COLORADO SPRINGS AND CAMPUS ECOLOGY 

Introduction to Campus Ecology

When Europeans settled this region, short-grass prairie covered the area where dorms and academic buildings now stand. With hopes of creating a greener and more lush campus, people have manufactured the landscape and ecology of Colorado College since its founding in 1874. Currently less than 10 percent of the landscape on campus is occupied by native plant species. The nonnative Kentucky bluegrass looks nice and tolerates heavy use very well, but requires at least twice as much water as normally falls in this area (Colorado College does use recycled water to irrigate the majority of its quads). The beautiful deciduous trees on campus are also not native to this area but were imported mostly from the much wetter regions of eastern North America and survive due to the same irrigation that allows the Kentucky bluegrass to thrive. Over 80 percent of the landscape on campus consists of non-native grasses (Kentucky bluegrass, rye grass) or non-native trees. Areas dedicated to native turf exist around the Grounds Shop, the Synergy Houses, North Palmer Quad Parking area, the Southwest Studies Department and Cutler Hall.

 Fox squirrels, brown with an occasional black individual, thrive in this environment; students even occasionally see a hawk predate a squirrel. The most prominent birds include rock doves (a European import), American robins, and the American crow. At the pond on the other side of Monument Creek, you will likely see Canada geese and mallards, and if you walk north along the creek from Uintah Street, you might see red foxes, especially at dusk.

Trees on campus

There are approximately 1,665 trees on campus. The percentage of existing trees native to the Colorado College campus climate zone is very small, as the campus was originally just a short grass prairie with a riparian belt along Monument Creek on the west side of the college. Although many of the trees on campus would not grow naturally in the historic short grass prairie, the richness of species diversity has educational and aesthetic value and supports its own urban ecosystem.
