Long term trend
UK: Moderate decline
 
Status Summary
Geographical biases mean that Redshank were not monitored well by BTO surveys before the advent of the BBS, but considerable range contraction has occurred from many areas of the UK, probably as a result of the drainage of farmland (Gibbons et al. 1993). Although WBS data suggests that numbers have declined since the mid-1970s, wintering populations (augmented by Icelandic and Arctic breeders) are stable (Musgrove et al. 2001) and the BBS shows no clear trend in abundance over the last six years. The substantial section of the British population that nests on saltmarshes decreased by 23% between 1985 and 1996 (Brindley et al. 1998).
