Black brant (Branta bernicula nigricans)
Natural variation, sea-level rise / sediment change and recreation changing habitat area, habitat availability time and food quality
Increased disturbance from human activities or reduced food supply reduce emigration of black brant.

Black brant (Branta bernicula nigricans), Taverner’s cackling goose (Branta hutchinsii taverneri)
Human recreation, hunting, predator numbers, ice and extreme weather changing habitat area, habitat availability time, food availability and energy needs and requirements
Habitat loss, disturbance colder weather have greater impact on black brant geese when eelgrass food biomass is lower.
