Why iNaturalist Matters
iNaturalist is a global community science platform where people of all experience levels document the living world together. Observations become part of an open database that supports researchers, conservationists, and land stewards who want to understand how species are changing over time.
The Philadelphia Mycology Club uses iNaturalist to help members learn, share discoveries, and contribute high-quality fungal records. Every upload strengthens our collective knowledge and creates a welcoming pathway for new naturalists to engage with the ecosystems around them.
