The Wash is England’s largest Special Protection Area, with Oystercatchers being a designated feature. During the winter, Oystercatchers rely heavily on Cockles and Blue Mussels for their food requirements, creating the potential for conflict with the human fisheries for these species.

The Seabird Monitoring Programme, funded by the British Trust for Ornithology and Joint Nature Conservation Committee (JNCC), in association with the Royal Society for the Protection of Birds, aims to ensure that sample data on seabird breeding numbers and breeding productivity are collected both regionally and nationally, for 25 species of seabird that regularly breed in Britain and Ireland, to enable their conservation status to be assessed.

The Welsh Red Kite population is currently in ongoing recovery after a historic decline driven by persecution, and a consequent population bottleneck during the first half of the 20th century. Trends from the BTO/JNCC/RSPB Breeding Bird Survey show that the population has grown rapidly over the past few decades. Nonetheless, the Red Kite remains a conservation concern, in particular around two Special Protection Areas (SPAs) designated for the species’ conservation: the Berwyn SPA and the Elenydd—Mallaen SPA. Wind turbines represent a known threat to Red Kite populations, causing additional mortality through collisions. A large number of wind farm sites are currently at various stages of development (ranging from aspirational schemes to proposals under assessment) in Wales, especially in Mid Wales where Red Kites are at their highest density and where the Elenydd-Mallaen SPA is situated. The aim of this analysis is to model the potential impacts of current and proposed wind farm developments on the Welsh population of Red Kites, using a Population Viability Analysis.
