Coverage

Survey tetrads (2x2km) will be chosen based on a stratified random design from across their range, based on:

  • non-random, self-selected squares in core areas, mostly around existing monitoring/intervention efforts,
  • random sampling of occupied tetrads, from 2007-11 Atlas and later (high intensity),
  • random sampling of remaining tetrads in occupied 10km squares, from 2007-11 Atlas and later (medium intensity), and
  • lower intensity sampling through the rest of the known range, from the 1988-91 Atlas.

Data from the 1988-91 and 2007-11 bird atlases, recent county atlases and from the RBBP are being used to identify the areas of sampling intensity.
