| This project explores the mechanisms for the development of patterned landscapes in the Everglades, focusing the process of peat accretion. The restoration of the Everglades requires actionable information about how to better manage water resources, and one of the key elements is to restore the processes that historically maintained a highly diverse and strikingly patterned mosaic of ridges, sloughs and tree islands. It has been shown that the landform that creates ridges (which occupy higher elevation soils) and sloughs (on lower elevation sites) is not a reflection of bedrock elevations, meaning that the pattern (both vertically and horizontally) is due to self-organizing feedbacks between the vegetation, hydrology and soil elevation. Our work has been on the mechanisms of alternative stable configurations of vegetation that yield the same peat accretion rate (i.e., ridges, sloughs and tree islands), the controls on those peat accretion rates that would be revelant to restoration, and the mechanisms that create marked linearity in the shapes of ridges and sloughs. This work is ongoing. |
