UC Agriculture and Natural Resources vice president Glenda Humiston welcomed a delegation of Chinese agricultural scientists to UC ANR's Intermountain Research and Extension Center in Tulelake in June, reported Danielle Jester in the Siskiyou Daily News.
"They're trying to improve their agriculture," Humiston said. "We need all farmers and ag working together, and we need a good working relationship with China – there's a big market there.”
During her opening remarks, Humiston said Chinese farmers faced many of the same issues as those in the U.S.
"They are responding to global climate change, drought and pests while trying to improve food security and water use efficiency," Humiston said. "They see UC Cooperative Extension as an effective research model; we hope that scientific collaborations will accelerate solutions and help maintain relations for California agriculture with China."
The group toured the Intermountain Research and Extension Center, the northernmost of UC ANR's nine research and extension centers.The 140-acre facility is four miles south of the Oregon border. Research at the center is focused on irrigated field and vegetable crops, weed, insect and disease management, water conservation and plant fertility.
During the tour of the station, one of the Chinese scientists asked what factors the researchers look at to determine the health of the soil. In response, center director Rob Wilson listed the soil's nutrients, its bulk density, pH, organic matter content, carbon to nitrogen ratios, existence of microbes, and existence of disease in the soil, Jester reported.

Abnormal Weather Takes a Toll on California Olive Crop
(Ag Net West) Brian German, May 30
The late winter freeze caused significant issues for several different commodities throughout the state and has been especially problematic for the California olive crop. The fluctuating temperatures have created substantial concern among the industry as bloom looks to be far below normal levels.
“Overall we're a little on the pessimistic side. The bloom, on the whole, has been pretty poor, many orchards actually have a very light, to next to no bloom at all,” said Dani Lightle, Cooperative Extension Orchard Systems Advisor for Glenn County. “There's an orchard here or there that looks pretty good, but on the whole, it is a little bit dismal.”

…Eric Focht who is a staff research associate in the lab of Mary Lu Arpaia at UC Riverside through UC Agriculture and Natural Resources and the Department of Botany and Plant Sciences tells L.A. Taco that the recent avocado economy boom is “similar to what we see today with something like bitcoin.” He helps run a breeding program at UCR studying different avocados varieties, focusing mostly on Hass avocados but also looking at other less known versions of the popular fruit.
In short, he is working on breeding the perfect avocado that tastes great and is easier, faster, and less water-dependent to grow. This year is shaping out to be a good one for avocados, but this issue is always one to keep in mind.
Focht states that in the future, there will likely be more variety available in the mainstream marketplace. One varietal that Focht gets excited about is the Reed avocado which has now been popping up in places such as Whole Foods. It's known for its round, dinosaur egg shape and is about the size of a softball. It has a relatively large seed but the edible flesh is sometimes double or even triple that of a Haas that can make a lot more people happier per individual fruit.
(Chico News & Review) Ashiah Scharaga, May 24
When drifting clouds dapple the sky and vibrant wildflowers—tickled pink buds, honey-hued petals and virent stems—awaken in the verdant fields of Table Mountain, explorers quicken their pace. They spot trickling streams and grazing cattle. Occasionally, they look straight down, turning anxious eyes to their mud-slicked heels—did they step in one of the fertile cow-pie mines littered across the landscape?
That may seem a nuisance, but it's a necessity. Tracy Schohr, a livestock and natural resources adviser for University of California Cooperative Extension, said the natural magic of the popular Butte County recreational spot is made possible because of a long-standing grazing program. “If cattle were not actually on Table Mountain Ecological Reserve,” she said, “essentially those invasive species would choke out those native plants, and they wouldn't be there.”
… In the past, grazing was misunderstood and primarily viewed as destructive, said Dave Daley, a fifth-generation Butte County cattleman and associate dean of Chico State's College of Agriculture. He credits changing perspectives to the development of grazing science, fueled by people such as Schohr and Kate Wilkin, a UC Cooperative Extension forestry, fire science and natural resource adviser for Butte, Yuba, Sutter and Nevada counties. (Schohr covers Butte, Plumas and Sierra counties.)
Sheep Shearing 101: Why Aspiring Shavers Flock to This California School
(KQED) Tiffany Camhi, May 23
…“We try to get the students shearing the first day because they make a lot of mistakes,” says John Harper, head of the UC Cooperative Extension Sheep Shearing School in Hopland.
Harper says if you can make the right moves with your feet, everything else falls into place.
“We're dancing instructors,” says Harper. “It's like 'Dancing With The Stars' on steroids, but with sheep.”
Around this time of year, hundreds of thousands of sheep in California need to have their wool shaved off. But Harper says there's a shortage of sheep shearers worldwide.
That's why he started the school in Hopland about 25 years ago.
Dan Macon of the California Wool Growers Association says the growing popularity of backyard flocks in California (usually just a handful of sheep) is adding to the demand for shearers, too.
“Infrastructure of the sheep industry is a key component,” says Macon. “Having people with that kind of skill and willingness to work hard is desperately needed.”
AUDIO: Hey, Salad Lovers: It's OK To Eat Romaine Lettuce Again
(NPR Morning Edition) Allison Aubrey, May 23
…After a big foodborne illness outbreak linked to baby spinach back in 2006, the leafy greens industry put in place a number of procedures to prevent contamination. "Prevention became the major focus after that outbreak," says Michele Jay-Russell, a food safety researcher at the University of California, Davis.
"They set up intensive testing protocols to monitor water quality," Jay-Russell says. The industry also agreed on standardized setbacks — or buffers — to separate growing fields from livestock operations, which can be a source of E.coli contamination. "You want a safe distance from where you're growing fresh produce and where you have concentrations of animals, like on a feedlot or dairy," she says.
Are avocados toast?
(Grist) Nathanael Johnson, May 22
…When Katherine Jarvis-Shean was a doctoral candidate researching the decline of cold winters a few years back, she thought more farmers should be freaking out. “I used to think, ‘Why aren't you guys more worried about this? It's going to be the end of the world.'”
After all, many fruit and nut trees require a good winter chill to bear fruit. But after spending a few years as an extension agent for the University of California — working directly with farmers and translating science into techniques they can apply on the land — she understands better. It comes down to this: Farmers have a ton of concerns, and the climate is just one of them.
“If you decide what to plant based on climate, but then can't make the lease payment, that's not sustainable,” Jarvis-Shean said.
Lanternflies Eat Everything in Sight. The U.S. Is Looking Delicious.
(New York Times) Zach Montague, May 21
…Native to Asia, lanternflies first appeared in Pennsylvania in 2014. Despite a quarantine effort, they have also been discovered in small numbers in New York, Delaware and Virginia.
… “Most pests deposit their eggs on their host plant, or very close, so they already have food available,” said Surendra Dara, an adviser at the University of California Cooperative Extension.
“Those that have the advantage of being able to lay eggs on non-plant material obviously have a better chance of surviving and spreading,” he added.
Garbanzos are catching on in Yolo County
(Woodland Daily Democrat, Ag Alert) Bob Johnson, May 19
…“The largest part of our crop goes to canning, maybe 90 percent,” said Paul Gepts, UC Davis plant sciences professor and legume breeder. “California can only compete with high quality products. We have other varieties with higher yields, but the seeds are too small. The growers get a premium for larger, high quality seeds.”
Gepts developed the two newest UC garbanzo varieties, Vega and Pegasus. Both have large, attractive seeds well suited for the canning market, and both have resistance to Ascochyta blight, a fungal disease that can devastate the crop.
… “I think growers are more interested in garbanzos because it's a winter crop, and wheat prices are low,” said Rachael Long, UC Cooperative Extension farm adviser in Sacramento, Solano and Yolo counties. Long is finishing up UC's first Garbanzo Production Manual, which should be available before the end of the year.

Kale, Not Jail: Urban Farming Nonprofit Helps Ex-Cons Re-enter Society
(New York Times) Patricia Leigh Brown, May 17
Even by the standards of the Bay Area, where sourcing local, organic chicken feed is seen as something of a political act, the spectacle of 30,000 fruit and nut trees being tended by formerly incarcerated orchardists is novel.
…Jennifer Sowerwine, an urban agriculture specialist for the University of California Cooperative Extension at Berkeley, said that Ms. Haleh and Mr. Raders have “shifted the conversation around food justice.”
“It's not just about food security, but the security of providing living wages,” she said. That's no mean feat in a foodie monoculture.
Tough winter weather devastates local cherry, blueberry crops
(Bakersfield Californian) John Cox, May 16
It's hard to say at this point just how much damage blueberry fields and cherry orchards sustained during the winter, said Ashraf El-kereamy, viticulture and small fruits advisor with the University of California Cooperative Extension in Kern County.
Machines take over for people at Napa vineyard
(Capital Press) Tim Hearden, May 14
In the heart of the Napa Valley, a vineyard produces fine Cabernet Sauvignon with virtually no help from laborers.
The 40-acre “touchless vineyard” was established by Kaan Kurtural, a University of California Cooperative Extension specialist who has devoted much of his career to improving production efficiency in vineyards as labor shortages have worsened.
…When Kurtural started experimenting with vineyard automation 10 years ago, his primary goal was to save growers money in labor costs, he said. But since then, research has shown that grape quality is superior, largely because the tall canopy protects grapes from sun damage, he said. The system also uses less water than others, he said.
Dozens of strawberry growers gather in Santa Maria to learn latest industry advancements
(KSBY Staff) May 9
More than 100 farmers and growers took park in a meeting teaching them on the best way to grow a healthy strawberry.
The University of California put on the annual event which was free to the public.
Growers discussed improvements handling weeds, disease, and insects.
The Santa Maria Valley is the second largest strawberry growing area in California after the Salinas Valley.
The crop means a lot to people in Santa Maria.
"We've got a number of challenges to the California strawberry industry and we're doing are best to work together," said Steven Fennimore of University of California Cooperative Extension Agriculture and Natural Resources. "I'm optimistic that we'll find some satisfactory solutions."
Growers talked about all kinds of different ways to boost their crop including ways of using images from aircraft to detect stress in plants.
Pesticide Use on California Farms at Near-Record Levels
(Fair Warning) Paul Feldman, May 9
…Some experts say long-term changes in the mix of items farmers produce in California, including increases in almonds and other high value crops, give the agriculture industry the incentive to use more pesticides. Such crops present “a larger economic risk if pests are not controlled,”said Brad Hanson, a weed specialist at the University of California, Davis, plant science department.
Jim Farrar, director of the University of California's statewide integrated pest management program, added that more pesticides are needed when “you move from something like alfalfa and sorghum for dairies, where cosmetic injury isn't a problem … to something like oranges where if there's a blemish on the rind you get downgraded even if the orange is perfectly healthy.”
Cherry growers expect lighter crop yields
(Ag Alert) Ching Lee, May 9,
…Kari Arnold, a University of California Cooperative Extension farm advisor in Stanislaus County, said she's careful not to paint the 2018 cherry season as a disaster year "because it's really not." The crop may not be as robust, she said, but this was somewhat expected, because last year's crop was so big.
What wasn't expected, she said, was the freeze in the spring, which "did cause some damage to flowers." But the damage varied depending on the location of the orchard and whether growers were able to apply frost protection, she added.
"It's still going to be a good crop," she said. "It may not be the same as last year, but they're going to be good cherries. They're probably going to sell at a higher price because there'll be less of them."
She said she's concerned that word of it being a light crop may scare away field help, adding that "it's hard enough to get field labor in the first place anymore, because labor is becoming more and more difficult to come by and more difficult to keep."
Peak Avocado Is Yet to Come
(The Atlantic) Cynthia Graber, Nicola Twilley, May 9
…Its partners in evolution—the giant, elephant-like gomphotheres and three-ton ground sloths that dined on its fruit in return for transporting and then pooping out its giant seed—went extinct soon after the first bipedal apes arrived in the region. Rodents, jaguars, and eventually humans stepped in as dispersal mechanisms, albeit significantly less effective ones. The flourishing avocado forests that carpeted much of Mesoamerica dwindled and died out. And, as Mary Lu Arpaia, who runs the avocado breeding program at the University of California at Riverside, explained, the avocado became a backyard fruit, enjoyed by first the indigenous peoples and later the conquistadors, but rarely cultivated intensively—until recent decades.
Climate change ruining California's environment, report warns
(SF Chronicle) Peter Fimrite, May 8, 2018
“If I were going to look across North America, ground zero for climate change is the Arctic. It is just changing really, really rapidly,” said Steven Beissinger, professor of conservation biology at UC Berkeley. “But California is an important laboratory to understand the effects of climate change on biodiversity.”
More illnesses with later onset dates linked to romaine outbreak
(The Packer) Ashley Nickle, May 8, 2018
Richard Smith, a University of California Cooperative Extension advisor based in Salinas, also said the outbreak is hurting sales.
“It's having an effect,” Smith said May 7. “This is the problem — lettuce is pretty expensive to grow, and you've got to cover your costs. You can lose money, at this point the bigger growers can afford to lose for a period of time, but then they've got to make it up, and it just makes it hard. We're not sure how the year's going to go.
“I guess the good news is that the consumers are being sophisticated enough to be focusing on the romaine (versus all lettuce) ... The reality is I guess the FDA doesn't want to clear romaine yet because they think that the lettuce from Yuma might have a 21-day shelf life, so until the FDA clears it and then that news gets clearly articulated, I think it's going to be a damper.
AEI economists say farmers have ‘beef' with Trump
(Hagstrom Report) May 7, 2018
…Daniel Sumner of the University of California at Davis also told The Hagstrom Report that farmers hurt by the administration's trade policies have "a beef" with Trump.
Sumner said that even though the tariffs on Chinese steel and aluminum have not yet gone into effect, California farmers including wine and almond producers are already worried. "Even if the tariffs don't happen, the rhetoric has effects," he said.
Sumner also said that Mexican buyers of U.S. dairy products — "reasonable business people in Mexico" — began months ago to contact New Zealand dairy producers about becoming a supplier because the Mexicans are worried about the impact of the North American Free Trade Agreement renegotiation.

Egg prices plunge as supplies rebound
(Capital Press) Tim Hearden, May 4
Commercial egg prices in California are plummeting, and a slow global economy combined with a rebounding chicken flock after last year's devastating avian flu outbreak are among the contributing factors.
…At first, Midwestern egg producers that didn't want to retrofit their barns simply avoided California. Those that did want to market to California found confusion in what actually constituted a Proposition 2-compliant cage, said Joy Mench, a University of California-Davis animal science professor.
“(T)he wording of Prop. 2 does not allow it to be regulated, so there is no official definition of what it means,” Mench said in an email. “That will have to be decided in the courts, either because there is a lawsuit or because someone is prosecuted.”
In enforcing the initiative, the CDFA uses the federal Shell Egg Food Safety rule, whose space requirement is larger than the United Egg Producer guidelines that most of the other states use, noted Maurice Pitesky, a poultry specialist at the UC-Davis School of Veterinary Medicine.
Farming takes center stage at Yolo County Fairgrounds
Woodland Daily Democrat) Cutter Hicks, May 4
Field trips to the fairgrounds led to a farming experience for students as the Yolo County 4-H and Farm Bureau hosted its 10th annual Farm Connection Day to kick off the Spring Show this weekend.
The four-hour event Friday featured more than 100 agricultural displays and hands-on activities for kids of all ages as nearly 2,500 visitors walked through the gates.
Farm Connection Day was open to the public and more than 200 4-H students teamed up to host the event — with a little help from adult volunteers. Their focus was to teach students of Yolo County the aspects of the organization before judging shows later that day.
DeAnn Tenhunfeld, a Farm Connection Day organizer, said that the attendance was the largest seen since she founded it in 2008.
Frost damage varied for California nut trees
(Farm Press) Robyn Rominger, May 2, 2018
Some almond growers experienced frost damage from recent freezing conditions, say University of California experts.
“There's really a lot of damage,” says Katherine Jarvis-Shean, UC Cooperative Extension orchard systems advisor for Sacramento, Solano, and Yolo counties. “The earlier varieties really took a hit. Some trees even dropped their nuts due to frost damage. It's pretty bad in some orchards.”
… Bruce Lampinen, UCCE almond and walnut specialist, measured temperatures in an almond trial at Davis, and notes that “Feb. 20 and 24 were the coldest days. It was very problematic because that's when the trees were in full bloom.” At full bloom, temperatures below 28 degrees F. can cause crop loss.
…Phoebe Gordon, UCCE orchard systems advisor for Madera and Merced counties, says, “From what I've seen and heard, the damage has been variable. Some orchards weren't hit that hard, and others were hit very hard. I think it depended a lot on micro-climate and what stage the trees were in. They become more susceptible to frost damage as they transition from dormant to full bloom, and to nut set. I don't think we'll really know until ‘June drop' is finished what the final load is.”
Dani Lightle, UCCE orchard systems advisor in Glenn and Butte counties, says, “Almonds were right in the middle of full bloom when the frost happened. Most of the orchards in my area seem to have escaped. We didn't seem to cross the threshold to where there was heavy damage. Of course, there are exceptions, but by and large we came out better in the end than we thought we would.”
New weapon in fight against walnut blight
(Farm Press) Robyn Rominger, May 2, 2018
Walnut growers have a new tool to help manage blight disease in their orchards — Kasumin 2L, manufactured by Arysta LifeScience, is the trade name for kasugamycin, and is available as part of a strategy to control the disease.
The new bactericide was discussed at a recent University of California Cooperative Extension breakfast meeting at Yuba City. “It's great to have another chemistry in the rotational loop for blight management in walnuts,” says Emily Symmes, UCCE integrated pest management advisor.
The tenth Americas Competitiveness Exchange on Innovation and Entrepreneurship (ACE) will be held for the first time in Northern California in October. To promote partnerships, the exchange will bring economic and political leaders from across the Americas and beyond to visit Northern California's world-class innovation and entrepreneurship ecosystems, and to experience the best California has to offer in food, wine and local products. The milestone “ACE 10” is sponsored by the University of California Agriculture and Natural Resources, Central Valley AgPlus and other California partners.
From Oct. 21 to 27, approximately 50 high-level economic and political leaders from across the Americas, selected through a competitive application process, will participate in ACE 10, which will highlight innovation and entrepreneurial activity.
ACE 10 program themes include:
o Improving health: Bioscience, food safety, healthy food access and nutrition
o Feeding the world: Sustainable food systems & communities, food security, ag tech
o Maximizing resources: Resource management, water and energy, waste-to-energy uses
o Fostering resiliency: Environmental sciences, mobility, global leadership
o Innovation ecosystems: Innovation communities, supporting entrepreneurs, financing ventures
“The University of California is pleased to host the milestone ACE 10 in Northern California to highlight our world-class innovation and entrepreneurship that drives local and regional economic development,” said Glenda Humiston, UC vice president of agriculture and natural resources. “We look forward to building new and lasting partnerships across the Americas.”
The ACE 10 program will start in San Francisco at UCSF's renowned biotech research center and start-up incubator in Mission Bay, followed by a visit to NASA Ames Research Center. The tour includes stops in Santa Cruz, Monterey, Salinas, Fresno, and Davis, and will conclude in Sacramento. Site visits will focus on food and agriculture, water and energy technologies, life and environmental sciences and advances in manufacturing.
“It's a tremendous honor and important opportunity for Northern California to host the 10th Americas Competiveness Exchange,” said Valley Vision's chief executive Bill Mueller. “Hosting this global delegation gives California not just the chance to showcase our assets, but also provides an unmatched platform to build global economic and research alliances.”
Gabriel Youtsey, UC ANR chief innovation officer agrees. “Innovation and entrepreneurship are California's biggest ‘exports' to the world and we aim to set off the next wave of innovation in our state's distinct areas of strength: food, agriculture and life sciences.”
The agenda is designed to provide the delegates opportunities for interactive learning, sharing of best practices, networking and partnership development as they travel from the coast to the inland areas of the state. “During the tours, our visitors will discover opportunities and create new collaborations that will continue to flourish long after they return to their home countries,” Humiston said.
ACE toured the Arizona-Southern California corridor in 2016. The most recent exchange, ACE 8, was held in Florida in December 2017. ACE 9 will be held in Israel and Germany this June where the baton will be passed to Humiston to take lead on ACE 10.
Valley Vision—a civic leadership organization headquartered in Sacramento that is committed to building a prosperous and sustainable future—is a co-host for ACE 10, along with UC ANR. The Northern California leadership team also includes California State University, Fresno and California State University, Chico; the cities of Davis, Fresno, Sacramento, Salinas, San Francisco and Santa Cruz; Bay Area Metro and Monterey County. The successful bid to host ACE 10 is an outgrowth of the Central Valley AgPlus food and beverage manufacturing consortium.
The principal ACE convening institutions are the U.S. Department of Commerce, through the International Trade Administration (ITA) and the Economic Development Administration (EDA); the U.S. Department of State; the Government of Argentina;and the Organization of American States (OAS) as the Technical Secretariat for the Inter-American Competitiveness Network (RIAC). ACE is a core component of the Work Plan of the Inter-American Competitiveness Network.
Past examples of mutually beneficial partnerships developed by ACE exchanges include:
• Research centers and co-ops such as Organic Valley in Wisconsin and Escuela Superior Integral Lecheria (ESIL) of Villa María in Cordoba, Argentina, working on business and export development in the dairy industry;
• Young entrepreneurs from UNITEC Honduras interacting and collaborating with the entrepreneurship ecosystems led by UC San Diego;
• An industrial internship program between Canada and Mexico through Mitacs, a Canadian not-for-profit research and training organization, and Mexico's National Council of Science and Technology (CONACYT).
USDA Secretary Sonny Perdue held a town hall at World Ag Expo in Tulare on Feb. 13 to listen to suggestions for the upcoming Farm Bill. VP Glenda Humiston was among those present for the discussion.
Todd Fitchette of Western Farm Press wrote: “While trade, labor and regulatory issues may top the list of agricultural policy issues Perdue faces in Washington D.C., Glenda Humiston, Vice President of the University of California Agriculture and Natural Resources Division of the state's Land Grant university, stressed the importance of adequate research funding and federal definitions of rural versus urban, which she said is having detrimental impacts across California on important program funding.
“Humiston said that while UCANR has a ‘proud tradition of research in California,' the university is plagued by reduced budgets at the same time the state is plagued by a new invasive pest every several weeks. She said for the university to stay ahead of these issues and to help growers in these and many other areas, additional funding is vital.
“The United States is losing the battle over agricultural research with China, which spends more in that sector, Humiston says. She continues to trumpet the idea of greater broadband access to rural areas of the state as new agriculture will demand internet upgrades for technology like sensors and driverless spray rigs.”
In private communication, Fitchette mentioned that widespread applause broke out across the audience in response to Humiston's comments.
“If a county has one town that has 50,000 population in it, the entire county is labeled metropolitan for purposes of allocating funding,” Humiston said, wrote Chelsea Shannon of the Hanford Sentinel.
Matthew Sarr of the Porterville Recorder also covered the event.

Ag leaders, scientists set priorities to prevent invasive pest threats to the environment and economy
The gypsy moth, an interloper from Europe and Asia, is threatening California's majestic oaks in Ventura County.
Invasive desert knapweed, which comes from Africa, has made its first North American appearance in in California's Anza-Borrego Desert, where it has started to crowd out native plants.
Asian citrus psyllids are slowly spreading the devastating huanglongbing disease in Southern California citrus.
River rats from South America, called nutrias, are munching voraciously on wetland plants in some areas of Stanislaus, Merced and Fresno counties.
These are just a few of the insects, weeds, animals and diseases that have entered the state of California from elsewhere on the globe, causing tremendous ecological damage and huge economic losses to agricultural crops, which ultimately affect every resident of California.
Based on historical data, a new invertebrate species establishes itself in California about every six weeks, on average. They don't all become serious pest problems, but many evade eradication efforts, disrupt carefully balanced integrated pest management programs, hijack sensitive ecosystems, and spoil valued recreational resources and urban landscapes.
A diverse group of university scientists, federal and state government representatives, county agricultural commissioners and non-profit organization leaders who are battling these pests converged at a summit in the state capitol Jan. 11 and 12 to coordinate their efforts, pool intellectual resources, and plot a strategy for protecting agricultural crops, natural resources, unique ecological communities, cityscapes and residential neighborhoods.
“We are a big, beautiful, special place, blessed with great weather and diverse geography,” said California Department of Food and Agriculture Secretary Karen Ross at the summit. “That means a lot to our many visitors – including pests.”
“We know that collectively, we have the tools and expertise to prevent invasive species from entering California, spreading and becoming established,” Humiston said. “I am so pleased with the numbers of people here today, and the expertise that you bring.”
A fundamental component of the fight against damaging invasive species is research, Humiston said, adding that the European grapevine moth in an apt example. The pest was detected in California's wine country in 2009, and later found as far south as Fresno County. A multi-agency collaboration responded quickly.
UC ANR academics studied the moth's biology, life cycle, host range and proven management practices. They developed a pest management program that relied on mating disruption with pheromones and application of carefully timed insecticides. In short order, the moth population plummeted, and the state was declared free of European grapevine moth, lifting a quarantine, enhancing farmers' ability to export its product, and preserving the communities' economic wellbeing.
“This multi-agency collaboration contributed to a successful, science-based response plan to a serious pest threat,” Humiston said.
She noted, however, that prevention is the best option.
“This is critical,” Humiston said. “Once the pests are here, they cost us millions upon millions of dollars to manage, not to mention the devastation and destruction inflicted on our crops, natural resources and the damage to local economies.”
In 2010, CDFA created a strategic framework for addressing California's ongoing invasive pest problems and potential future introductions. Successful implementation of the framework requires partnerships involving government from the state to local levels, the agriculture industry and commodity groups, non-governmental organizations committed to the environment, and researchers at UC and other universities.
UC Cooperative Extension advisor emeritus John Kabashima was instrumental in bringing the summit to fruition. Kabashima, who retired in 2015, continues to lead a battle against invasive shot hole borer pests in Southern California. The insects, originally from Asia, are killing thousands of Southern California trees, and have the potential to kill millions of trees in urban areas, natural areas and even on farms in parts of the state as far north as Sacramento.
“We convened this meeting to bring together experts in the field and people who are feeling the impacts,” Kabashima said. “We're trying to start a 21st century invasive pest program that would then be implemented and funded to address the urgent issues before they cause any more devastation.”
At the end of the two-day summit, the participants voted to decide the most pressing issues and best strategies to take forward to their agencies, coalitions, research groups, legislators and constituents. Key strategies that emerged were:
- Analyze the economic impacts of invasive species management and the cost of “doing nothing.”
- Develop and maintain statewide surveys and map high-risk surveys.
- Increase funding to study invasive species' biology.
- Create a standing rapid response workgroup to guide response to new invasive species. Fund a rapid response emergency fund.
- Enact regulations to control high-risk vectors, such as soil, green waste, gravel, forage, straw and firewood.
- Formalize the Invasive Species Council of California (ISCC) and the California Invasive Species Advisory Committee (CISAC).
Mark Hoddle, UC Cooperative Extension biological control specialist and director of the Center for Invasive Species Research at UC Riverside, said the summit was a valuable part of the ongoing battle against invasive pests.
“It's good to see the number of agencies and organizations involved with invasive species issues,” Hoddle said. “I'm impressed with the energy in coming up with these priority lists.”
Summit outcomes will include sending recommended action items to the Legislature for funding consideration.
“Without financial support, many of the management tools that prevent unwanted incursions, find and monitor incipient pest populations, and develop sustainable, cost-effective management programs won't be possible,” Hoddle said.
