The aquaculture industry is an important economic activity on all coasts of Ireland. A significant proportion of the activity occurs within, or in proximity to, Natura 2000 sites which are designated areas under the EU Habitats and Birds Directives.
Many Natura 2000 sites are designated as Special Protection Areas (SPAs) for wading birds. Such areas, typically inter-tidal mud and sand flats, support nationally and internationally important populations of waders that over-winter in these habitats in Ireland. These bird populations feed on various species of invertebrate that have accumulated in biomass during the summer and early autumn period. Over-wintering survival of wading birds is mainly a question of energetics; availability, access and intake of food must provide sufficient energy to maintain body condition. Significant decline in body condition can lead to mortality or lower reproductive fitness in the following year.
The aquaculture industry in SPAs, designated for wading birds, may have an impact on the fitness and survival of these birds. This could come about due to targeted removal of prey species such as bivalves, by causing mortality of other non-commercial invertebrate prey species that come into contact with aquaculture installations, by alteration of the habitat and the invertebrate communities it supports and by reducing access to food or time available to feed by disturbing flocks of feeding birds.
Article 6 of the Habitats Directive requires that the impact of projects or plans, such as aquaculture enterprises, be appropriately assessed in relation to the feature (habitat, species) for which the site was designated, so that the likelihood of significant effects on the feature can be objectively estimated. Only when the likelihood of significance has been discounted can these activities be licensed in Natura 2000 sites. This project will investigate the interactions between proposed aquaculture activities and Natura features (birds) in a number of SPAs as dictated by the Aquaculture and Foreshore Management Division of DAFM and make recommendations in relation to subsequent licensing and management of aquaculture activities in the sites.
This project is essential to the delivery of aquaculture and Natura services under the PAF and Priority Area 2 of the EMFAF Biodiversity / Aquaculture programme.
Immediate benefits will be realised by the MI in its advisory role as efforts will be strategically focussed in Natura 2000 sites that contain high levels of shellfish aquaculture or that are subject to high volumes of current and/or upcoming shellfish aquaculture licence applications.
