Mountain lion tracks continue appearing across public lands in 15 states

Mountain lion tracks are appearing on snowfields, sand washes, and prairie mud across a widening swath of the United States, signaling a big cat quietly reclaiming ground it lost more than a century ago. From the Pacific coast to the Great Plains and parts of the Midwest, physical evidence and confirmed sightings now stretch across at least 15 states, reshaping how agencies manage public lands and how people move through them. At the same time, new protections in some regions and rising conflict reports in others show how uneven and contested this return has become.

Biologists describe a predator that is both remarkably adaptable and intensely secretive, able to slip through suburbs at night and cross busy highways if given even a narrow corridor. The spread of tracks and trail camera images points not to a sudden invasion but to a slow, generational expansion that began decades ago and is now reaching more farms, parks, and hiking trails than many residents ever expected.

From coast‑to‑coast cat to fragmented survivor

Mountain lions once ranged across the entire continental United States, from Atlantic forests and Gulf wetlands to snow‑covered peaks in the West. Conservation groups note that these big cats historically occupied habitat from desert scrub to high alpine terrain, with a presence that matched the full breadth of the modern United States. Systematic persecution, bounties, and habitat loss in the 19th and early 20th centuries wiped out most eastern populations outside of a small enclave in Florida and pushed western lions into rugged strongholds where people were fewer and livestock losses were easier for ranchers to monitor.

By the late 1900s, surviving core populations were concentrated in the Rocky Mountains, the Southwest, and parts of the Pacific coast, with isolated groups hanging on in places like the Florida panther stronghold. That contraction set the stage for the current expansion. As hunting regulations tightened, deer herds grew, and some rural areas lost people, young dispersing lions began pushing out of those strongholds again, leaving tracks and scat in river bottoms, on logging roads, and around the edges of new housing developments.

Western strongholds and the Pacific spine

The most stable and visible mountain lion populations still run along the spine of the West, where large blocks of public land give the cats room to roam. In states such as California, lions prowl coastal ranges and interior mountains, often crossing between national forests, state parks, and urban greenbelts. Farther inland, rugged terrain and big game herds in places like Colorado and New Mexico support some of the highest densities of lions in the country, and hunters, hikers, and ranchers regularly encounter tracks on public lands.

Along the Pacific Northwest, cats follow forested ridges and river corridors in Oregon and into neighboring Washington, where dense timber and steep valleys create ideal stalking cover. Habitat models and population tables, such as the recent overview of Mountain Lion Population by State 2026, consistently show western states holding the largest minimum populations, with estimates climbing into the thousands where protected habitat and prey are abundant.

Prairie ghosts on the Great Plains

Far from the mountains, a quieter story is unfolding on the grasslands. For more than 20 years, biologists and ranchers have documented mountain lions moving east into the Great Plains, padding along river breaks and shelterbelts that cut through open country. Reporting from the region describes how these cats now show up in places that look more like an African savanna than a traditional mountain lion postcard, with one account likening their spread across the Great Plains to predators on the Serengeti in Africa as lions adapt to prairie deer and antelope rather than forest elk.

In Wyoming and neighboring plains states, sightings on prairie dog towns and in wide, rolling pasture have become frequent enough that some locals talk about “prairie mountain lions” as a distinct presence. Coverage of this shift notes that mountain lions have been expanding their range into the Great Plains states for more than 20 years, a trend that has accelerated as young males strike out from crowded western ranges and find enough cover and prey to survive in landscapes once thought too open for them. Tracks along fence lines, creek bottoms, and even center‑pivot irrigation corners now confirm that public and private lands on the plains are part of the species’ new frontier.

Midwestern comeback: Kansas and beyond

The most concrete evidence of eastward expansion comes from state agencies that track and verify each sighting. The Kansas Department of Wildlife and Parks reports that mountain lions have been confirmed in 50 of Kansas’s 105 counties, including places such as Allen and Atchison that sit far from the Rocky Mountain core. According to Kansas Department of, those confirmations now include photos, tracks, and carcasses in cropland, grassland, and wooded stream corridors, a clear sign that lions are using modern agricultural mosaics as travel routes.

Regional advocates who compile reports from multiple states point out that the Midwestern states are now receiving dozens and dozens of confirmed cougar sightings from expanding western populations. One information library focused on big cats notes that this pattern means mountain lions now exist outside of the Florida population in a growing cluster of Midwestern landscapes, with verified animals in states that had not seen resident cougars in generations. The spread of tracks across Kansas, Nebraska, South Dakota, and neighboring states suggests that what started as rare dispersers has evolved into a persistent trickle of lions moving through and, in some cases, lingering long enough to hunt regularly on public lands.

Michigan’s record detections and the upper Midwest

Nowhere is the shift more striking than in the upper Midwest, where cougars were wiped out in the early 1900s. In Michigan, state wildlife officials report that confirmed cougar sightings have doubled over the last three years, a change that reflects both improved detection and a genuine increase in animals moving through the state. Coverage of the trend notes that the DNR has verified more photos, tracks, and trail camera clips in that period than at any time since the start of the 20th century, signaling that the big cats are once again leaving a clear imprint on forests and wetlands in Michigan.

Additional reporting highlights that cougars have been detected 31 times in Michigan in 2025, the highest number since they were wiped out in the early 1900s, and that some of those detections include cubs. One account by LAURA HERBER explains that these 31 detections include trail camera images and verified tracks that suggest at least one female is raising babies in Michigan, which would mark a transition from transient visitors to a breeding presence. Video coverage from early 2026 reinforces that Michigan saw a record number of cougars in 2025, and together these reports show that the upper Midwest, including nearby states such as Wisconsin, Minnesota, and even Illinois, is now firmly on the map for big cat watchers.

Florida’s isolated panthers and the 15‑state picture

While western and Midwestern lions are reconnecting across large landscapes, the Southeast tells a different story. In Florida, the only recognized population of the endangered Florida panther remains confined to a relatively small area of south and central parts of the state, hemmed in by highways, development, and wetlands. A search snapshot for Florida underscores how distinctive this population is compared with the western lions that are recolonizing the Great Plains and Midwest.

Conservation groups that track the species point out that mountain lions are now primarily found in 14 western states with a separate, isolated group in Florida, which together make up the core 15‑state footprint that still has resident or regular mountain lion presence. That list includes western strongholds such as Arizona, Utah, Nevada, Idaho, Montana, Wyoming, Oregon, Washington, California, Colorado, New Mexico, and Texas, plus expanding territories in the Great Plains and upper Midwest and the Florida panther enclave. The combined picture is of a species that is no longer confined to remote mountains but still faces sharp regional differences in connectivity and long‑term security.

California’s new protections and wildlife crossings

Nowhere are those regional differences more visible than in California, where mountain lions live in close proximity to tens of millions of people. Earlier this year, the California Fish and Game Commission found that protections under the California Endangered Species Act are warranted for southern California and central coast mountain lion populations. The official announcement from California Fish and explains that these protections respond to threats such as habitat fragmentation, vehicle strikes, and genetic isolation in places like the Santa Monica and Santa Ana mountains.

Parallel reporting notes that state leaders moved ahead with these protections after federal officials declined to list the same populations, with one account describing a mountain lion walking in the Santa Monica Mountains National Recreation Area near the Los Angeles and Ventura County line as a symbol of the debate. A related project, The Wallis Annenberg Wildlife Crossing, is now under construction over the 101 Freeway in Agoura Hills, a structure designed to reconnect the Santa Monica Mountains population with habitat to the north. Coverage of the project, sometimes referred to as The Annenberg crossing, emphasizes that the 101 crossing is meant to reduce roadkill and restore gene flow for lions that have been trapped on an island of habitat by decades of freeway construction.

Growing encounters in Texas and the interior West

As populations expand and people spend more time on trails and backroads, direct encounters are becoming more frequent. A recent compilation of incidents describes 11 cases of mountain lion encounters across the United States, including a string of sightings in North Texas where residents found tracks near neighborhoods and along popular recreation spots. In North Texas, these reports have prompted renewed debate about how the state classifies and manages mountain lions, which currently receive far fewer protections than in places like California.

Search summaries for Texas and neighboring interior western states such as Arizona, Utah, Nevada, and New Mexico show that lions occupy a wide variety of public lands, from desert canyons to pine forests. In many of these regions, hunting seasons and depredation permits remain the primary tools for managing conflict, even as suburban growth pushes more people into lion habitat. The result is a patchwork where a hiker in Colorado or New Mexico might see educational signs about living with mountain lions on national forest trails, while a rancher in Texas might view the same animal primarily as a livestock threat.

Public safety, warnings, and the path ahead

The spread of tracks into new counties and states has prompted a wave of public safety messaging. In Washington, for example, the Washington Department of Fish and Wildlife recently received reports of numerous sightings of a wild predator in an unexpected suburban setting and responded with warnings about how to behave if residents encounter a lion. According to The Bellingham Herald summary, officials stressed keeping pets close, avoiding running if a lion is spotted, and reporting any aggressive behavior immediately so wardens can respond.

Across the 15 states where mountain lions now leave regular sign, agencies and advocates are trying to balance the ecological benefits of a top predator with the real anxiety that comes when tracks appear near playgrounds or backyard trails. Education campaigns in states like Oregon, Colorado, and California encourage people to travel in groups, keep children close, and secure attractants such as backyard deer feeders, while habitat projects like The Wallis Annenberg Wildlife Crossing aim to steer lions toward safer routes. The next decade will likely determine whether the recent surge in tracks and sightings becomes a stable, connected population across much of the country or fragments again under the pressure of roads, development, and conflict on the edges of public land.
