Representative Josh Harder (CA-10) announced legislation to eradicate and control the population growth of nutrias, colloquially referred to as “swamp rats,” in the Central Valley. Nutrias are an invasive species from South America that have caused millions in damage to swamplands in Maryland and Louisiana. They have been detected in large numbers in the Central Valley and rapidly reproduce. The bill is cosponsored by fellow Central Valley representatives Jim Costa, John Garamendi, and TJ Cox.

“It sounds ridiculous, but these swamp rats are actually a major problem for our water infrastructure. They can cause floods by destroying irrigation canals and levees – that’s the last thing farmers and homeowners need right now. They’re also a serious threat to our wetlands and local ecosystems,” said Rep. Harder. “My bill would revive a program that helped successfully get rid of the pests in Maryland and bring millions of dollars in federal help to the Central Valley.”

“Nutria continues to be a problem in my district and most of the San Joaquin Valley, making life more difficult for farmers,” said Rep. Costa. “California has taken steps to help control the issue, but we must keep pushing for federal funding to eradicate this pest once and for all.”

“These invasive rodents are incredibly destabilizing for the local levees and flood control infrastructure that keeps our communities safe. Sacramento and the Central Valley are already flood prone regions, and we must do everything in our power to ensure nutria don’t exacerbate that risk. We already know there’s a program with a proven track record of eradicating these pests, and our legislation would bring that program to the region and rid our communities of these rodents at a minimal cost,” said Rep. Garamendi.

“The California Department of Fish and Wildlife needs help to control and eliminate this invasive pest, so I'm pleased to join my colleagues in boosting efforts to protect our native wildlife, threatened wetlands, and waterways,” said Rep. Cox.

Rep. Harder’s bill would reauthorize the Nutria Eradication and Control Act of 2003, which was considered successful in the Chesapeake Bay, and direct $7 million in funding towards management of the species in California. The programs supported by the bill encourage habitat protection, education, research, monitoring, and capacity building to provide for the long-term protection of wetlands from destruction caused by nutrias.

Nutrias were originally introduced to the United States as part of the fur trade in the late 1800s but were eradicated from California in the 1970s. The species was rediscovered in the Central Valley in 2017. There have been 531 nutrias removed from the Central Valley since this first sighting. They can devour up to 25 percent of their body weight daily and have up to 200 offspring per year.

Suspected observations or potential signs of nutria should be photographed and immediately reported to CDFW’s Invasive Species Program by e-mail to invasives@wildlife.ca.gov, or by phone at (866) 440-9530.

Costa, Gray propose congressional bill to address critical physician shortage in rural areas

Two San Joaquin Valley congressional representatives have introduced a bill that could help address the vast shortage of doctors in the region, particularly in underserved areas. 

Rep. Jim Costa, D-Fresno, and Rep. Adam Gray, D-Merced, say the Medical Education Act would, if passed, establish a program of grants to support expanded medical education programs in underserved areas of the nation.

The Valley could be one of the key areas that would benefit from the legislation. California has about 90 primary care doctors per 100,000 residents statewide, the federal Health Resources & Services Administration reported in November 2024. 

That’s more than the ratio in some states, and less than some others. The nationwide ratio is about 84 doctors per 100,000 residents.

But in the San Joaquin Valley, home to about 4.3 million people, doctors are much more scarce – about 47 primary care physicians per 100,000 residents, according to Dr. Tom Utecht, chief medical officer at the Fresno-based Community Health System.

That number is “a little over half of what is necessary to take care of a population,” Utecht said Tuesday in a video press conference. “We have the lowest physicians-per-capita rate in all of California, in the San Joaquin Valley.”

Introduced last month, the Medical Education Act is something of a placeholder for the time being until the Congressional Research Service can weigh in with financial estimates of what is needed in different parts of the country, Costa said. 

A companion version was introduced in March in the U.S. Senate by Sen. Tim Kaine, D-West Virginia, and Sen. Alex Padilla, D-Los Angeles.

At this point, the legislation does not specify how much money will ultimately be sought or how grants would be structured.

Costa said the shortage of doctors in the region “is combined with language barriers, cultural barriers and distances … and that would really go for rural parts of our country regardless where folks live.”

“If you live in rural areas, it’s just more difficult to have access to good quality health care,” he added.

Costa said the legislation, if it can survive a Republican-controlled House and Senate and a Republican president, “would be transformative because it would invest expanded resources to minority-serving institutions and colleges located in rural and underserved areas to establish schools of medicine and osteopathic medicine.”

The bill would also create an avenue for more historically Black colleges and universities, as well as Hispanic-serving institutions, to establish medical education programs, Costa said.

Gray noted that when he was in the state Legislature, he and colleagues “worked to get hundreds of millions of dollars in funding to expand the UC Merced campus, to ultimately secure the funding to put the first medical education building up on campus.”

Gray added that the UC San Francisco’s medical education program in Fresno “is an important part of creating the (medical) workforce of the future for the valley, but more importantly, solving this access to care issue that plagues Valley communities.”

At UC Merced, director of medical education Dr. Margo Vener said there has been a surge of interest in the university’s program that funnels students through an undergraduate program for their bachelor of science degree through a medical school degree in collaboration with UC San Francisco.

“All the students that we are enrolling are from the Valley and for the Valley, because they want to really make a difference in promoting health in their communities,” Vener said. That, she added, is likely to eventually translate to those would-be doctors to stay in the Valley to practice medicine.

“The data suggests that two factors really strongly influence where physicians stay to practice,” Vener said. “One of them is where they’re from, which, of course, is why we’re recruiting students from the Valley for the Valley just to stay (and) be doctors for their community. And the other factor is where you went to residency. Those are the two biggest drivers.”

That’s something that was underscored by Dr. Kenny Banh, assistant dean of undergraduate education at UCSF Fresno. “Regional campuses such as UC Merced and UCSF Fresno not only grow doctors, but they take those doctors, physicians and medical students from their communities in the region, and train them in those regions to go back to be physicians in those areas,” he said.

While the costs of the Costa-Gray legislation are yet to be determined, Banh said there are also costs associated with doing nothing to expand medical education.

“There’s health care costs, regardless of how we work it, if we don’t invest in having an adequate supply of physicians,” Banh said. “There’s a cost on the human that can’t access care” and doesn’t get to a doctor until a condition is not treatable “or with significantly worse morbidity and mortality outcomes.”

“And that cost is borne by health systems taxpayers, one way or the other,” Banh added.

But even if the Costa-Gray bill were to pass in this congressional session, the payoff of home-grown medical schools producing a bumper crop of physicians in the Valley or other deprived parts of the country would be years down the road.

“I think it’s really important to understand why we need to invest now for our future, because it takes so darn long” for a student to go from being a college freshman to a practicing doctor, surgeon or specialist, UC Merced’s Vener said. 

After a four-year bachelor’s degree, a student must then complete four years of medical school, which in turn is followed by a residency of three to five years.

“Then often people will do a fellowship to become, for example, a cardiologist or a gastroenterologist or something like that,” she added.

“If you start investing in just one student now, it’s going to take such a long time before they really are there to take care of you at that moment when you need them to be your gastroenterologist, your cardiologist, your emergency physician, or, dare I say, your family doctor,” Vener said.

That, she said, is why it’s also necessary to expand residency programs that can attract would-be physicians into the region in hopes that they will remain once they complete their training. “We need those doctors now, and that’s why this effort is important,” Vener said, “because this is what will both inspire people to stay, but also inspire people to really come and embrace the communities and serve them.”

In a related development, state Assemblymember Esmeralda Soria, D-Fresno, recently introduced a bill for the University of California system to develop a comprehensive funding plan for expanding the current SJV Prime+ BS-to-MD partnership between UC San Francisco and UC Merced, with the goal of transitioning the program to a fully independent medical school operated by UC Merced.

“We have seen firsthand the impacts of medical workforce shortages throughout the Central Valley,” Soria said in a prepared statement. “AB 58 would help ensure the Legislature is equipped with the information needed to secure appropriate funding for the medical education provided for our community at UC Merced.”
