Appropriate Assessment

An appropriate assessment (AA) is an assessment of the potential adverse effects of a plan or project (in combination with other plans or projects) on Special Areas of Conservation and Special Protection Areas. These sites are protected by National and European Law.

Our AA GeoTool application helps with the data gathering process of Stage 1 and Stage 2 Appropriate Assessment. The Environmental Protection Agency (EPA) and the National Parks and Wildlife Service (NPWS) have worked together to develop the AA GeoTool.

The application uses data directly from a web service provided by the NPWS. The data is current and the assessments are based on the most up-to-date information available.

The AA GeoTool allows the user to select a point on the map and then search for SACs and SPAs within a defined distance/ upstream/ downstream of the point. The distance selected by the user is dependent on the level of potential environmental impact from a plan or project. The information gathered for each European Site located within the selected distance range includes the following:

For instructions on how to use the tool please refer to the User guide, accessible through the Help button in the application or directly here

Further information on specific European Sites can be found on the NPWS website.

The Northern Ireland European Sites are not currently included in this application. For more information on the Northern Ireland European Sites please consult the Northern Ireland Department of Agriculture, Environment and Rural Affairs website.

The requirement for "Appropriate Assessment" is set out in Articles 6(3) and 6(4) of the Habitats Directive (92/43/EEC). The Habitats Directive is transposed into Irish law by the European Communities (Birds and Natural Habitats) Regulations 2011 as amended (hereafter referred to as the Habitats Regulations).

European Sites are defined in Regulation 2(1) of the Habitats Regulations and comprise Special Areas of Conservation (SACs) and Special Protection Areas (SPAs), at all stages of designation commencing with the Minister's notice of intention to designate. Regulation 42 of the Habitats Regulations requires the EPA to undertake Stage 1 Screening for Appropriate Assessment (AA) and where necessary Stage 2 Appropriate Assessment of any plan or project for which an application for consent is received.


The AA GeoTool is a data gathering tool only and does not intend to replace the assessment element of any part of the AA process. Whilst every effort is made to ensure the accuracy of the information provided by the AA GeoTool, it is not possible to guarantee that it is accurate in all cases. Accordingly, whenever accuracy is important, it is recommended that you obtain a copy of the original documentation on which the information is based and verify its accuracy.
