The implementation of salt marsh Inventory & Monitoring protocols at Cape Cod National Seashore in 2003 led to the discovery of large areas of vegetation loss within the seashore.
Unbeknownst to NPS staff, something similar had also been found a year earlier in several marshes outside the seashore (reported by R. Rozsa and S. Warren - see timeline link below).
