Environmental Horticulture & Urban Forestry, Bachelor of Science College of Agricultural & Environmental Sciences

As of Fall 2022, the Environmental Horticulture & Urban Forestry major is no longer accepting new students. It has been absorbed into the Plant Sciences major as an area of specialization.

The Major Program

Students majoring in Environmental Horticulture & Urban Forestry learn how plants improve the environment and the quality of our lives. The major focuses on the biological and physical concepts and horticultural principles of plant production, management of plants and plant ecosystems in landscape settings and sociological aspects of plant/people interactions in the urban environment. Plants are used to revegetate and restore disturbed  landscapes, control erosion and reduce energy and water consumption. The ornamental use of plants to improve the aesthetic quality of urban and rural landscapes, recreational areas, interiorscapes and commercial sites is an important aspect of this major. Students may select one or more of the following three areas of specialization: Floriculture/Nursery, Plant Biodiversity/Restoration, or Urban Landscape Management.

Internships & Career Opportunities

Students are encouraged to develop internships on or off campus to augment their activities in the classroom and laboratory. Internships are available with the department's greenhouse facility, the UC Davis Arboretum, landscape designers, local nurseries, government agencies, regional non-profits, and restoration firms. Career opportunities in this field include growing and/or managing plants in a variety of settings, including nurseries & arboreta, consulting as an arborist, or as an urban, landscape, or restoration horticulturist; business ownership; park management and landscape contracting; working in the public or private sector, or for non-profit organizations.

Major Advisor

Advising Center for the major is located in 1220 Plant & Environmental Sciences; plsadvising@ucdavis.edu.
