the trees were last topped in 2000 for flight safety, repeated topping makes
them hazardous to work around. Permanently removing the cottonwoods and

replace them with more than 23,000 lower-growing, native shrub and small tree
species such as vine maple, Oregon grape, red-flowering currant and native
roses and willow.
