Burry Inlet
Case Study A
Bird species included in model
Eurasian oystercatcher (Haematopus ostralegus)
Environmental issues simulated
Cold winter conditions increasing energy requirements, plus shellfishery management changing habitat area, habitat availability time, food quality.
Recommendations from modelling
Current shellfishing intensity does not reduce shorebird survival, but reduced fishable size or increased daily quota could.

Case Study B
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.
