O’Shaugnessy Nature Preserve is home to numerous sugar maple trees, asters, various lichens and mosses, and especially poison ivy! The Scioto River branches into the reserve and then further divides into Eversole Run. Within the park, there are few grass paths that run along the river and some that go into the forrest. Most of the herbaceous plants were found along these grass paths; whereas the moss was found inside the forest. Invasive species were found in both the forest and the grass plants. As for touring the park, it is a great place for fishing and walking your pets; however, it would be very difficult to have a picnic since all of the concrete tables have been eroded.
Two New Trees
Ashleaf maple (Acer negundo)
Osage-orange (Maclura pomifera)
Interesting fact of the Osage-orange: Osage-orange has a variety of uses: the wood was first used by the native Americans to make their bows, settlers used the wood to build fences around their farms, and currently researchers are determining the potential of its extracted oil as a potential biodiesel.
Two New Shrubs or Woody Vines
Running Strawberry Bush (euonymus obovatus)
Interesting fact of Running Strawberry Bush: The running strawberry bush is either considered a woody vine or a small shrub. This plant ought not to be planted near cattle farms, because it is well-known for killing livestock.
Canada moonseed: (Menispermum canadense)
Two New Herbaceous or Fruiting Plants
Lady’s Thumb (Polygonum persicaria)
Interesting Fact of Lady’s Thumb: Native Americans used Lady’s thumb as remedy for stomach pains, relieving poison ivy rashes, and as an insect repellent on their horses
Teasel (Dipsacus sylvestris)
Poison Ivy (Rhus radicans)
Key features of poison ivy: Leaflets of three; leaflets are entire, but sometimes have coarse teeth; fruit grow from leaf axils, and are grayish-white.
Two Types of Lichens
Hairless-spined Shield Lichen (Parmelinopsis minarum)
Description: I found this lichen growing on the side of a very tall tree. A key feature of this foliose lichen is that the uppersurface is coated with very small isidia.
Common Powderhorn (Cladonia coniocraea)
Description: I found this fruticose lichen growing on an old fence post. Those appendages are called podetia. The podetia are sterile.
