Ecologically, lichen plays a significant role in the formation of flourishing ecosystems by breaking apart rock formations using small fungal threads to form fertile soil which supports a growing complexity/diversity of life. This essay uses lichen as a metaphor to describe fossilized constructs (colonial epistemologies and ontologies, neoliberalism, and white centered environmental racism) that need to be eroded within traditional environmental education. Then, lichen-supported biodiversity is used to discuss conceptualizations of decolonizing and queering ecopedagogy which can promote anti-oppressive environmental education that (re)orients and prioritizes flourishing and thriving.
