This guide introduces 52 South Florida ferns, including all the common species, 17 rare species, 14 endangered or threatened species, and 13 invasive species. There is minimal botanical jargon and no technical keys. After a brief introduction to fern structure and biology, species are grouped by habitat (terrestrial, epiphytic, aquatic) and basic frond structure. The text helps you focus on key features and high-quality photos show what’s needed for positive identification. Additional notes from the scientific literature give insights into fern biology and how they adapt to their environment. The references help you dig deeper if something catches your interest.
