I'm not going to get overly consumed with trying to install plants with a high CofC score. I only want to use the score as a way to quantify my success at creating the conditions necessary to support a more specialized plant community. I've been excited to see two American Beech seedlings emerge on my lot because I didn't plant them and because they have a CofC of "7" which is high for my lot. If I force them to exist it's different from creating the conditions for them to exist.
One thing that jumps out at me when I look at this is... There are 13 species of non-cultivated native plants on our lot with a CofC of 6 or higher. Out of these 13, a total of 11 are tree species. This is surprising because there are far more herbaceous layer plants on our lot than tree species. One possible explanation is that the canopy trees have long lives and the canopy exists above plants like honeysuckle, garlic mustard, and celandine. All of the specialized herbaceous layer plants may have been overtaken by invasives long enough in the past for their seed bank to have been exhausted. Meanwhile, the canopy trees existing above the honeysuckle continued adding to the seed bank and waiting for it to be unlocked.

Has expanded aggressively following invasive removals.
Smooth Rockcress (Borodinia laevigata)
4
Naturally Occurring
Smooth Solomon's Seal (Polygonatum biflorum)
4
I just realized in 2023, after 16 years working on this, that I have some of these mixed in with the Maianthemum Racemosum. They aren't as common and aren't noticeable until they bloom. In the early years most of the individuals in both colonies were eaten by deer before they had a chance to bloom.
Sweet Cicely (Osmorhiza)
4
I did not notice this at anytime while clearing honeysuckle or at any time in the past 15 years on our lot. Pretty sure this came to exist on our lot only after invasive removals. It's pretty common, but hadn't seen it here before.

My understanding is that Black Locust is a native tree east of the Appalaichans, but not native to Ohio (hence the 0 CofC).
Bedstraw (Galium aparine)

There is some debate over whether or not this is a native plant. I'm including it in this list but with a CofC of 0.

American Holly (Ilex opaca)
?
One american holly seedling has emerged following invasive removals.
Callery Pear
Seedlings emerge more frequently post honeysuckle removal. Once the under-story and canopy recover, I expect to see fewer Callery Pear seedlings.
Tree of Heaven
Seedlings emerge more frequently post honeysuckle removal. Once the under-story and canopy recover, I expect to see fewer Tree of Heaven seedlings.
Burning Bush
Seedlings emerge more frequently post honeysuckle removal. Once the under-story and canopy recover, I expect to see fewer Burning Bush seedlings. They're easy to stay on top of as long as I pull them every year when young.
Liriope (Liriope muscari)
Expanding, but slowly. Planning to completely knock it out this year before too many plants develop.
Carpet Bugle (Ajuga reptans)
Been holding these in check, but need to work a little harder to completely extirpate.
Winter Creeper (Euonymus fortunei)
Stable or possibly declining but only because I stay on top of it. Less aggressive in shade.
Creeping Charlie (Glechoma Hederacea)
Not a battle I'm currently choosing. This stuff exists, but isn't widespread, doesn't expand much, and doesn't crowd anything out.
Hairy Bittercress (Cardamine hirsuta)
Not a battle I'm currently choosing. This stuff exists, but isn't widespread, doesn't expand much, and doesn't crowd anything out.
English Ivy (Hedera helix)
Stable on my lot... I pull new outcroppings every year. Expanding on neighboring lots, could become a bigger problem.
Low Smartweed (Persecaria longiseta)
Not a battle I'm currently choosing. This stuff exists, but isn't widespread, doesn't expand much, and doesn't crowd anything out.
Oriental Bittersweet (Celastrus orbiculatus)
Purple Deadnettle (Lamium purpureum)
Not a battle I'm currently choosing. This stuff exists, but isn't widespread in the shade, doesn't expand much, and doesn't crowd anything out.
Japanese Honeysuckle (Lonicera japonica)
Pull it every year to keep the population stable. This is another one where shade helps keep it from growing quickly.
Lesser Celandine (Ficaria verna)
Currently the one plant I spend the most time on. Have to work like crazy just to keep the population from expanding.
Multiflora Rose (Rosa multiflora)
Not a big problem here. I notice new ones every year or two, but they're easy to pull when I see them.
Bush Honeysuckle
This is much less work now that all of the large plants have been removed.
Definitely declining in terms of biomass needing to be removed, but still pull lots of seedlings every year.
Purslane (Portulaca oleracea)
Used to notice this more often shortly after invasive removals. More dense canopy, understory, and herbaceous layer are shading it out..
Rose of Sharon
It's taken years to get ahead of this one, but it is now declining. Still have to pull a few every year.
Star of Bethlehem (Ornithogalum umbellatum)
Exists in clumps here and there. Not nearly as common in shadier areas.
Creeping Jenny (Lysimachia nummularia)
Close to being extirpated. Haven't seen any this year, so I'm hoping I got it all.
Dandelion (Taraxacum officinale)
Saw more of them shortly after initial invasive removals when more sun was able to hit the ground. See very few now. Shade is doing the work for me.
Garlic Mustard (Alliaria petiolata)
I have to pull a little less every year. Take a long time getting ahead of this one... but I'm slowly getting there.
Japanese Maple (Acer palmatum)
A single japanese maple seedling emerged a few years ago. I was going to let it go just to see what would happen but it didn't come back the following year.
Creeping Bellflower (Capanula rapunculoides)
Had a couple of these pop-up one year. I didn't remove them, but they didn't come back. This was shortly after initial honeysuckle removal when there was lots of sun hitting the forest floor.
Curly Dock (Rumex crispus)
Had a couple of these pop-up one year. I didn't remove them, but they didn't come back. This was shortly after initial honeysuckle removal when there was lots of sun hitting the forest floor.
Moth Mullein (Verbascum blattaria)
Had a couple of these pop-up one year. I didn't remove them, but they didn't come back. This was shortly after initial honeysuckle removal when there was lots of sun hitting the forest floor.
Mullein (Verbascum thapsus)
Had a couple of these pop-up one year. I didn't remove them, but they didn't come back. This was shortly after initial honeysuckle removal when there was lots of sun hitting the forest floor.
Periwinkle (Vinca Minor)
Pretty sure I've finally removed all of it.
Poison Hemlock (Conium maculatum)
Haven't had any come up in several years.
Variegated Solomon’s Seal
White Mulberry (Morus alba)
Wild Grape Vine (Vitis spp)
Yellow Rocket (Barbarea vulgaris)
Haven't come across any of this for a long while.
