Trapping Mountain Lions Part 5: The Ghost Cat of the Santa Monica Mountains

For previous chapters on trapping mountain lions at the Grand Canyon, click here.

It was early and the light was low as the sun rose slowly over the Los Angeles basin--perfect for tracking. Usually a dense misty fog hung over the Santa Monica Mountains on mornings like this. But this was a clear, cool September morning. Just a few days before my birthday.And I was thrilled to be spending it here with Eric, wildlife capture specialist, coworker, and most importantly at the time- my boyfriend. We were looking for any signs of a mountain lion passing through this area and heading towards our trap.

He noticed the tracks first. They were crossing the wide, well-trodden trail we were following amidst foot prints and mountain bike tracks. Lions tend to prefer more cover than the trail could offer. We went off trail following the tracks, dropping into a steep drainage, heading down the mountain through the thick foliage. The Santa Monica Mountain range runs about 40 miles east to west from the Hollywood Hills in Los Angeles, to Point Mugu in Ventura County. The mountains form a barrier between the San Fernando Valley and the Los Angeles Basin, separating "the Valley" on the north and west-central Los Angeles on the south. I plowed my way through the thick mediterranean understory typical of this area, scrambling over rocks and under branches, deflecting them with my arms.

Eventually the drainage started to level out and the overstory opened up a bit. We followed a narrow game trail through the canyon bottom. Eric paused behind a large boulder, "Are you ready?" I nodded. We stepped around one side of the boulder to get a glimpse down canyon toward our trap, a foothold snare. There she was. The last female mountain lion in the Santa Monicas, and the first lion I'd ever seen in the wild. I was surprised at the red hue of her coat. Maybe it was the low light, maybe it was the distance. But she was beautiful.

She looked back at us, then turned her head away and tried to take a step forward, but stopped short. Her left front paw was in the foothold snare. She was P2, the second lion discovered to still be living in the wild urban island that is the Santa Monica Mountains. The first lion discovered, P1, was a large male, and the only other lion known to live inside the National Recreation Area. The math is simple. If P1 and P2 meet and hit it off, there will be more lions in the Santa Monicas. If not, it could be what biologists call a "local extinction," meaning the population would die out. Sure, its only one little population. But imagine that there could be additional local extinctions in other habitat islands throughout the county, the state, the country....and the bigger picture starts to come into focus.

P2 was wearing a GPS collar, but the battery was running low. We wanted to replace her collar so we could continue monitoring her movements and document her success or demise, whichever came first. We headed back up to the trail, then back to the truck. We didn't want to make her any more anxious than she was by hanging around, and we had to get the capture equipment ready. Eric made a few calls to round up the crew while we programmed the new collar. The rest of the team, along with some local press were soon on their way. Catching one of the last two lions in these mountains was no insignificant matter. The Santa Monicas are adjacent to the second largest urban metropolis in the U.S- Los Angeles. People around here are interested in how and where the lions are making a living in this urban-wildland interface. Are they crossing roads? Freeways? Passing through neighborhoods? Hunting along the highly-used trails? and When, exactly?

Historically, this kind of information has been hard to gather. Lions are supremely elusive. That's their niche, their job if you will. They hide. They glide through the landscape without a sound. They ambush their prey before it even knows they're there. Most people never see one, though they may come across tracks or old kills. Because of their stealth, they've been called the "ghost cat." But technology can shed some light on their habits. GPS collars send out precise locations stamped with the time and date to the biologists tracking the collared animals.

After waiting what felt like hours, the team was assembled. Together we headed back down toward the trapsite. It seemed further this time, the thick foliage made thicker by our heavy backpacks filled with the capture equipment we would need to sedate, collar, and document P2's capture. We crawled through patches of poison oak. Branches whipped my face and forearms in the backlash of the people ahead of me. One by one we gathered at the large boulder ahead of the trapsite and waited while Eric went ahead to assess the situation. The anticipation was palpable. For many, this would be their first lion. Those who'd assisted with the previous captures of P1 and P2 were just as anxious as the newbies. P2 and the hope she represented seemed to hold a special place in their hearts and minds.

We were dumbstruck when Eric came back shaking his head. The trap was empty. P2 had managed to pull her foot out of the snare while we were away. And just like that she was gone. I was in awe of her stealth and cunning, the sly cat that outsmarted us just when we were sure we had her. I'd just caught a glimpse of the "ghost cat" of the Santa Monicas.

  1. Great story, Emily. When did this take place? I know P2 was unfortunately killed by P1 back in 2005. Glad you had a chance to see her before then... and hopefully you'll come across their daughter. Thanks for sharing your experience :)

  2. This was way back in September 2003....thanks for reading!
