Fresh Air Moments

The Highlands Center For Natural History is committed to staying connected with you and the natural world. Everyday for as long as our public programs are postponed or cancelled, our education staff will be sharing place-based nature and science-related posts. These posts are intended to be interactive, shared, and to be a resource for all people. These “Fresh Air Moments” are our way of encouraging everyone to take a moment outside everyday – on your porch, in your backyard, walking on the sidewalk, or on local trails like here at the Highlands Center.
