Bahía de Cadíz

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.

Dungarvan Harbour

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), Red knot (Calidris canutus), Ringed plover (Charadrius hiaticula), Sanderling (Calidris alba)

Environmental issues simulated

Effects on birds of habitat loss and disturbance due to oyster cultivation.

Recomendations from modelling

Current extent of oyster cultivation not predicted to be affecting survival of priority bird species. Increases in extent of oyster cultivation likely to push system closer to the point at which a predicted effect on the birds would occur.

Humber Estuary

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), Red knot (Calidris canutus), Ringed plover (Charadrius hiaticula)

Environmental issues simulated

Port development and sea-level rise changing habitat area and habitat availability time

Recommendations from modelling

Sea-level rise and port development can reduce shorebird survival if feeding conditions poor.

Case Study B

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), Red knot (Calidris canutus), Sanderling (Calidris alba), 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.

Case Study C

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), Red knot (Calidris canutus), Ringed plover (Charadrius hiaticula), Turnstone (Arenaria interpres), Sanderling (Calidris alba)

Environmental issues simulated

Intertidal habitat creation

Recommendations from modelling

Increasing the area of intertidal habitat by the creation of a coastline managed realignment site can increase the number of birds supported.
