Environmental Horticulture: Landscape Construction and Maintenance Certificate Agriculture & Natural Resources Total Units: 22
Term Effective: Fall 2024


The Environmental Horticulture: Landscape Construction and Maintenance Certificate of Achievement program deals with all aspects of plant use and site enhancements in the landscape. This is the most advanced level certificate in the Landscaping program.

People working in the landscape field derive job satisfaction from enhancing the function and beauty of the environment while being physically active outdoors or helping support that activity in allied sales and service occupations. Landscape work involves construction and planting projects, irrigation system design and water management, and specialty fields such as turf management, tree care, and interiorscapes. This program provides an introductory base of plant knowledge and landscape skills, allowing students the option of entering a variety of jobs with the preparation for rapid advancement within their chosen occupations. The program emphasizes hands-on learning and most courses incorporate lab activities that apply knowledge and skills in realistic settings. The program is actively supported by the local horticulture industry.

The Horticulture industry, which involves the growing, selling, planting and servicing of plants and landscapes for human environments, is one of the fastest growing industries in America. The landscape industry in California is one of the state's largest industries. University studies have consistently found this dynamic, growing sector represents over $12 billion in sales and 130,000 employees. In addition, designed and maintained landscapes cover more than 1.6 million acres in California.

In Sonoma County the landscape industry has expanded dramatically in the last decade. Private and commercial property values are enhanced by professionally installed landscapes, and the services of large and small landscape firms are in high demand. In addition, a significant number of independent, entrepreneurial landscape/garden designers offer services throughout the county.

This industry-wide expansion has been accompanied by an increase in the demand for employees who can deal with all aspects of the landscape. Men and women who possess landscape management skills are qualified to advance into supervisory and management positions within landscape contracting firms, design or landscape construction companies, municipal, state, county, and federal agencies, entrepreneurial landscape maintenance enterprises, and other occupations that require the application of plant knowledge, drafting/design, irrigation design, and landscape construction skills.

This program of study is also available as an Associate degree major option.
