Bradford Pear forms dense thickets that suppress other plants including native species that can’t tolerate the deep shade or compete with pear for water, soil and space. A single tree can spread rapidly by seed and vegetative means forming a sizeable patch within several years. Its success as an invader results from its capacity to produce copious amounts of seed that are dispersed by birds and possibly small mammals, seedlings that germinate and grow rapidly in disturbed areas, and a general lack of natural controls like insects and diseases, with the exception of fire blight.
Ohio and soon South Carolina are officially banning the sale of Callery or Bradford Pear and all of their cultivars.
