Details

This report comprises a strategic level review of the issues surrounding potential habitat creation mitigation and compensation measures for SPA waterbirds affected by tidal power development on the Severn Estuary. In particular, we compare the likely effectiveness of providing compensatory habitat at a distance from the Severn Estuary to the effectiveness of creating new habitats within or adjacent to the estuary.

Waterbird species that regularly occur on the Severn Estuary were divided into six species guilds based on habitat use and feeding preferences. A range of life-history parameters that may influence the effectiveness of mitigation and compensation measures for each species was gathered from the available literature. These traits were used to inform a range of issues relating to potential mitigation and compensation measures.
