Ohio Gall Atlas 1.0

Ohio Gall Atlas 1.0
Still very much a WIP, I am sure that there are some spelling and host errors. I will try to update this a few times a year as long as I am in the state.

Here is the breakdown of current gall species # by county (only species included below). Including thanks to the major contributors to gall observations for various counties. In general thanks to @malisaspring without whom we would be missing many of the most rarely surveyed counties.

Some holes that I am interested in filling/would appreciate help with:

  • Diplolepis galls – Prairie/wetland sites – Rosa palustris/Rosa carolina/Rosa setigera – if anyone is aware of any sites with high concentrations of these species, I would love to know about them. If you have a local patch go out and take a look for leaf and stem galls.
  • Post Oak sites – Fayette, Clinton, Highland, Ross, Pike and SE Ohio in general. If anyone is aware of any sites with post oaks in these counties, LMK. There are scattered trees in SE Ohio, but I have been unable to track down a concentrated site. For the western Ohio counties, they are listed as native, but I suspect they are very rare outside the Darby Plains.
  • Quercus falcata sites – if anyone is aware of any concentrated Q. falcata sites, I would like to survey them next year. I looked for them in Jackson County this year with no luck. According to herbarium records might be some good spots in Lawrence and Scioto counties.
  • Are there any galls on Ohio C. laevigata individuals? – Clermont County Population. Found a bunch of galls on these in S. Indiana on my trip this summer, would love to know if any of them made the jump to the few trees that are native to Ohio.
  • Less charismatic galls, blisters and bumps. Cynipid twig galls.
  • The following areas of the state need more surveying – NW Ohio-particularly rural counties, W Ohio (Mercer, Darke, Preble, Shelby), Youngstown metro (Trumbull/Mahoning), Belmont/Monroe county, Deep South Ohio (Meigs, Gallia, Lawrence counties), SW Ohio rural area (Fayette, Clinton, Highland, Brown counties) if you live in or close to these counties documenting the gall fauna in them would be amazing. I will definitely be hitting Fulton/Williams/Defiance/Putnum next year as well as Meigs/Gallia/Lawrence.
    -An extensive spring phylloxera survey on hickory

My favorite gall hunting spots in the state for diversity of species
Chaparral Prairie SNP, Adams County – Post Oak, Blackjack Oak, Prairie Forbs. Highest post oak concentration that I have found in the state.

Daughmer Savannah SNP, Crawford County – Bur Oak, Shingle Oak, Prairie Forbs. Most diverse bur oak site in the state.

You should visit Hamilton co. more often, Tim. I know of a few good gall sites, Burnet Woods in particular.

@kemper I have intentionally tried to focus on more rural/less surveyed areas this year, but I would love to make it down there at some point (I need an excuse to go to Jungle Jims anyway). Random- do you know if the native passiflora site mentioned in herbarium records (I think it was a railyard or something like that iirc) that is in Cincinnati is still extant? That would be worth a trip for sure.

Lähettänyt calconey 7 kuukautta sitten (Lippu)

If it was at a railyard, its original site has likely been overtaken by development. Not too many areas in Greater Cincy are undeveloped tracts of land anymore. Yellow Passionflower is apparently known from Sharon Woods going by @celebrai 's observations but I haven't seen it myself.

A second note -- maybe changing the listing for Celticecis expulsa to "locally common" might fit? I myself saw it on most hackberry trees in Cincinnat in mid-late Spring.

Thanks, I have not seen that one at all in the NE. I updated with your comment. Looks like the Passiflora was last documented in 2006. Abundant - "Spring Grove Ave, between Kahns meat packing plant and the railroad yard"

A quick look on google maps, looks like the site is now Rhinegeist Brewery, but it looks like there might be some scrub in the back next to the railroad so there is hope.

I have some gall pics I haven't posted yet, ones hosted by Jewelweed, shingle oak, goldenrod, giant ragweed, black walnut, hawthorne, hickory, witch hazel and river birch. I know we have roses, elm trees, wild grapes, blueberries, joe pye weed, christmas ferns, juniper, various pines, willows, and pears trees on the property. Since the seasons are awry I have flora both budding and not dropping leaves so they are worth a check. Lots of names on your list I don't recognize but probably have.
Additionally, I live right on the border of Jefferson/Harrison county. I've only perused my immediate area for galls. But I have a wildlife area and very underused state park I frequently explore. I will look up your wish list and take a little trip soon. Thanks for the shout out!
