Los Angeles and Mumbai, India, share many superlatives as pinnacles of cinema, style, and site visitors congestion. But one other similarity lurks within the shadows, most frequently seen at night time strolling silently on 4 paws.

These metropolises are the world’s solely megacities of 10 million-plus the place massive felines—mountain lions in a single, leopards within the different—thrive by breeding, looking and sustaining territory inside city boundaries.
Long-term research in each cities have examined how the massive cats prowl by their city jungles, and the way individuals can finest reside alongside them—classes which may be relevant to extra locations in coming many years.
“In the long run, there’s going to be extra cities like this, as city areas additional encroach on pure habitats,” mentioned biologist Audra Huffmeyer, who research mountain lions on the University of California, Los Angeles. “If we need to hold these massive carnivores round on the planet, we’ve got to study to reside with them.”
FREEWAYS AND FRAGMENTED HABITAT
Twenty years in the past, scientists in Los Angeles positioned a monitoring collar on their first cat, a big male mountain lion dubbed P1, that defended a large swath of the Santa Monica Mountains, a coastal vary that lies inside and adjoining to the town.
“P1 was as large as they get in southern California, about 150 kilos,” mentioned Seth Riley, a National Park Service ecologist who was a part of the trouble. “These dominant males are those that breed—they will not tolerate different grownup males of their territory.”

With GPS monitoring and digicam traps, the scientists adopted the rise and fall of P1’s dynasty for seven years, by a number of mates and litters of kittens. “2009 was the final time we knew something about P1,” mentioned Riley. “There should have been a struggle. We discovered his collar, blood on a rock. And by no means noticed him once more. He was moderately outdated.”
Since then, Riley has helped collar round 100 extra mountain lions in Los Angeles, constructing an enormous database of lion conduct that is contributed to understanding how a lot territory the cats want, what they eat (largely deer), how typically they cross paths with individuals and what might imperil their future.

As with medieval European kings, the largest risk turned out to be inbreeding. Living in small territories separated by highways has prompted some males to mate with daughters and granddaughters, who weren’t capable of naturally disperse farther away. That’s led to genetic issues similar to fertility points and kinked tails.

“Based on genetic evaluation, we all know that P1 mated with P6, his daughter—that was the primary case we documented of this very shut inbreeding,” mentioned Riley.
LEOPARDS IN URBAN LANDSCAPE
In Mumbai, one of many world’s most densely populated cities, the leopards are packed in, too: about 50 have tailored to an area ideally suited to 20. And but the nocturnal cats additionally hold largely out of sight.
“Because these animals are so secretive, you do not know a lot about them. You cannot simply observe them,” mentioned Vidya Athreya, director of Wildlife Conservation Society in India and a part of a analysis crew that just lately fitted 5 leopards with monitoring collars.
The leopards’ core vary is centered round Sanjay Gandhi National Park, a protected space boxed on three sides by an urbanized panorama, together with a neighborhood that is dwelling to 100,000 individuals and practically a dozen leopards.

Researchers tackled particular questions from park managers, similar to how the cats cross busy roads close to the park.
To get the reply, they collared a giant male dubbed Maharaja. They discovered that it walked largely at night time and traversed over 60 kilometers (37 miles) in a couple of week, from the park in Mumbai to a different close by. The leopard crossed a busy state freeway, utilizing the identical spot to go, on three events. It additionally crossed a railway observe.
The path chosen by Maharaja is close by a brand new freeway and a freight hall underneath development. Researchers mentioned that realizing the massive cats’ freeway crossing habits might help coverage makers make knowledgeable choices about the place to construct animal underpasses to scale back accidents.
LIVING ALONGSIDE BIG CATS
In Los Angeles, long-term mountain lion analysis exhibiting the hurt of fragmented habitat helped gas a profitable marketing campaign to construct a wildlife crossing bridge over U.S. Route 101, one of many metropolis’s busiest freeways. Construction started on April 22.

When it is completed in three years, the bridge shall be coated in native crops and embody particular sound partitions to reduce mild and noise disturbances for nocturnal animals. It will join Santa Monica Mountains and Simi Hills, enlarging the relationship pool for resident mountain lions.
But studying to reside alongside cats shouldn’t be solely a matter of infrastructure choices, but in addition human decisions and schooling.
When Athreya first began advocating for co-existence with Mumbai’s leopards, she was met with skepticism and pushback from different biologists and coverage makers. They thought it could be unattainable for large cats to reside alongside individuals with out vital friction, or worse.
“The dominant narrative was about battle,” she mentioned. But she helped push the dialog to be about “negotiations, bettering the state of affairs for each wildlife and other people.”

That is to not say dwelling alongside a giant predator is with out perils. In Mumbai, Purvi Lote noticed her first leopard when she was 5, on the porch of a relative’s dwelling. Terrified, she ran again inside to her mom. But now the 9-year-old says she is not as afraid of the massive cats.
Like different kids, she does not step open air alone after darkish. Children and even adults journey in teams at night time, whereas blaring music from their telephones to make sure that leopards aren’t shocked. But essentially the most basic rule, in accordance with the teenager: “When you see a leopard, do not trouble it.”
AVOIDING DEADLY CONFLICTS
Leopards in Mumbai tailored to primarily hunt feral canines that frequent rubbish dumps outdoors the forest and largely attacked individuals when cornered or attacked. But in 2010, 20 individuals in Mumbai died in leopard assaults, mentioned Jagannath Kamble, an official at Mumbai’s protected forest.

The turning level was the conclusion that the understaffed forest division could not simply hold reacting to particular person assaults by capturing and transporting leopards to forests since they returned. Instead, it determined to deal with making an attempt to get individuals to coexist with the predators.
Officials roped in volunteers, nongovernmental teams and the media for a public schooling program in 2011. Since then, fatalities have dropped steadily and nobody has been killed in an assault since 2017.
The final recognized sufferer was Muttu Veli’s 4-year-old daughter Darshini. Veli, an workplace employee who got here to Mumbai in 1996, mentioned Darshini was taking part in outdoors their dwelling in a slum on the fringe of the forest and he or she simply did not return dwelling. Eventually, her mauled physique was recovered.
“My daughter is gone. She will not come again,” he mentioned.
