List of species at Waterman Farm

The following list of species are all plants that I have found at my Waterman Farm site. I have listed a common name for the species, followed by the scientific name, followed by the Coefficient of Conservation value set forth in the 2014 update to the EPA Floristic Quality Index.

boxelder Acer negundo – 3

red maple Acer rubrum – 2

sugar maple Acer saccharum– 5

downy serviceberry  Amelanchier arborea– 5

shagbark hickory Carya ovata– 6

catalpa Catalpa sp.– 0

hackberry Celtis occidentalis– 4

chicory Cichorium intybus– 0

Amur honeysuckle Lonicera mackii– 0

burningbush Euonymus alatus– 3

American beech Fagus grandifolia – 7

blue ash Fraxinus quadrangulata– 6

black walnut Juglans nigra– 5

spicebush Lindera benzoin– 5

pawpaw Asimina triloba– 6

poison ivy Toxicodendron radicans– 1

Virginia creeper Parthenocissus quinquefolia– 2

black raspberry Rubus occidentalis– 1

pin oak Quercus palustris– 5

eastern redcedar Juniperus virginiana– 3

white ash Fraxinus americana– 6


FQAI = 16.513

I believe that this value indicates my site is on the lower end of average floristic quality, which also correlates with my personal observations of the site.



American beech – Fagus grandifolia – CC=7

This beech can be identified by its thin, papery, serrate leaves and characteristic smooth light gray bark. According to the University of Kentucky Department of Horticulture, beeches are of relatively low timber value despite their large size.







pawpaw – Asimina triloba ­– CC=6

This pawpaw can be identified by its large smooth rounded leaves and distinctive smell, reminiscent of a green bell pepper. Pawpaws bear a large fleshy fruit that is delicious for human consumption in the late fall!







black walnut – Juglans nigra – CC=5

This walnut can be identified by the diamond furrows in the bark, large compound leaves, and distinctive large green fruits. The U.S. Department of Agriculture states that TCD (thousand cankers disease) is an emerging disease causing widespread mortality of black walnuts in the western half of the country.








white ash – Fraxinus americana – CC=6

This white ash can be identified by the brown “chocolate chip” bud characteristic of the genus, and by the unique shape of the leaf scar. White ash, along with hickories, have wood with excellent shock-resistant qualities and are thus often used for axe handles, according to The Wood Database.








FOUR LOW CC species

black raspberry – Rubus occidentalis – CC=1

This black raspberry can be identified by the 5-lobed leaves and thorny stalks.Black raspberries bear a delicious fruit, which is an aggregate of drupes, in the late summer.







poison ivy – Toxicodendron radicans – CC=1

This poison ivy can be identified by its distinctive trifoliate leaves in an arrowhead shape. Poison ivy, while potentially harmful to humans is a nutritious food source for many species of birds.







chicory – Cichorium intybus – CC=0

This chicory can be identified by its distinctive purplish aster flowers. Chicory was often used as a substitute for coffee during the Second World War, but supposedly has a slightly nuttier flavor, according to The Smithsonian.







catalpa – Catalpa sp. – CC=0

This catalpa can be identified by its large smooth green leaves. According to, catalpa leaves and bark have a wide variety of medicinal uses.








burdock – Arctium sp.

This burdock can be identified by its tall structure and characteristic fruits. Burdock has a two-year life cycle, bearing big leaves laying flat against the ground in the first year, and shooting up several feet to bear fruit in the second year. There is a lot of burdock at my site, but I took this photo at Chadwick Lake near OSU campus.








Amur honeysuckle – Lonicera mackii

This honeysuckle can be identified by its dark green leaves, red fruits, and hollow pith. Honeysuckle remains green late into the winter and is one of the earliest woody plants to leaf out in the spring, easily outcompeting other native plants.








English ivy – Hedera helix

I identified this ivy by its distinctive glossy dark green arrowhead-shaped leaves and whitish veins. English ivy is detrimental to many trees because of its tendency to burrow under the bark and encourage rot and decay, according to the University of Maryland. I took this photo at my house in north Columbus.







vinca – Vinca minor

I identified this vinca by its distinctive glossy smooth and rounded leaves. The Invasive Plant Atlas claims that Vinca was first introduced to the United States in the 1700’s but has quickly spread since then. I took this photo at my house in north Columbus.








red maple – Acer rubrum

I identified this red maple by its V-shaped indentations between lobes. Forsyth classifies this tree as being abundant in more limey soils. I would agree with this classification, as my study site is placed within the western half of Ohio and thus should have a more limey substrate.






pin oak – Quercus palustris

I identified this pin oak by its smooth bark (not furrowed like a red oak), and leaves with long, skinny and point-tipped lobes. Forsyth classifies this tree as thriving in the high-lime clay-rich till of Western Ohio. I would agree with this, as these oaks are abundant in a treeline of my site which is located within western Ohio.







blue ash – Fraxinus quadrangulata

I identified this blue ash by the square edges to the twig tips. Forsyth classifies this tree as being abundant in the high-lime clay-rich till of western Ohio. I would agree with Forsyth’s classification even though blue ash is not very abundant at my site, as I assume emerald ash borer is the chief culprit in this particular situation.









sugar maple – Acer saccharum

I identified this sugar maple by its U-shaped indentations between leaves. Forsyth classifies sugar maple as representative of the high-lime clay-rich till of the Ohio plains. I would very strongly agree with Forsyth here, as sugar maple is one of the most common trees at my site which is located at the edge of the Western Ohio plains.
