Only 165 New Mexico records exist for American bison, and just one names a specific place: Lincoln National Forest, in the south-central mountains. Carson National Forest and Coyote Creek State Park round out the picture as broader northern reference points, a genuinely thin record next to states like Wyoming and South Dakota, which each log thousands of bison sightings.

Reports turn up in most months and peak modestly in September, with a near-empty February. With so few total records, that shape says more about when someone happened to submit a sighting than about how bison actually move through the year.

New Mexico’s bison today largely descend from managed and reintroduced herds rather than a continuous wild population, which likely explains why records cluster around a handful of protected and ranched areas instead of spreading across the state’s grasslands. The species carries a global Near Threatened status from the IUCN.
