Officials declare 'urgent' threat as invasive species never before seen in North America is discovered: 'A serious challenge'
A tiny invasive species no bigger than a paper clip is causing concerns across Northern California's waterways. Golden mussels, never before seen in North America until October, have been discovered clinging to equipment in the Sacramento-San Joaquin Delta, reported SFGate.
These caramel-colored mollusks from China and Southeast Asia were likely introduced by international shipping vessels and have already spread to multiple California water bodies, including the San Luis Reservoir.
The California Department of Fish and Wildlife released a plan to stop these little invaders, calling them an "urgent invasive species threat."
"The discovery of golden mussels in California is a serious challenge that requires coordinated action and a long-term commitment," CDFW Director Charlton Bonham said in a news release, per SFGate.
Like invasive plants that outcompete native vegetation, these aquatic invaders disrupt the natural balance of our ecosystems. They form dense colonies that can clog pipes, damage boat motors, and disrupt drinking water infrastructure that two-thirds of California residents depend on.
The financial impact could be substantial. According to officials, removing these mussels requires "costly removal to maintain operational function" of water systems that serve millions of people.
This situation mirrors the challenges homeowners face when dealing with invasive plants in their yards. Native landscaping is a solution with several benefits for your wallet and the planet.
Native plants typically need less water than non-native options, helping you conserve water and lower your monthly bills. They also require less maintenance, saving you time and money on lawn care.
You can choose from options such as buffalo grass, which needs minimal watering once established, or try a clover lawn that stays green with little effort. Xeriscaping with drought-resistant plants works well in drier climates, while native wildflower gardens attract essential pollinators.
These pollinators help maintain our food supply, creating a healthier ecosystem that benefits everyone. Replacing even part of your lawn with natives can make a difference.
Should we be actively working to kill invasive species?
Absolutely
It depends on the species

If you're a boater, you can help protect California's waterways by following the "clean, drain, dry" rule for your watercraft between launches. This simple step prevents hitchhiking mussels from spreading to new locations.
If you spot any suspicious shells, you can report them by sending photos to the CDFW's invasive species program through its website or by calling its hotline at 866-440-9530.

Officials searching for large South American lizard in Santa Clara County park
The Brief A large Argentine black and white tegu was spotted by hikers in Joseph D. Grant County Park in Santa Clara County. Tegus tend to eat bird eggs, small birds, small lizards and various "small mammals and invertebrates." However, they are also docile and are generally not dangerous to humans. Anyone who spots the lizard is asked to contact staff onsite or to report the sighting to the park office at 408-274-6121. SANTA CLARA COUNTY, Calif. - Authorities on Friday were searching for a large Argentine black and white tegu that was spotted by hikers in Joseph D. Grant County Park. The Santa Clara County Parks and Recreation Department issued an alert Friday afternoon announcing that park personnel were on the lookout for the large reptile, which was spotted in the park in the past few days by a group of hikers. A what? Santa Clara County Parks said the Argentine black and white tegu – as the name might suggest – is not native to California. According to the Florida Fish and Wildlife Conservation Commission, the lizards are endemic to Brazil, Paraguay, eastern Uruguay and northern Argentina. Tegus tend to eat bird eggs, small birds, small lizards and various "small mammals and invertebrates," according to Santa Clara County Parks. However, they are also docile and are generally not dangerous to humans. "They're a popular pet and don't belong in parks," the department said in a statement. Officials are still on the lookout for the loose tegu, and anyone in Joseph D. Grant County Park who spots the lizard is asked to contact staff onsite or to report the sighting to the park office at 408-274-6121. The Source Santa Clara County Parks and Recreation Department

Sierra Madre search and rescue team faces financial difficulties following Eaton Fire
A local search and rescue team that helped evacuate people during the Eaton Fire now needs rescuing of its own. The Sierra Madre Search and Rescue team is dealing with unexpected costs from the fire. Rob Klusman, a healthcare consultant, is the team's operations leader. He has been with the organization for 29 years. "Most of our responses we have are all away from vehicles and up trails, so we have to walk to everything or fly," Klusman said. Lauren Capoccia, a San Bernardino nurse, also volunteers as one of 42 team members. The Sierra Madre Search and Rescue team has 42 members who help respond to fires at no cost in the steep terrain of the San Gabriel Mountains. KCAL News They have all put in hundreds of hours a year responding to calls for help at no cost in the steep, unforgiving terrain of the San Gabriel Mountains. When the Eaton Fire started the night of Jan. 7, they were called to help with evacuations. "We were up in the canyon evacuating houses, making sure people out aware of going on," Capoccia said. Helping residents evacuate came at a cost to the hardworking nonprofit that has a budget of about $80,000. They need pickets for anchors, replacement rescue ropes, replacement fire shelters and they need a new rescue truck. "This truck is 25 years old at this point," Klusman said. The rescue team has set up an online fundraising campaign and Klusman, like every team member, saves money where they can. "I used dental floss to sew up and close the holes," he said about his gloves. Members spend thousands of their own money to buy their gear. In their free time, they train in the mountains charred by the fire. With dead and burned trees after fire, they now have to haul up a 45-pound bag of metal pickets to conduct the rescue missions. "For the next 5-8 years, once they re-open this, we are prepared to use picks and tools," Klusman explained. "Can't rely on trees or natural anchors that used to be here." Even with the financial difficulties, the team remains determined to keep protecting the people in their foothill city, at whatever cost.

Folsom Zoo Sanctuary asks for public's help in naming its new bear
The Folsom Zoo Sanctuary has taken in a new bear, and the public can now help choose its name. Back in March, the Folsom Zoo welcomed a bear named Herbie after the closure of a different Northern California wildlife facility. Herbie was living with a female bear at the other facility, but for some reason the other handlers wanted the pair to go their separate ways. Circumstances changed, however, and the female bear has since joined Herbie at the Folsom Zoo. Don't miss your chance to help name the zoo sanctuary's newest resident! The new Eurasian Brown Bear is enjoying her... Posted by Friends of the Folsom Zoo Inc on Tuesday, June 3, 2025 Now, the zoo is asking for the public's help in choosing the female bear's name. For a minimum donation of $5, people can vote for either Matilda, Petunia or Magnolia as the bear's name. The Folsom Zoo Sanctuary is home to dozens of animals. The zoo's summer hours run Thursday through Sunday, 9 a.m. to 3 p.m.
