Important Invasive Species Updates from UC IPM

Invasive pest species threaten California's natural environment and can have an impact on public health. UC Master Gardeners can help spread the word about these invasive species and how to limit their introduction, spread, and harm. Learn to recognize these pests and distinguish them from look-a-likes. Please share these resources widely with the UC Master Gardener and your local community.

For any of the pests below, please direct clientele to report a finding with their local County Agricultural Commissioner to the CDFA Report a Pest Hotline.

Emerald Ash Borer

The emerald ash borer (or EAB) is an invasive insect that has been found for years in numerous states across the country, but until recently had not been found on the West Coast. In June 2022, EAB was detected in Oregon. This insect feeds on all species of ash trees and has the potential to devastate whole communities of trees.

UC IPM is working on a new web page to cover EAB, but for the time being, please see the California Department of Food and Agriculture website for information about its biology and national distribution.

Spotted Lanternfly

In California, we've been on the lookout for the spotted lanternfly (SLF) for several years. In July 2022, a truck carrying firewood into California from New Jersey (I know, why?) was inspected at a CDFA Border Inspection Station in Truckee and the wood was found to be carrying egg masses of SLF. The wood was destroyed but this is a significant detection.

We need to communicate with California residents about the danger of moving firewood from place to place within the state and especially across state borders. Firewood can harbor many types of invasive pests include SLF but also invasive shothole borers, gold-spotted oak borers, and other very hard to see invasive insects and diseases.

Jumping worm/crazy worm

The invasive jumping worm (Amynthas agrestis) has many common names: Alabama jumpers, Jersey wrigglers, wood eel, crazy worms, snake worms, Asian jumping worm, and crazy snake worms. The jumping worm has been found in Napa and Sonoma Counties. This invasive worm is similar-looking to the common earthworm but thrashes wildly and is said to jump as much as 1 foot off the ground.

Like other earthworms, jumping worms eat fallen leaves and other natural material on the ground. However, these worms voracious eaters and eat so much of the soil “litter” layer, they eat the tiny natural organisms in this layer almost clearing the top soil layer of all life. Many plants can't grow or spread without the layer of leaf litter plus this disrupts the ecosystem of the leaf litter.

Read more about this worm in this article by Oregon State University. UC IPM is compiling information about the worm and where it has been found in California and will publish and announce this information once finished.

There are many other invasive species we are keeping our eyes out for or are trying to manage the spread around the state. Be sure you, your program's volunteers, and local clientele are subscribed to the UC IPM Home & Garden Pest Newsletter, Pests in the Urban Landscape blog, and social media platforms (@ucipmurban) to ensure you are receiving timely updates and news. UC IPM and the statewide UC Master Gardener program will soon be collaborating on projects to increase our educational tools on invasive pests and how to communicate with the public.

"Trees for Tomorrow Start Today" Master Gardener Program Application for San Bernardino County Residents

Applications Now Being Accepted for the University of California Cooperative Extension Master Gardener Program “Trees for Tomorrow Start Today” Project.

University of California Cooperative Extension (UCCE) San Bernardino County is currently recruiting adults (18 and over) who are interested in becoming volunteers for our "Trees for Tomorrow" project. Complete training is provided online through a 50-hour Master Gardener training class taught by subject matter experts. Master Gardener volunteers will provide research-based information on the selection and care of heat, drought, and pest resistant trees and help our non-profit partners and community leaders enhance tree canopy cover in our most vulnerable neighborhoods. (To date, we are proud to have partnered with the Inland Empire Resource Conservation District, CA Climate Action Fellows and many non-profit organizations, communities, ESRI, and others to give away over 600 trees in the last year!)

Applications to become a UCCE Master Gardener volunteer for this project are open through August 31, 2022. UCCE Master Gardener “Trees for Tomorrow” Volunteer Application link: http://ucanr.edu/u.cfm?id=287

Questions about the application process or the volunteer opportunity? Contact UCCE Area Environmental Horticulturist Janet Hartin at jshartin@ucanr.edu

Why volunteer for this project? We are facing unprecedented times due to climate change and urban heat islands increasing temperatures in our communities. One of the solutions to a "cooler, greener, tomorrow" is through tree planting and proper selection and long-term care of heat, drought, and pest resistant trees.

Why trees? Shade produced by a single tree can reduce surface temperatures of asphalt and other impervious surfaces by up to 65 degrees F. Trees also lower air temperatures; enhance pollinator and wildlife habitat; absorb pollutants; reduce energy use and related costs (homes, offices, vehicles); beautify neighborhoods; absorb and store carbon dioxide; and provide many other ecosystem and societal benefits.

You can make a difference like never before enhancing tree canopy cover in our neighborhoods. Do you want to learn more about what UCCE Master Gardeners do for San Bernardino County residents and communities, find out what upcoming events they are hosting, or have them answer your horticulture questions Here's your pot of gold: https://mgsb.ucanr.edu/

 We are looking forward to hearing from you!

Invasive Beauties Can Be Deceiving

Humans love anything new and different, and that includes plants for their garden. In the past, when bringing plants into California from other places, people had no idea this could cause environmental problems. Whether arriving accidentally or purposely, California has become home for approximately 1,100 plant species/subspecies that did not naturally occur in the state. These plants became naturalized and thrived by out competing California's native flora for water, space, light, and nutrients. Invasive non-native plants crowd out crops, degrade rangeland, increase the potential for wildfire and flooding, consume valuable water, and damage recreational areas. Native plants and animals/insects evolved side-by-side, each benefiting the other. Loss of native plants negatively impacts the indigenous fauna that depend on them for food and shelter, thus reducing overall biodiversity.

The week of Saturday, June 4 – Sunday, June 12 is California Invasive Species Action Week. The goal is to increase awareness of invasive species, their negative impacts, and how you can help stop them from spreading.

What are invasive species?

Invasive species are organisms that are not indigenous, or native, to a particular area. Not all non-native species are invasive. To be considered invasive, an introduced plant species must meet these criteria, established by the EPA:

  • Has few germination requirements, enabling it to adapt to the new environment easily
  • Grows rapidly
  • A prolific seed producer with effective dispersal systems
  • Free of natural enemies and diseases
  • Harms the environment, property, the economy, or the native plants and animals of the region

Plant Invasion in California's Central Valley

Historically, plant invaders significantly altered California's Central Valley landscape to what we know it to be today in a relatively short period of time. The invasion of non-native plants began with the Spanish settling in the state in 1769, likely introduced by plants/seeds on the fur of livestock. The discovery of gold in 1848, produced a flood of people, which accelerated the introduction of non-native plants via contaminants of seed, clothing, equipment, and animals.

Of the invasive species listed on the California Invasive Plant Council Inventory, about 37% were accidentally introduced to the state. The remaining 63%, however, were intentionally introduced for purposes such as landscape ornamentals, soil stabilization, animal forage, human food, fiber, or medicinal.

University of California Integrated Pest Management has a Pest Notes link on invasive plants (http://ipm.ucanr.edu/PMG/PESTNOTES/pn74139.html) which lists the results of UC Master Gardener surveys of invasive plants for sale in California nurseries. Invasive plants rarely or no longer sold are listed.

What Can We Do?

While we cannot bring California back to what it was prior to the arrival of Europeans in the 1700s, we can try to protect what native plant species we have.

Some ways you can help:

  • Educate yourself regarding California's invasive horticultural plants, avoid planting them, and plant their alternatives for your garden.

  • If an invasive plant already exists in your garden, at the very least, the plant should be kept in a vegetative state, so it does not reproduce. If you choose to remove these plants, it is important to make sure reproductive parts do not escape during the removal process.

  • Do not to transport any reproductive parts such as fruit, seed, or root pieces by animal, human or vehicle to areas where plants have not been established. If you go camping or hiking in nature, clean your camping and hiking gear to ensure you are not accidentally spreading hitchhiking invasive species. If you bring a dog(s) along, clean their fur before leaving the park or wilderness area. Stay on designated trails and roads.

  • Encourage local nurseries and garden centers not to sell invasive plants.

  • Join removal efforts. Chances are you can find invasive species volunteer opportunities nearby. Check out your closest state or national park's website to see if they host invasive species walks—many organize half-day or day hikes where you learn to identify and help remove invasive plants.

Becoming a part of ongoing efforts to manage or eradicate the invasive non-native plant species in our state will help reduce their negative impacts on our natural resources. Planting native beauties in your garden is a simple way to help these plants survive and benefit the local fauna food webs.

Reappointment Begins June 1, 2022

It's reappointment time for the UC Master Gardener Program! Before the reappointment process begins we would like to say, volunteers are the heart of the UC Master Gardener Program – thank you! You make the program impact possible. We hope you'll join us for another year of helping gardeners, extending research-based home horticulture, pest management, and sustainable landscape information to Californians.

UC Master Gardener Program volunteers can build on their outstanding work during the 2021-22 program year by reappointing for 2022-23. Annual reappointment is required for all volunteers working with UC Agriculture and Natural Resources (UC ANR).

Please read this update thoroughly and direct any questions regarding the reappointment process to your program coordinator, advisor, or county director. Reappointment takes place from June 1 through July 31. The process for reappointment can be done in 4 easy steps!

Step One: Select "Please Complete!" in VMS

  • Log into VMS, https://vms-mg.ucanr.edu/
  • Select "Please Complete!" under "Reappointment" in right column of your VMS home screen
Reappointment prompts will appear on the VMS home screen of all UC Master Gardener Program volunteers beginning June 1.

Step Two: Click on and electronically sign all three forms

Reappointment prompts will appear on the VMS home screen of all UC Master Gardener Program volunteers beginning June 1. All UC Master Gardener Program volunteers must complete three forms to remain active or limited active for the 2021-22 program year.

Step Three: Verify' Date Completed' column displays the date completed and print a copy for your records

All UC Master Gardener Program Volunteers must complete three forms to remain active or limited active for the 2021-22 program year. Once the forms have been signed in VMS, the 'Date Completed' column will update. Volunteers should print a copy of these forms for their records.

Once you complete reappointment, the reappointment window will no longer appear on your VMS screen.

Step Four: Submit Insurance Fee (if required in your county)

The UC Master Gardener Program requires a $6.00 fee to cover accident and injury insurance. This fee is collected locally by county personnel, paid for by county fundraising, or combined with a county membership fee. All active, limited-active volunteers should contact their local UC Cooperative Extension program coordinator, advisor or county director for more information about local county requirements and, if required, how to submit payment.
