Yucca House National Monument

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 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.

The combination of high. elevation and a semi-arid climate makes the Colorado Plateau particularly vulnerable to climate change. Climate models predict that over the next 100 years, the Southwest will become warmer and even more arid, with more extreme droughts than the region has experienced in the recent past.

In conjunction with a forthcoming boundary expansion of Yucca House National Monument, in southwestern Colorado, a park-specific paleontological resource inventory was coordinated by paleontologist Victoria Crystal.

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.

Springs are important water sources in arid landscapes, supporting unique plant associations and sustaining high levels of biotic diversity. Because springs rely on groundwater, they can serve as important indicators of change in local and regional aquifers. On the Colorado Plateau, spring ecosystems also provide vital habitat for both endemic and regionally rare species, including several types of orchids and declining populations of leopard frogs.

Each park-specific page in the NPS Geodiversity Atlas provides basic information on the significant geologic features and processes occurring in the park. Links to products from Baseline Geologic and Soil Resources Inventories provide access to maps and reports.
