High/Low CC Plants (Bolded above)

Starting with our highest CC value plants which are: American Sycamore (Platanus occidentalis), White Ash (Fraxinus americana), Drummonds Aster (Aster drummondii), and American Bladdernut (Staphylea trifolia). This range (6-8) of CC values indicates that the plants are in stable or near climactic conditions. It has a high CC because it has a relatively narrow range of ecological tolerance.

Our low CC plants are Geulder Rose (Vibrunum opulus), Amur Honeysuckle (Lonicera maackii), Northern Catalpa (Catalpa speciosa), Poison Ivy (Toxicodendron radicans), and Blackberry (Rubus allegheniensis). These plants have CCs of either 0 or 1 meaning they have a widespread range of ecological tolerances and aren’t particular to any one area/community.

Invasive Species

Multiflora Rose (Rosa multiflora): Multiflora rose is an invasive plant native to China, Japan, and Korea that was introduced to the U.S in the 1860s. It is highly prevalent in the Midwest and the northeastern states and was for a while promoted for controlling erosion and roaming farm animals. Can be mistaken for plants like blackberry due to its thorns and pinnate leaflets, but if you look closely there are stipules and in fruit you can see the rosehips.

For some reason the camera decided not to focus on the plant, but you can still see the pinnate leaflets and the stipules of this Multiflora Rose


English Ivy (Hedera helix): English Ivy is an invasive evergreen vine that kills many surrounding plants and can dominate the areas they are in. It was introduced to the U.S around 1727. Their berries are toxic to humans but are enjoyed by many birds which also furthers its spread. The leaves are dark green with lighter green/white veins and are deeply lobed forming almost three leaflets but not quite.

Japanese Snowball (Viburnum plicatum): Native to Japan and China, this is a common urban tree that is invasive in the Midwest and northeastern states. It is common in gardens and yards. The leaves are very distinctively shiny, very veined, toothed, and opposite.

Oriental Lady’s Thumb (Persicaria longiseta): Native to Southeast Asia and has become very widespread across the U.S and Europe. It invades and displaces native species and tolerates a wide range of climates. It can be identified by its pink-purple spikes of flowers and its alternate lance-like leaves (which can be hairy).

Substrate Associate Species (Geobotany)

There are many plants here that point towards limey soil which is strange to me considering the site is so close to an outcropping of the Ohio Shale (which was once overlain by sandstone). So it must be close to the glaciation boundary where the sandstone is weathered away and there is a lot of limey sediments left by the glaciers. Some plants of relatively limey areas are: redbud (Cercis canadensis), hophornbeam (Ostrya virginiana), and hackberry (Celtis occidentalis). Some plants of high lime areas are: sugar maple (Acer saccharum), red oak (Quercus rubra), and white ash (Fraxinus americana).
