New model for managing coastal bird diversity
Many human activities can cause harm to coastal bird diversity. Therefore behaviour-based population models have been created that can be quickly applied in situations where management decision are necessary. The models can be applied at one or more local sites as well as used to guide European wide policy. A literature review and fieldwork in five sites were conducted, including a wide range of human activities. Furthermore, single site (no emigration) and multi-site (with between site movement) models were parameterised and tested. The models' utility was shown through effect simulation in both local and European policy options. Bird body condition, mortality rate and population size were parameters used in the models. One of the major scientific advances of the project is the newly developed individual-based model. This model has several advantages over the initial models. Since it is more flexible, it can be adapted to a broader range of environmental concerns. Employing one model for both geese and waders brought forth the similarities rather than the differences across systems. Furthermore, since the new model is designed in a more general way and not only restricted to waders and geese, it has an increased potential application of its use in the future.
