Too often, wildlife are killed by cars or displaced because their habitat is divided by man-made roadways. In California, this issue is represented by the cougars of Los Angeles, some of which have been killed crossing the road. P-22, a male mountain lion and face of the #SaveLACougars campaign, is well-known in the region for his successful crossing of two major busy highways to reach his current home in the middle of Los Angeles.
As part of Urban Wildlife Week, Beth and a group of partners will hike for three and a half days through the Santa Monica Mountains and Los Angeles – taking a similar path to the one that P-22 may have followed.
Their journey, which can be tracked worldwide via urbanwildlifeweek.org, will illustrate how the promise of connectivity is integral not just for the future of mountain lions, but for wildlife as small as salamanders, birds and butterflies.
At the end of the hike, a free Urban Wildlife Festival will be hosted in Griffith Park. The event is free and open to the public — don’t miss the full schedule of activities, such as a virtual reality experience of a wildlife crossing, a Bioblitz Dance, a ranger lead walk, live music, delicious food, and more! We invite you to join the fun:

According to a National Park Service (NPS) study, the biggest threat to mountain lions in the Santa Monica Mountains is the loss and fragmentation of habitat byroads and urban development. Their long-term survival depends on their ability to move between regions to maintain genetic diversity and overall population health, but traffic-heavy roadways make this movement dangerous. Researchers have witnessed the deaths of twelve lions on the roadways in the area since the NPS study began in 2002.
Our key priority for this campaign is to advocate for the construction of a wildlife crossing over the Ventura Freeway at Liberty Canyon in Agoura Hills, linking protected habitat on each side of the freeway together. The bridge would resemble natural wildlife habitat and include features such as noise barriers and vegetation that would mitigate traffic noise, block light, and blend the overcrossing with the surrounding natural landscape.
The Liberty Canyon Wildlife Crossing, when built, will be the largest such crossing in the world, and a model for urban wildlife conservation.
The project enjoys widespread support and has been featured in media outlets across the globe. The #SaveLACougars icon, P-22, is the only known mountain lion to have successfully crossed two of the busiest freeways in America — the 101 and the 405 — and has earned celebrity status near his current home in Griffith Park, one of the largest urban parks in North America. P-22’s story has also earned him his own day in California on October 22, as well as sparked the first Urban Wildlife Week October 16- 22, 2016.
As part of Urban Wildlife Week, a diverse team of environmental advocates, scientists and leaders will retrace P-22’s historic 40-mile trek from the Santa Monica Mountains to his new home in Griffith Park. This unique wildlife walk, led by the Federation’s California Director Beth Pratt-Bergstrom, will showcase how Los Angeles is demonstrating worldwide leadership in urban wildlife conservation and point out vital connections that are still needed for both wildlife and people along the way.

Yet despite his remarkable journey, and his ability to adapt to a landscape dominated by humans, he still faces threats. He was recently sickened by rat poison and suffered from a bad case of mange. Fortunately, he was saved by biologists who trapped and treated him, restoring him from near death back to health.
Artist Wendy Pini has captured the spirit of hope symbolized by P-22’s recovery with the help of human intervention in an exclusive, limited edition print. She and her husband Richard Pini are the creators of the ground-breaking, New York Times bestselling comic series ElfQuest. Through her beautiful, sepia-toned illustration of P-22, Pini captures the message that mountain lions, and indeed all wildlife, can only have a strong future if humans care enough to protect them and their habitat.

The National Wildlife Federation’s #SaveLACougars campaign aims to build the largest wildlife crossing in the world over the busy 101 Freeway in P-22’s honor so his mountain lion kin — who might vanish from the area because of the same threats P-22 faces – can have a future in the Santa Monica Mountains. The crossing will also benefit countless other wildlife species struggling to survive in the greater Los Angeles ecosystem.
A limited number of signed 18 x 24 inch prints of Pini’s illustration are available exclusively through the Save LA Cougars shop. All proceeds from the sale of the print support the National Wildlife Federation’s #SaveLACougars campaign to make sure that P-22 and the mountain lions of the Santa Monica Mountains have a strong future.

National Wildlife Federation’s campaign to build a wildlife crossing over ten lanes of freeway at Liberty Canyon will provide safe passage for wildlife like mountain lions in this area. Meet a few of these cougars, read their stories and find out how you can help them survive among us!

P13’s homerange is the western end of the Santa Monica Mountains, from Malibu Creek State Park to Point Mugu State Park. She’s had at least two litters of kittens. Her father is also her grandfather – a first-order inbreeding event between a father and a daughter. (This happens because these mountain lions are so restricted and hemmed in.)
Died in 2011, at age 5
P18 dispersed from his mother’s home range in the Malibu Creek State Park area in mid-June 2011. He began slowly making his way east through the mountains. Within several months, he made his way east to Topanga State Park area. Likely in an effort to find a territory of his own, free of other males, he tried to cross the I-405 where he was hit by a car near the Getty Center.
5 years old
P18’s sister, she’s the only surviving mountain lion from the litter of kittens born to P13. In September 2012, P19 produced a litter of kittens, fathered by her father, P12. This is the second case of first-order inbreeding documented in the Santa Monica mountain lion population. The kittens, P23 and P24, show no obvious signs of health consequences associated with inbreeding.
~6 years old
This cat is quite the celebrity. He’s known as the Hollywood Lion, photographed by a National Geographic photographer with the famous Hollywood sign in the background. He miraculously survived crossing two of LA’s highly trafficked freeways in search of a new home and has taken up residence at L.A.’s Griffith Park.
He remains hemmed in by multiple freeways and has no opportunities for mating.
2 years old
One of four kittens born to P13 (mom) and P12 (father), biologists tracked her down when her mother started denning, meaning she confined her movements to a very small area. Two of her siblings died at a young age of abandonment.
Right now, she and her brother are traveling with mom.
Killed in 2015, not quite 2 years old
P32 was the first and only young male mountain lion known to have successfully crossed three highways and make it north out of the Santa Monica Mountains in search of new territory. He was struck by a car and killed while trying to cross Interstate 5 in August 2015.
P32’s story sadly illustrates the challenges mountain lions in this region face, particularly males.
8 years old
Weighing in at a solid 130 pounds, P41 is the first cougar to be fitted with a tracking device in the Verdugo Mountains, a 19-square-mile range that lies a few miles from the eastern end of the Santa Monica Mountains. He was just found this May!
Male cougars typically need up to 250 square miles, so biologists are looking to see if his territory includes the nearby southern San Gabriel Mountains, which would require crossing wide and busy Interstate 210.
2 months old
Born this summer, P43 was found under thick brush in a remote area near Malibu Creek State Park. Her mother is P23, who was memorably photographed about two years ago atop a dead deer on Mulholland Highway. Like most mountain lion cubs, she just began opening her beautiful blue eyes a short time ago!
2 months old
California’s new cougar, P44, lives in the Santa Susana Mountains and is the daughter of P35. Biologists aren’t sure yet which mountain lion is her father. She and P43 are the only single-kitten litters that federal biologists have documented locally since 2002.
Now she’s traveling with mom, learning how to hunt for food.
These treasured mountain lions and all wildlife living in the Santa Monica Mountains near Los Angeles need safe crossing between essential habitat areas to survive. National Wildlife Federation and our partners are advocating for a wildlife crossing at Liberty Canyon that would save the lives of countless wildlife.



For many, P32’s death served as another rallying point for the #SaveLACougars campaign, an effort lead by the National Wildlife Federation and our partner, the Santa Monica Mountains Fund, and supported by a large coalition and community of organizations, businesses, individuals and elected officials. The goal of the project, to build what could be the largest wildlife crossing in the world over the 101 Freeway at Liberty Canyon, is vital to ensuring a future for these remarkable animals.
The National Park Service has conducted research in the Santa Monica Mountains since 2003, and identified the Liberty Canyon corridor as a key area for mountain lions and other wildlife, and the ideal place for the crossing given it’s one of the last places with protected lands on both sides of the freeway. Jeff Sikich, one of the biologists working on the study, told National Wildlife, “Wildlife are great at telling us what areas are important to them. We have data points of cats going right up to the freeway and then turning around.”
Actor Rainn Wilson (The Office, Backstrom) voiced his support for this crossing in a new video, declaring “Let’s face it–LA traffic sucks even for cougars,” asking people to help with the cause. The video also stars NWF’s famous character Ranger Rick, along with the campaign’s poster child, P22, also known as the Hollywood lion and made famous by National Geographic photographer Steve Winter. P22 traveled from the Santa Monica Mountains and survived crossing two major freeways only to be trapped in a small urban park in Los Angeles, surrounded by roads.

The video also features some of the first images of the proposed crossing, as this week the Mountains Recreation and Conservation Authority (MRCA) released a ground breaking feasibility report by Caltrans that features the first conceptual designs and cost estimates. Earlier this year, NWF successfully applied on behalf of Caltrans for a seed grant from the State of California Coastal Conservancy (SCC), and they voted unanimously to grant $1 million to help fund the environmental assessment and engineering for the project.
As Rainn states, “Let’s give these animals the room they need to roam. Help save LA cougars—not the housewives, the mountain lions.”

]]>When people think of Los Angeles, the second largest city in the country, they are more familiar with the concrete-lined, nearly waterless ditches featured in famous movies like Transformers, Terminator 2: Judgment Day, and Grease. Yet Los Angeles has a river large enough to kayak through, and along this river’s 51 mile course, nature still abounds.
To highlight that the natural world is very much present on the LA River–indeed in all of Los Angeles–and to promote this weekend’s Urban Nature Fest at the Natural History Museum of Los Angeles County, we took two of the city’s wildlife celebrities, P22 and Ranger Rick, out for a kayak.
“Reading Ranger Rick magazine as a child was what helped me develop into the environmentalist and advocate I am today, said Superfisky. “Sharing the amazing story that nature can and does exist in our cities is essential, and what better place to tell the story of urban nature than on the LA River!”
As for the celebrity wildlife on the trip, both enjoyed their excursion. Although Ranger Rick did have to take a break from paddling around a 130 pound cat. P22 told reporters he conquered his fear of water in hopes of raising awareness for the #SaveLACougars campaign, which aims to build the largest wildlife crossing in the world on the 101 Freeway outside of LA to help save a population of mountain lions in the Santa Monica Mountains.
Said P22, “I think it shows how desperate I’ve become to allow a giant raccoon to paddle me up a river on a kayak so I can try to find a safe passage out of Griffith Park. I am not attempting those freeways again.”

Show your support for urban wildlife, and come meet Ranger Rick and “P22” at this weekend’s LA Urban Nature Fest at the The Natural History Museum of LA County!
Lila Higgins, Manager of Citizen Science at the Museum, is excited about this new event. “Over the course of this upcoming weekend, Angelenos will be able to come down to the museum and be steeped in the nature that lives with us in the city—from meeting the scientists who discovered 30 new species of flies in LA to checking out the new LA River Rover and making art about urban nature.”
Though a dating app like Tinder would help humans find love in the city, for poor P-22, Tinder would not yield any cougar love matches within Los Angeles’ Griffith Park. He is trapped within the confines of Los Angeles’ busy and dangerous highways with no mate in sight or in his foreseeable future. This is not the Hollywood ending the world wants!
So how can wildlife lovers play Cupid? Join National Wildlife Federation’s #SaveLACougars campaign. The campaign is aimed to create awareness for the plight of wildlife trapped by traffic and assist in the creation of a safe and beautiful wildlife crossing for the 101 Freeway at Liberty Canyon.

One plucky mountain lion somehow managed to cross the roads that ring the Santa Monica Mountains near Los Angeles. Incredibly, P22 made it across two freeways and has since been living in LA’s Griffith Park. Mountain lions like P22 should not have risk death by crossing busy freeways. The best chance for the survival of these Los Angeles cougars rests with the creation of a wildlife crossing—an overpass or tunnel—that will give them a way to avoid freeway traffic and safely travel between habitat areas.
The protected parklands in the Santa Monica Mountains near Los Angeles are filled with shrubland and mule deer—great habitat for mountain lions, but not nearly room enough for this wide-ranging species to survive. Each male needs a territory of about 200 square miles, which is probably why P22 braved the freeways to find a new home range! The mountain lions living in the Santa Monica Mountains need safe crossings that allow them to connect to habitat in the close by Simi Hills and Angeles National Forest.
Most wildlife living in patches of habitat in and near our urban areas eventually cross roadways to search out companionship, mates, food, shelter, and in some cases, to escape predators. Even the small spotted salamander need safe travels every spring when they leave their underground forest homes and migrate, often across high speed roadways, to wetland ponds to breed.
When wildlife populations are hemmed in by roads, they become smaller and more isolated. Over time, these isolated animals become susceptible to weaknesses from inbreeding and are more likely to be killed by predators or residential threats like poisoning, pesticides and traffic.
Canada’s Banff National Park has 44 wildlife crossings, and some animals seem to have definite preferences: grizzly bears, wolves, elk, moose and deer mostly choose crossing structures that are high, wide and short in length, while black bears and cougars tend to like long, low and narrow underpasses.
Creating a safe passage for wildlife in one of the last undeveloped areas on the 101 Freeway will give us a chance to ensure the future of cougars in the Santa Monica Mountains and Los Angeles area.
P22 and the dwindling numbers of mountain lions in the Santa Monica Mountains need our help—without a wildlife crossing, they could disappear altogether!

He journeyed through the second largest city in America in search of a home, crossing two of the busiest freeways—the 405 and the 101–in the country. Despite the average home range of a cougar being roughly 250 square miles, he makes do with only eight in a park surrounded on all sides by the city of Los Angeles. And even though his small territory of Griffith Park is visited by ten million people annually, he has remained largely out of sight.
Truly, it’s something to celebrate that the city that gave us Carmageddon also has allowed a mountain lion to thrive—until now.
I’ve been enthralled by this cat and his ability to survive in an urban setting since I first read about his arrival in Griffith Park in February of 2012. His plight—and the plight of all urban wildlife in the Los Angeles area—inspired me so greatly that I became involved in helping to support the research of the scientists on the Santa Monica Mountain Lion Study through my work with the National Wildlife Federation.
And until now, he has remained relatively safe, and perhaps more importantly, has given no indication he poses a threat to human safety as well. He spends the majority of his time in the natural and more remote areas of Griffith Park, dines predominately on mule deer, and lives up to his species nickname of “ghost cat” for being seldom seen.
Test results received last week confirm that P-22 has been exposed to anti-coagulant rodenticide, commonly known as rat poison, and is suffering from mange. The National Park Service (NPS) study has previously documented two mountain lion deaths as a result of rodenticide poisoning.
“Anti-coagulant rodenticides are designed to kill rodents by thinning the blood and preventing clotting,” said Dr. Seth Riley, an urban wildlife expert at Santa Monica Mountains National Recreation Area. “When people put these bait traps outside their homes or businesses, they may not realize that the poison works its way up the food chain, becoming more lethal as the dose accumulates in larger animals.”
Tests conducted by the California Animal Health and Food Safety Lab at UC Davis showed diphacinone and chlorophacinone in P-22’s blood, two first-generation anti-coagulant compounds. Recent legislation banned the retail sale of second-generation anti-coagulant rodenticides as of July 1, but does not impact the sale of diphacinone or chlorophacinone.
During nearly two decades of research in and around the Santa Monica Mountains, NPS scientists, working with UCLA graduate student Laurel Serieys, have documented widespread exposure to common household poisons in carnivores, sometimes leading to death. Of 140 bobcats, coyotes and mountain lions evaluated, 88% tested positive for one or more anti-coagulant compounds.
P-22 was captured in late March in order to replace the battery in his GPS collar. Noting his mangy appearance, biologists treated him with selamectin, a topical treatment for ectoparasitic diseases such as mange, fleas and ticks. Biologists hope the treatment is successful, but it remains unclear whether P-22 will fully recover.
After following P22’s adventures since the beginning, after joining in the effort to advocate for building a wildlife crossing for P22 and his kin, receiving this news of his exposure to poison came as a tragic blow. Just last month, I tracked P22 in Griffith Park with the amazing NPS researchers Seth Riley and Jeff Sikich, and stood within shouting distance of P22. I’ve lived and worked in Yellowstone and Yosemite, encountered wolves , bears, and bison in the wild, but standing on a hillside knowing P22 rested and listened as we talked nearby ranks as one of the best wildlife experiences of my life.
Los Angeles—and the rest of the world—now needs to prove to P22 his journey wasn’t for naught. Let’s give him—and all his Santa Monica Mountain kin—a Hollywood ending. He deserves as much.
UPDATE, MAY 22, 2014:
Some new photos and video footage of P22 show that the treatments the scientists gave him for mange and poison exposure may be working. I asked Jeff Sikich today about his condition, “It appears that he has gained some weight since his last capture. It is difficult to tell for sure from the photos but it seems that his face may look better but his tail is still thin. He continues to move around all the natural areas of GP and killing and eating his natural prey- mule deer.”
Our thanks to Griffith Park Connectivity Study and Miguel Ordeñana for the recent photo of P22 below.
National Wildlife Federation’s new partnership campaign with the Santa Monica Mountain Fund strives to ensure that mountain lions have a future in the Santa Monica Mountains, in part by helping to support vital research and by working to create a wildlife crossing at the 101 Freeway. NWF is proud to support this particular campaign and, more generally, to educate Californians and Americans everywhere about ways in which we can successfully co-exist with and even help wildlife prosper in an increasingly urbanized landscape.
As the National Park Service infographic states below, “National Park Service researchers have found a direct link between exposure to anticoagulant rodenticides, commonly known as rat poison, and the deaths of wildlife in and around the Santa Monica Mountains.”
