(VA) (Arlington Parks) Did you know that the map lichen found in Virginia can live to be 8,600 years old? Though easy to miss, lichens are fascinating partnerships between algae and fungi that come in a beautiful range of colors and shapes. In winter when animals and plants are resting, it is a great time to observe lichens. First, we’ll learn about lichens in the classroom and then grab our magnifying glasses to look at them in nature!  Ages 13 and up.
