Bay of Fundy
Improve Flood Protection
In 2010, Ducks Unlimited Canada (DUC) performed a controlled breach of two sections of dyked land on the upper Bay of Fundy near Aulac, New Brunswick.
A new seawall (dyke) was constructed inland to protect remaining pastured while allowing tidal flooding to return to the area between the old and new walls. Interesting work was done on this site to describe the carbon sequestration rates in this restored wetland (Wollenberg et al., 2018).
This study measured the high level of accretion in the site (up to 102 cm after 6 years) and calculated the sequestration rate as 1,329 g C m-2 yr-1. This was found to be more than more than five times the rate reported by the same study in a nearby mature marsh.
