Improvements to Arboretum Waterway
A recently-completed engineering project is circulating nearly two million gallons of recycled water per day through the west end of the Arboretum Waterway, to improve water quality and aesthetics. Campus engineers adapted an existing, abandoned pipeline to run treated water from the campus wastewater treatment plant through the Arboretum Waterway before it is discharged into Putah Creek. The resulting circulation is expected to reduce the rapid algae growth that often turns the water green in summer.
Oak Collection Honored
The UC Davis Arboretum oak collection has recently been accepted for membership in the North American Plant Collections Consortium, a program of the American Public Gardens Association, in cooperation with USDA and the U.S. National Arboretum. Participating institutions commit to professional standards of collections management and make germplasm available for selection and breeding, taxonomic studies, evaluation, and other research purposes.

Managing the Egret Colony at Shields Oak Grove
The Arboretum is working with campus wildlife biologists to track the rapidly-expanding colony of egrets and herons nesting in Shields Oak Grove, our most scientifically-significant collection. The number of nests of cattle egrets, a prolific, non-native species, increased from 87 in 2005 to 495 in 2007. The birds’ excrement, or guano, threatens the health of the trees by changing the chemistry of the soil and coating leaves so they can’t photosynthesize. Researchers are experimenting with humane methods of discouraging nesting, such as removing the remnants of last year’s nests and shining a bright light at the birds.

UC Davis Arboretum GATEways Project
The UC Davis Arboretum GATEways Project (Gardens, Arts, and The Environment) is a master planning framework that envisions the Arboretum landscape as a welcoming entry to campus for the public and a multi-layered learning experience, where visitors can discover the rich creative and scholarly work of UC Davis.
