Special Discover Galls Hike at Edgewood Park and Natural Preserve

Galls are an often overlooked part of nature. Many insects cause plant galls but they can also be caused by other organisms. Some of the most interesting and beautiful galls are caused by a family of wasps, the gall wasps. Many of these galls are found on oaks and Edgewood is a great place to discover their strange and wonderful forms. Join Friends of Edgewood docent Caroline Bowker and gall expert Aaron Shusteff on this special gall discovery hike that will open your eyes to something you may have never known existed. It is also a great way to participate in iNaturalist's 2025 Gall Week!

This hike starts from the Clarkia Trailhead on Cañada Rd. at Edgewood Park and Natural Preserve.

Wear sturdy shoes and bring water. Consider sunscreen, a hat, and snacks. There are no restrooms or water available at this trailhead. Please plan ahead.

All participants, including children, must be registered individually and have approved the liability waiver through Eventbrite. Details on where to meet will be emailed to participants before the event.

We will still hike in light showers, but heavy rain cancels this hike.

Group size is very limited. Please cancel your reservation if you are unable to attend so others may have a chance to join us.

We ask folks to register for our hikes in order to keep group sizes manageable, but often we have a few no shows. If you’d like to take a chance, you are welcome to drop-in 10 minutes before the beginning of the hike to see if there is extra room. Unfortunately, we cannot confirm whether there will be space for drop-in hikers in advance. Thank you for your understanding.
