Gall Walk at Little Uvas Open Space Preserve

From the event page: 

Plant galls are beautiful and sometimes bizarre growths on plant tissues induced by another organism, such as a wasp, midge, aphid, mite, or many others. They are surprisingly common, yet grossly overlooked - to the point where dozens of previously undescribed galls are discovered every year, sometimes in people's backyards!

This walk will explore Little Uvas specifically looking for plant galls during the peak of California's "gall season". In fact, this hike is taking place during "Gall Week 2022", a global online event that encourages individuals and organizations to get outdoors to discover and document plant galls on iNaturalist. So bring your smartphone and/or camera, and get ready to learn about an amazing and important part of the food web.
