Although Arches may appear harsh and unchanging, the desert ecosystem is continually evolving. Weather, climatic shifts and geologic processes continue to shape this environment as they have for millennia.

More recently, human-caused factors such as air, noise and water pollution, as well as introduced species, have had a much greater impact on natural resources world-wide.

The undeveloped landscape of Arches provides an ideal place to study how various environmental factors affect desert ecosystems, and predict what changes might be expected in the future.

Common Raven

The common raven displays abilities to play and problem-solve that are rare among animals. This member of the crow family is also very vocal, communicating with over a dozen sounds. Perhaps because of these qualities, ravens have achieved a certain stature in both European and Native American folklore.
