Bird species included in model

Bar-tailed godwit (Limosa lapponica), Black-tailed godwit (Limosa limosa), Common redshank (Tringa totanus), Eurasian oystercatcher (Haematopus ostralegus), Grey plover (Pluvialis squatarola), Kentish plover (Charadrius alexandrinus), Little stint (Calidris minuta), Ringed plover (Charadrius hiaticula), Sanderling (Calidris alba)

Environmental issues simulated

Salina abandonment, aquaculture intensification, changing habitat area

Recomendations from modelling

Abandonment of traditional salinas and intensification of aquaculture does not greatly effect shorebird survival as other feeding habitat available.

Baie de Seine

Bird species included in model

Dunlin (Calidris alpina), Eurasian curlew (Numenius arquata), Eurasian oystercatcher (Haematopus ostralegus)

Environmental issues simulated

Port development. Mitigation for habitat area and habitat availability time.

Recommendations from modelling

Port development can reduce shorebird survival, but mitigatation by reducing disturbance and habitat creation can offset this.

Case Study A

Bird species included in model

Eurasian oystercatcher (Haematopus ostralegus)

Environmental issues simulated

Shellfishery management changing habitat area

Recommendations from modelling

Shellfishery management needs to reserve up to 8 times more shellfish biomass than consumed by Oystercatcher populations.

Case Study B

Bird species included in model

Eurasian oystercatcher (Haematopus ostralegus)

Environmental issues simulated

Extreme cold weather increasing energy requirements, plus a recreation, shellfishery and unspecified drivers causing disturbance

Recommendations from modelling

Disturbance from human activities more likely to reduce shorebird survival when feeding conditions or weather poor.

Case Study C

Bird species included in model

Dunlin (Calidris alpina), Eurasian curlew (Numenius arquata), Eurasian oystercatcher (Haematopus ostralegus)

Environmental issues simulated

Hunting, cockle fishing, human recreation, Spartina encroachment, changing sediment levels

Recommendations from modelling

Intertidal hunting, shellfishing of large prey, and many short-term (rather than fewer long-term) disturbances had greatest negative effects on shorebird survival.

Bird species included in model

Dark-bellied brent goose (Branta bernicla bernicla)

Environmental issues simulated

Changes in land use, fungal infection, human recreation and hunting changing habitat area and availability time

Recommendations from modelling

Loss of terrestrial habitat has greater impact on brent goose than loss of intertidal habitat. Presence of hunting, through disturbance, reduces brent goose mass gain rate.
