Smoke is monitored as PM2.5 (particulate matter that is 2.5 micrometers and smaller) using devices such as Purple Air (PA) monitors. Sequoia and Kings Canyon National Parks (SEKI) experienced significant smoke impacts in 20 due to high severity wildfires.

NPS Photo Creating Portable Air Monitors for Protection Soon to disappear, these glaciers are among Yosemite's most visible indicators of climate change. Monitoring glacier movement provides an important link to understanding how a glacier changes over time in mass and makeup. They found that Maclure Glacier has slowed, creeping at about half an inch per day, and that the Lyell Glacier did not move. In 2022, park scientists reproduced Muir’s experiment 150 years ago to the day on Maclure and Lyell Glaciers, which have lost 90% of their 1872 volumes. Both the Lyell and Maclure glaciers have been steadily retreating since they were first mapped and photographed in 1883, but melting has accelerated rapidly in the past decade. On August 21, 1872, naturalist John Muir installed stakes in the Maclure Glacier and returned 47 days later to find that the stakes moved an inch per day. Yosemite’s Lyell and Maclure glaciers are among the longest studied glaciers in North America.

The people doing this work across the Pacific West Region are a diverse cohort: from a Mexican Ph.D. In the National Park of the American Samoa, park managers are learning from the Samoan community, researching their traditional ecological practices to be better co-stewards of the land. Conserving our nation’s rich cultural heritage – the stories, places, traditions, and artifacts that make up the fabric of our shared history – is an important part of the National Park Service (NPS) mission.
Our parks are places where the distance between today and the past thins, and we can examine the triumphs and shortfalls of our ancestors while standing in their footsteps. Their landscapes are laboratories where we can study plants and animals that exist nowhere else, from the Mission Blue Butterflies in the San Francisco Bay Area to the Devils Hole pupfish eking out a living in the driest, hottest place in the country.
Parks are places of great research potential, where scientific inquiry helps us better understand the natural world around us and the historic events that got us here.
