A simulation model for projecting changes in salinity concentration and species dominance in the coastal margin habitats of the Everglades Methods Results Equations Introduction A study model located in the Everglades Region of South Florida, that projecting changes in salinity concentration and species dominance, (Mangroves and hardwood hammocks in this region). Mangroves and hardwood hammocks have very stable and sharp boundaries due to the sensitivity of the hardwood hammocks to salinity, restricted to areas with salinities below 7 ppt. on the other hand mangroves are able to tolerate a wide range of salinities, above 30 ppt. If these stabilize boundaries get disturbance by large event like storm surges, a vegetation shift from hardwood hammocks to mangroves may happened due to increase salinity in vadose zone. Conclusion The model is designed to determent the regime shift between mangroves and hardwood hammocks types

Unformatted text preview: that might be triggered by large storm surge. 1-day storm surge could initiate a vegetation shift. More than 15 ppt of saturates vadose zone by storm surge is enough for mangroves to take over higher elevation cells, while less than 7 ppt of saturated vadose zone will not cause any vegetation shift. Another important factor in the growth of mangroves in the higher elevation cells is the thickness or depth of the vadose zone. Thicker vadose zone will have larger volume of high salinity which takes longer to be flushed out by precipitation. With time the mangroves will continue growth while hardwood hammocks will suppressed.
