In the early 1900s, paleontologists unearthed the Age of Mammals when they found full skeletons of extinct Miocene mammals in the hills of Nebraska -- species previously only known through fragments. At the same time, an age of friendship began between rancher James Cook and Chief Red Cloud of the Lakota. These two unprecedented events are preserved and protected here... at Agate Fossil Beds.

Prescribed Fire used to Remove Invasive Species and Reduce Hazardous Fuels
Agate Fossil Beds National Monument conducted a prescribed fire in the mixed grass prairie and wetlands of the Niobrara River basin. The goals of the approximately 670-acre burn were to decrease fuel loading and the presence of invasive plant species in and around the floodplain. Fire serves as a natural, and necessary, control on the buildup of plant matter and invasive plants.

Plant Community Monitoring at Agate Fossil Beds National Monument
The lush valley and remote rocky outcrops at Agate Fossil Beds National Monument are home to over 363 plant species. Native plant diversity is moderate in the mixed-grass prairie at the park compared to other grasslands in the region. Monitoring can track changes to plant communities over time, as well as document species of management concern.

Landbird Monitoring at Agate Fossil Beds National Monument
A mix of large swaths of ungrazed, mixed grass prairie, and the broad floodplains of the Niobrara river, has created wonderful habitat for wetland birds. Land bird surveys have been conducted at Agate Fossil Beds NM since 2012

Bat Acoustic Monitoring at Agate Fossil Beds National Monument
Agate Fossil Beds National Monument is a 3,058-acre park that is primarily mixed-grass prairie, but there are small groves of old cottonwoods in the floodplain of the Niobrara River that provide good roosting and foraging habitat for bats. We monitor bats using acoustic recorders to understand their current status and to detect long-term changes in bat populations.

Wind Cave National Park, Nebraska National Forest Join to Teach Firefighters Ignition Operations Course
In May 2014, students of wildland fire and fire management from the National Park Service, US Forest Service, Nebraska Forest Service, South Dakota Division of Wildland Fire, Bureau of Indian Affairs, Pheasants Forever, and private contractors learned key principles of firing operations in the wildland and prescribed fire environments at a cooperative presentation of the S-234, Ignition Operations course, at the Nebraska Wildland Fire Academy in Ft. Robinson, Nebraska.

Management and restoration of high quality, mixed-grass prairie to the NPS units has proved difficult and complex. The Annual Brome Adaptive Management project (ABAM) is attacking this problem through a cooperative effort.

Series: Geologic Time Periods in the Cenozoic Era
The Cenozoic Era (66 million years ago [MYA] through today) is the "Age of Mammals." North America’s characteristic landscapes began to develop during the Cenozoic. Birds and mammals rose in prominence after the extinction of giant reptiles. Common Cenozoic fossils include cat-like carnivores and early horses, as well as ice age woolly mammoths.

Series: Prairie Ecology of the Badlands
Badlands National Park is home to the nation's largest expanse of mixed-grass prairie. Here, plant species from both short-grass and tall-grass prairies mingle to create a unique home, well suited to many animals which call the park home.

Series: Badlands Geology and Paleontology
Badlands National Park is well-known for its geology and paleontology. Fossils found in the park range from 75- to 28-million years old and many are in excellent condition. The flat-lying layers of the park's formation represent classic sedimentary rock layers.

Series: Plant Community Monitoring in Northern Great Plains Network Parks
Plant communities are essential components of all major ecosystems. Plants are the ultimate source of food for other organisms and the main source of organic material in soil and water. They also influence climate and provide the scenery that park visitors enjoy. The NPS Northern Great Plains Network monitors the number, identity, and relative abundance of plant species, as well as their horizontal cover and vertical structure, to determine the health of park ecosystems.

Women & Paleontology in the Badlands
Although Badlands National Park is proud to employ many female paleontologists today, this scientific field was not always accepting of women. In this article, learn about how women's roles in paleontology have changed over years of Badlands research.

Paleogene Period—66.0 to 23.0 MYA
Colorful Paleogene rocks are exposed in the hoodoos of Bryce Canyon National Park and the badlands of Badlands and Theodore Roosevelt national parks. Extraordinary Paleogene fossils are found in Fossil Butte and John Day Fossil Beds national monuments, among other parks.

Top 10 Tips For Visiting Agate Fossil Beds
Make your visit to Agate Fossil Beds enjoyable, educational and safe with these top 10 tips from our rangers!
Changing Patterns of Water Availability May Change Vegetation Composition in US National Parks
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.

Volcanic Ash, Tephra Fall, and Fallout Deposits
Volcanic ash, pumice, and tephra ejected in volcanic eruptions ultimately falls back to Earth where it covers the ground. These deposits may be the thin dustings or may be many tens of feet (meters) thick near an eruptive vent. Volcanic ash and tephra can present geohazards that are present great distances from the erupting volcano.

Bats: A Junior Ranger's Perspective
Every few years, researchers from the University of Wyoming's Biodiversity Institute monitor and study the bat population at Agate Fossil Beds National Monument. In 2021, a few lucky junior rangers tagged along and learned how to catch and collect data safely from these amazing mammals. Read what one of them had to say in her article about the experience.

Series: Geologic Time—Major Divisions and NPS Fossils
The National Park System contains a magnificent record of geologic time because rocks from each period of the geologic time scale are preserved in park landscapes. The geologic time scale is divided into four large periods of time—the Cenozoic Era, Mesozoic Era, Paleozoic Era, and The Precambrian.

Updated Species Database Will Help Boost Amphibian Conservation Across the National Park Service
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.

Project Profile: Manage Invasive Plants in Northern Great Plains
The National Park Service will use an adaptive management approach developed with the U.S. Geological Survey to prevent, eradicate, and refine treatment methods for invasive grasses in the Northern Great Plains. The project aims to increase forage quality for bison and other wildlife, increase native plant diversity, improve pollinator habitat, increase climate resiliency, and refine restoration practices that can be broadly shared with other regions.
