Pipe Spring 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.

“Paa” ute means water ute, and explains the Southern Paiute preference for living near water sources. The Spanish explorer Escalante kept detailed journals of his travels in the Southwest and made notes concerning Southern Paiute horticulture, writing in 1776, that there were “well dug irrigation ditches” being used to water small fields of corn, pumpkins, squash, and sunflowers.

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.

Dinosaur fossils have been discovered at or are associated with at least 27 NPS units. Geographically, their finds are concentrated in the parks of the Colorado Plateau, but they have been found from central Alaska to Big Bend National Park in Texas to Springfield Armory National Historic Site in Massachusetts. The most famous site is the Dinosaur Quarry of Dinosaur National Monument, but a rush of new finds since the 1970s has greatly expanded our knowledge.

Because birds can be sensitive to habitat change, they are good indicators of ecosystem integrity. The Northern Colorado Plateau Network partners with the University of Delaware to assess breeding-bird species trends in three different habitats: low-elevation riparian, pinyon-juniper, and sage shrubland. Find out which species were increasing and declining at network parks as of 2018.
