National Invasive Species Awareness week: February 27 – March 3, 2017
—Stephanie Parreira, UC Statewide IPM Program
In agricultural systems, invasive species may reduce yields, render crops unmarketable, or make rangeland unfavorable to livestock. In natural areas, they may squeeze out native species, change soil quality, and increase the frequency or intensity of wildfires.
Some of these species have been introduced intentionally (e.g., yellow sweetclover, which was originally imported from Europe as a forage species for livestock), while others arrived by accident (e.g., the glassy-winged sharpshooter which came to California inadvertently through nursery stock shipments).
Just one species can be detrimental to crop production and revenues. The invasion of spotted-wing drosophila, for example, caused conventional raspberry growers in California to lose $36.4 million in revenue between 2009 and 2014, and would have reduced California raspberry yields by as much as 50% without control efforts.
The spread of invasive pests has become more prevalent in recent decades, and is linked to several factors, including global travel, produce trade, and climate change. Many invasive pests spread by human movement—medusahead, for example, has long awns on its seeds that easily attach to clothing and animal fur, to be carried to other locations. A recent study by UC scientists also determined that due to climate change, invasive weeds are shifting their ranges at a faster rate than native plants, and will likely cause more problems in agriculture and natural resources in the future. The yellow starthistle, an invasive plant that dries out soil and degrades rangelands, is one of the pests that will expand its range further north in California (and beyond) due to climate change.
While invasive pests can be a major challenge to growers and land managers, there are successful stories of stopping exotic pest invasions with well-coordinated eradication efforts. Recently, the California Department of Food and Agriculture (CDFA) declared the European Grapevine Moth eradicated from California after no moths were found in the state from 2015 to 2016. This was due to a rapid response, largely by the UC Cooperative Extension scientists after the moth was discovered in Napa vineyards in 2008.
Here's what you can do to keep from introducing or spreading invasive species:
- Fully cooperate with agricultural inspections at the California state border and in your fields. When coming into California from another state, declare any plant or animal material that you have in your vehicle. Inspectors will thoroughly examine your materials or crops to make sure that they do not hold any invasive pests. This greatly reduces the chance that your activities will spread harmful invasive species.
- Check and clean your clothes, shoes, and equipment before you move from one location to another. For example, thoroughly cleaning your shoes with water and a disinfectant after hiking through an area known to have sudden oak death will prevent you from tracking the pathogen into uncontaminated areas. Similarly, checking your clothes or shoes for weed seeds before leaving an area will keep you from spreading invasive weeds.
- “Burn it where you buy it.” Burn firewood in the same place you purchased it, rather than buying it and transporting it elsewhere. If you must transport firewood, be sure to declare it at the border and have it inspected, as described above.
- Report invasive pests in your area. CDFA has a tool for reporting pests, but you can also contact your agricultural commissioner or UC Cooperative Extension to do so.
To learn more about invasive species, visit the UC IPM website. You will find a list of invasive insects, plants, diseases, and vertebrates in California, as well as links to other organizations and regulatory agencies that are also working to reduce their numbers.

We are in the midst of a new and changing era of Worker Protection Standards (WPS). The U.S. Environmental Protection Agency (EPA) and the California Department of Pesticide Regulation (DPR) recently published the revised WPS, which is meant to increase protections for agricultural fieldworkers and pesticide handlers from pesticide exposure when they're working in farms, forests, nurseries and greenhouses. The changes are already affecting California agriculture!
What major regulatory changes have already gone into effect?
Several changes are required to have been in place as of January 2, 2017. These include:
- All 417,000 fieldworkers in California must attend annual pesticide safety training.
- Records of all fieldworker pesticide safety trainings must be kept on file for 2 years.
- Fields must be posted when the restricted entry interval (REI) exceeds 48 hours.
- “Application-exclusion zones” must be implemented to prevent the entry of anyone into areas up to 100 feet from pesticide application equipment.
- Instructors previously qualified via a DPR-approved Instructor Training programs (Train the Trainer) are qualified to train through 2017. If you wish to be qualified to train fieldworkers and handlers after December 31, 2017 using this qualification, you must complete an updated, DPR-approved Train the Trainer workshop.
Now is the time to make sure these changes are put in place!
What major regulatory changes are still in store for us? When will they happen?
The regulatory changes that must be in place by January 2, 2018 include:
- Additional training topics for fieldworkers and handlers have to be added to the curriculum.
- Handlers have to suspend an application if anyone enters the application exclusion zone.
Who do these changes affect?
Many people who work in the California agricultural community will be impacted by the WPS revisions. These include fieldworkers, pesticide handlers, farm labor contractors, private and in-house safety trainers, growers, farm managers, licensed pesticide applicators (private and commercial), pest control advisors (PCAs), and crop consultants, to name a few.
How do I know if I am qualified to train?
If you attended one of the DPR-approved Train-the-Trainer programs you are qualified through 2017. However, if you wish to continue training after the end of the year, you must complete a DPR-approved Instructor Training Program, which includes the 2018 training topic requirements.
If you maintain certain licenses/government designations, including PAC, QAC, QAL, PCA, and certain County Biologist licenses you are qualified to train. UCCE Advisors are also qualified to train.
How can I get qualified as a trainer?
To become a trainer, take an Instructor Training program that is approved by DPR for 2018 topics. The University of California Pesticide Safety Education Program (part of the UC Statewide Integrated Pest Management Program, UC IPM), in partnership with AgSafe, will offer multiple workshops this spring that cover the new federal requirements for fieldworker and handler training. You can reserve your spot now. At the end of the training you will be a certified pesticide safety instructor.
If I am currently qualified, how can I make sure I stay up to date on all the new requirements?
If you are currently qualified as a trainer because you maintain a California PAC, QAC, or QAL, or if you are a PCA, you can attend an Instructor Training Program this spring to learn about the new WPS requirements and additional training topics. While a certification may qualify you, an Instructor Training Program will prepare you to train! Register today!

Join us for FIT+ (Forestry Institute for Teachers PLUS), a two-day workshop that provides training in K-12 environmental educationand special access to guest experts and unique California sites. All participants receive Project WET certification and a FREE K-12 curriculum guide. In addition to water and forestry topics, locally relevant topics may include watershed conservation, fire ecology, urban forestry and more! The training is designed for formal and non-formal educators who work with youth.
With the passage of the Every Student Succeeds Act (ESSA), the recent publication of California's Blueprint for Environmental Literacy, and the impending implementation of Next Generation Science Standards, Project WET is a valuable resource for bringing environmental education into the classroom and for bringing students outside. The award-winning curriculum guide, recommended by NSTA, provides flexible and interdisciplinary activities for all K-12 grade levels and subject areas, supporting current and emerging learning standards. Project WET makes a great addition to any educator's toolkit!
FIT+ sessions are coming up in October (Yuba County), November (San Luis Obispo County), and January (Orange County). Scroll down to view the flyer or open the attached PDF and register at www.forestryinstitute.org/education.
