Birds of Conservation Concern 4 (BOCC4), commonly known as the UK Red List for birds was published in December 2015, updating the third review published in 2009. Standardised criteria have been used by experts from a range of leading bird NGOs to reassign 244 of the 247 bird species assessed, to either the Red, Amber or Green lists of conservation concern.
Overall, there has been an increase in red-listed species, many of which are found within woodland and upland habitats, with more species being red-listed than on any of the previous versions of the BoCC. Several species were also moved onto the green list, with an overall reduction in the number of species on the amber list. More details on the process can be found here.
We will use these new lists in place of those previously published to inform ecological valuation where necessary as part of the impact assessment process. Our clients can therefore be confident that our conclusions and recommendations continue to be based on the most up-to-date information available in line with best practice.
