LOS ANGELES – A brand new examine from the College of California Davis reveals California mountain lions are being killed on roads and highways at excessive charges.
The information from the examine was revealed this week.
“The first findings are two-fold. One is that there are about one or two mountain lions per week which might be dying on state highways and there is in all probability extra on metropolis and county roads. The opposite is that there are these large regional clusters all through California within the Bay Space, Southern California and the Sierra Nevada foothills,” stated Fraser Shilling, the Director of the Highway Ecology Middle at UC Davis.
The numbers, exhibiting one to 2 mountain lions being killed every week on California roadways, are primarily based on knowledge between the years 2015 to 2022. The quantity has decreased through the years, however researchers imagine that may very well be as a result of a decline within the mountain lion inhabitants.
“If site visitors shouldn’t be altering and roadkill goes down, that is as a result of there’s fewer animals,” stated Shilling.
The information reveals mountain lions are being killed quicker than they’ll reproduce.
“In sure areas, they’re underneath menace of an area extinction. That is a very large deal as a result of in case you lose the highest predators in an ecosystem, the ecosystem begins to crumble,” stated Shilling.
A statewide mountain lion inhabitants estimate needs to be launched this 12 months. The final examine was carried out in 1996, in accordance with Shilling.
“After we take a look at a species like this, we won’t simply depend on 20-year evaluation intervals. Now we have to do assessments extra typically. Now we have to know what the developments are in these populations,” stated Shilling.
The examine additionally discovered a few of the most harmful locations for mountain lions to stay in Southern California.
“The locations they’re getting hit rather a lot are I-15, south of Temecula, the 210 close to Altadena, I-8 in San Diego County, Freeway 74 via Ortega Freeway [in the Santa Ana Mountains] after which Freeway 241 in Orange County,” stated Shilling.
Shilling believes there are answers that may assist curb the issue like fencing and wildlife crossings. The state is investing cash into creating extra fencing and crossings too, together with a wildlife crossing that’s being constructed over the 101 Freeway, close to Agoura Hills.
Nevertheless, Shilling stated there may be some issues with the crossings.
“If in case you have a inhabitants of mountain lions and so they’re divided by one thing like a freeway then they’re gonna be remoted from one another and you then get issues like we now have within the Santa Monica Mountains the place there’s inbreeding and also you get this general melancholy of the inhabitants as a result of they’re all associated to one another,” stated Shilling.
On Saturday on the Greek Theatre, individuals will honor P-22, the well-known mountain lion identified for wandering the hills close to the Hollywood Signal, with a memorial service. The service is offered out. Consultants imagine P-22 was hit by a automotive and suffered traumatic accidents earlier than euthanasia.
One other mountain lion, P-81, was additionally killed in January after specialists imagine the animal was probably hit by a car.
“P-22 and his loss of life may be an envoy and might characterize the issue to say we actually want to handle this, and we actually want to repair this,” stated Shilling.
