Symbiotic Relationships and Plant Identification

Jeanette, a naturalist, explores Big Rock Forest Preserve, identifying an ash tree by its bore holes and tracks left by the emerald ash borer. She discusses moss, its evolution from algae, and its uses by Native Americans and in World War I. Lichen, another ancient organism, is explained as a symbiotic relationship between algae and fungus, used by ancient Egyptians and birds. Jeanette concludes by encouraging viewers to explore nature.
