Shellfish Stocks, Oystercatcher and Knot (bird) Modelling Data for the Burry Inlet and Three Rivers (2004-2007)

The Burry Inlet Special Protection Area (SPA) supports nationally and internationally important populations of wildfowl and waders which feed on the mudflats and sandflats over the winter period. Oystercatcher feed predominantly on cockles, and knot feed on a range of prey including cockle spat. CCW commissioned a series of studies to determine the food requirements of oystercatcher and knot, to develop conservation objectives, monitoring targets and to assess the implications of cockle and mussel fishing scenarios on the bird populations. The latest of which is published as CCW Marine Monitoring Report no. 65. The purpose of this project was to extend previous modelling to incorporate both the Burry Inlet and Three Rivers in order to determine the inter-reliance of the sites and how environmental change (e.g. changes in shellfishing, habitat loss, changes in human disturbance, climate change and changes in population size) affects foraging animal populations. This information will be used to help inform management of the SPA.

Predicting the effect of shellfish stocks on the oystercatcher and knot populations of the Burry Inlet and Three Rivers

Metadata Language: English

Lineage: An individual behaviour-based model (IBM) is used to predict the food requirements of a bird population. The model requires information on bird foraging behaviour together with site-specific data on bird numbers, and the size and distribution of cockle and mussel stocks. The following datasets were collated for the model. 1. Bird population size in the Burry Inlet and Three Rivers 2. Long-term shellfish stocks in the Burry Inlet 3. Detailed shellfish stock estimates in the Burry Inlet and Three Rivers 4. Identification of cockle patches in the Burry Inlet and Three Rivers 5. Shellfish removed by shellfishing in the Burry Inlet and Three Rivers This data was collected under different projects. The methodologies on how this data was collected is available elsewhere (e.g. Moore, 2009, Banks et al., 2007) The latest version of the model MORPH is used. MORPH tracks the foraging location, body condition and ultimate fate of each individual within an animal population. The modelled data builds on work carried out by Centre for Ecology and Hydrology (Dorset) that modelled shellfish stocks, oystercatch and knot for the Dee Estuary, Traeth Lafan and Burry Inlet in. Previous data is archived in project 158 (media no 103 and 486). This work is now undertaken by Bournemouth University.
