INTRODUCTION 1.1 Background This report has been prepared by Dr. Brian Madden of BioSphere Environmental Services, in association with ESB International, to determine the potential impacts, if any, of the plan for the Oweninny Wind Farm on nearby sites with European conservation designations (i.e. Natura 2000 sites). The purpose of this assessment is to determine, the appropriateness, or otherwise, of the proposed project in the context of the conservation objectives of such sites. The report is based on desk review and extensive site surveys carried out between 2010 and 2013. 1.2 Regulatory Context The Council Directive 92/43/EEC on the Conservation of Natural Habitats and of Wild Flora and Fauna better known as “The Habitats Directive” provides the framework for legal protection for habitats and species of European importance. Articles 3 to 9 provide the legislative means to protect habitats and species of Community interest through the establishment and conservation of an EU-wide network of sites known as Natura 2000. These are Special Areas of Conservation (SACs) designated under the Habitats Directive and Special Protection Areas (SPAs) designated under the Conservation of Wild Birds Directive (79/409/EEC) (better known as “The Birds Directive”). Article 6(3) and 6(4) of the Habitats Directive set out the decision-making tests for plans and projects likely to affect Natura 2000 sites (Annex 1.1). Article 6(3) establishes the requirement for Appropriate Assessment (now termed Natura Impact Statement – see The Guidance for Planning Authorities issued by Department of Environment, Heritage and Local Government, December 2009): “Any plan or project not directly connected with or necessary to the management of the [Natura 2000] site but likely to have a significant effect thereon, either individually or in combination with other plans and projects, shall be subjected to appropriate assessment of its implications for the site in view of the site’s conservation objectives. In light of the conclusions of the assessment of the implication for the site and subject to the provisions of paragraph 4, the competent national authorities shall agree to the plan or project only after having ascertained that it will not adversely affect the integrity of the site concerned and, if appropriate, after having obtained the opinion of the general public” 5 ESB International Biosphere Environmental Services Oweninny Wind Farm Natura Impact Statement The Habitats Directive promotes a hierarchy of avoidance,
