A Message from Dean Helene Dillard: Pollinators and honey bees get well-deserved attention

deanThe federal government recently announced a far-reaching plan to promote the health of honey bees and other pollinators. It has three primary goals: dramatically reduce honey bee colony losses, increase the population of monarch butterflies, and increase pollinator habitat acreage by 7 million acres. This is welcome news for an issue that we are well aware of here in California, with our state’s heavy dependence on honey bees and pollinators to sustain production of many of our fruits, nuts, and vegetables.

UC Davis has long been a world leader in research, extension, and education in the realm of honey bees and native pollinators. As Michael Parrella, chair of the Department of Entomology and Nematology, told the “Keeping Bees Healthy” symposium on May 9, “We’ve been doing honey bee research way before it became popular.”

Our programs in this field go back decades. Harry Laidlaw, a pioneer in honey bee genetics, led campus efforts to build what is to this day the largest stand-alone bee research facility in the United States. Other scientists such as Norm Gary, Robbin Thorp, Christine Peng, Robert Page, and Eric Mussen have kept UC Davis at the forefront of work on honey bees and native pollinators.

Today, a new generation of researchers and educators has picked up the mantle. Within the last year we hired Elina Niño as a Cooperative Extension specialist to continue the outstanding program that Eric Mussen built. Her honey bee laboratory is dedicated to supporting the state’s beekeepers through a program of basic and applied research and sharing information through extension and outreach. She advised the 360 beekeepers and others attending the symposium on best management practices to support honey bee health. Colony losses nationally have been as high as 40 percent in recent years, caused by multiple stressors such as diseases and parasites, exposure to pesticides, and lack of sufficient nutrition. Niño says beekeepers are trying to keep track of what’s going on in their colonies and are implementing integrated pest management strategies.

Honey bees and native pollinators need diverse pollen sources and that is where the work of entomology professor Neal Williams comes in. Part of his research focuses on the interplay between these two groups and figuring out ways to help both. Williams says the irony of intensive agriculture is that’s where the need is greatest, yet “clean” farming practices have removed a lot of vegetation that could help sustain pollinators. An emerging strategy he is studying is to enhance floral diversity through the use of pollinator meadows and wildflower strips planted adjacent to row crop agriculture. The twin goals of this work are to support forage habitat for honey bee and wild bee populations and to enhance pollination services to crops within agricultural landscapes. He and colleagues have developed recommended mixes of drought tolerant California native plants that can do the job.

And then there’s our Häagen-Dazs Honey Bee Haven, managed by Christine Casey. If you haven’t visited this educational oasis west of campus, plan a visit. Built with the support of the ice cream maker and others, it is located next to the Harry H. Laidlaw, Jr. Honey Bee Research Facility on Bee Biology Road and is open year-round. The garden has 260 different plant species that provide forage for bees and pollinators. Its primary mission is to educate and inspire urban gardeners about bees and pollinator-friendly plant selections. The garden design was based on a competition. It attracts hundreds of people every year, including K-12 schoolchildren, youth groups, and UC Davis students participating in classes and internships. You can keep on top of developments at Häagen-Dazs Honey Bee Haven on its Facebook page.

There’s much more going on at UC Davis in the world of bees and pollinators and we in the college remain committed to supporting this vital area of research, education, and outreach. Pollination services provided by honey bees and native pollinators are worth billions of dollars annually and help ensure our abundant and diverse food supply. We all have an interest in the well-being of these wild and managed insects and the work they do. I think about that every time I walk down the produce aisle.

Melissa Whaley and Ed DePeters selected for Eleanor and Harry Walker Advising Awards


Celebration of Advising Excellence – Staff adviser Melissa Whaley and Professor Ed DePeters received the Eleanor and Harry Walker Advising Award at a campus reception May 26. In photo from left to right are Dean Helene Dillard, Associate Dean Sue Ebeler, Eleanor Walker (seated), Melissa Whaley, Ed DePeters, and the Walkers’ daughter, Laurie Walker-Whiteland.

Environmental science and policy staff adviser Melissa Whaley and professor Ed DePeters are the 2015 recipients of the Eleanor and Harry Walker Advising Award. They were honored at a campus reception May 26.


The award supports and recognizes excellence in advising in the College of Agricultural and Environmental Sciences. Although the staff award has been given for many years, this is the first year the award has also been given to a faculty adviser. Whaley is the staff adviser in the environmental policy analysis and planning (EPAP) major, and is co-adviser for the environmental science and management (ESM) major.

Whaley is known for being proactive in reaching and retaining students and works hard to increase connections between faculty advisers in her department and current students and alumni. She coordinates an annual career event for ESM majors that provides opportunities for students to meet with alumni and student-selected professionals.

DePeters is a professor in animal science and serves as the master adviser for the animal science major. Students cite his positive influence on their lives. He developed an annual advising training program for faculty advisers and guides new faculty in developing their advising skills. He also manages the Animal Science Advising Center.

The late Harry O. Walker was a professor in the Department of Land, Air, and Water Resources for more than 40 years. He was a strong supporter of advising and served as a master adviser for undergraduate students. Walker once said, “One of my areas of interest is natural resources, and young people with active minds are our most important ‘natural resources.’ We as a community have an opportunity, as well as a responsibility, to maximize the capabilities of these individuals.”

Campus updates online events calendar

UC Davis has a new and improved online calendar. The calendar, developed by the Office of Strategic Communications, launched in May.

The calendar is designed to be the most complete listing of what’s happening at UC Davis — from seminars and conferences, and arts and athletic events, to fairs, expos, and exhibits. The calendar includes images and logos, map links (for venues), search and filter tools, and “Add to calendar” and “Forward to friends” buttons. Open an event and more options, such as email and text reminders, are available. Event planners can use it as a registration tool. Every event includes sharing tools for social media. Users can subscribe to automatic feeds for all events that fit personal criteria.

The Trumba-based calendar system can be customized. A department, for example, can gather all of its events from the main calendar, and embed them as a calendar on a department website. This way, department personnel are inputting each event only once and displaying it in multiple locations.

The calendar will eventually be open to all UC Davis departments and units. Departments and units will enter their own events, which are then routed to designated calendar administrators in the colleges, schools, and administrative units for approval and posting.

Visit the new online calendar. To learn more, read this article from Strategic Communications.
