Environmental Concern, Inc. (EC), a public non-profit Corporation, was founded by Dr. Edgar Garbisch.
Dr. Garbisch took a leap of faith and by trial and error, successfully restored the first marsh in the Chesapeake Bay Watershed. Hambleton Island, once a 55 acre land mass in the mid-nineteenth century, had eroded to half that size by the early 1970s. In addition to the natural erosion, the island had also breached near the center. After a few false starts, 300 barge loads of sand, 25,000 seedlings of cordgrass (Spartina alterniflora) and salt marsh hay (Spartina patens), and five months of planting, the island breach had been restored.
