This guidebook provides photos and descriptions of the ferns and mosses found at Caledon State Park in King George, Virginia. It's a fun guide to take with you as you explore the many trails at the park so you can identify the various ferns and mosses. This project was started by Martha J. Shelkey and picked up by her daughter, Debbie Shelkey-Lawson. Martha Shelkey is a one-thousand-hour volunteer at the park for all her work cataloging the ferns, mosses, mushrooms, plants, and wildflowers found at the park.
