Shield lichens are a group of lichens known for their impressive ability to thrive on tree bark and rocks in diverse climates, ranging from tropical to temperate regions. These lichens often form leafy, shield-like structures that can be quite striking. Among their many fascinating traits, shield lichens can withstand harsh environmental conditions, making them valuable bioindicators for monitoring air quality. Their symbiotic relationship with algae allows them to produce food through photosynthesis, contributing to their resilience.
