Field Trip to the Ballard Wildlife Management Area – July 31, 2021

On Saturday, July 31, 2021, for the first time since July of 2019, KNPS members were able to get out into the field as a group and explore our Commonwealth’s botanical diversity. Traveling to the Ballard Wildlife Management Area in Ballard Co., nine of us spent an enjoyable morning visiting a variety of wetland ecosystems that many Kentuckians never see.

Ballard Wildlife Management Area is 8,000 acres located in the Ohio River bottomlands ecoregion in far western Kentucky. The WMA is mostly wetland with 39% of the acreage in wetland, 28% forest, 27% open land, and 6% open water. Much of the wetland is comprised of rare, cypress (tupelo) swamps and sloughs that many Kentuckians have not had the opportunity to experience. The Office of Kentucky Nature Preserves lists cypress (tupelo) swamp as a state endangered ecosystem. The forested parts of the WMA are mostly bottomland hardwood forest, another ecosystem that is somewhat uncommon in Kentucky.

Pale Indian plantain
(Arnoglossum atriplicifolium)

The nine participants headed out in a three-vehicle caravan to visit several spots around the WMA. We were led by longtime WMA employees, Gerald Burnett and Richard Campbell. At each stop we got out and walked and found many native plants. At our first stop we spotted several nice stands of an uncommon native, pale Indian plantain (Arnoglossum atriplicifolium). We also saw several species of St. John’s wort (Hypericum spp.), downy skullcap (Scuttelaria incana), meadow beauty (Rhexia spp.), starry campion (Silene stellata), and several species of aquatic and semi-aquatic plants, including American bur-reed (Sparganium americanum), arrow arum (Peltandra virginica), and broadleaf arrowhead (Sagittaria latifolia). Lots of buttonbush (Cephalanthus occidentalis) and both species of native Hibiscus, halberd-leaf rosemallow (H. laevis) and swamp rosemallow (H. moscheutos), were in abundance along the shores of the area’s lakes and sloughs.

Oneflower false fiddleleaf (Hydrolea uniflora)

At the second stop we explored both a wetland community and a bottomland forest. We saw several natives, a couple that are rare in Kentucky. In the wetland, we saw a nice patch of oneflower false fiddleleaf (Hydrolea uniflora) in full bloom. This genus, Hydrolea, has two species in Kentucky, this one and ovate false fiddleleaf (Hydrolea ovata). Both species are only found in a couple of counties in far western Kentucky, and were believed to be extirpated until 2006 when both were observed again. Read the post “From the Lady Slipper Archives: Hydroleas (the genus False Fiddleleaf) in Kentucky – Lost and Found” to learn more about these beautiful and rare species.

Snow squarestem (Melanthera nivea)

We also encountered several stands of snow squarestem (Melanthera nivea) just beginning to flower. This is another species that is rare in Kentucky, reported only from four counties along the Ohio and Mississippi rivers; McCracken, Ballard, Carlisle, and Hickman.

Other species that were found in bloom in these habitats included sharpwing monkey flower (Mimulus alatus), butterfly milkweed (Asclepias tuberosa), swamp milkweed (A. incarnata), aquatic milkweed (A. perennis), hairy mountian mint (Pycnanthemum verticillatum var. pilosum), cup plant (Silphium perfoliatum), cardinal flower (Lobelia cardinalis), creeping burhead (Echinodorus cordifolius), and water parsnip (Sium suave).

Most of us are familiar with the non-native Asiatic dayflower (C. communis), that grows in gardens and along roadsides. However, many are not aware that Kentucky has three native dayflowers. We saw all three species of Kentucky’s native dayflowers in bloom during the field trip; white-mouth dayflower (C. erecta), Virginia dayflower (C. virginiana), and climbing dayflower (C. diffusa).

The day was a great start to getting back to in-person field trips. This exploration of an area of Kentucky that many people are unfamiliar with was a great example of the value of KNPS field trips for learning about our native plant communities.
