Reds Meadow Road and shuttle service, which provide access to Devils Postpile, will only be open Fridays–Sundays (and on Thursdays with one-hour delays in July and August). The road will tentatively open for the season on July 3 and close October 6, 2025. More
Climate scientist installs climate monitoring equipment. In 2006, National Park Service staff worked with the California Department of Water Resources and the Scripps Institution of Oceanography at the University of California to establish this meteorological monitoring station at the monument.
For a relatively small monument, Devils Postpile is the site of a wide range of research and monitoring projects. Although we often talk about research and monitoring together, they are different. The monument is engaged in both. For example, the work being done on air quality and cold air pooling is considered research. There are definitive questions for which monument staff is trying to find answers.
Natural resource inventories help managers understand the current state of resources in the monument (abundance and distribution of species, water quality, forest health). Long-term monitoring tracks changes in the condition of natural resources. Some of this work is part of larger studies or monitoring efforts that encompass parks and forests throughout this part of the Sierra Nevada, and it informs understanding and knowledge of what makes this landscape such a diverse one.
Research, inventories, and monitoring are often conducted in partnership with other agencies, parks, or partners. Please contact us if you are interested in information on a particular study or project. For more information on projects conducted by the Sierra Nevada Network at the monument, visit our Inventory & Monitoring page.

Might cold air pooling offer relief from summer warming?
Cold air pooling (CAP) occurs in low-lying areas where cold, dense air collects during nighttime hours, producing colder temperatures than surrounding higher elevations. Devils Postpile National Monument is confined by steep mountain ridges, which promote cold air drainage into lower-elevation meadows and river valleys. These low-lying areas where CAP occurs could help facilitate a potential refugium from some of the greatest impacts of regional climate warming. A refugium in this context is an area of the landscape that may be sheltered from the intensity and rapid pace of climate change, possibly allowing more time for species to adapt to new conditions.
Read the paper to learn more about cold air pooling and the importance of monitoring and ongoing analysis to guide conservation and adaptation approaches.

From coast to coast, the NPS Inventory and Monitoring Division is helping park managers improve the health and function of forest ecosystems. From promoting resilient forests in the Northeast, to conserving whitebark pine in the West, to protecting Hawaiian forest birds from avian malaria, scientific partnerships are helping parks to share information, leverage funding sources, and work together for outcomes that extend beyond what any park could accomplish on its own.

Found mainly on public lands, whitebark pine is one of America’s most threatened and ecologically valuable tree species. A multi-agency alliance is using innovative strategies based on science to help it avoid extinction. Recent federal funding is helping.

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.

To steward amphibians effectively, managers need basic information about which species live in parks. But species lists need constant maintenance to remain accurate. Due to recent efforts, the National Park Service now has an up-to-date amphibian species checklist for almost 300 parks. This information can serve as the basis for innumerable conservation efforts across the nation.
Information on changes in temperature, precipitation, windspeed, and other
variables, or weather, is important for visitors planning trips to Devils Postpile National Monument (DEPO), and for helping monument managers understand short-term variation in natural processes and resources. This article highlights the importance of monitoring weather at DEPO, discusses installation and interpretation of a local monitoring station, and links to other local sources of climate data.
An unusual wind event affected significant portions of the southern Sierra Nevada
November 30 to December 1, 2011. An anemometer at Mammoth Mountain, California recorded winds that exceeded 145 km/hour, with a predominantly NNE direction.
Extensive windthrow of trees occurred in Devils Postpile National Monument and other areas of the Sierra Nevada. This article summarizes a study describing the forest stand in the monument at time zero after this extreme event.

Birds occur across a wide range of habitats and their sensitivity to change makes them good indicators of ecosystem health. The Sierra Nevada Network partners with The Institute for Bird Populations to monitor breeding-bird species. Population trends between 2011 and 2019 are summarized by species and park, and in relation to mean spring temperature and amount of snow. Learn which species were increasing or declining at network parks during this period.

The Sierra Nevada national parks contain the headwaters of seven major watersheds, and the gradual spring melt of the winter snowpack provides water to park ecosystems as well as rural and urban areas throughout California.

Wetlands occupy less than 10 percent of the Sierra Nevada, but they are habitat for a large diversity of plants and animals. They provide nesting and foraging habitat for birds, play an important role in the life cycle of many invertebrate and amphibian species, and are a rich source of food for small mammals and bears. They store nutrients and sediment and control flooding. Learn more about monitoring of plant communities, groundwater dynamics, and macroinvertebrates.

More than 60 percent of the vertebrate species in Sierra Nevada Network parks are birds. These parks provide critical breeding, stopover, and wintering habitats for birds, but there are numerous stressors such as climate change and habitat loss that cause declines in some bird populations.
