Look closely at a patch of California golden poppies and you may see a sweat bee (genus Halictus) collecting gold pollen. The pollen basket is on the hind legs but you'll see "gold" also dusting the head and abdomen.
Native bee, commonly known as "halictid bee." Native plant. In fact, the California golden poppy, Eschscholzia californica, is the state flower.
And the rumor that it's "protected" and you'll get arrested if you pick a poppy along a roadside is inaccurate.
The California Department of Fish and Wildlife sets the record straight on its website: "It is often believed that there are laws prohibiting the cutting or damaging of the California poppy because it is the state flower. While there is no law protecting the California poppy specifically, California Penal Code Section 384a(opens in new tab) requires written landowner permission to remove and sell plant material from land that a person does not own, and removing or damaging plants from property that a person does not own without permission may constitute trespass and/or petty theft. However, these laws do not prevent the collection of California poppies on private land by the landowner. California poppies are a beautiful and easy-to-grow addition to your garden, and although you may choose to pick them from your property, they last much longer in the ground!"
Want to learn more about native bees? California has some 1600 species of wild or non-managed bees. Be sure to read California Bees & Blooms: A Guide for Gardeners and Naturalists. It's the work of University of California authors, all with UC Berkeley connections: Gordon Frankie, now professor emeritus, UC Berkeley; Robbin Thorp (1933-2019), UC Davis distinguished emeritus professor who received his doctorate in entomology from UC Berkeley; photographer Rollin Coville, who holds a doctorate in entomology from UC Berkeley, and Barbara Ertter, curator at the UC Berkeley-based University Herbarium and Jepson Herbarium.
The Bohart Museum of Entomology is hosting an open house on bees, both wild and managed, from 1 to 4 p.m., Sunday, May 19 in Room 1124, Academic Surge Building, 455 Crocker Lane. It's free and family free.

She's right at home with a "Oh, my drawers" of insect specimens, and the live critters in the petting zoo--the Madagascar hissing cockroaches, stick insects, tarantulas and more...She's eager to communicate science and draw interest in insects.
On April 29, Tabatha Yang was at UC Davis Chancellor Gary May's residence to accept the Chancellor's Outstanding Staff Award for Exceptional University Management and Exceptional University Impact with 11 other outstanding staff.
UC Davis distinguished professor emerita Lynn Kimsey, the 34-year director of the Bohart until her retirement on Feb. 1, accompanied her.
Sandy Batchelor, Human Resources WorkLife manager and awards committee chair, earlier said that Yang embodies "the spirit of engagement, innovation, and inclusivity that defines the university. With 15 years of dedicated service at the Bohart Museum, Tabatha spearheads a variety of educational initiatives aimed at demystifying and highlighting insects, spiders, science, and higher education."
"Through open houses, classroom visits, fairs, festivals, and other outreach programs, she helps the museum connect with more than 10,000 people each year. Under her leadership, museum walk-ins, tours and tabling events provide opportunities for students, staff and faculty to engage in science communication, highlight research and connect with others."
Yang annually chairs the committee that hosts UC Davis Biodiversity Museum Day, a “Super Science Day” that showcases 10 to 12 museums or collections and highlights UC Davis' research, collections and biodiversity, drawing thousands to campus.
She is also the founder and director of Bio Boot Camps, an immersive experience that ignites passion and curiosity in teenagers from around the globe. These camps, held annually since 2011, except during COVID, offer a gateway to the wonders of ecology, scientific exploration, and campus life. Campers tour UC Davis and its museums and collections and embark on scientific explorations of the UC Davis Putah Creek Riparian Reserve, Quail Ridge Field Station, Bodega Marine Laboratory and Bodega Marine Reserve and UC Berkeley's Sagehen Creek Field Station. With needs-based scholarships, Tabatha ensures inclusivity, making dreams a reality for aspiring young scientists.
Tabatha, a Cornell University alumna, shares her science educational background with her husband, community ecologist and professor Louie Yang, a Cornell alumnus who received his doctorate from UC Davis. He joined the UC Davis entomology faculty in 2009.

I've spoken with countless gardeners over the years who wish to start their own bee haven. That's great -- the bees need all the help we can give them. But the most misunderstood part of the process is how much preparation needs to take place before a single plant goes in the ground.
As the Haven winds down, I'd like to share some tips on preparing to install your own bee garden.
Many gardeners are removing a turf lawn to create their bee haven. It's important to take the time to do this correctly so your garden doesn't revert to a weedy mess. UC IPM has great information about turf removal, including how to identify your turf species (knowing your species helps with removal) and how to remove existing turf.
If you are opposed to using herbicides to kill your lawn, solarization can also be used. For most lawns it will take longer and be less effective. That is definitely the case for bermudagrass lawns that are common in California. Figure 1 summarizes the pros and cons of various turf removal methods. For more own bermudagrass lawn, I used a combination of herbicides, sheet mulching, and hand removal.
Finally, weed barrier fabric is never recommended. It prevents ground-nesting bees from accessing the soil, traps weed seeds that grow through the fabric and become impossible to remove, and breaks down over time to leach microplastics into the ground.
Whatever methods you use, patience is key. Plan on at least one year of preparation before planting.
It's also essential to know your soil type and its physical characteristics. Jar tests and drainage tests provide important information about how your soil will hold water. In California, the UC Davis Soil Web has detailed soil maps; these may be less accurate if you are in a new development where there has been recent soil disturbance or addition of new topsoil.
Finally, watch the pattern of sun and shade in your garden for a year before planting. Many winter-blooming 'full sun' plants will do fine under deciduous trees as they are in full sun when flower buds are forming. In the hotter part of California, some 'full sun' plants may need shade in afternoon.
The final task while you're in the process of killing your lawn is to learn about and choose plants for your garden. Garden tours are a great way to start this process....you'll see what grows in your area and have the chance to speak to other gardeners. These are often sponsored by municipal water authorities. Botanic gardens and independent garden centers with knowledgeable staff are other great resources.
The UC Master Gardener program has trained volunteers throughout the state to provide research-based gardening information. They are a fantastic resource and hold educational programs like this one for the public. Finally, garden clubs and the California Native Plant Society hold tours, plant sales, and educational events.

Honeybee Discovery Center, Nicole Johansson
The Honeybee Discovery Center, currently located at 501 Walker St., Orland., Glenn County, Calif., is designed to teach the public about honey bees and the rich history of beekeeping in Northern California, according to its website. "The Center is a place for the public and schools to learn about honeybees and for the beekeeping community to display items that are part of beekeeping and its history."
Northern California is known for its queen bee rearing, with tens of thousands of queen bees produced annually. Orland is considered the “Queen Bee Capital of North America.” Eighty percent of the queen bees raised in the United States are from Butte, Glenn, Shasta, and Tehama counties, "The Golden Triangle.” Orland is also the 40th “Bee City, USA” with a commitment to creating greater awareness and an environment that protects honey bees and other pollinators. Yvonne Koehnen of the C. F. Koehnen & Sons Inc., originated the idea of the Honeybee Discovery Center. The Center, which includes a museum, is open the first consecutive Friday and Saturday of every month from 3 to 6 p.m.

The best time to plant a tree was 20 years ago. The second-best time is now.
– Chinese Proverb
What is your happiest memory that involves trees? Hopefully, most of those memories are positive. Trees provide a multitude of benefits that are hard to overlook. Reflecting on happy memories involving trees often evokes a sense of joy and wonder. These towering guardians not only serve as the backdrop to cherished moments but also provide an array of invaluable benefits.
However, in regions like the Western United States, escalating wildfire risks loom large, burdening homeowners with soaring insurance costs and stringent fuel reduction mandates. Balancing the delicate interface between natural landscapes and urban expansion becomes increasingly intricate, especially when community priorities diverge. As residential areas extend into undeveloped territories, trees, whether vibrant or ailing, transition from assets to potential hazards, underscoring humanity's profound dependence on their presence despite the associated challenges.
Trees are essential components of our daily lives, providing a multitude of human health benefits that we often take for granted. Regardless of whether they thrive in lush forests or line bustling urban boulevards, trees also offer a plethora of environmental advantages. Currently, forest ecosystems are the largest land-based carbon sink on earth. Forests in the U.S. alone offset about 16 percent of annual greenhouse gas emissions. Ninety percent of Americans support tree planting as a climate change mitigation measure.
Trees are also an essential component to ecological systems. They produce oxygen, sequester carbon, lower surface temperatures, control erosion, mitigate stormwater runoff, enhance habitat and biodiversity, contribute to urban cooling, provide food and fiber, promote social-emotional well-being, and perhaps most importantly, provide beauty to the landscape. Trees also boost property values and can even attract shoppers to urban centers.
Amidst a global population surge and escalating food demands, rampant deforestation threatens nearly half of our planet's forests. This perilous trend undermines crucial opportunities for carbon sequestration, allowing emissions from vehicles, industries, and other sources to persist unchecked. Moreover, the absence of verdant canopies in urban landscapes exacerbates the formation of heat islands, posing serious public health risks.
Deciding what tree to plant where can be challenge for some. Some (native) trees are not adapted to urban environments, while others may drop leaves, flowers, fruit, or branches, push up sidewalks, require frequent pruning, become invasive or have other undesirable characteristics. Municipal tree maintenance programs are costly and even controversial in some communities.
The Urban Forest Ecosystems Institute at Cal Poly is a tree information site with "features to assist in narrowing down site conditions, watering needs, and phenological characteristics. The “Select a Tree" feature assists users in choosing a tree with desired characteristics suited to a particular location.
I personally cannot imagine a life without them. As stewards of the environment, it's imperative that we recognize the indispensable role trees play in sustaining life and take concerted action to protect and nurture them for generations to come.
