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; land disturbance; and introduced nonnative species have had a much greater impact on natural resources world-wide. Arches' naturally dark night skies are also impacted by electric lights in nearby communities.
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.

In a world where excess light is wiping out our views of the stars at a startling pace, parks can protect natural darkness. But do nighttime visitors support the changes parks must make to bring back dark night skies? We didn’t know until we asked them.

Good, clean water is essential for healthy ecosystems--for people, vegetation, and animals--making it one of the most important resources in the semi-arid west. The Northern Colorado Plateau Network and its partners monitor water quality in 8 national parks in Utah and Colorado to help scientists and managers conserve these resources. This article summarizes 2019-2022 water quality data and how they compare to state standards.

Across the US, changes in water availability are altering which plants grow where. These changes are evident at a broad scale. But not all areas experience the same climate in the same way, even within the boundaries of a single national park. A new dataset gives park managers a valuable tool for understanding why vegetation has changed and how it might change in the future under different climate-change scenarios.

Birds of the desert southwest, a climate-change hotspot, are among the most vulnerable groups in the US. To help park managers plan for those changes, scientists evaluated the influence of water deficit on landbird communities at 11 national parks in Utah and Colorado. The results will help land managers to focus conservation efforts on places where certain species are most vulnerable to projected climate changes.

Scientists from the Northern Colorado Plateau Network travel thousands of miles each year to collect data on plants, soils, and water across network parks. But it would be impossible to cover every square inch of the Northern Colorado Plateau with boots on the ground. Instead, we simultaneously monitor the parks with boots in space—satellite data that provide information at a much broader scale.

When the climate changes enough, the vegetation communities growing in any given place will also change. Under an expanded bimodal climate zone, some plant communities in western national parks are more likely to change than others. National Park Service ecologists and partners investigated the future conditions that may force some of this change. Having this information can help park managers decide whether to resist, direct, or accept the change.

Across the Intermountain Region, Inventory & Monitoring Division ecologists are helping to track the effects of climate change, provide baseline information for resource management, evaluate new technologies, and inspire the next generation of park stewards. This article highlights accomplishments achieved during fiscal year 2021.
