The Gall(s) of WA: WNPS meeting

Education, Community Event, Green/Environmental

Ron Russo, retired Chief Naturalist for the East Bay Regional Park District in the San Francisco Bay Area, will explore with us the relationship between numerous native plants and a few local ornamentals by a variety of invading organisms that induce swellings or plant tumors called galls. Galls are generally of a specific size, shape and color, which happen to be specific to the inducing organism.
