Steve Tjosvold, UCCE environmental horticulture advisor, retires after 38 years
“I interned for two advisors and then separately filled in for the programs of two advisors that went on sabbatical leave,” Tjosvold said. “I use that experience, knowledge, contacts and friendships to this day.”
Tjosvold was named the environmental horticulture advisor in Santa Cruz and Monterey counties in 1983.
Tjosvold's early career focused on the management of nursery and landscape plant diseases and insect problems, as well as methods to improve water use and postharvest handling in nursery crops. In addition, Tjosvold helped establish the use of scouting in ornamental production by working with other farm advisors to document effectiveness statewide. Later, his research and outreach on sudden oak death and light brown apple moth helped growers understand the pests and take action to reduce their impact on production systems and the environment.
Tjosvold wrote or contributed to 94 peer-reviewed publications and 234 industry publications. He served as editor/co-editor of UCNFA (UC Nursery and Floriculture Alliance) News.
During his career, Tjosvold received three distinguished service awards for outstanding teamwork (1997, 2004, and 2006) and one for outstanding extension (2004). He received the 2008 Western Extension Directors' Award of Excellence for a farm water quality planning project. In 2012 he received the outstanding research award from the California Association of Nurseries and Garden Centers, and in 2015 he was honored with the Award of Excellence from the Western Extension Directors Association for a team effort that addresses Sudden Oak Death.
In retirement, Tjosvold plans to start a UCNFA blog to help replace the loss of the UCNFA newsletter due to retirements. He will also be available locally for focused educational projects and consultation. Tjosvold, an avid fly fisherman, said he will spend the first month of his retirement camping and fly fishing in Montana.
