Rough start, but road and paths open

This winter has been a rough one for our campus landscapes. December brought atmospheric rivers and run-of-the-mill storms, saturating the ground. Then, on New Year’s Eve, a bomb cyclone swept through this area, wreaking havoc with its easterly winds (different from the southern winds the trees grew up experiencing), felling most of the 100 trees lost throughout campus and the Arboretum. 

The cleanup effort undertaken by all of the teams in the Arboretum and Public Garden – Grounds and Landscape Services, Putah Creek Riparian Reserve and the Arboretum – is massive, includes outside contractors, and will take months to recover from. Considering our campus urban forest tree population is close to 20,000, the losses might have been much worse. 

Urban Forest Management

While good (and bad) luck always has a hand, there's a lot more than chance involved in the stewardship of such a large landscape.

The Arboretum and Public Garden staff conducts regular tree health assessments, updates the campus's tree database and uses this data to prioritize the type and timing of future maintenance. They support the Campus Tree Renewal program, remove trees in danger of jeopardizing community safety and respond to extreme weather events.

Planning for a Climate-ready Future

While the weather-related havoc wrought across campus is disheartening, it is also important to understand that our campus is not just reacting, we planned for this uncertain future and are already taking action.

As the result of a partnership between the Arboretum and Public Garden and UC Davis Campus Planning, our university has launched an initiative to transition our campus landscapes to be climate-ready. The Living Landscape Adaptation Plan includes strategies to transition our tree canopy, enhance the biodiversity of our landscapes, secure sustainable water sources, support our communities health and well-being, and the best of all, engage our students and community.

Taking Action Now

These recent losses are devastating, but reinforce the importance of our work to select and grow trees that will be resilient in our changing climate. Last academic year, students in the Arboretum and Public Garden's Learning by Leading™ Urban Tree Stewardship program, together with staff and multiple student and community volunteers, planted over 200 trees. This academic year students, staff and volunteers have planted over 250! Other Learning by Leading teams are helping design, maintain or transition campus landscapes to enhance biodiversity and still others are growing climate-ready plants to provide for the community at large, and so much more.

There’s hope ahead!
