Vascular Plants of the Bog

The Orono Bog Boardwalk traverses several different peatland environments and types of vegetation, providing a rich cross section of wetland plants.

Below is a list of vascular plant species you can see from the boardwalk. The list will be updated periodically. If you see plant species from the boardwalk that are not on the list, please inform Dr. Christopher Campbell. The numbers that follow each species indicate the interpretive station and nearby stretch of the boardwalk (and vegetation zone) where you can see that plant. The map elsewhere on this web site shows station positions relative to vegetation zones. Of course, plant species can bloom or vary in appearance as the seasons progress. Look carefully.

The plants are listed alphabetically–first by common name and then by scientific name. For those interested in learning more about these plants in Maine, visit the website of the
