Agrifos Consent Order 7984 (referred to as Nichols Mine) is a 0.3-hectare
seepage wetland located in Agrifos' Nichols Mine. It was planted in 1993 and is adjacent
to the 25-year floodplain of Thirty Mile Creek, a tributary of the North Prong of the
Alafia River. The primary water inputs to this seepage wetland include groundwater
seepage, rainfall, and runoff from the surrounding pasture uplands. The water depth
ranged from 0-12 cm. Clayey overburden soil was used in construction to simulate a
hardpan. The site was mulched prior to understory planting, with nuisance species
control occurring in 1997. Canopy species planted include Acer rubrum, Fraxinus
caroliniana, Ilex cassine L. (dahoon holly), Magnolia virginiana, Myrica cerifera L.
(wax-myrtle), Nyssa sylvatica, Persea palustris (Raf.) Sarg. (swamp-bay), and Taxodium
distichum. Shrubs planted include Cephalanthus occidentalis L. (common buttonbush),
Itea virginica L. (Virginia-willow), and Lyonia lucida (Lam.) Koch. fetterbushh).

 Cargill HP5-Phase 3 (referred to as Hydric Hammock) is a forested wetland
sloping into a Cladium jamaicensis (sawgrass) marsh bordering a lake. Hydric
Hammock is located on Cargill's Hooker's Prairie Mine. There was no standing water at
the time of sampling. This 0.8-hectare fringing forested wetland was first planted in early
1992 with Acer rubrum, Gordonia lasianthus, Ilex cassine, Liquidambar styraciflua,
Magnolia virginiana, Persea palustris, Quercus laurifolia Michx. (swamp laurel oak),
and Quercus nigra L. (water oak). The only shrub planted was Cephalanthus
occidentalis. Magnolia virginiana was re-planted in 1992 due to poor species survival
initially. No understory was planted.

 Mobil MO10 FM6 Land and Lake (referred to as Mobil Cattail) is a fringing
wetland planted in 1992. The mean water depth at sampling was 21 cm, with a range
from 6 to 31 cm. The major tree species planted included Taxodium distichum and
Taxodium distichum var. nutans (Ait.) Sweet (pondcypress).

 The CFI Industries wetland (referred to as CFI Primrose) surrounds a stream.
The water depth during sampling ranged from 0-2 cm. This site was never intended as a
forested wetland, so no tree species were planted following site establishment.
Accordingly, this site appears to be in a state of arrested succession, developmentally
behind some sites, which are chronologically older.

 Cargill East Farmland Cateye IMC31 (referred to as Cateye) is a fringing
wetland located at the Phosphoria Mine. It had no standing water at the time of sampling
(water depth 0 cm). This wetland was narrow, ranging from 15-40 meters wide and was
constructed in 1987.

 Mobil FM SP11 CAR 18 (referred to as SP11) is located at the Fort Meade Mine.
It was planted in 1985 and is approximately 20-60 meters wide. SP11 had a depressional
area through its middle perpendicular to the constructed lake it borders. At the time of
sampling, there was no standing water (0 cm water depth).
