Abstract
This document represents the deliverable for work package 3 (WP3) of the ORJIP/Carbon Trust project entitled Improving Understanding of Distributional Change for Relevant Seabird Species (ImpUDis). This project consists of several work-packages, and project goals relevant to work package are:
- Establish agreed methods and sources of evidence to help improve consistency in future assessments and approaches to post-consent monitoring.
- Improve our understanding of seabird distributional change by developing, and applying, standard statistical methods.
This report builds upon initial work within the project, which included:
- WP1 - A comprehensive literature review of studies into the redistribution of seabirds in relation to offshore wind farm (OWF) development (Murrell et al., 2025).
- WP1 - Identification and acquisition of data within these studies, and other OWF developments within UK waters.
- WP2 - A guidance document for analysis of such data for estimating seabird redistribution in response to OWF developments.
- WP2 - An analysis plan for existing data, and associated stage-gate meeting.
This report presents the results of analysis of extant data identified at the stage-gate meeting, using the WP2 analysis plan. This consists of the data obtained under WP1 and deemed usable for estimation of redistribution, following their examination in conjunction with the WP2 guidance. The analyses here also served to inform the WP2 guidance document, offer practical advice, and address research questions confirmed at the stage-gate meeting.
