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) — A homeless man is facing a murder charge in what authorities say was a random attack on a California father, who was stabbed in the neck as his 5-year-old daughter sat on his lap in a crowded beachside steakhouse.Jamal Jackson, 49, was charged with first-degree murder in the death of 35-year-old Anthony Mele. He was being held in Ventura County jail on a .5 million bail. It was unclear Saturday if he had an attorney to speak on his behalf.Mele and his wife were eating dinner with their daughter Wednesday at Aloha Steakhouse in Ventura. The girl was sitting on her father's lap when prosecutors say Jackson walked up and stabbed Mele in the neck.Prosecutor Richard Simon said patrons and a restaurant employee followed Jackson out of the restaurant, even though he still had the knife. They kept track of him until police arrived and arrested him.Mele was taken to a hospital and died Thursday after being taken off life support."It's horrible," Simon said. "You don't think you're going to be killed when you go out to dinner at a nice restaurant with your family and you didn't do anything."Simon said the two men had not interacted before the attack."He was just sitting there with his daughter in his lap," Simon said. "You're not supposed to die that way."Mele's loved ones started a GoFundMe page to help raise money for a funeral and to support his wife and daughter.Mele's Facebook page was filled with photos of his daughter and said he was a manager at an AT&T store.Police confirmed Saturday that a bystander reported a man who turned out to be Jackson for disruptive behavior several hours before the stabbing.According to the bystander, a man was yelling on the promenade not far from the restaurant about three hours before the attack.Patrol officers were out on other calls so command center staff monitored the man — who turned out to be Jackson — via a pier security camera system for more than 20 minutes before determining he didn't seem to be a threat, police said.Police are asking anyone who spoke with Jackson during that time to contact investigators.The killing prompted the Ventura City Council to increase police patrols in the area and add staff members to monitor security cameras, among other measures."We are extremely disheartened and infuriated by this criminal attack," Mayor Neal Andrews said in a statement. "We will not tolerate this in our community. Nothing is more important than the safety of our visitors, residents and businesses."If convicted, Jackson faces up to 55 years in prison. He has prior convictions for burglary and unlawful sexual intercourse dating back to the 1990s, according to online court records. 2696

LOS ANGELES (CNS) - An initiative to split California into three states has received enough signatures to qualify for the November ballot, its author said Wednesday.Venture capitalist Tim Draper said backers of what he has dubbed "CAL 3" would submit petitions with more than 600,000 signatures to election officials next week. The initiative needs signatures from 365,880 registered voters - five percent of the total votes cast for governor in the 2014 election - to qualify for the ballot."This is an unprecedented show of support on behalf of every corner of California to create three state governments that emphasize representation, responsiveness, reliability and regional identity," Draper said.   Splitting California into three states would require congressional approval. One proposed state would be called California or a name to be chosen by its residents after a split. It would consist of Los Angeles, Ventura, Santa Barbara, San Luis Obispo, Monterey and San Benito counties. A second state, Southern California or a name to be chosen by its residents, would consist of Orange, Riverside, San Bernardino, San Diego, Imperial, Kern, Kings, Fresno, Tulare, Inyo, Madera and Mono counties.   The remaining 40 counties would be part of the state of Northern California or a name chosen by its residents.   Draper said he conceived the initiative out of a belief that "the citizens of the whole state would be better served by three smaller state governments while preserving the historical boundaries of the various counties, cities and towns."   Steven Maviglio, a longtime Democratic Party political consultant who was a co-chair of the effort to oppose Draper's 2014 initiative to split California into six states, told City News Service, "Splitting California into three and creating three new governments does nothing to solve our state's challenges other than tripling them." "CAL 3'' has no connection to efforts to have California succeed from the United States. 2050

  

LOS ANGELES (AP) — Federal investigators who examined the burned-out wreckage of a scuba diving boat have not been able to determine what ignited a fire that killed 34 people off the California coast, a law enforcement official said Friday.Teams from the FBI and Bureau of Alcohol, Tobacco, Firearms and Explosives left after spending two weeks reviewing what remains of the Conception, according to an official with knowledge of the investigation.Parts of the vessel have been sent to labs for additional testing, said the official, who was not authorized to release the information publicly and spoke on the condition of anonymity. There is no indication anyone intentionally set the Sept. 2 fire.Six crew members were asleep when the fire broke out before dawn and trapped those sleeping in bunks below deck. Coast Guard rules require a roving watchman, and authorities were looking into possible criminal charges that would likely focus on an obscure federal law known as the seaman's manslaughter statute.RELATED: San Diego woman killed in deadly Conception boat fire off Santa BarbaraWith the boat propped up by braces and scaffolding, investigators wearing protective suits walked over planks to inspect and document the burned vessel at Port Hueneme, a naval base more than 60 miles (97 kilometers) northwest of Los Angeles, the official said. Some parts of the boat washed away because it was submerged for two weeks off Santa Cruz Island.Authorities also will examine hundreds of documents seized from the boat's owner, Truth Aquatics Inc., days after the fire.The Coast Guard, FBI and U.S. attorney's office in Los Angeles are leading a criminal investigation into the blaze, and the National Transportation Safety Board is conducting a safety inquiry.The captain and four crew members asleep on the vessel's upper deck survived the fire. The sixth, a 26-year-old deckhand named Allie Kurtz, was sleeping below deck and perished with the boat's 33 passengers.Truth Aquatics preemptively filed a federal lawsuit under a pre-Civil War maritime law that shields boat owners from monetary damages in a disaster at sea.Ryan Sims, a cook on the boat who broke his leg trying to escape the flames, claimed in a separate lawsuit that the boat was unseaworthy and operated in an unsafe manner.Coast Guard records show the Conception passed its two most recent inspections with no safety violations. 2408
