Topline:
Cal State biologists and the group Orange County Coastkeeper are working together to use oyster shells from local restaurants to restore the once-abundant oyster beds along the coast and, by doing that, protect the shoreline from erosion and rising seas.
How does that work? Local restaurants donate discarded oyster shells. Those shells cure in the sun to remove pathogens, then hang off of docks in Huntington Harbour and elsewhere to provide a landing pad for oyster larvae floating through the water.
Once seeded with baby oysters, those shells are used in living shoreline projects designed to buffer the coastline.
Why oysters? When oyster larvae settle on shells, they start to secrete their own shell, effectively gluing the shells together to form oyster beds that encourage sedimentation and dampen the eroding force of waves. Oysters also filter the water, removing excess nutrients that cause harmful algal blooms.
It’s well before the lunch hour when a worker lugs a large plastic storage bin out of the kitchen at the Bluewater Grill in Newport Beach and into the back of Kaysha Kenney’s minivan.
The bin is full of discarded oyster shells from the previous night’s dinner service, plus some lemons and half-eaten bread. Kenney wants the shells, but the extra food bits are OK, she said, “because they sit out in a field and they have little animals that will come and kind of pick off the food scraps.”
This pickup is the first phase of a project led by Kenney’s group Orange County Coastkeeper. The goal is to use oyster shells from local restaurants to restore the once-abundant oyster beds along the coast and buffer the shoreline from erosion and rising seas.
Though the shells Kenney collects are non-native oysters, Coastkeeper’s project is focused on restoring Olympia oysters — the only native species along the West Coast. The species has been decimated by coastal development and overharvesting, starting in the Gold Rush days when they fed tens of thousands of hungry fortune-seekers.
In early fall, Orange County Coastkeeper collected dozens of oyster shell strings hanging off docks in Huntington Harbour. This year, they recruited more than 700 baby oysters or "spat" that will be transplanted to coastal restoration projects.

Stop 2: San Joaquin Marsh
With the blue Coastkeeper minivan full of stinky shells, Kenney heads inland to a hot, sunny patch of land next to the San Joaquin Marsh in Irvine. Here, she weighs each restaurant’s contribution, and spreads the shells out to cure in the sun to rid them of pathogens — and any leftover horseradish and tabasco sauce.
California regulations require the shells to cure for at least six months before they can be put back into the water. These particular shells are destined for the Seal Beach National Wildlife Refuge. Coastkeeper is working with California State University, Fullerton, and the U.S. Navy to build what’s called a living shoreline to help protect Navy buildings in the refuge that are threatened by erosion.
”A living shoreline is where we take an eroding shoreline and we effectively replant it with living plants and animals that can stabilize that shoreline,” explained Danielle Zacherl, a biology professor at Cal State Fullerton who’s leading the project.
And using discarded shells helps reduce restaurant waste.
“Think about this natural product that's getting sent to landfills that really could be doing so much more good,” Zacherl said.

Living shorelines are becoming popular across the country. They’re seen as more cost-efficient and ecologically friendly compared to what’s known as hard armoring, like seawalls and riprap. Zacherl and Coastkeeper have teamed up on several living shoreline projects along the Southern California coast, including in Newport Bay and Long Beach’s Alamitos Bay.
Oyster beds anchor the shoreline, keeping it from washing away, Zacherl explained.
“They also encourage sedimentation by generating eddies. The shells popping up into the water column slow the water velocity and allow sediment to filter down,” she said. “That's really important for coastal habitats right now, especially in the face of climate change.”

Oysters also filter the water, removing excess nutrients that cause harmful algal blooms. In fact, a single adult oyster can filter up to 50 gallons a day. They also improve water quality for eelgrass — which sequesters carbon, provides habitat for ocean critters and also helps prevent erosion.
The living shoreline planned for the Seal Beach refuge will be made up of a combination of oyster beds, eelgrass and another coastal plant, cordgrass. But first, Zacherl needs live oysters.
That’s where folks like Craig Schauppner come in.

Stop 3: Huntington Harbour
Schauppner is one of close to 90 residents in Huntington Harbour, at the northwestern end of Huntington Beach, who has become a kind of oyster nanny. Last spring, Coastkeeper gave him and the other volunteers strings of discarded and cured oyster shells to hang off their docks.
Oyster larvae floating through the water settle on those shells and start to secrete their own shell. Combined with other oysters, they effectively glue themselves together to form oyster beds.
During a visit last month, Schauppner pulled up a wire strung with more than a dozen oyster shells and pointed out a small dark circle on the inside of one of them.
“ So you could see, like right there, there's a spot. There might've been an oyster there at one time, but maybe a predator came and ate it or something like that,” he said.
His shell strings weren’t particularly attractive to baby oysters this year. But that’s OK, he said.

“Part of the project is to figure out where we can harvest oysters, where they can grow and, you know, where to avoid,” he said. “So I’m contributing to the data, right?”
At the end of September, Coastkeeper retrieved the shell strings from Schauppner and other volunteers in Huntington Harbour. They harvested more than 700 baby oysters, called “spat,” which were then transplanted to Seal Beach National Wildlife Refuge for the living shoreline project.
Kenney from Coastkeeper said it’s sometimes hard for the oyster nannies to let go but hopefully a little easier knowing their slimy charges will be helping clean the water and reestablish a resilient California coast.

Topline:
Mt. Baldy trails will reopen this weekend, including the Devil’s Backbone Trail, where three hikers were found dead in December. Officials closed parts of the San Gabriel Mountains to visitors after a series of winter storms made the trails unsafe.
Why were the trails closed? The U.S. Forest Service closed the popular trails on Feb. 10 because of icy terrain, heavy snow and other dangerous winter conditions, which made trail conditions unsafe. Last December, three hikers were found dead near the Devil’s Backbone Trail.
What will reopen: The National Forest System Trails that will reopen this weekend include:
Mt. Baldy Trail
Mt. Baldy Bowl Trail
Devils Backbone Trail
Three T’s Trail
Icehouse Canyon Trail
Chapman Trail
Ontario Peak Trail
Officials say: Outdoor recreation always involves inherent risk, especially in mountainous terrain during the spring and winter seasons, Keila Vizcarra, public affairs specialist for the Angeles National Forest, told LAist. “Anyone choosing to hike Mount Baldy, especially in winter, must stay vigilant about risks in that area,” Vuzcarra said in a statement.
What you need to know: Visitors are encouraged to check for updates and conditions online before visiting, or by calling the San Gabriel Mountains National Monument office at (626) 335-1251. There is no cell service throughout most of the Angeles National Forest and there are no gas stations in the forest.

Martial arts star Chuck Norris, who fought his way to fame in such 1980s action movies as TheDelta Force, Code of Silence, and a trilogy of Missing in Action films, has died. He was 86.
About his career: Norris karate chopped and kickboxed his way through more than a dozen action films in the '80s before leaping to TV, where he played Sergeant Cordell Walker, a decorated Vietnam veteran with Cherokee ancestry who championed the "Code of the Old West" in about 200 episodes of Walker, Texas Ranger.
Martial arts star Chuck Norris, who fought his way to fame in such 1980s action movies as TheDelta Force, Code of Silence, and a trilogy of Missing in Action films, has died. He was 86.
In a fight, Norris tended to lead with his right…foot.
He all but trademarked a roundhouse kick that villains never seemed to see coming. He'd plant a heel in someone's gut, spin once to knock him off balance with a boot to the chest, spin again to catch the guy's shoulder with his instep, maybe throw in a punch just to vary the rhythm, and finish him off with a high kick to the head.
It was art, and widely imitated, but it did not kick off his career at first. He was knocking around martial arts competitions and teaching celebrity clients in Hollywood, including Priscilla Presley, Bob Barker, and Donny and Marie Osmond, when his pal Bruce Lee gave him his break in films by inviting him to play one of many villains in 1972's The Way of the Dragon.
The film fetishized Norris' hairy chest opposite Lee's smooth one, and he gave a little smirk when he flattened Lee with a roundhouse kick early on. But it was Lee's film, and by scene's end, Norris was toast.
That could've been it, if one of Norris' celebrity students, Steve McQueen, hadn't suggested he take acting lessons. Norris did, and scored the leading role of a put-upon trucker in Breaker! Breaker!, an action flick shot in just 11 days.
It made money, and in a string of indie hits that followed, Norris established himself as America's first homegrown martial arts movie star. At which point, Hollywood studios came calling with bigger budgets, and titles like Forced Vengeance, Silent Rage, Lone Wolf McQuade, and Invasion U.S.A. In that one, Norris played a mercenary combatting a Soviet-led terrorist army that lands in Florida at Christmastime, taunting foes with lines like, "If you come back in here, I'm gonna hit you with so many rights, you're gonna beg for a left."
He karate chopped and kickboxed his way through more than a dozen action films in the '80s before leaping to TV, where he played Sergeant Cordell Walker, a decorated Vietnam veteran with Cherokee ancestry who championed the "Code of the Old West" in about 200 episodes of Walker, Texas Ranger.
Though a mostly non-verbal tough guy was his go-to role on screen, offscreen he established philanthropies for children and veterans, became a nationally-syndicated health and fitness columnist, got active in Republican politics, and wrote about 10 books including not just martial arts manuals, but two memoirs, two novels, and a conservative activist handbook called Black Belt Patriotism: How to Reawaken America.
At his home in Texas, he continued to work out and train well into his 80s. And though mostly retired in recent years, he was amused to find himself the subject of internet memes, "Chuck Norris Facts" that celebrated his supposed toughness with hyperbole and exaggeration.
"Did you know that I got bit by a king cobra?" he asks in one video, adding with a chuckle, "and after five days of agonizing pain, the cobra died."

The Trump administration announced Thursday a three-phase transition that will move significant management of and responsibility for the nation's federal student loan portfolio from the U.S. Education Department to the U.S. Treasury Department.
Why now: The administration says the Treasury Department is better equipped to, among other things, help millions of borrowers who are in default return to repayment on their loans, though the move is also political: The latest sign of President Trump's efforts to close the Education Department.
About the three-phase plan: The deal's first phase will see Treasury resuming control of collecting on defaulted student loans, an authority it has long held but deferred to the Education Department. The agreement's second phase expands Treasury's management beyond defaulted loans to include servicing much of what's left, even the Education Department's non-defaulted debts. The third and final phase would see Treasury take over key responsibilities beyond the handling of current loans, assuming administration of the Free Application for Federal Student Aid (FAFSA), which students are required to complete if they want to receive federal financial aid.
The Trump administration announced Thursday a three-phase transition that will move significant management of and responsibility for the nation's federal student loan portfolio from the U.S. Education Department to the U.S. Treasury Department.
The administration says the Treasury Department is better equipped to, among other things, help millions of borrowers who are in default return to repayment on their loans, though the move is also political: The latest sign of President Donald Trump's efforts to close the Education Department.
"As the Federal student aid portfolio soars to nearly $1.7 trillion and with nearly a quarter of student loan borrowers in default, Americans know that the Department of Education has failed to effectively manage and deliver these critical programs," said U.S. Secretary of Education Linda McMahon in a press release. "By leveraging Treasury's world-renowned expertise in finance and economic policy, we are confident that American students, borrowers and taxpayers will finally have functioning programs after decades of mismanagement."
More than 40 million borrowers hold federal student loans.
According to the interagency agreement obtained by NPR, the deal's first phase will see Treasury resuming control of collecting on defaulted student loans, an authority it has long held but deferred to the Education Department. A senior Education Department official told reporters that 9.2 million borrowers were in default as of the beginning of March, with another 2.4 million in late-stage delinquency on their payments.
The agreement's second phase expands Treasury's management beyond defaulted loans to include servicing much of what's left, even the Education Department's non-defaulted debts, "to the extent practicable, following Treasury's assessment of the portfolio and its operations."
The third and final phase would see Treasury take over key responsibilities beyond the handling of current loans, assuming administration of the Free Application for Federal Student Aid (FAFSA), which students are required to complete if they want to receive federal financial aid.
The Treasury Department already plays an important role in the FAFSA, using its data-retrieval tool to expedite the once-onerous income-verification process for families.
It was nearly one year ago that President Trump suggested a very different move – that the Small Business Administration (SBA) would assume responsibility for the student loan portfolio. It's unclear why the administration changed its thinking and pivoted to the Treasury Department.
This is the 10th interagency agreement the administration has reached to disperse large swaths of the work of the Education Department to other agencies.
"The Trump Administration continues to unlawfully dismantle the Education Department by moving programs and offices to other federal agencies despite clear warning from Congress that Education Secretary Linda McMahon lacks the authority to do so," said Rachel Gittleman, president of AFGE Local 252, which represents more than 2,000 current and former employees at the U.S. Department of Education.
In response to an NPR question, a senior Education Department official acknowledged that, as was the case with many of those previous agreements, the Treasury Department cannot fully assume all the Education Department's statutory student loan obligations. The official said the department will be wound down to the extent allowable by law and that Education Secretary Linda McMahon understands that "Congress is the only entity that can close the Department."
As for what impact this may have on borrowers, the department officials told reporters: "You should see no change. This should be seamless."
The Federal Communications Commission yesterday said it had approved the merger of local television giants Nexstar Media Group and rival Tegna, the same day that two lawsuits trying to block the deal were announced.
About the deal: Nexstar said last August that it would buy Tegna for $6.2 billion.
Where things stand: The deal needed the approval of the Republican Trump administration's FCC because the government had to waive rules that limit how many local stations that one company can own. Nexstar said it had also received approval from the Justice Department, but attempts to independently confirm that were not immediately successful Thursday.
Who opposes it: Attorneys general in eight states, including California, and DirecTV filed lawsuits with the U.S. District Court in Sacramento seeking to block the merger. The lawsuits make similar arguments that the deal will lead to higher prices for consumers and stifle local journalism.
The Federal Communications Commission on Thursday said it had approved the merger of local television giants Nexstar Media Group and rival Tegna, the same day that two lawsuits trying to block the deal were announced.
Nexstar said last August that it would buy Tegna for $6.2 billion. The deal would create a company that owns 265 television stations in 44 states and the District of Columbia, most of them local affiliates of ABC, CBS, Fox and NBC. FCC Chairman Brendan Carr said the company had agreed to divest itself of six of those stations.
The deal needed the approval of the Republican Trump administration's FCC because the government had to waive rules that limit how many local stations that one company can own. Nexstar said it had also received approval from the Justice Department, but attempts to independently confirm that were not immediately successful Thursday.
"We are grateful to President Trump, Chairman Carr and the DOJ for recognizing the dynamic forces shaping the media landscape and allowing this transaction to move forward," said Perry Sook, Nexstar's chairman and CEO.
Attorneys general in eight states and DirecTV filed lawsuits with the U.S. District Court in Sacramento, California, seeking to block the merger. The lawsuits make similar arguments that the deal will lead to higher prices for consumers and stifle local journalism.
The action was filed by the top lawyers in California, Colorado, Connecticut, Illinois, New York, North Carolina, Oregon and Virginia — all of them Democrats. "If this merger moves forward, cable prices will spike for consumers in New York and across the country," said Letitia James, New York attorney general, on Thursday. The state lawyers argued the merger would run afoul of federal laws designed to protect against monopolies.
Similarly, DirecTV predicted the deal would allow Nexstar to jack up the price it can extract from DirecTV and other distributors to carry their stations, "which will force them to raise prices to their subscribers."
Given Nexstar's tendency to consolidate newsrooms in communities where it owns more than one station, both lawsuits expressed concern that the merger would hurt the already struggling local news business. There are 31 markets across the country where Nexstar and Tegna own at least one station, according to the states' lawsuit.
In approving the deal, Carr said that "if you care about local news, you should care about the future of local broadcast stations." He said the deal will ensure that the broadcasters have the resources to continue investing in those operations. Sook, too, said Nexstar will be a stronger company, "better positioned to deliver exceptional journalism and local programming."
Nexstar had no direct comment on the lawsuits, a spokesman said.
The merger was endorsed in February by President Donald Trump, who wrote on social media that "we need more competition against THE ENEMY, the Fake News National TV Networks."
Anna Gomez, a Democratic member of the FCC, condemned the Republican-controlled agency's decision, saying it was done behind closed doors without an actual vote.
"Local journalism is under extraordinary strain," she said. "Across the country newsrooms are being consolidated, reporters laid off and editorial decisions made far from the communities broadcast stations are licensed to serve. The Nexstar-Tegna merger will accelerate exactly that trend, concentrating broadcast power in fewer corporate hands, shrinking independent editorial voices and prioritizing national business interests over local needs."
Nexstar flexed its muscles last fall in ordering its ABC stations to yank late-night host Jimmy Kimmel following comments he made about assassinated Republican activist Charlie Kirk, briefly leading to Kimmel's suspension. But ABC brought Kimmel back following an outcry, and Nexstar backed down.
The attorneys general said they were open to having other states support their actions — even those whose chief legal officials are Republicans.
