Location of sample sites

Soil samples were taken from field sites located on the Harney River, in Everglades National Pak, Fl. The two sites are roughly 300 m apart

mangrove soil soil 1
Mangrove soil (soil #1)

Mangrove forest. Mostly red mangroves, mixed with both black and white mangroves.

Used a Russian D-corer (sediment borer) to collect soil samples.

Soil properties and Interpretations

  • low infiltration rate, low hydraulic conductivitiy
  • Seasonal high water table depth : <25 cm
  • Severe limitations for dwellings with basements, septic tank absorption fields and local roads and streets
  • Site Characteristics
  • Flood plain
  • Parent material is mangrove peat (roots and organic matter)
  • Nearly level slope
  • Very slow surface runoff
  • Low erosion potential
  • Soil Classification
  • Histosol
sawgrass soil soil 2
Sawgrass soil (soil #2)

Sawgrass (Cladium jamaicense) marsh. Located about 300m from site of soil #1.

To collect soil cores at these sites, it is a good idea to use a strong intern from Slovakia.
