An outdoor living museum located on 3,500 acres, Holden Forests and Gardens that promotes “the beauty and importance of trees and other woody plants.” Today and tomorrow from 10 a.m. to 4 p.m., the arboretum will host Celebration of Trees, a weekend event with family-friendly activities centered around trees and their vital role in our community. There will be guided tree climbing for children, chainsaw carving demonstrations and a Great Lakes Timber Show that stresses the importance of lumberjacks for forest and tree management through selective harvesting.

Award-winning chainsaw artists Pat Holbert, owner of Sugar Ridge Carving, and partner Jack Riese, will be on hand. Food and beverage concessions will be available for purchase. Admission to the event is free for members, $10 for nonmember adults and $4 for children ages 6-18. Children age 5 and under are admitted free. The Murch Canopy Walk and Kalberer Emergent Tower will be open during the event. Tickets to those attractions are free for members, $4 for nonmember adults and $2 for children ages 6 to 18. (Niesel)
