This content is excerpted from the GEMS Phase I Report: Oyster Reef Restoration.
The general ecosystem service logic model (ESLM) was developed through a multi-step process with input from oyster restoration experts and local stakeholders. The general model includes all potential dominant outcomes – meaning that the effect on the outcome from oyster reef restoration is expected to be large, tightly linked to oyster reef restoration, and important to the local community. We identified dominant outcomes through a combination of online surveys distributed to oyster restoration experts, discussions with stakeholders at workshops in each of the five focal estuaries, structured phone interviews with additional stakeholders, and literature review to compile the evidence library. The model shown here differs from the model used to identify dominant outcomes at the local workshops because it reflects updates from phone interviews and literature review conducted after the workshops. The technique-specific ecosystem service logic models were based on an older version of the general model, so they do not reflect the updates in the general model shown above. They will be updated to match the final version of the general model.
This is a general ecosystem service logic model for oyster reef restoration. It is not tied to any one of the six restoration techniques; rather, it represents all of the outcomes from those techniques that are dominant – large, tightly linked to oyster reef restoration, and important to the local community. Ecosystem service logic models specific to each restoration technique can be downloaded here (PDF).
The model shows the cascade of changes that restoration (dark blue box) causes in the biophysical and social systems (gray boxes), leading to effects on ecological outcomes (green boxes) and socioeconomic outcomes (light blue boxes). Some of the intermediate components (gray boxes) could be considered ecological outcomes; we chose to focus on ecological outcomes on the right side of the model (closer to the socioeconomic outcomes).
