Let's see, when we moved in 3 years ago, we only had:
-red pine
-dwarf white spruce
-lilac
-silver maple (these will be removed in the next 5-8 years)
-white poplar (these will also be removed in the next 5-8 years)
-one apple
-chokecherry
Since then, I've added:
-pawpaw
-persimmon
-more apples
-medlar
-yellowhorn
-dwarf cherry
-hybrid Japanese plum
-seven-son's flower
-black chokeberry
-hybrid chestnut
-apricot
-hazel
-walnut
-juneberry
-honeyberry
-rugosa rose
-sea buckthorn
-Cornelian cherry (actually a species of dogwood)
-red-twig dogwood
-arborvitae
-anise magnolia
AND, I just sent in another mail order for 40 more plants of 20 more species of fruiting trees and shrubs this weekend. I also have hundreds of seeds stratifying in potting soil in my unheated garage for spring planting, including 200 hybrid chestnut seeds and 50 Russian walnuts. My ultimate goal is to have as many edible trees and shrubs as possible on my land, both for human and animal consumption, and give away the excess I grow from seed and cuttings to neighbors, friends, family, coworkers, etc. Most of the plants I have are still relatively small (nothing I've planted is over 6 ft yet), since I saved money by purchasing smaller saplings via mail order/Internet or growing from seed, but I'm a patient man.
