You might never have given a second thought to the culture of trees growing on the University of Colorado campus in Boulder, but veteran groundsman Alan Nelson, who's been caring for them for years, thinks they're more than just trees. That's why every spring and fall, he takes a break from his duties to introduce the public to the 5,000 trees and 100 species from all over the world that keep the CU campus shady in the summertime and colorful in the fall. That would include an original centenarian cottonwood in a grove near Old Main, as well as silver maple, tulip tree, sumac, redbud and Nelson's favorite red oak, among others. Think of it as more than another walk in the woods; Nelson will no doubt sprinkle the tour with lore and practical knowledge.
Meet for the Spring Tree Walk this evening at 5 p.m. at the south door of the sponsoring University of Colorado Museum of Natural History, near 15th Street and Broadway in Boulder; the walk, which lasts about an hour, is free and open to the public. For information, go to cumuseum.colorado.edu or call 303-492-6892.
