Description
Map lichens are a type of lichen known for their distinct, map-like appearance. They grow very slowly and are often used by scientists to date geological events, a practice known as lichenometry. These lichens thrive in harsh environments, such as rocky outcrops and alpine regions. Map lichens can vary in color, with many species displaying a characteristic yellow-green hue due to their specific pigments.
