The U.S. National Wildlife Refuge System (NWRS) was established in 1903 to conserve lands and waters essential for fish, wildlife, and habitats. Today, the NWRS encompasses 574 units across the United States, providing essential habitats for many species of conservation concern like pikas (Ochotona spp.). However, despite their monitoring importance on NWRS lands, no system-wide assessment has evaluated pika occurrence or status across refuges. Although pikas occupy relatively few refuges, these areas may serve as important refugial habitats amid global change. Here, we summarize known occurrences of American pikas (O. princeps) in the western United States and collared pikas (O. collaris) in Alaska on or adjacent to refuges. Using refuge biogeographic data and published observations, we identify where pikas are currently known, where suitable habitat exists, and where apparent declines may be occurring. Results highlight refuges that could serve as long-term monitoring sites and guide management actions to sustain pika populations under changing conditions. This assessment provides a foundation for future research and collaboration across the broader pika network. Understanding pika distribution within the NWRS informs adaptive management and underscores the role of refuges in conserving species highly sensitive to environmental change.
