Table 4/Amber (Wintering population)
Biodiversity Steering Group
Conservation Concern List

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 wintering populations (augmented by Icelandic and Arctic breeders) are stable, The BBS suggests that UK abundance and especially Scottish abundance is currently in decline..
