A free webinar series titled “Trees to the Rescue: Solutions for Climate Change” will be held on May 14-16, from 4 p.m. to 5:30 p.m. each day. The webinars are sponsored by the University of California Thelma Hansen Fund.
“The webinars aim to increase our understanding of the role of trees in mitigating climate change, how to plant the right trees and keep them healthy in urban environments, and the challenges of increasing the number of trees at the local level,” said Annemiek Schilder, director of Hansen Agricultural Research and Extension Center, who is organizing the series. Hansen REC is operated by UC Agriculture and Natural Resources.
The agendas for each 90-minute webinar are listed below. To register, visit https://surveys.ucanr.edu/survey.cfm?surveynumber=42636.

UC ANR held its annual advocacy day on April 10, meeting with state legislators to build awareness of how Californians are benefiting from its work across the state. The group, led by Vice President Glenda Humiston and Associate Vice President Brent Hales, met with Assembly Majority Leader Cecilia Aguiar-Curry, Assembly Agriculture Committee Chair Esmeralda Soria, Assemblymembers Vince Fong and Juan Alanis, and Senators John Laird, Bill Dodd and Anna Caballero.
They also met with the staff of President pro Tempore Mike McGuire, Assembly Speaker Robert Rivas, Senators Monica Limón, Steve Padilla, Roger Niello and Josh Becker, and Assemblymembers Bill Essayli, Cottie Petrie-Norris, Jesse Gabriel, Damon Connolly and Steve Bennett.
This year, Anne Megaro, government and community relations director, and Sheron Violini, associate director government and community relations, added a midday coffee break to showcase UC ANR's wildfire resiliency research and outreachand offer resources for legislative offices to share with their constituents in May, which is Wildfire Preparedness Month. Assemblymember Vince Fong sponsored the room in the Capitol for the briefing. Lenya Quinn-Davidson, Fire Network director, spoke about the importance of prescribed burns and forest management practices and associated job opportunities. Missy Gable, director of UC Master Gardener Program, described how UC ANR is helping communities become more resilient and prepared.
“Our knowledge and prepared outreach materials could be used by offices to help their constituents mitigate wildfire risk,” said Violini. “We garnered great interest from representatives of several caucuses and offices and we are already working with them to share information.”
In meetings with legislators and their staff, the UC ANR representatives shared a one-pager that included the new Luna UCR avocado, reducing food insecurity, and pest management in urban communities as well as on farms.
Humiston and Gabe Youtsey, chief innovation officer, discussed the merits of CropManage, an app used by growers to reduce water and fertilizer inputs while harvesting the same crop yields. The decision-support tool developed by Michael Cahn, UCCE irrigation and water resources advisor, will be showcased at the UC Innovation Fair at the state Capitol on May 8.
Cindy Chen, UC Cooperative Extension woody biomass and forest products advisor in the Central Sierra, and Haris Gilani UCCE biomass and bioenergy advisor in Riverside and San Bernardino counties, described UC ANR's role in ARCHES, California's initiative to accelerate renewable hydrogen projects and the necessary infrastructure. The scientists are identifying ways to use biomass to provide energy and consumer products while creating job opportunities in rural areas.
To continue the learning relationship, they invited the legislators and staff to attend UC ANR events in their respective districts.

General situation
Temperatures remain close to historic normals, and are predicted to remain moderate for the next few weeks. Planting is progressing throughout the Sacramento Valley. I've started to see some early TSWV infections in March-planted fields in Yolo County.
Thrips population
We're heading into the second generation of thrips; egg hatch peaked last week, and adults are predicted to peak May 12th (Fig. 1). 3rd generation adults are predicted to peak in early June, and 4th generation in early July.
In typical years like this is shaping up to be so far, our normal recommendation is that if you don't know of any local sources of TSWV and crops are not in the ground or are just planted it might be worth delaying any treatment until mid-June. It would allow generation 3 adults to breed and lay eggs, but will catch juveniles developing from generation 3 eggs and suppress the spread of any TSWV that has come into crops with generation 3 adults. If you do have local sources of TSWV, or if you've planted early and are worried about early entry of TSWV to your crop, consider treatments in weeks 2 or 3 of May to suppress generation 3 thrips, which could be carrying TSWV.
During this important period for thrips management decisions (Generations 2-4), I'll be posting weekly updates to this blog. Please feel free to contact me (palazicki@ucanr.edu, 530-219-5198) if you have any questions.
