromatic and can be made into candles, soaps and sealing wax.
Other native shrubs/small trees that are deer-resistant, do well in dry soil, give fruit or seeds for wildlife, and that I think are worth looking into are: False Indigo Bush (Amorpha fruticosa), Devil’s Walking Stick (Aralia spinosa), Summersweet (Clethra alnifolia), Sweetfern (Comptonia peregrina) (a shrub that looks like a fern), Ninebark (Physocarpus opulifolius), & Mapleleaf Viburnum (Viburnum acerifolium).
