A change in the Nature Walk schedule: the Lichen Walk with Margaret Symon will be on Sunday July 29 at 1 p.m. (rather than Sunday July 22) This is a popular outing suitable for all ages.
A couple of interesting facts about lichens: Did you know that the height of the lichens on the tree trunks can be considered an indicator of the average snow depth in the winter? Also, lichens are sensitive to air pollution, so an abundance of lichens indicates clean air.
Come to the July 29 walk to learn more interesting facts!
