Climate Smart Conservation Planning for the National Parks In response to climate change, park managers are having to rethink how they plan for the future. Climate Smart Conservation is a process that can help managers achieve goals in the face of coming changes. Under this framework, scientists and managers use their collective knowledge to anticipate problems and be proactive, rather than reactive. Pika with a mouthful of grass Monitoring From Space: Using Satellite Imagery to Measure Landscape Conditions on the Ground Scientists from the Northern Colorado Plateau Network travel thousands of miles each year to collect data on plants, soils, and water across network parks. But it would be impossible to cover every square inch of the Northern Colorado Plateau with boots on the ground. Instead, we simultaneously monitor the parks with boots in space—satellite data that provide information at a much broader scale. Satellite and Earth in space Responding to Climate Change in the Southeast Utah Parks This paper describes how the Southeast Utah Group of parks is responding to climate change. The paper summarizes expected future climate conditions compared with a 20th Century baseline. It describes the foundation of our work within the Climate Smart Conservation framework adopted at our initial workshop in December 2018. A photograph of a grassland, containing some shrubs. Localized Drought Impacts on Northern Colorado Plateau Landbirds Birds of the desert southwest, a climate-change hotspot, are among the most vulnerable groups in the US. To help park managers plan for those changes, scientists evaluated the influence of water deficit on landbird communities at 11 national parks in Utah and Colorado. The results will help land managers to focus conservation efforts on places where certain species are most vulnerable to projected climate changes.

Visitor Guide National Park Service U.S. Department of the Interior Arches We Need Your Help The La Sal Mountains with the Windows Section in the foreground NPS / PAUL STOLEN BY RACHEL JOHA Arches National Park is a destination for over 1.5 million people a year. Numbers like that can have a huge impact on the landscape. No matter your experience in the outdoors, we all play a role in protecting and preserving our public lands. The Seven Principles of Leave No Trace are helpful guidelines to minimize your impact here at Arches or anywhere you visit. Plan Ahead and Prepare Plan your trip activities to match your goals, skills, and abilities. Research the park and current conditions ahead of time. Bring enough water, a map, food, and appropriate gear so you don’t need rescuing. Dozens of hikers at Delicate Arch and Devils Garden get in trouble every year from lack of preparation. Dispose of Waste Properly “Pack it in, pack it out.” Don’t leave behind any trash or food scraps. In arid climates like ours, organic litter like orange peels or nut shells does not decompose quickly. “Go before you go.” Before starting a hike, use the bathroom and carry a human waste disposal bag for emergencies. Travel and Camp on Durable Surfaces Concentrating your activity on nonvegetated durable surfaces (e.g. a trail, rock, a drainage path, or pavement) spares vegetation, sand dunes, and soil crust from damage. Don’t walk through desert puddles, whether they are wet or dry. They contain living organisms. Leave What You Find Chalking, carving, scratching, or painting on the rocks is considered graffiti and is illegal. Cairns (stacks of rocks) mark routes in the park. Don’t change existing ones or build your own, which can mislead other hikers. Welcome to Arches Drink water. It is easy to become dehydrated here, even in cold temperatures. Plan on drinking at least 1 gallon (4 L) of water per day. You can get water at Arches Visitor Center and Devils Garden. Minimize Campfire Impacts Never leave a fire unattended, and thoroughly extinguish all fires. Fires are only allowed in designated pits at Devils Garden Campground and in picnic areas. Collecting firewood or kindling is not allowed in the park. Respect Wildlife Do not feed wild animals. Secure your food and trash so clever ravens can’t get into it. Keep pets under control and on a leash so they don’t harm or stress wildlife. Pets are not allowed at overlooks, on trails, or in the backcountry, even in carriers. Observe wildlife quietly from a safe distance so as not disturb them. Be Considerate of Other Visitors Avoid disrupting natural quiet with loud music or shouting. Remember— you share public lands with other visitors. Respect and protect the quality of everyone’s outdoor experience. Thank You! Practicing these Leave No Trace outdoor principles is a powerful way to show your love and help preserve public lands for future generations. Have a safe and enjoyable visit by remembering these rules and advisories. Keep off the arches. It’s prohibited—and dangerous—to climb on any arch or on prominent features like Balanced Rock. The sun is intense, and shade is rare. Avoid exertion during peak heat (>90°F /32°C). Protect yourself with sunscreen, sunglasses, and a hat. Do not rely on cell service at Arches. Coverage varies throughout the park. There are pay phones at the visitor center. Emergency? Call 911 Walk on hard surfaces. Stay on trails to protect fragile biological soil crusts and plant and animal habitat, and to reduce your risk of getting lost. Watch your step. Rocks fall. People fall. Sandstone is slippery when wet or icy. In winter, avoid snowy or icy trails. Respect nature. Leave plants, rocks, and artifacts where you see them. Do not feed or disturb animals. Leave drones at home. Launching, landing, or operating unmanned aircraft (such as model airplanes, quadcopters, or drones) is prohibited. Leave the rocks as you see them. Graffiti—carving, scratching, chalking, or any type of marking—is illegal and unsightly. Find your way. Cairns (small rock piles) mark routes. Don’t build your own; they could mislead other hikers. If you get lost, stay where you are, and wait for rescue. Preserve natural darkness. Using artificial light sources to illuminate features for photography at night is prohibited. Do not use ATVs. It’s prohibited to use any type of ATV or OHV. There are many roads outside the park where you can use ATVs and OHVs. Emergencies call 911 National Park Service U.S. Department of the Interior Park Information i HOURS OF OPERATION ` PETS The park is open 365 days a year.

The Transforming Power of Water The Devils Garden Trail leads you between sheer sandstone walls, called fins, to discover arches and views not visible from the trailhead. The long geologic story behind this landscape testifies to the absolute power of water. River. The water is so loaded with sediment that it becomes the same color as the rocks. Where parallel cracks widen enough, tall fins of rock may remain standing between them, such as those at Devils Garden. When we peer through arch openings or observe a distant thunderstorm, we are reminded of the dynamic nature of our Earth. Some of the sand beneath your feet could have been a majestic arch long ago. In time, today’s familiar arches, buttes, and spires will return to shifting sand and perhaps one day become the ingredients for another awe-inspiring landscape. Stone arches may only last a few thousand years, but the events that led to their creation here began about 300 million years ago, when seas periodically covered this area. The seas became trapped in low-lying areas and then evaporated, leaving salt beds that were up to 5,000 feet (1,524 m) thick in some places. Over the following millions of years, as nearby mountains eroded, layers of sand, silt, and clay accumulated on top of the salt deposits and became rock. The uneven weight and pressure of these overlying rock layers squeezed the salt into a domed ridge, what geologists call an anticline. Where rock bulged upward, vertical cracks formed that allowed rainwater to trickle down and, eventually, dissolve the salt away. As the salt receded, the overlying dome of rock collapsed. Arches’ Salt Valley is an example of the resulting landform. In some places, weak zones in fins may be dissolved by naturally occurring acids in rainwater or wedged apart by freezing and thawing water, and openings develop. These openings may evolve into the varied and splendid arches that capture our attention. Landscape Arch, one of the world’s longest stone spans, stretches 306 feet (93 m), yet is Devils Garden T R A I L G U I D E Landscape Arch in the 1950s. Oval indicates area from which rock fell in 1991. Compare this photograph with the slope under the arch today. Notice the numerous foot paths under the arch in the photo, caused by people walking off the trail. These “social trails” kill vegetation and invite erosion of the desert landscape. Since the trail under the arch has been closed, the vegetation is slowly recovering. National Park Service U.S. Department of the Interior only about 11 feet (3.3 m) thick at its center. Arches can erode at any time, such as in September 1991 when a 60-foot-long (18 m) slab of rock dropped from the underside of the arch’s thinnest section. Some of the large boulders on the slope beneath Landscape Arch are remnants of this event, and reminders why it is best not to linger too long beneath an ARCH FORMATION arch. The power of water to transform a landscape is still evident at Arches today. Rain and snow soak into vertical cracks, dissolving cementing minerals within the rock and loosening grains of sand. Running water carries this material away, most dramatically during summer thunderstorms, when normally dry streambeds surge toward the Colorado Arches National Park 2282 Resource Blvd. Moab, UT 84532 www.nps.gov/arches 435-719-2299 phone 435-719-2305 fax Published by Canyonlands Natural History Association Map by Jim Stiles Quote from The Dynamic Earth: An Introduction to Physical Geology, by Brian J.

From Landscape Arch to Double O Arch, the trail becomes more difficult. Expect steep, sloping surfaces and close proximity to drop-offs. Sandstone is often called slickrock and can be slippery even when dry. The primitive trail is most difficult. Expect difficult route finding, steep slopes, narrow drop-offs, and rock scrambling. Hiking the primitive loop requires crossing a pool that may contain water. We don’t recommend hiking the primitive trail when snow or ice cover the routes. Distances: To Landscape Arch and back: ...1.6 miles (2.6 km) To Double O Arch and back: ......4.2 miles (6.7 km) To Dark Angel and back: ....... 5 miles (8 km) To Dark Angel and return via Primitive Loop: .......5.9 miles (9.5 km) Trail to Pine Tree and Tunnel arches: .............. add 0.5 miles (0.8 km) Trails to Navajo and Partition arches: ............. add 0.8 miles (1.3 km) Total distance, all trails: ..........................................7.2 miles (11.5 km) Stay on the trail to protect fragile desert soils and biological soil crusts. Carry and drink plenty of water: at least 1 quart (1 L) for every two miles that you hike. The Transforming Power of People “Each and every one of us plays a part in the changes th
