Phytophthora invasions linked to ecological restorations
Biological invasions are one of the three main causes for biodiversity loss globally, together with urbanization and climate change. Not unlike animals and plants, microbes can become invasive in non-native ecosystems. Some microbial invasions can lead to novel plant diseases with direct and detrimental effects on terrestrial ecosystems. The plant trade, both international and domestic, is thought to be a major pathway for the introduction and spread of exotic plant pathogenic microbes. Some introductions are accidental, but systematic introductions are significantly more detrimental for the integrity of natural ecosystems.
In a new study published in the journal Biological Invasions, Matteo Garbelotto, a Cooperative Extension specialist and adjunct professor in the Department of Environmental Science, Policy, and Management (ESPM), investigates whether multiple species of the plant killer genus Phytophthora—which includes the infamous Sudden Oak Death pathogen—could have been brought into natural habitats during restoration projects. Through one of the first controlled studies on the subject, Garbelotto and Laura Sims, a study co-author at Louisiana Tech University, found that plants used in restoration projects often were infected and killed by one or multiple Phytophthora species.
From surveys of control undisturbed sites near failing restorations, as well as plant production facilities providing the plant stock used in these restorations, the authors were able to conclude that these pathogens were not already present in restored habitats. Rather, they were introduced through plants or soil contaminated in the plant production facilities themselves.
The researchers tested six plant species for the presence of Phytophthora in 14 study sites across three San Francisco Bay Area counties. A statistical analysis found significantly higher percentages of Phytophthora occurrences on plants and soil in restoration sites and adjoining disturbed sites than in control undisturbed sites, where no Phytophthoras were isolated. The researchers found greater rates of disease symptoms and plant death, as well as a lack of regeneration, where Phytophthoras were present.
“All other studies so far simply reported the presence of these soil borne pathogens in restorations, but without any solid experimental evidence that they were introduced through the restoration efforts,” says Garbelotto. “In this light, the paper is transformative. The fact that Phytophthoras were found in all restoration sites studied and on multiple plant hosts shows these are not isolated occurrences, but that habitat restoration projects in the near past have repeatedly and systematically resulted in the introduction of these aggressive pathogens.” He adds that the absence of these pathogens in neighboring unrestored and undisturbed sites suggests that at least some of the species found may be exotic, and particularly deadly, for plant hosts that have not previously encountered them.
“The second key result of our study was the finding that these pathogens are spreading invasively through infested soil and water well outside the borders of restorations”, says co-author Laura Sims. “This indicates that extremely costly restoration projects, rather than restoring the integrity of the ecosystem, may further deteriorate its health, by introducing invasive plant pathogens. Historically, man has never been able to eradicate these pathogens, once they have established in natural habitats. We have shown such establishment is happening in natural habitats near the restoration sites we studied”
The study was partially conducted in the Presidio of San Francisco, a national park site. “Plantings and landscape restorations are a big part of what we do in the Presidio,” says Christa Conforti, biologist and Integrated Pest Management Specialist with the Presidio Trust. “This study shows that restorations have unwittingly introduced plant pathogens that cannot feasibly be eradicated, and that repeated introductions are particularly dangerous. This evidence justifies investing our resources to ensure we take significant precautions when using nursery-grown plants in our landscapes, to help us meet our mission of protecting biodiversity and native ecosystems into the future.”
As a faculty member in ESPM, Garbelotto researches exotic forest diseases, fungal ecology, biodiversity, geonomics, wood decay and tree stability, and the management of forest diseases. He also runs a citizen science initiative in California to find and combat the exotic disease sudden oak death (SOD), known to have decimated native oak and tanoak populations. Garbelotto was featured in Breakthroughs magazine in 2019. The lab he runs also provides diagnostic services and forensic evidence on factors leading to tree failure.
The full study, titled “Phytophthora species repeatedly introduced in Northern California through restoration projects can spread into adjacent sites,” can be found on the Biological Invasions website.

Citizen science SOD Blitz starts April 11 with new COVID-19 safety measures
With Californians sheltering in place to stop the spread of new coronavirus COVID-19, the annual citizen science project to map sudden oak death disease has been redesigned to ensure the safety of participants. The first in a series of SOD blitzes of 2020 will be April 11 in Napa. The events are free.
“We have been able to redesign the 2020 SOD Blitzes to make them a safe and legal activity that allows volunteers to exercise outdoors, and this powerful citizen science program will help us protect our forests' health,” said Matteo Garbelotto, UC Cooperative Extension forest pathology specialist and adjunct professor in the Department of Environmental Science, Policy and Management at UC Berkeley and event organizer.
Sudden oak death disease has killed more than 50 million of the state's iconic oaks and tanoak trees between Humboldt County and Monterey County, threatening survival of several tree species. In 2019 alone, 1 million tanoaks succumbed to sudden oak death, according to 2019 tree mortality data released by the U.S. Forest Service.
“The presence of new SOD strains is alarming and the SOD blitzes are the best, if not the only, program to intercept them before they spread,” Garbelotto said.
SOD Blitz volunteers will register online and take the training online at www.sodblitz.org to learn how to identify SOD symptoms and to carefully collect symptomatic leaves from California bay laurels and tanoaks. Collection and survey materials, which have been prepared in a sterile environment, will be picked up by participants at a local SOD Blitz station conveniently located near a parking lot. They can return samples to the same SOD Blitz station or by mail.
As citizen scientists, volunteers should focus on following safety guidance as well as adhering to research protocols. Social distancing – at least 6 feet away from other volunteers – and clean “housekeeping” rules will be strongly enforced when picking up or returning materials and during leaf collection.
For parents who are home schooling their children, this is an activity that the family can do together.
Garbelotto encourages tree care specialists to participate in the SOD blitzes.
“Besides offering free bay laurel and tanoak tests for their clients, we now offer tree care professionals free enrollment in UC Berkeley Forest Pathology Laboratory's OakSTePprogram, which allows them to test oaks for SOD infection,” Garbelotto said.
For more information, visit www.treefaqs.org or email the organizer of the SOD Blitz in your community (See schedule below).
Sudden Oak Death Blitzes 2020
All collection materials will be provided, but participants need a mobile phone or GPS device to install the free SODmap mobile app.
New format due to COVID-19
1. Training (30 minutes) and sign-up (5 minutes) must be done online at www.sodblitz.org before collecting the sampling materials at the SOD Blitz Stations in the locations specified below. Please sign up before you start the survey, and preferably when you take the online training.
2. Once at your local SOD Blitz Station you can pick up one or two collection packets following the social distancing rules of the State of California clearly specified in the online training.

Volunteers needed to stop SOD from killing oak trees
“Two new dangerous SOD strains are at the doors of our forests,” said Matteo Garbelotto, UC Cooperative Extension forest pathology specialist in the Department of Environmental Science, Policy and Management at UC Berkeley. To assess the movement of SOD, he has mobilized citizen scientists for what he calls “SOD blitzes.” The first in a series of SOD blitzes of 2020 will be April 11 in Napa.
“We had some great results last year and participation continued to be good after 13 years of SOD blitzes,” Garbelotto said.
In Sonoma County, the 2019 SOD infection rate doubled that of 2018, and in Napa County, SOD detection was four times higher than the previous year. In the East Bay, between Richmond and San Leandro, SOD infection spiked – from 1% to 12%. The SOD infection rate tripled – from 6% to 18% on the western slopes of the Santa Cruz Mountains in San Mateo County.
As the disease expands its path of forest destruction, the UC Cooperative Extension scientist says more volunteers are needed to sample trees.
“The disease is moving to new counties outside of the current area of infestation,” Garbelotto said. “Even in our Bay Area neighborhoods, SOD of 2019 is not the same SOD of 10 years ago: different distribution, new local outbreaks, and new hosts are emerging, as the disease becomes more and more established in its new home.”
Garbelotto sees the SOD blitzes as the only hope for early detection of the new SOD strains.
“If these new strains arrived and spread in our forests, they could deliver a fatal blow to our forests,” he said. “By collecting symptomatic plant material in their neighborhoods, volunteers will make the most significant contribution possible to intercept these strains.”
Volunteers are taught to identify SOD symptoms and to carefully collect symptomatic leaves from California bay laurels and tanoaks. Participants in the SOD blitzes will be asked to quantify their efforts to stop SOD to show public interest in saving oaks and tanoaks when applying for funds to defeat the tree-killing disease.
Garbelotto is encouraging tree care specialists to participate in the SOD blitzes.
“We have enhanced the benefits for tree care professionals who participate in the blitzes,” Garbelotto said. “Besides offering free bay laurel and tanoak tests for their clients, we now offer them free enrollment in UC Berkeley Forest Pathology Laboratory's OakSTeP program, which allows tree care professionals to test oaks for SOD infection. It could be enormously beneficial to everybody.”

Are Blackouts Here to Stay? A Look into the Future
(E&E News) Anne C. Mulkern, Nov. 15
…Throughout the United States, between roughly 2000 and 2010, about 75% of homes that burned in wildfires were located in the WUI, said Van Butsic, a land use specialist at the University of California, Berkeley. The rest was mostly in rural areas, with about 2% in cities.
People go back after they lose homes, Butsic said. He surveyed the 28 largest fires in California from about 1975 to 2005, and through aerial photos tracked what was rebuilt. About 90% of destroyed homes were rebuilt within a decade, he found. New homes also filled in large tracts of undeveloped land in formerly burned areas.

Climate Considerations for Processing Tomatoes
(AgNet West) Nov. 15
Research models show that increases in overall temperatures in California will have a direct effect on how some crops are going to be produced in the future. In one study looking at processing tomato production in the Central Valley, researchers found that changing temperatures will likely have a noticeable impact on the timing of the growing season.
“We looked at the data all the way starting from 1950, into the future by 2030-2040 and see how the time of maturity is changing,” said Tapan Pathak, UC Specialist in Climate Adaptation in Agriculture. “What we saw is, in general the time from emergence to maturity, the timeframe for processing tomatoes in that region, is going to shrink down almost by two to three weeks.”

What's Growing On: American rose trials test sustainability
(Stockton Record) Marcy Sousa, Nov. 15
Did you know San Joaquin County Master Gardeners have been part of a National Rose Trial since 2018? The trial is part of the American Rose Trials for Sustainability (A.R.T.S.) program that has trial sites across the United States. It was initiated in 2012 by individuals representing multiple rose stakeholder groups, including: industry, the scientific community and public gardens. There are only two Mediterranean climate trial locations and both are in California. The trials at the Fullerton Arboretum started in 2019 and the UC Cooperative Extension office in San Joaquin County began in 2018.
…Our Environmental Horticulture Advisor, Karrie Reid, has been managing and overseeing the trial since 2018. Our roses were planted in unused turf areas that were converted to the trial grounds. One of the selling features of converting the turf sections was the calculated water savings: 3,656 square feet of turf used 103,000 gallons of water, while 60 roses in the same area on drip use 6,175 gallons, a 94 percent savings. Trial sites are covered with a 3-inch layer of wood mulch.
Report: California ag is a major economic driver for the state
(Agri-Pulse West) Brad Hooker, Nov. 13
A new report by the University of California Division of Agriculture and Natural Resources (ANR) adds new dimensions to the “massive economic juggernaut” of the California agricultural industry. The findings reveal that agriculture contributed more than $263 billion to the economy in 2018 through direct sales and employed more than 1.2 million people, while benefiting urban and rural regions alike.
The report examines the entire “working landscape,” which also includes fishing, forestry, mining, outdoor recreation and renewable energy, in addition to agricultural distribution, production, processing and support. Together, the sectors represent $333 billion in sales, 1.5 million jobs and 6.4% of the total California economy, outranking the healthcare, real estate, construction and retail sectors. Agriculture accounted for 85% of the working landscape businesses and 79% of the sales income. According to ANR Vice President Glenda Humiston, the working landscape likely surpasses the finance sector as well.
UCCE Addressing Watergrass Issues in California Rice Fields
(AgNet West) Brian German, Nov. 13
Researchers from UC Cooperative Extension (UCCE) are looking closely at the watergrass issues in California rice fields to get a better understanding of the problem. Watergrass has historically been a fairly common weed species that growers face, however in recent years the issue has been compounded by a number of factors. Several watergrass species have demonstrated resistance to the materials available and it appears that one or two new species may have emerged.
“In the past few years watergrass is becoming more and more of a problem, whether it's the ones that we know that we have or these possible new species,” said Whitney Brim-DeForest, UC Rice Farm Advisor serving Sutter, Yuba, Placer, and Sacramento Counties. “It's just becoming more difficult to control with the herbicides that we have.”

Experts Warn Of Surge In Sudden Oak Death Infections In North Bay
(KPIX) Wilson Walker, Nov. 12
“And then, of course, these limbs that have just fallen off,” said Kerry Wininger of UC Cooperative Extension as he stood beneath a dying tree in Sonoma County's Fairfield Osborn Preserve. “And big patches will come out at once.”
Wininger is with the UC team working to measure the problem, and the numbers are up dramatically. She oversees a yearly survey conducted by volunteer citizen scientists.
…“For Sonoma County in general, Sudden Oak Death numbers look about double where they were last year,” said Wininger. “So it's actually increasing at a rate a little bit faster than we would expect.”

California's Wildfire Policy Totally Backfired. Native Communities Know How to Fix It.
(Mother Jones) Delilah Friedler, Nov. 11
…“We aren't anywhere near bringing fire back at the scale we need to,” says Lenya Quinn-Davidson, a fire advisor with the University of California Cooperative Extension who helped lead that burn. “It's important to push forward with a grassroots model that empowers people to do the work, instead of having bottlenecks with the agency that's in charge.”
The Humboldt County Prescribed Burn Association, which Quinn-Davidson leads, was the first organization of its kind in the West when it started in 2018, and has already inspired similar groups to start up in northern California's Plumas, Nevada, Sonoma, and Mendocino counties. These groups bring landowners and neighbors together to provide the manpower that controlled burns require. Quinn-Davidson says she's hosted 25 lecture and field-based workshops in the past year to increase people's comfort with prescribed fire, and in the past two years, she's led 20 burns on private lands.

Insect entrepreneurs use almond hulls as feed source for bugs
(Daily Democrat) Ching Lee, Nov. 8
…Maurice Pitesky, a UC Cooperative Extension veterinarian and specialist in poultry health and food-safety epidemiology, conducted an experiment two years ago on pastured layers, feeding up to 20% of the birds' diet with soldier fly larvae “with no change in welfare, egg quality, mortality.” The larvae feed provides methionine, an essential amino acid for poultry, and has “significant potential” to increase poultry production while freeing “more corn and soy calories for humans,” he said, though he warned of two caveats: economics and consistency of manufacturing the feed.

Sudden oak death spreading fast, California's coastal forests facing devastation
(San Francisco Chronicle) Peter Fimrite, Nov. 7
…The rate of trees infected almost doubled in 2019 — from 3.5% to 5.9% — and was 10 times higher in some places compared with the 2018 survey, said Matteo Garbelotto, the director of the UC Berkeley Forest Pathology and Mycology Laboratory, which tested leaf samples taken by 422 volunteers.
...“There was a significant increase in infection rates over last year, but that's not totally surprising because we had a lot more rainfall,” Garbelotto said. “But it was a surprise to see them all at once. It's telling us we are entering a different phase of the disease, where the organism isn't really establishing itself in new areas, but is showing itself more when weather conditions are favorable.”
We mapped every wine country fire. They're larger and more destructive than ever
(Los Angeles Times) Priya Krishnakumar, Nov. 7
…Why is this happening? Scientists point to rising temperatures and the effects of Santa Ana and Diablo winds on increasingly dry terrain.
“In a way, climate change is priming the landscape to ignitions,” said Max Moritz, a wildfire specialist at UC Santa Barbara.
…Experts say many of the losses are due to increased development, as more and more homes have been built in areas prone to fire.
“The homes are the fuels,” Moritz said. “We see these burned neighborhoods where there are still shrubs and trees, and it's clear the homes propogated the fire.”

Power shutoffs leave some farmers feeling ‘helpless'
(Ag Alert) Ching Lee, Nov. 6
… "If they've lost cooler capacity or the ability to wash product, not only are they taking a hit on the expense side, but they have less to sell," Placer County sheep rancher Dan Macon said. "That's kind of a double whammy for a number of folks."
… Wineries also are running into this problem, said Anita Oberholster, an enology specialist for University of California Cooperative Extension. Those operating on generators are running low on fuel and can't get it to their wineries, which need power not only to process fruit but to control temperature during the fermentation process. Because yeast can generate a significant amount of heat during fermentation, an inability to control temperature could affect the quality of the wine, she said.
… "People are making the investments they need to make, but it's stuff that's outside the normal course of business, and I think there'll be some financial impacts from that in terms of this season's profitability," he said.
As a UCCE livestock and natural resources advisor, Macon said the outage has prompted him to start sending a survey to farmers in an effort "to catalog resources that are out there and available for sharing in situations like this," whether it's generators, water-hauling capacity or, in the case of fire, the ability to load livestock quickly and safely.
