Other Considerations

No human activities that are incompatible with the conservation of the ecological components of interest may occur or be foreseeable within the area.

Environmental Context

The Magdalen Islands lagoons act as spawning and breeding grounds, nurseries, and refuges for many aquatic species.

By protecting the bottom habitat, this closure can also help protect the habitat of numerous other species of fish and invertebrates including commercially important species such as Atlantic surf and razor clams, winter and yellowtail flounder, and Atlantic herring.

This closure contains eelgrass habitat, an ecologically significant species (ESS) and a highly productive ecosystem that can support a wide variety of species in key life stages. Marshes, which are a unique coastal habitat, are also present in this area.

This closure also helps protect the habitat of the threatened American eel.
