Understanding ecosystem service impacts of tidal wetlands after managed dyke realignment through causal loop diagrams

This report explores ecological dynamics involved in the provision of three ecosystem services (blue carbon, storm protection, and fisheries) associated with existing and restored tidal wetlands in the context of managed dyke realignment. These dynamics are represented in causal loop diagrams depicting negative and positive relationships between ecological variables, all explained further in the glossary at the end. Reinforcing and balancing feedback relations are highlighted through each diagram description. Diagrams are based on a review of relevant literature conducted within the Bay of Fundy dykeland landscape and can be used to inform the decision-making process in the region. Managed dyke realignment is highlighted as a coastal adaptation strategy that provides opportunities to protect and restore tidal wetlands and their associated ecosystem services.
