Phytosphere Research - Horticulture / Urban Forestry / Plant Resources / Agriculture

About Phytosphere Research


Located in Vacaville, California, Phytosphere Research was founded in 1987 to provide contract research and consulting services related to natural resource management, horticulture, urban forestry, and agriculture.  Our services are available to public agencies, businesses, and individuals. We have built our reputation and practice on high quality service tailored to meet the specific project needs of each client. We emphasize close communication with our clients to ensure that any project we undertake meets their needs completely.

Phytosphere Research specializes in practical or "mission-oriented" research projects.  Our goal is to provide sound information that will allow our clients to make informed resource management decisions.  Phytosphere Research has completed a variety of research projects related to urban forestry and the ecology of oak woodlands and other California plant communities.  In addition, the research backgrounds of the two principals include experience with many diverse projects, including biological control of aquatic weeds, studies of air pollutant effects on plants, agricultural pesticide evaluation, development of disease-resistant vegetable varieties, and assessment of factors affecting root diseases.

In addition to research, Phytosphere Research provides natural resource and horticultural consulting services.  This consulting experience complements our research activities by keeping us involved with practical, day-to-day issues in resource management, urban forestry, and horticulture.
