by Steven Swain Environmental Horticulture Advisor UCCE Marin & Sonoma Counties Integrated pest management, or IPM, is a process you can use to solve pest problems while minimizing risks to people and the environment.
Trees in the red oak section are all either evergreen, have bristles or small prickers on their leaves, or both. Acorns of these species all have scaled cups. Black oak has bristles, but is deciduous.
Trees in the white oak section all have rounded lobe ends, and are all deciduous. They all bear acorns in a single year, and acorns have knobbed cups. Despite the fact that they can all hybridize, the species themselves tend to have markedly different habitat requirements.
Only one oak from this section is found in the north bay, so there is little problem with hybrids confusing identification. The acorn tends to be covered in tiny golden hairs, as are the leaf undersides.
Tanoak (Lithocarpus densiflorus) is not an oak, but a close relative. It has large, leathery leaves with marked parallel lateral veins, and bears acorns that have bristled or spiked caps. It is one of the only acorn bearing trees that is frequently found in redwood forests.
