Abstract: The consulting firm of CE Maguire, Inc. was contracted by the U. S. Army Corps of Engineers to evaluate the success of 32 wetlands created to replace wetlands destroyed by filling or dredging. The wetlands evaluated lie in Virginia's coastal zone. They include tidal and inland wetlands ranging in size from 300 square feet to more than 10 acres. A wide variety of techniques were used to create the wetlands. Excavation and the sprigging or transplanting of wetland vegetation were typically involved. The scale of the wetland construction ranged from a day of manual labor to a major regrading and helicopter transport of marsh vegetation. The evaluation found that most of the replacement wetlands have been successfully established. A number of replacement wetlands failed to meet the permit requirements.
