SL229: Landscape Diversity: Multiple-Use Landscapes for Reclaimed Phosphatic Clay Areas

Figure 2. The same site is shown after clay deposition, reclamation, and several years into the differential settling process. Note that the berm has been reshaped and managers have used the multiple-use landscape approach immediately after reclamation of the surface. Tree planting and location of access roads are based upon underlying strata. Deeper zones of phosphatic clay have been set aside for water and wetlands. Filter strips surround these low areas. An assortment of crops (sod, energy crops, forages, native grasses for seed/transplanting) is positioned in the landscape based upon slope and drainage considerations. In this concept drawing, differential settling and original underlying strata have occurred at different rates. Note that the underlying strata is used as a road (left side of drawing and to the immediate right of trees) since this material extends to the surface. The phosphatic clay to the right of that road contains row crops and a swale in the middle for drainage and water quality considerations. Steeper land (far right on the side of the residual berm) is in grasses for stability on the slope.
