Survey of nature’s superhero, eelgrass, kicks off Carlsbad bridge project
Two researchers in an inflatable boat glided out onto Batiquitos Lagoon in Carlsbad Thursday morning looking for eelgrass, an underwater plant that provides a nursery for fish, crabs, shrimp and other sealife.
The boaters, equipped with sonar and diving gear, also were looking for any sign of Caulerpa, an invasive seaweed that can spread rapidly and choke out the native eelgrass. Nicknamed “killer algae,” Caulerpa taxifolia turned up in Carlsbad’s nearby Agua Hedionda Lagoon in 2000 and was eliminated only after an intensive, multi-year, $7 million battle.
Since then, the invader, which may have been dumped from a home aquarium, has been absent along the North County coastline. However, last year, small amounts of a slightly different but equally destructive species, Caulerpa prolifica, were found in San Diego Bay and efforts are underway to eradicate it.
The one-day Carlsbad survey are part of the preparations for replacing the 80-year-old wooden railroad trestle that crosses the lagoon. Construction is expected to begin this fall and be completed in 2028 at a cost of about $165 million. State law requires construction to pause from April 15 to July 31 each year during the California least tern nesting season.
A survey in 2015 showed several dense beds of eelgrass spread between a few sparse areas in the lagoon, said Derek Langsford, an environmental compliance consultant working with the San Diego Association of Governments.
Eelgrass is considered one of nature’s superheroes. One of many species of seagrasses, its long, slippery blades offer shade and camouflage for young fish. Eelgrass anchors shorelines and provides food and habitat for a variety of marine life.
Growth of the perennial plant varies from year to year depending on the weather, rainfall and other factors.
“We’ve had two relatively wet winters,” Langsford said. “That brings more freshwater flowing through the channel of the lagoon. Eelgrass does not like freshwater.”
Storm runoff also brings silt and sediment, which cloud the water and prevent light from reaching the plant for the photosynthesis it needs to survive.
“These lagoons are very sensitive, and they support a bunch of endangered species,” said Sue Scatolini, a biologist at the California Department of Transportation, or CalTrans. “Salt marsh and lagoon habitats are very important.”
More than 200 species of birds have been seen at the lagoon, including the endangered California least tern and the western snowy plover. The shallow water is a breeding ground for biologically and commercially important ocean fish such as halibut and sculpin.

Other than eelgrass, there’s not a lot of vegetation in the lagoon, Scatoline said. Most of the bottom is shallow and sandy, much of it only knee deep at low tide. The deepest part is the channel under the bridge, where the bottom is scoured by the current.
Eelgrass is a flowering underwater plant, not seaweed, that grows in areas from the tidal zone down to about 20 feet deep.
Native Americans collected it for food, roofing, basket weaving, smoking deer meat and as a cure for diarrhea. Early California settlers used it to thatch their roofs, as well as for fuel, bedding and a soil conditioner.
Industries have used eelgrass to make paper, cigars, upholstery and packing materials. However, today state law prohibits its commercial or recreational harvest, according to the state Department of Fish and Wildlife.
SANDAG, which oversees the bridge replacement project, will be required to replace any eelgrass that the survey finds growing in the area affected by construction. Should any Caulerpa be discovered, construction could be delayed until the invasive plant is removed.
“We don’t think we will encounter any Caulerpa here,” said Tim Pesce, a senior environmental planner for SANDAG.
The old, single-track railroad bridge is being replaced with a double-track concrete bridge that brings numerous environmental and operational benefits.
The new bridge will be longer with less of a footprint in the water, which will improve tidal flows and water quality in the lagoon. Instead of standing on more than 100 closely spaced wooden posts or piers in the water, the new structure will be supported by concrete piers set 56 feet apart.
Another benefit will be the excavation of about 40,000 cubic yards of sand, Pesce said. The sand will be used to replenish nearby South Ponto Beach and to expand an eroding least tern nesting area near the mouth of the lagoon.
As for operational benefits, a second set of tracks improves the speed and efficiency of service by allowing trains to pass each other.
So far SANDAG has double-tracked about three quarters of the 60-mile corridor from downtown San Diego to the Orange County border. The Batiquitos bridge project will add more than half a mile of double-track, eliminating a bottleneck between Carlsbad and Encinitas.
The bridge project strengthens an important link in the 351-mile Los Angeles-San Diego-San Luis Obispo, or LOSSAN, rail corridor.
The LOSSAN corridor is San Diego County’s only passenger and freight train connection with Los Angeles and the rest of the United States. It’s also part of the federal Strategic Rail Corridor Network connecting military bases across the country.
Locally, the corridor is used daily by North County Transit District’s Coaster commuter trains, Amtrak passenger service, and BNSF Freight.
Amtrak’s Pacific Surfliner makes 13 daily round-trips between San Diego and Los Angles. The Coaster makes 15 daily round-trips between Oceanside and San Diego on Mondays through Thursdays, 16 on Fridays, 11 on Saturdays and nine on Sundays.

New UC San Diego club looks to promote Chinese culture and bring people together
A new club at UC San Diego in La Jolla is rooted in Chinese art, language and food, but its primary focus is on bridging the gaps among different cultures.
When second-year UCSD student Lydia Xie moved from Singapore to San Diego, she began to notice a general lack of understanding about Chinese culture, she said. Her interest grew as she read a social media thread of UCSD students discussing international students’ tendency to socialize with people from the same background.
Looking to foster cross-cultural sharing and understanding, Xie decided to form a new campus club, Lotus Bridge @ UC San Diego.
“We do have some Chinese student organizations on campus, but based on my understanding, they’re usually focused on having Chinese international students in those groups,” Xie said.
“[There’s] nothing wrong with that,” she added. “I think that is great for them to be finding community here in a foreign country. But for me … I would love to have a platform where we can share Chinese culture to other people who might not be as familiar with it.”
Lotus Bridge aims to unite diverse cultures, hold activities such as dessert-making and foster teamwork and leadership, Xie said. The group registered as a student organization in September, followed by a promotional push on social media starting Jan. 7 and its first general meeting Jan. 22.
Xie is the group’s founder and president. Other founding members are UCSD students Helena Ren, Qianqian Yang, Anny Ma and Chloe Zhang.
Yang, a fourth-year visual arts student, said she got acquainted with the group through a social media post.
“It kind of just popped up,” she recalled. “I never saw this before on campus, so I really wanted to join.”
Ma said the club offered a meaningful way of getting connected with the university in her freshman year as a sociology student.
Ahead of its first meeting, the club set up a table by the university’s Geisel Library to quiz fellow students on Chinese culture, such as when the Mid-Autumn Festival takes place (this year it’s Sept. 25) and how many tones are in the Mandarin language (four).
People who registered for the meeting were asked to fill out a form, with one of the prompts asking them about their level of familiarity with Chinese culture. On a scale of 1-10, most respondents scored themselves between three and seven, Xie said.
At the event, guests baked Chinese peach blossom pastries at Marshall College’s Umoja Community Kitchen. The pastries are a popular dish year-round, including during the Mid-Autumn Festival.
“[By] learning to make traditional pastries, we can understand the festival and the folk tales behind them,” Ma said. “We hope through baking, we can promote cross-cultural communication and enable people from different backgrounds to experience Chinese culture.”
Xie said she hopes the introductory event and others to follow will create unity among UCSD students.
“I think success for this club is just about boosting people’s understanding of Chinese culture,” she said. “I really want to build a community where everybody can be more empathetic and more understanding of people from different backgrounds.”
According to the Center for Student Involvement, UCSD is home to 692 student organizations for the 2025-26 academic year. See a full list at studentorg.ucsd.edu.

San Diego County Gun Owners PAC gives reaction to latest shooting death by ICE
The San Diego County Gun Owners PAC (Political Action Committee) calls the fatal shooting of Minnesota man Alex Pretti by ICE agents “tragic and deeply troubling.”
The executive director of that organization, Michael Schwartz, told NBC 7 he’s calling for full transparency and due process moving forward.
“Both sides, Mr. Pretti and whoever the border agent was involved in the shooting, deserve a thorough investigation,” Schwartz said.
Schwartz says gun owners are loyal to principles, not parties, and believes it’s important to not turn Alex Pretti’s death into a political narrative.
“The Second Amendment has never been a Republican, Democratic or Libertarian or Green or any party issues, it’s nonpartisan. When people no matter their party do something to support the Second Amendment, we sing their praises and when they do something against it, we harshly condemn them. You saw that in this case, you saw Gun Owners of America and the National Rifle Association quickly come out with statements that were bashing certain Trump Administration officials and saying, hey we need to investigate this shooting,” Schwartz said.
On Tuesday, when talking about the most recent deadly ICE shooting in Minnesota, President Donald Trump said, “You can’t have guns. You can’t walk in with guns.”
Schwartz disagrees with what the Trump Administration has recently said about those legally carrying a firearm.
“I am completely opposed to some of the statements by Trump employees, like Kash Patel and others, who implied that somehow being a concealed carry permit holder somehow makes you more dangerous to law enforcement or implies that you’re a criminal,” Schwartz said.
According to Johns Hopkins Center for Gun Violence Solutions, strict regulating of public carry laws are associated with lower rates of firearm crimes. Schwartz believes the rise of physical interactions between citizens and ICE might provide an opportunity.
“I think law enforcement needs to be better educated on who a concealed carry permit holder is. The fact that they go through a background check and training and the fact that as a group they tend to commit fewer crimes than the general public. Educating on who they are and what their motivation is is important to all levels of law enforcement,” Schwartz said.
Schwartz says gun rights advocates have been concerned with government overreach for decades surrounding the Second Amendment and will be closely following how current events play out.
While California has some of the most restrictive gun carry laws in the nation, it’s interesting to note that San Diego County has gone from 11,000 carry permits to over 26,000 in last seven years.

Investigation underway after person shot, injured by Escondido police
An investigation is underway after one person was shot and injured by an Escondido Police officer early Tuesday.
Police were called to a transitional house on the 100 block of S Elm Street, on reports of a man who cut himself and was armed with a knife, San Diego Police Homicide Lt. Lou Maggi said.
Police tried to negotiate with the man, who then barricaded himself inside a bathroom. Officers then left to try to de-escalate the situation, Maggi said.
Police were called again after the man had left the bathroom and was roaming the outside of the property. A K-9 officer arrived to find the man in an alleyway with a “24-inch stick.” After multiple calls from the officer to drop the weapon, the man then charged at the officer, prompting the officer to shoot the man, Maggi said.
The man was shot multiple times and taken to a local hospital in critical condition. The Escondido officer involved in the shooting was not injured.
Neither the man nor the officer has been identified at this time.
The other residents at the transitional housing were safely evacuated.
The San Diego Police Department is investigating the incident per a memorandum of understanding that prevents law enforcement agencies from investigating use-of-force cases involving their own officers.
