I count 5 factors: 1)Leaves a) Ideal Trees (Ginkgo and Oriental Spruce) Ginkgo Tree/Clean Tree Oriental Spruce/Clean Tree Leaves b) Winter Leaf Retention (Pin Oak and Shingle Oak) c) Leaves that decompose slowly (Evergreen Magnolias, Oaks, and Sycamores) vs Quick decomposers (Maples, Elms, and Tulip trees) Brackens Evergreen Magnolia Sycamore Sugar Maple Tulip Tree Princeton American Elm Leaves d) Leaf drop due to disease or environmental stress, disease resistant Crabapples, River Birch vs Prairie Gold Aspen Crabapple Tree River Birch Prairie Gold Aspen 2)Weak, brittle wood Many times, it’s the faster growing trees that produce the weakest wood. Silver maples, willows, Siberian elms, and Callery pears such as the Bradford are examples. These trees are all susceptible to breaking up from ice storms, thunderstorms, or high winds. Weak, brittle wood Consider planting slower growers with stronger wood such as Sugar maples, disease resistant cultivars of American elm such as Princeton, or parrotia also called Persian ironwood. Some of the slower growing native oaks have some of the strongest wood, e.g., burr oak which has stronger wood than the much faster growing pin oak. Parrotia Tree Burr Oak 3) Fruit Examples include acorns, pine cones, drupes (dogwood trees and hollies), aggregate of follicles (magnolia), samara (maple trees), a syncarp of drupes (hedge apple tree), berry-like pome (serviceberry), pome (crabapple), pod (locust trees, redbuds), gumballs (sweetgum tree) Nellie Stevens Holly Honey Locust Tree Fruit Birds and other animals often eat the fruit of some trees before it ever drops.
