Marine mammal management units in habitat regulations assessments

This document is primarily for:

• Competent authorities conducting habitats regulations assessments (HRAs), including those undertaking transboundary consultation
• Developers and consultants submitting information to allow a competent authority to undertake HRAs

It sets out NRW’s advice on the spatial scale that should be used to determine the Likely Significant Effects of a plan or project on special areas of conservation (SACs) with marine mammal features (a process known as ‘screening’).

Following this advice will ensure that the correct sites, plans and projects are considered at the appropriate assessment stage of Habitats Regulations Assessments.
