LOS ANGELES CO., Calif. — Don Hodel, University of California Cooperative Extension environmental horticulture advisor for Los Angeles County, will retire July 1 after more than three and a half decades.
“He is a valuable resource in Southern California and has provided me with assistance on many occasions,” said Jan C. Scow, a registered consulting arborist based in Santa Monica. “Most valuable, and where I have turned to him most frequently for his expertise, is his global knowledge of palm trees.”
Hodel, best known for his remarkable and encyclopedic work in palms, is an internationally recognized leader in the environmental horticulture world. His research focuses on the selection, planting and management of woody plants in the landscape. He has published nine books, 100 peer-reviewed articles and 522 technical and popular articles. In addition, he delivered more than 1,000 presentations for industry groups, professional societies, universities, government agencies and homeowners and gave interviews to various news media organizations.
Hodel’s body of work contributed significantly to the California landscape industry. He introduced and promoted new woody plant material suitable for California’s climate. He developed landscape plant management techniques and practices that reduce green waste stream, support sustainability and help residents save money. He also advocated irrigation practices that help save water and management techniques that reduce damage to plants by landscape pests and diseases.
In 2014, Hodel produced and co-presented a day-long seminar in Spanish for Spanish-speaking tree workers on palm biology and working safely while managing palms. “It was immensely rewarding interacting with these workers, especially seeing them grasp the knowledge and techniques that will help keep them safe,” Hodel said.
“Don has been a teacher, a selfless resource of valuable information, a colleague and a friend,” arborist Scow said, adding, “Don has provided a valuable and welcome boost to many in the arboricultural profession and has ‘done the UC proud!’”
Over the years, Hodel has received numerous prestigious awards including UC ANR’s Award for Research (1993), Western Chapter International Society of Arboriculture Award of Arboricultural Research (2009), and Southern California Horticulture Association’s Horticulturist of the Year (2014).
“I have been honored and privileged to have worked for the University of California for 36 years doing what I love—researching, writing and sharing information with homeowners and the landscape industry,” Hodel said. “I am very thankful to UC for providing me with a platform to accomplish my work.”
Hodel received his bachelor’s degree in ornamental horticulture from the California State Polytechnic University in Pomona and his master’s degree in tropical horticulture from the University of Hawaii in Honolulu. Prior to joining UC, he worked in the industry for eight years in Hawaii and California.“We will miss him very much,” said Keith Nathaniel, UC Cooperative Extension director for Los Angeles County. “His work has contributed tremendously to UC Cooperative Extension and its mission of addressing local issues with innovative solutions through the power of UC research. It will be difficult to replace his high-caliber knowledge and expertise.”
During retirement, Hodel plans to remain active and continue his support of the university with his emeritus status. Along with completing his current research projects, he plans to finish writing three books. One is about the palms of Cuba, based on his three research trips to the island-nation from 2016 to 2018. The second is a guide to identify and manage ornamental Ficus (figs) in California and Hawaii. The third is a compendium of dryland trees suitable for the Southern California landscape.
“I have a lot of information in my head that I want to share before it is too late!” said Hodel.
