Data collected as part of the BTO/RSPB/JNCC/WWT national Wetland Bird Survey scheme (WeBS) have been obtained for the same sectors as those surveyed in winter 2011/12 in order to put the winter 2011/12 survey data into context. For core count sectors, data were requested for the most recent five years available. At the time of request, 2009/10 data were the most recently available and therefore counts extend back as far as 2005/06. For the low tide sectors, data were requested for the most recent winter that each sector was surveyed. In the case of Sectors BX001, BX002 and BX003, these were last surveyed by WeBS in winter 1998/99, whilst Sectors BX004, BX005 and BX019 were last surveyed in winter 2006/07.
