Mountain lions are a quiet success story in North American wildlife management, but their return across much of the U.S. has put people and big cats in closer proximity than many would have expected a generation ago. What looks like “rising encounters” is the result of stable or growing populations in core habitat, coupled with more people living, recreating, and working in wildland-urban interface zones where these animals travel, hunt, and disperse. Cougars don’t seek out humans, but they do follow their prey and exploit corridors of cover, and that means more reports and sightings these days.
Some of the newest patterns aren’t about exploding numbers as much as they are about cougars moving through landscapes they once inhabited before being extirpated. That’s why you’re hearing about increased mountain lion activity both in classic cougar country and in places where sightings were once rare. These aren’t all signs of dense, resident populations everywhere, but they are signals that mountain lion presence is changing across the country.
California
California has one of the largest and long-standing mountain lion populations in the United States, and state wildlife officials have noted increased sightings in areas where people and lions share space. California’s landscape — from the Sierra Nevada to the coastal ranges and foothills — provides extensive cougar habitat, and protections under the California Wildlife Protection Act have helped sustain these populations.
The rise in reported encounters isn’t simply a population surge. It’s tied to the fact that humans are living and recreating more in wildland-urban interface zones, where lions travel between fragments of habitat. Sightings on trails, in ridge top suburbs, and near parks are more common than they were decades ago. That overlap hasn’t made cougars dangerous, but it has made them more visible, especially on camera traps and trail cameras near deer habitat — the prey that draws them inland and closer to people’s backyards.
Colorado
Colorado’s mountain lion presence has been significant for decades, with rugged forests and foothills supporting healthy populations across much of the state. Sightings and reported encounters have risen in recent years, which reflects both stable cougar numbers and a rise in outdoor recreation in lion habitat.
Hunters, hikers, and trail runners are spending more time in areas where mountain lions live, and that overlap increases the number of observed cougars. Deer and elk — the lions’ primary prey — are abundant within Colorado’s big game range, drawing cougars into areas that humans also frequent. This doesn’t necessarily mean wolves or lions are overpopulating, but it does mean cougars are present in places where people are more likely to see them. Wildlife managers cite these patterns as part of living with healthy big cat populations in the Mountain West.
Oregon
Oregon’s Cascade and Coast Range forests, along with other wildlands, support a large mountain lion population, and encounter reports have become more familiar to local land managers and recreationists. As trail use has increased across the state’s public lands, sightings and tracked movements have followed.
Cougars in Oregon aren’t rare, but they’re showing up on trail cameras and in public reports more often than in prior decades. That’s partly because hunters, hikers, and mountain bikers are putting more miles on forested trails where lions follow deer. Many of the sightings are in areas that historically saw less human traffic, making these encounters feel new even though the animals have long been there. For people living near forest edges and foothills, seeing a cougar sign or camera capture has become a realistic part of outdoor life.
Washington
Mountain lions occupy a broad swath of Washington’s landscape — from the Cascades to foothills and river corridors — and many long-time outdoor users say sightings have climbed as public lands draw more visitors. Stable populations combined with increased trail use mean more eyes on cougars than in previous generations.
Washington’s Department of Fish and Wildlife notes that sightings, tracks, and trail-cam images are reported more often, not because lions are suddenly crowding towns, but because people are spending more time in traditional cougar habitat. That overlap creates opportunities for encounters where they used to be rare. These reports aren’t evidence of aggressive behavior, but they do reflect a changing pattern of human–big cat interface in backcountry zones often shared by deer and elk.
Idaho
Idaho’s mountain lion population is well established across much of the state’s forested mountains and river valleys, and sightings have become more common near rural communities and popular backcountry routes. Cougar presence isn’t new here, but as people explore deeper into prime habitat, reports follow.
Mountain lions in Idaho tend to track deer and elk herds, and as those ungulates seasonally shift into foothills and lower elevations, cougars follow. At the same time, more hikers and hunters are using these same zones, which leads to sightings that didn’t get documented as often in the past. Wildlife agencies still emphasize that cougars steer clear of people whenever possible, but the rise in encounters reflects increased overlap in landscape use rather than sudden population explosions.
Montana
Montana supports strong mountain lion numbers, particularly in the west and central regions where habitat and prey are abundant. Sightings and reports of encounters have been climbing in step with rising outdoor use of forested and high mountain terrain.
The state’s expansive habitat draws hikers and hunters into areas long occupied by cougars, so more reports arise simply because more humans are present during times when lions are active. These sightings are most common on trails and near winter range, where deer and elk congregate and cougars follow behind. Managers often describe this pattern as part of living with healthy big cat populations: lions aren’t rare, they’re just rediscovered by people in more places than before.
Utah
In Utah, mountain lions are widespread across both high mountains and desert canyons, and sightings near trailheads and rural communities have become more frequent in recent years. Wildlife officials attribute part of this to the spread of cameras and more residents in cougar habitat.
Utah’s deer populations remain strong, and that draws cougars into areas with abundant prey. Combine that with more people moving into foothill regions and more recreation on public lands, and the number of reported encounters rises. Some of the “increase” is simply documentation — cameras and smartphones make sightings more likely to be reported. Still, the trend reflects lions using territory near developed edges more often as deer and other prey push lower in drought or seasonal conditions.
Arizona
Arizona’s rugged mountains and plateaus have long supported healthy cougar populations, and reports of sightings and tracks near habitat edges appear to be more common with expanding human use of those same areas.
Mountain lions here follow mule deer and bighorn sheep across steep terrain, and when those prey animals move lower in search of forage or water, cougars follow. Outdoor recreation in canyons and high country has increased, and that overlap means encounters are more visible than they were a generation ago. Wildlife managers stress that sightings don’t necessarily signal population spikes, but they do show that cougars occupy broader parts of their historical range — and interact with people more often as both use similar landscapes.
Nevada
Nevada’s mountain lions live across mountain ranges and brushcountry where deer are common, and sightings — especially on trail cameras — seem to be reported more often than they once were. Many rural residents and recreationists now expect occasional cougar sightings in areas that were once seldom checked.
This pattern isn’t surprising given how cougars travel in search of deer and other prey across Nevada’s vast habitat patches. Outdoor activity in backroads, foothills, and foothill ranchlands has widened, meaning sightings happen in places people didn’t travel to as often decades ago. State wildlife officials continue to emphasize cougar ecology and safety, but they also acknowledge that opportunistic reporting and camera traps make “rising encounters” easier to track.
New Mexico
New Mexico’s rugged habitat — from basins to high country — supports a vibrant mountain lion population that has been stable or increasing in many areas. Sightings near trails and rural communities have grown more frequent as recreational use expands and people live closer to lion habitat.
Mountain lions follow deer and elk across canyons and slope country, and that brings them near watershed trails and campgrounds where hikers and hunters are active. Reports often spike in fall and winter when prey movements bring lions lower in elevation. Like in other western states, the trend reflects more overlap between lions and people rather than a sudden surge in numbers — making encounters feel more common because more people are present.
Nebraska
Nebraska once lacked confirmed mountain lion populations, but sightings have risen in its Pine Ridge and western regions thanks to lions dispersing from established ranges in the Dakotas. Scientists and wildlife officials note that cougars have recolonized these areas and shown signs of resident animals over time.
These aren’t huge populations yet, but the fact that sightings and reports are happening reliably is new. Lions are moving into habitat that’s suitable for them, and confirmed photos or tracks now crop up where people never expected them. That trend represents the frontier of cougar range expansion, and local land managers are paying attention as sightings cluster more often around natural corridors.
Kansas
Kansas doesn’t have a breeding mountain lion population yet, but confirmed sightings and photo evidence have risen in pockets of the state, particularly near forested western and central counties. These records tend to involve transient animals dispersing from core cougar ranges rather than a local established population.
Wildlife officials have documented cougars traveling through multiple counties in recent years, and trail cameras have captured more verified images than in the past. While a permanent resident round is not established, these transient sightings show that mountain lions are exploring farther than they once did. That’s a shift from historical absence and signals changing patterns in how these big cats use landscape corridors across the Plains.
Minnesota
Minnesota has seen confirmed mountain lion sightings and trail camera photos in its northern forests where cougar habitat exists, even though no resident breeding population is established (yet). These reports are rising compared to historical norms, largely from transient lions moving out of core western ranges.
These sightings reflect the same dispersal dynamics seen in the Plains and Midwest. Young males range widely in search of territory and mates, and Minnesota’s landscape attracts them occasionally. That means more reports, more photos, and more people encountering evidence of these cats where they weren’t seen for decades. It’s not a sign of a booming population, but it is a sign of lions testing habitat that could support them.
Michigan
Michigan has logged record confirmed mountain lion sightings in 2025, continuing a multi-year upward trend in report numbers. According to the state DNR, the count of confirmed sightings has climbed steadily over several years, even as officials clarify that a permanent breeding population hasn’t been established.
Most of these detections involve transient animals likely roaming from western ranges, but the fact that sightings have increased year after year is notable. It reflects broader patterns of cougars dispersing eastward and appearing in reclaimed or suitable forest habitats. Landowners and outdoor users across Michigan now routinely report sightings in northern counties, which is a marked change from a century when cougars were absent from the state.
Missouri
Missouri has a growing number of confirmed mountain lion sightings in recent years, especially in forested and rugged regions where lion habitat persists. Biologists and land managers note that lions dispersing from western populations are showing up more often than they did historically.
Even though confirmed evidence remains rarer than reports, repeated trail camera images and track verifications point to cougars moving through the Ozarks and adjoining landscapes. That trend fits the broader pattern of range expansion from core western ranges into midcontinental terrain. Missouri doesn’t yet host a known breeding population, but the rise in sightings — especially of transient animals — illustrates how mountain lions are exploring farther east than they have in decades.
