Salt marshes are extremely dynamic ecosystems, located at the interface of land and sea. An analysis of air photos taken over a 50-year period (1955-2005) has shown measurable change in these systems, including channel abandonment and spruce establishment on beach ridges. Salt marsh communities are highly diverse, ranging from tidally-inundated sedge meadows to shrub-dominated bogs. The salt marsh monitoring sites are revisited every ten years, and where possible, aerial photos and climate data from tools like Remote Area Weather Stations (RAWS) and Moderate-resolution Imaging Spectroradiometer (MODIS) are used to interpret change over time.
