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) — Authorities say an off-duty Los Angeles County deputy was shot early Sunday morning while he was driving and returned fire at the suspect. The sheriff's deputy's name has not been released. Officials say Sunday he was struck once in a lower extremity and is expected to survive his injuries. Authorities say the suspect remains at large and it’s not known if he was struck by gunfire before he ran away. The other two people in the deputy’s vehicle were not hurt. Additional information, such as if the deputy knew the gunman, was not immediately available. 584

LOS ANGELES (AP) — The two Southern California desert communities rocked by last week's powerful earthquakes may have sustained as little damage as they did because they have no tall buildings and many of the homes in one are fairly new and were built to stricter earthquake standards.California's Seismic Safety Commission Chairman Michael Gardner said during the agency's Thursday meeting that the tallest building he knows of in the Mojave Desert towns of Ridgecrest and Trona is the three-story Ridgecrest hospital.The region was struck by a magnitude 6.4 earthquake on July 4, followed by a 7.1 temblor the next day.Ridgecrest, whose 28,000 residents include many who work at the nearby China Lake Naval Weapons Center, is about 150 miles (241.4 kilometers) east of Los Angeles.The nearby mining town of Trona, with a population of about 2,000, was harder hit. Commissioners noted many of its buildings are older.Authorities estimated the damage to both towns at about 0 million, although that could go up as buildings continue to be evaluated.Commissioner Kit Miyamoto said that as inspectors entered some buildings they discovered serious damage to ceilings and other areas that they couldn't see from the outside."Three buildings from the exterior appeared to be fine and probably safe for entry, but upon further investigation the roofs had actually collapsed," he said, adding inspectors may find others in that condition.Gardner said commissioners are also waiting for more information from the Naval base, where security is tight.Miyamoto noted that many of Ridgecrest's homes were built in the 1980s and '90s of more earthquake-resistant materials."As we know, newer California houses hold up really well," he said.That was not so much the case in Trona, where many fireplace chimneys collapsed and other damage was recorded.Buildings flooded when water heaters toppled over and ruptured gas lines sparked fires, and roads, highways and sidewalks also buckled.Trona also lost all of its water for several days when a pipeline carrying it from Ridgecrest ruptured. It was restored Thursday, but San Bernardino County spokesman David Wert said a "boil order" remains in place while water lines are being flushed. Meanwhile, free water was being distributed to residents.Other utilities to both towns have been restored, and Gardner said a local assistance center opened in Ridgecrest on Thursday.The commission itself plans to meet in Ridgecrest next month.No one in the area was killed, although authorities believe the quake may have taken the life of a man in the small Nevada town of Pahrump, 180 miles (289.7 kilometers) away.Troy Ray, 55, of Pahrump was killed when his jack slipped as he was working underneath his car. The shaking from one of the quakes felt from Las Vegas to Los Angeles might have caused the jack to slip, although authorities noted they couldn't be sure.Separately Thursday, California Insurance Commissioner Ricardo Lara and California Earthquake Authority CEO Glenn Pomeroy urged residents statewide to consider buying earthquake insurance that they said could be tailored to meet homeowners' and renters' individual needs and pocketbooks.Contrary to some reports, they said the insurance is available everywhere in California. But new policies won't cover damage resulting from aftershocks related to the series of quakes that began July 4 until 15 days have elapsed.___Associated Press Writer Don Thompson in Sacramento contributed to this story. 3500

LONDON (AP) — Britain, the United States and Canada are accusing Russia of trying to steal information from researchers seeking a COVID-19 vaccine.The three nations alleged Thursday that hacking group APT29, also known as Cozy Bear and believed to be part of the Russian intelligence service, is attacking academic and pharmaceutical coronavirus research institutions involved in vaccine development.They say the persistent and ongoing attacks are seen as an effort to steal intellectual property, rather than to disrupt research.Britain’s National Cybersecurity Centre made the announcement, coordinated with authorities in the U.S. and Canada.The NCSC says APT29 uses a variety of tools and techniques to predominantly target governmental, diplomatic, think-tank, healthcare and energy targets for intelligence gain.“Throughout 2020, APT29 has targeted various organizations involved in COVID-19 vaccine development in Canada, the United States and the United Kingdom, highly likely with the intention of stealing information and intellectual property relating to the development and testing of COVID-19 vaccines,” wrote the NCSC.It’s also unclear whether Russian President Vladimir Putin knew about the vaccine hacking, but officials believe such intelligence would be highly prized. 1294

LOS ANGELES (AP) — Orange County sheriff's deputies shot and killed a Black man Wednesday after he allegedly tried to grab one of their guns during a struggle. According to an Orange County Sheriff's Department press release, two deputies from the Homeless Outreach Team made contact with the man outside the Hotel Miramar in San Clemente. "During the contact, a physical altercation occurred. Surveillance video at the scene showed that during the physical altercation, the subject attempted to gain control of a deputy’s gun," the department said in the news release. "Shortly after, a deputy-involved shooting occurred. Deputies began lifesaving measures, and the subject was pronounced deceased at the scene."The latest killing of a Black person by law enforcement happened on the same day as the decision not to charge Kentucky police officers for Breonna Taylor's death was announced. Part of the incident Wednesday afternoon in San Clemente, California, was captured on video and posted to social media by the Southern Orange County Black Lives Matter group. The man's name has not been released by authorities. It's not clear from the video if the man tried to grab the firearm. 1194
