Frank Shoemaker Marsh is a very diverse area of woodland, grassland, and
wetland. Saline wetland represented is saltgrass in a saline meadow;
bluestem and cordgrass also occur. There is also open water and
cattail-sedge marsh. Seaside heliotrope was collected at the edge of one
basin, on bare mud during low water, the only record of this western
species from eastern Nebraska.
An area of grassland occurs on upland on the eastern edge of the site.
There are native plants, including bluestem, gayfeather, and wild rose. This
prairie is very disturbed and would require extensive rejuvenation. There
are two areas of successional grassland. The upland site on the western
edge is predominantly rough dropseed and little and big bluestems. The shrubby
western snowberry is invading the area. On low land along the creek the
successional area is mostly Kentucky bluegrass and smooth brome. Woody
plants include ash, locust, hackberry, elm, and snowberry.
Remnant riparian woodland occurs along the eastern and western edges of the
site. The grove on the east side is almost entirely of elm, with a few
cottonwoods along the edge of the basin. The woodland on the west side of
the basin has thickets of American plum, ash, locust, mulberry, willows,
snowberry, and juniper. They are very dense in places and provide extensive
cover for wildlife. There is a replanted warm-season grassland west of the
wetland area, in which big bluestem and Indiangrass are planted.
Most of the flats along the creeks have been heavily disturbed, and
apparently an attempt was made to cultivate the property early in the
century, according to the landowner. As a result, the predominant plants
are annuals, including ragweeds, sunflowers, thistles, and Japanese brome, but
there are some native species where the ground is wet.
Water was formerly pumped from adjacent Little Salt Creek each year to
raise water levels and improve conditions for hunting of waterfowl. This influx
of freshwater may influence the salinity of the wetlands, reducing growth of
salt-marsh plants, but the water attracts a large diversity of migratory
and breeding birds.
There have been about 140 species of birds recorded at the area which is
now Frank Shoemaker Marsh. Most records are from the 1980s when it was known as
Federation Marsh, with fewer sightings since 2000. The site has a high
diversity of breeding birds included in the species list, given here in
taxonomic sequence.
