The Engelmann’s Quillwort (Isoetes engelmannii), also known as Appalachian Quillwort, is an aquatic plant found along shallow ponds, temporary shallow pools, roadside ditches and marshes. It is small fern that is 20-40 cm in height but can grow up to 90 cm. It has long, thin, hollow green leaves. It is uncommon but widespread throughout eastern North America. In Canada, it is native but only found in two locations in Ontario restricted to two rivers. For this reason, it is considered endangered in Canada. Habitat destruction, recreational activities, and pollution contribute to the threat to its population. #Canada150 #Biodiversity150
