Poole Harbour
Case Study A
Bird species included in model
Black-tailed godwit (Limosa limosa), Common redshank (Tringa totanus), Dunlin (Calidris alpina), Eurasian curlew (Numenius arquata), Eurasian oystercatcher (Haematopus ostralegus)
Environmental issues simulated
Unspecified drivers affecting loss of terrestrial habitats and food supply, plus sea-level rise and extreme weather, changing habitat area and availability time, food quality and energy requirements
Recommendations from modelling
Terrestrial habitat loss and sea-level rise can reduce shorebird survival, but effects vary between species.

Case Study B
Bird species included in model
Eurasian oystercatcher (Haematopus ostralegus)
Environmental issues simulated
Invasive species changing food density / quality
Recommendations from modelling
Presence of non-native shellfish, by providing additional food, can increase Oystercatcher survival.

Case Study C
Bird species included in model
Avocet (Recurvirostra avosetta)
Environmental issues simulated
Sea-level rise and shoreline change, plus sensitivity tests changing habitat area and availability time and food quality
Recommendations from modelling
Sea-level rise can reduce avocet survival, but mitigation by creation of non-tidal lagoon can offset this.

Case Study D
Bird species included in model
Bar-tailed godwit (Limosa lapponica), Black-tailed godwit (Limosa limosa), Common redshank (Tringa totanus), Dunlin (Calidris alpina), Eurasian curlew (Numenius arquata), Eurasian oystercatcher (Haematopus ostralegus), Grey plover (Pluvialis squatarola)
Environmental issues simulated
Unspecified driver, sea-level rise and regime shifts changing habitat area, habitat availability time and food quality
Recommendations from modelling
Habitat loss, sea-level rise and changes in invertebrate communities (especially loss of larger prey) can reduce shorebird survival, but effects vary between species.

Case Study E
Bird species included in model
Eurasian oystercatcher (Haematopus ostralegus)
Environmental issues simulated
Shellfishery management changing food density / quality
Recommendations from modelling
Increased shellfishing intensity does not reduce Oystercatcher survival rate.

Case Study F
Bird species included in model
Bar-tailed godwit (Limosa lapponica), Black-tailed godwit (Limosa limosa), Common redshank (Tringa totanus), Dunlin (Calidris alpina), Eurasian curlew (Numenius arquata), Eurasian oystercatcher (Haematopus ostralegus), Grey plover (Pluvialis squatarola)
Environmental issues simulated
Human activity, sea-level rise and prey availability, changing habitat area and availability time and food quality
Recommendations from modelling
Increased disturbance from human activities only reduces shorebird survival if associated with decline in site quality.
