Case Study A

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), Ringed plover (Charadrius hiaticula), Turnstone (Arenaria interpres)

Environmental issues simulated

Port development and unspecified driver of prey density. Mitigation due to changing habitat area and food availability

Recommendations from modelling

Port development can decrease shorebird survival, but mitigation by creation of a tidal creek can offset this.

Case Study B

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), Grey plover (Pluvialis squatarola), Ringed plover (Charadrius hiaticula)

Environmental issues simulated

Human activity from increased housing, affecting habitat area, availability time and energy need

Recommendations from modelling

Increased disturbance from human activities, associated with increased housing, can potentially decrease shorebird survival.

Case Study C

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), Grey plover (Pluvialis squatarola), Turnstone (Arenaria interpres)

Environmental issues simulated

Unspecified driver and sea-level rise changing habitat area and habitat availability time

Recommendations from modelling

Habitat loss and sea-level rise can reduce shorebird survival, but effects vary between species.

Strangford Lough

Bird species included in model

Eurasian oystercatcher (Haematopus ostralegus)

Environmental issues simulated

Shellfishery management with extreme weather, changing habitat area, availability time, food quality and energy requirements. Mitigation due to fishing ban.

Recommendations from modelling

Mechanised cockle harvesting has a greater impact on shorebird survival than cockling cockles by hand.

Bird species included in model

Eurasian oystercatcher (Haematopus ostralegus)

Environmental issues simulated

Shellfish food requirements of oystercatchers

Recommendations from modelling

To maintain high oystercatcher overwinter survival, more cockle and mussel food needs to be available when temperature is lower as the birds need to expend additional energy to maintain their body temperature and the rate at which they can consume food from terrestrial habitats can be reduced.
