This study investigates the diversity of organisms associated with lichens and examines variations in lichen morphology across areas with differing levels of human interference. Lichen samples were collected from three locations: a school backyard (representing a high-pollution area), 2 Linda Court (low-pollution area), and 4 Ginny Drive (medium-pollution area). Pollution levels were characterized by the extent of human activity in each area. The findings hopefully will contribute to understanding the relationship between environmental conditions and lichen-associated biodiversity, as well as morphological variation in lichens across different pollution levels.
