Poison Oak is abundant. It can be low and meandering and it can vine and climb. The oil, Urushiol, causes a miserable dermatitis in about 75% of people. It’s particularly potent in spring when the leaves are shiny and when it’s producing berries. Goats will happily eat it but only after the berry phase, when the leaves are less shiny. Interest wanes when the leaves die back, change color, and get crispy in the fall. If you’ve got a lot of Poison Oak, consider hiring for July-August.
