Conservation listings

Europe (C. cabaret/flammea): no SPEC category, (secure)
UK: Amber (>50% population decline but data possibly unrepresentative, >20% of European breeding population)

Long-term trend
England: rapid decline
Status summary
Lesser Redpolls were once abundant and widespread on CBC and CES plots in lowland Britain, but are largely absent now as breeding birds. The 1988-91 Atlas showed a range contraction of 11% since 1968-72, including complete loss in much of eastern Grampian (Gibbons et al. 1993). It is nevertheless possible that they may have withdrawn from the lowlands to northern and western UK regions, where monitoring prior to 1994 was less effective. The species has been moved from the Green to the Amber list, although the apparent extent of its decline clearly warrants Red-listing. It is unclear from BBS results whether the decline has ceased, and some recent increase is indicated in Scotland. CES data indicates a rapid long-term decline in productivity, and there is evidence that survival rates also fell during the population decline (Siriwardena et al. 1998a). Since C. cabaret is now treated as a separate species from C. flammea, and has a restricted range that lies wholly within western Europe, it is likely to gain a European conservation listing at the next review.
