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.

Making an Impact: Long-Term Monitoring of Natural Resources at Intermountain Region National Parks, 2021 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. A man looks through binoculars at sunrise. A Changing Bimodal Climate Zone Means Changing Vegetation in Western National Parks 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.

In warmer months, hike during morning or evening to avoid heat exhaustion and burned feet. Wear closed-toe shoes. Be cautious when hiking with pets. Hot sand can burn dogs’ paws. Take necessary precautions by reducing the amount of time you are hiking on hot sand, or cover paws with dog shoes. Lightning Lightning can occur anytime during the warmer months (especially July – August), when afternoon storms approach the dunes. Avoid fatal lightning strikes by experiencing the dunes and other open areas during morning hours. Remain in a building or vehicle until 30 minutes after the last thunder. If you are in immediate danger, crouch in a low-lying area on top of a backpack or other item to prevent a ground charge. Areas with trees are slightly more safe than open areas. Driving Rangers enforce speed limits to keep the roads safe for visitors and wildlife. Please abide by speed limits to arrive alive. Wildlife Never feed or approach wildlife. Keep a safe distance when viewing wildlife. Food and scented items should be stored out of sight in your vehicle or in bear proof containers in the campground or along Medano Pass Primitive Road campsites. Bear hangs or bear proof containers are Ranger Vehicle required in the national park and preserve backcountry. High Winds Winds are possible any time of the year and can cause sand to move. Wear eye protection, long sleeves, and pants to avoid getting sand-blasted when hiking during high wind conditions. Check the weather forecast on the park website or at the visitor center. High Elevation Elevations within the park and preserve range from 8,000 feet to 13,604 feet (2,438 m to 4,146 m). Stay hydrated, wear sun protection, and hike slowly. In the higher-elevation backcountry, pack layers to avoid hypothermia. If you experience shortness of breath, headaches or nausea: rest, hydrate and slowly descend from your elevation.

The only paved-highway access is via US 160 and CO 150 from the south, or CO 17 and County Lane 6 from the west. • Lightning strikes can be fatal: If you see a thunderstorm, get off the dunes! Storms and cold weather can occur any time of the year. • Summer sand surfaces reach 140ºF. Hike dunes in early mornings or evenings then. Wear closed-toe shoes and moni- tor pets’ feet. • Elevations range from 7,500 to nearly 14,000 feet: Seek medical advice about doing vigorous exercise. Elevation sickness symptoms are short breath, headache, and nausea. Drink lots of water. Great Sand Dunes is one of over 390 parks in the National Park System. To learn more about national parks and National Park Serv­ice programs in America’s communities, please visit www.nps.gov. Get a copy of “Wild Ways” at the visitor center to learn about bears and mountain lions. Store food, toiletries, and trash in bear-proof boxes in campgrounds. Do not feed any wildlife. It is dangerous for you and unhealthy for them. Great Sand Dunes Wilderness In 1976 Congress designated the Great Sand Dunes Wilderness for protection under the 1964 Wilderness Act. The 33,549-acre wilderness of dunes and mountains abuts the 220,803-acre Sangre de Cristo Wilderness. Wilderness designation protects forever the land’s wilderness character, natural conditions, opportunities for solitude, and scientific, educational, and historical values. In wilderness, people can sense being a part of the whole community of life on Earth. Preserving wilderness shows restraint and humility, and it benefits generations to come.

Origins of the Dunes This map of the park and preserve shows how wind and water move sand, continually forming dunes. Most sand comes from the San Juan Mountains, over 65 miles to the west. Larger, rougher grains and pebbles come from the Sangre de Cristo Mountains (right). Sand and sediments from both ranges washed into a huge lake once covering the valley floor. As the lake shrank, prevailing southwesterly winds (large white arrow) bounced sand grains to pile up beneath the Sangre de Cristos or to be washed back toward the valley floor (small blue arrows). Northeasterly storm winds (small white arrows) blast through mountain passes, piling dunes back on themselves and creating North America’s tallest dunes. Research suggests that the dunes are less than 440,000 years old, but we don’t yet know their exact age.
