WASHINGTON (AP) — For much of the United States, invasive grass species are making wildfires more frequent, especially in fire-prone California, a new study finds.Twelve non-native species act as "little arsonist grasses," said study co-author Bethany Bradley, a University of Massachusetts professor of environmental conservation.Wherever the common Mediterranean grass invades, including California's southern desert, fires flare up three times more often. And cheatgrass , which covers about one-third of the Intermountain West, is a big-time fire promoter, Bradley said."I would not be surprised at all if invasive grasses are playing a role in the current fires but I don't think we can attribute to them directly," Bradley said.University of Utah fire expert Phil Dennison, who wasn't part of the study but says it makes sense, said, "In a lot of ways, California was ground zero for invasive grasses. Much of California's native perennial grassland was replaced by Mediterranean annual grasses over a century ago. This study doesn't look at invasive grasses in the areas that are burning in California, but invasive grasses are contributing to the fires there."Experts say the areas burning now in California are more shrubs and grasses than forests, despite what President Donald Trump tweeted over the weekend."This is a global problem," said University of Alberta fire expert Mike Flannigan, who wasn't part of the study but said it makes sense. "I think with climate change and human assistance we are moving to a grass world. One region they should have mentioned is Hawaii where wildfires are increasing in large part due to invasive grasses."Invasive species are spreading more because of climate change as warmer weather moves into new areas, said study lead author Emily Fusco, also of the University of Massachusetts. New England and the Mid-Atlantic are seeing new invasive and more flammable grasses, Bradley said.The study in Monday's journal Proceedings of the National Academy of Sciences looks at the connections between a dozen species of invasive grasses and fires nationwide, finding fires occur more often in places with the non-native grasses. But the study did not find a link between invasive grasses and the size of the fires.Four of these species, including cheatgrass and common Mediterranean grass, are in California. These grasses get dry and then watch out, Fusco said."When you start a fire normally you want kindling," Fusco said. "The grasses are, more or less, like kindling"If someone lights a match and throws in the middle of a forest, it is unlikely a fire will start, but throw it in a field of cheatgrass "and odds are that it's going to catch," Bradley said."We are the reason that invasive species are here. We are the reason that they get spread around," Bradley said.Flanagan noted that invasive plants that are not grasses also feed the wildfire problem.While most outside experts said the study was important, wildfire expert LeRoy Westerling at the University of California, Merced said that with wildfires the size is key so this study is less valuable because it measures frequency.While size matters in forest fires, study author Bradley said mid to small size fires are the ones "in everybody's backyard" and affect people and their buildings more. 3313

WASHINGTON (AP) — A statue of Confederate Gen. Robert E. Lee that represented Virginia in the U.S. Capitol has been removed.Virginia Gov. Ralph Northam said in a statement that workers removed the statue from the National Statuary Hall Collection early Monday.“The Confederacy is a symbol of Virginia’s racist and divisive history, and it is past time we tell our story with images of perseverance, diversity, and inclusion,” said Northam.Each state is entitled to display two statues in the collection. Lee’s statue had stood with George Washington’s statue since 1909 as Virginia’s representatives in the Capitol.The Lee statue had been one among 13 located in the Crypt of the Capitol, representing the 13 original colonies.Northam had requested its removal and a state commission has recommended replacing Lee’s statue with a likeness of Barbara Johns.Johns was an American civil rights leader who protested poor conditions at her all-Black high school in the town of Farmville in 1951. Her court case became part of a landmark U.S. Supreme Court decision that struck down racial segregation in public schools.Virginia’s General Assembly must approve the replacement before a sculptor can be commissioned for the new statue. If approved, Johns would stand alongside Washington, and would be the only teenager represented in the collection.“I look forward to seeing a trailblazing young woman of color represent Virginia in the U.S. Capitol, where visitors will learn about Barbara Johns’ contributions to America and be empowered to create positive change in their communities just like she did,” said the governor.U.S. Sen. Tim Kaine of Virginia tweeted out a video of the Lee statue being taken down. 4:02 am. 12/21/20. Crypt of the US Capitol. pic.twitter.com/2ttGecsj5B— Tim Kaine (@timkaine) December 21, 2020 1827

VISTA, Calif. (KGTV) - A Vista family is crediting their 3-year-old French Bulldog with thwarting a burglar at the front door. Last Thursday, just past noon and eight minutes after Samantha Sanchez left her home on Olive Drive, she got an alert of noise near her door.When she got home, she saw her front door, busted and wide open."Felt violated. Disturbing," said Sanchez.A motion activated camera she had just installed to monitor her dog Harley - who suffers from epilepsy and is prone to frequent seizures - had captured part of what happened. On the video, the sounds of something being jammed into the door can be heard. Harley then starts to growl. The video stops and then skips 12 seconds. In the next images, Harley is seen sitting, staring at an open door. Sanchez believes the intruder never got inside because of her 30 lb. Frenchie."Thank God for Harley," said Sanchez.When it comes to Frenchies, there are snorter and non-snorters. Harley is definitely the former."You can see how he would be mistaken for a bigger, more aggressive dog just by how loud he is," said Sanchez.Sanchez cant help but smile when she thinks about what greeted the burglar at the door."Harley is my hero. He saved us," said Sanchez.His actions unfolded even though he may have needed the saving. A fresh urine stain that day meant he likely had a seizure during or after the break-in. But this hero wouldn't be stopped. "Harley got a new bed. Harley got a new toy and sausages. Harley gets whatever he wants now," said Sanchez.Sanchez says Harley will remain on alert. There have been two other burglaries in the same neighborhood in the past week. 1650

  

VISTA, Calif. (KGTV) – A group of teenage girls attempted to set a trap for a 32-year-old man who tried to meet one of them for sex, according to San Diego County sheriff’s officials. According to sheriff’s officials, deputies responded to a reported kidnapping at 1385 East Vista Way in Vista around 2:30 p.m. Sunday. A group of juveniles told responding deputies they used a social media app to contact “an older man who was looking for underaged girls to have sex with. The group hoped to expose the male and turn over the information to law enforcement agencies for prosecution.” Sheriff’s officials said the group made contact with Robert Dreyfus on the app and exchanged text messages. A meeting location was established at a shopping center at 1385 East Vista Way. Officials said that “Dreyfus arrived and convinced the 17-year-old victim to get into his vehicle to talk,” but he then drove away with the girl without consent. According to officials, the girl was able to message her friends for help, and they contacted authorities. Deputies made contact with Dreyfus, and he stopped his vehicle near the 2000 block of East Vista Way. The girl got out of his vehicle and was not hurt, officials said. Dreyfus was arrested by responding deputies and booked into Vista jail on suspicion of kidnapping, sending harmful matter to a minor and communication with a minor for specific offenses. Online, hundreds of groups that set up stings, hoping to expose child predators. “This was really dangerous and something that’s best left to professionals in law enforcement,” said criminal defense attorney Jan Ronis. Ronis said the teens’ actions could complicate the criminal case. “Normally, law enforcement runs these operations. The solicitation is recorded. The coversations, the meeting places are surveilled. This is a bunch of kids.” Dreyfus’ bail was set at 5,000, according to the San Diego County Sheriff's Department's inmate information. He’s due to appear in court next week. 1998

  

WASHINGTON — Control of the Senate won’t be decided until the new year after Republicans won a seat in Alaska.Neither party is able to lock the majority until January Senate runoffs in Georgia. Republicans added to their ranks Wednesday when Alaska GOP Sen. Dan Sullivan defeated Al Gross, an independent running as a Democrat. Sullivan's win means the Republican caucus are guaranteed 50 of the 100 seats in the Senate chamber. As of Wednesday, Democrats only controlled 48 seats.With Democratic President-elect Joe Biden’s victory, Republicans are still short of the 51 seats they need for majority control. That's because the vice president of the party in power, which on Jan. 20 will be Kamala Harris, is the Senate tie-breaker on votes. That means if Republicans only have 50 seats, Democrats can control the Senate.Control of the Senate will come down to a pair of run-off elections in Georgia, which will be held on Jan. 5. In a regularly-scheduled race, Republican Sen. David Perdue, currently seeking re-election for the first time, nearly missed out on the 50% needed in order to avoid a runoff. With 49.7% of the vote, he'll need to fend off Democrat Jon Ossoff to serve a second term.The second race is a special election to replace Republican Sen. Johnny Isakson, who retired due to health problems in 2019. Kelly Loeffler, who Gov. Brian Kemp tapped as Isakson's temporary replacement upon his retirement, will square off with Rev. Raphael Warnock. 1472
