LOS ANGELES (CNS) - A report released Thursday shows that fewer wild animals have been struck by vehicles in three states during shelter-in-place orders, with the number of mountain lions killed in Southern California and elsewhere in the state declining by more than 50%.Researchers at the UC Davis Road Ecology Center determined that 56% fewer mountain lions were killed in California between the 10 weeks before the stay-at-home orders compared with the 10 weeks after, with the number of large wild animals being killed by vehicles falling 21% from 8.4 per day to 6.6 a day."The reduction in numbers of wildlife killed is surprising, and is a silver lining for both wildlife and people at this difficult time," said Winston Vickers, who directs the California Mountain Lion Project, a program of the Karen C. Drayer Wildlife Health Center in the UC Davis School of Veterinary Medicine."For Southern California mountain lions, even one lion making it across a road instead of being killed can be very significant for populations like the ones in the Santa Monica or Santa Ana mountain ranges," Vickers said.The UC Davis researchers analyzed traffic and collision data collected from California, Idaho and Maine, which have advanced systems for tracking wildlife-vehicle conflict. The study provides the first evidence that wildlife- vehicle conflict decreased along with reduced vehicle travel during the response to the COVID-19 pandemic, said Road Ecology Center director Fraser Shilling."There is a statistically significant decline in wildlife deaths on highways in all three states following reductions in traffic this spring," Shilling said. "This has not been the case for any of the previous five years for these three states. If anything, there is usually an increase in spring."If it continues, the respite could amount to about 5,700 to 13,000 fewer large mammals being killed each year in the three states, and 50 fewer mountain lion deaths per year in California, he said.The positive impacts noted in the report "are likely to be just the tip of the iceberg of reduced deaths of wildlife on U.S. roads and highways," given the under-reporting of large animals involved in collisions with vehicles and the lack of systematic reporting of smaller animals killed on roads, Shilling wrote.He plans to continue to watch closely for impacts to wildlife given a two-to-three-fold increase in traffic in recent weeks as states reopen their economies.Shilling noted "the clear link between traffic and rates of mountain lion death," and said puma populations must be protected from traffic, especially in Southern California and the Bay Area, to reduce mountain lion mortality.In a unanimous decision in April, the California Fish and Game Commission moved a step closer to protecting six struggling mountain lion populations, including those in the Santa Monica and Santa Ana mountains, under the state's Endangered Species Act.The commission's decision cleared the way for a yearlong review on whether the six populations of mountain lions should be formally protected under the state act, with the act's full protections applying during the yearlong candidacy period.Supporters are seeking "threatened species protection" -- which is designed to protect species that at risk of extinction in the foreseeable future without improved management -- involving the "most imperiled populations" of mountain lions in California, according to Tiffany Yap, a biologist at the Center for Biological Diversity and primary author of the petition.Researchers with the National Park Service, UC Davis and UCLA warn that if enough inbreeding occurs, the Santa Ana population could go extinct within 12 years, and the Santa Monica population within 15 years.The state Department of Fish and Wildlife had recommended the move shortly after P-56, a male mountain lion in the critically endangered Santa Monica population, was killed in January under a state-issued depredation permit by a landowner who had lost livestock to the big cat.Planning and fundraising is underway for a wildlife crossing over the 101 Freeway in the Liberty Canyon area of Agoura Hills that would provide a connection between the small population of mountain lions in the Santa Monica Mountains and the large and genetically diverse populations to the north. 4335

LOS ANGELES (AP) — Three out of four Americans favor requiring people to wear face coverings while outside their homes to help slow the spread of the coronavirus, including a solid majority of Republicans. That's according to a new poll from The Associated Press-NORC Center for Public Affairs Research. Support for wearing masks is overwhelming among Democrats, while 58% of Republicans say they back such policies. As coronavirus cases rise, about half of Americans now say they're extremely or very worried about themselves or family members becoming infected. The poll also finds that about two-thirds of Americans disapprove of how President Donald Trump is handling the outbreak. 693

LOS ANGELES (CNS) - Los Angeles County will once again prohibit dining at restaurants and bars beginning Wednesday, as the recent spike in COVID- 19 has brought the five-day average of new cases to more than 4,000, health officials said Sunday.To reduce the possibility for crowding and the potential for exposures in settings where people are not wearing their face coverings, the county's Health Officer Order will be modified so that restaurants, breweries, wineries and bars will only be able to offer take-out, drive thru, and delivery services.The order will apply for a minimum of three weeks.Officials warned of the possibility of such measures last week, as new cases and hospitalizations continued to surge in Los Angeles County and statewide. They follow a statewide "soft curfew" that went into effect Saturday prohibiting all "nonessential work, movement and gatherings" between 10 p.m. and 5 a.m., continuing until the morning of Dec. 21.On Sunday, the Los Angeles County Department of Public Health reported 2,718 new cases of COVID-19 and nine additional deaths, bringing the county's totals to 364,520 cases and 7,438 fatalities. The previous three days had each seen more than 4,000 cases reported, including a single-day record of 5,031 cases on Thursday.If the five-day average of cases grows to 4,500 or more or hospitalizations are more than 2,000 per day, a Targeted Safer at Home Order will be issued for three weeks, the health department said. That order would offer additional restrictions while allowing essential and emergency workers and those securing essential services to leave their homes.The number of county residents hospitalized with the virus increased from 1,391 Saturday to 1,401, with 26% in intensive care. That's more than double the daily number in the beginning of October, when it was under 700.The department reminded everyone to stay home as much as possible for the next two to three weeks to change the trajectory of surging cases and save lives, and repeated its advice that people not travel for the upcoming Thanksgiving holiday."As we modify our Thanksgiving holiday celebrations, we are reminded of the many families who will miss their loved ones who have passed away from COVID-19. We send wishes for healing and peace," County Health Director Barbara Ferrer said."The persistent high number of cases requires additional safety measures that limit mixing in settings where people are not wearing masks. We hope individuals continue to support restaurants, breweries and wineries by ordering for take-out or delivery. We also fervently hope every L.A. County resident supports all our businesses by following the Public Health directives that we know work to slow spread. Unfortunately, if our cases and hospitalizations continue to increase, we will need to issue further restrictions to protect our healthcare system and prevent more deaths."Other restrictions that took effect Friday were:-- indoor "nonessential" businesses such as retail stores, offices and personal care services will be limited to 25% occupancy;-- outdoor cardrooms, miniature golf sites, go-kart tracks and batting cages will be limited to 50% of maximum outdoor capacity;-- customers at personal-care businesses must make advance appointments, and no services that require customers to remove their face masks can be offered; and-- outdoor gatherings must be limited to no more than 15 people from a maximum of three households.The county previously issued guidance limiting gatherings to three households, but there was no numerical limit on attendees.Dr. Mark Ghaly, California's Health and Human Services secretary, said the state's order was not a hard curfew, indicating that people can still go outside of their homes, but they just shouldn't gather with others. He noted that he still plans to take his dog on its normal 11 p.m. walk.He said there is no definitive cause for the state's sudden surge in cases."There is no single culprit," Ghaly said. "It's a combination of factors. It's certainly the colder weather, more mixing, which comes with more opening. ... And of course greater travel. We've enjoyed some events over the last many weeks -- in my home county of Los Angeles, the Dodgers, the Lakers. We had Halloween. We just exited Veterans Day. We're looking forward to other future events and activities as we go into the winter."Asked about how restrictions will be enforced -- in light of Southern California sheriffs stating they won't be actively cracking down on health- order violations -- Ferrer said the county isn't relying on law enforcement, but rather hoping residents will take the urgency to heart."We really appreciate that the best enforcement is voluntary compliance," she said. "We've all done really well when we've set for ourselves a goal as a community and gotten behind it. I can't think of anybody at this point who's going to argue with the fact that we need to take some action to slow the spread, because this level of acceleration threatens our health care system."And that threatens care for every single person in this county -- for people who have a heart attack, for people who need emergency surgery, for people who need scheduled surgery, for people who are victims of car accidents or trauma."Ferrer also noted that the surge in cases is not just the result of increased testing. She said the county's rising rate of positive tests shows that the virus is spreading more rapidly. The county's seven-day average daily positivity rate among those tested for the virus was 3.9% on Nov. 1, but it rose to 5.1% by Nov. 8 and stood at 7.1%. as of Saturday. 5645

LOS ANGELES (AP) -- California fitness centers have filed a lawsuit alleging Gov. Gavin Newsom's measures aimed at curbing the spread of the coronavirus unfairly target the industry and are demanding they be allowed to reopen.Scott Street, a lawyer for the California Fitness Alliance, said Tuesday that the suit was filed in Los Angeles County Superior Court. It accuses state and Los Angeles County officials of requiring gyms to close without providing evidence that they contribute to virus outbreaks and at a time when staying healthy is critical to residents.State and county officials declined to comment on the suit. 632

LOS ANGELES (AP) — Californians mostly heeded warnings to stay away from beaches and other public spaces during the long weekend. State officials urged social distancing amid a spike in coronavirus infections and hospitalizations. Many communities canceled July 4 fireworks shows and other annual festivities — changes that appeared to successfully keep crowds at bay. However big waves at Southern California beaches proved irresistible to some surfers. California reported 6,500 additional confirmed cases of the virus on Saturday. The actual number of infections is thought to be far higher because many people have not been tested, and studies suggest people can be infected with the virus without feeling sick. 723
