Lvcopodium clavatum L.
Monroe County: Union Township T73N R18W Section 20 SW4 SE4 NE4 SW4
LaHart Wildlife Management Area is approximately 3 miles southwest of
Lovilia. It is owned by the Iowa Department of Natural Resources and on the
Southern Iowa Drift Plain. The collection site is in an oak/hickory forest and
west of a small ravine. The soil is mapped as Gosport-Rock outcrop complex,
14 to 40 percent slopes (478G). Typically the surface layer of Gosport silt loam
is slightly acid, while the subsoil is commonly very strongly acid. It is a Typic
Dystrochrept that formed in a thin silty mantle and in the underlying material
weathered from acid Pennsylvanian shale. Rock outcrop is typically sandstone
bedrock. Small areas adjacent to the sandstone outcrops have a surface layer
of sandy loam.
Lvcopodium clavatum is abundant on a west-facing slope just north of what
appears to be a formerly bulldozed tractor lane. It is also abundant in the lane,
which has been disturbed by fence building this year (plants crushed, soil
exposed, shrubs and saplings run over). It is also found just south of the lane.
Ramets with cones are rare and only found in the sapling-dominated area just
north of the lane. Light yellow cones are releasing yellow spores. Lvcopodium
clavatum is associated with Kriaia biflora. Parthenocissus quinquefolia. Pilea
pumila. Quercus imbricaria (sapling), Rubus sp. and Solidaao ulmifolia.
Lvcopodium diaitatum and Lvcopodium lucidulum also occur near this
collection site.
