Rydell National Wildlife Refuge in Polk County will be celebrating its 20th anniversary Sunday with an open house at the refuge visitor center.

The event, which also includes a “Rydell Refuge reunion,” begins at 1:30 p.m. Activities on tap include a presentation and demonstration on monarch butterfly tagging, bug catching, button making, face painting, paw printing, a pollinators’ “larger than life” bubble, a wildlife calls exhibit and wagon rides around the refuge.

If you’ve never been to Rydell, Sunday’s open house offers the perfect excuse. There’s also a seven-mile system, five of which are paved.

In conjunction with Sunday’s open house, the Friends of Rydell Refuge Association is hosting a reunion at noon for past and present members of the group. The open house follows at 1:30 and continues until 4 p.m. Refreshments will be served.
