The Fort Collins Forestry Department maintains the more than 40,000 trees on city property. This job includes, among other things, pruning, planting, removal, insect and disease identification and control, and a Memorial Tree program. They also put together maps for self-guided tours of the 233 tree varieties in City Park and the Notable Trees around town. The latter is compiled in conjunction with the Colorado Tree Coalition, which maintains a list of our state's champion trees.
I also learned that Fort Collins is home to the state's largest Red, White, and (Thomsen) Blue Spruces, which makes me feel downright patriotic.
