| Notes | The Salmon River Estuary is well known for having undergone major work to remove dikes and to restore its tidal marshes. In 1962, three tidal marshes were diked to provide pasture land. These dikes have now been sequentially removed: Mitchell Marsh in 1978, Y-Marsh in 1987 and Salmon Creek Marsh in 1996. One undisturbed tidal marsh is used as a reference for natural biodiversity. This Master’s thesis reports on how vegetation changed in all the marshes during the period from 1988 to 2015. “Results indicate that there are significant differences between the vegetation composition of the restored marshes and the remnant marsh. Restored marshes have become more similar to one another over time but have not returned to their expected reference conditions in the time since restoration” (from the Abstract). Colored maps, charts, very nice data visualization. |
