Agate Fossil Beds National Monument, located in the Niobrara River drainage in northwestern Nebraska, was established to preserve and protect its significant Miocene epoch fossil deposits and to interpret its cultural importance as a meeting place for many native tribes. In addition to the fossils, unique natural resources in the park include its extensive native prairies, the Niobrara River and associated wetlands, and its scenic vistas and natural soundscapes. More information about Agate Fossil Beds' natural resources may be found through the park's Nature and Science webpage.

The park's ungrazed prairie provides diversity within a landscape grazed by cattle. However, this proximity to ranchland raises concerns about invasive exotic plants and degraded water quality. Other natural resource concerns include the absence of fire and natural grazing, and altered river flows within the Niobrara.
