Map of Adena Brook near N High Street

In my botanical survey site, I inventoried new trees, vines, and flowers. I surveyed the Adena Brook ravine. This ravine is home to mesic and wet-mesic forest ecosystems. This site is just off North High street, about 2 miles from OSU campus. This site features both a public park on the western side as well as forested land adjacent to residential streets on the eastern side. On the western side of the site, the brook flows into the Olentangy river. I have yet to explore this part. This land is likely managed for recreational and aesthetic purposes and likely does not support many rare species, although I was still surprised by its diversity.


white heath aster (Symphyotrichum ericoides)

Canadian goldenrod (Solidago canadensis)

green ash (Fraxinus pennsylvanica)

I was surprised to find ash trees in this site, due to most of them in the area being wiped out due to emerald ash borer. This tree was about 3 inches in diameter but will soon likely meet its fate as emerald ash borer are known to attack trees 1 inch diameter and larger.

American sycamore (Platanus occidentalis)

This is a celebrated native Ohio tree. Its distinctive bark and large leaves make it a common ornamental as well. It favors wet soils and can grow quite large and can live to be very old. The largest in the state (state champion tree) is over 11 feet in diameter!

riverbank grape (Vitis riparia)

This native climbing vine can be found quite commonly throughout the Columbus area. This is a long-lived vine who will scale even the largest of forest trees. It produces an edible fruit and is commonly used as rootstock in grafting other grape vines for cultivation.

poison ivy (Toxicodendron radicans)

Leaflets of 3, let it be! This common woody forest vine is likely one of the most well known woody forest plants for one reason: it causes dermatitis. This plant is identifiable by its many hair-like aerial roots and its 3 distinct symmetrical leaflets with the outer two having a mitten-like shape. Some people seem to be immune to the oils this plant produces while others get a nasty rash. A common treatment of a poison ivy rash is crushed jewelweed, another common native forest plant.
