The presentation at ESO2010 surveyed species abundances at all 3 localities 1997-2001 and 2001-2007, and at Jokers Hill 2001-2008. The presentation used only two graphs of named species abundances pooled across locality, supplemented by numerical measures of species abundance and ecological similarity across the years. There were clear trends in the abundances of the various farmed species, with two originally common species groups being greatly reduced (e.g., Hylaeus and Passaloecus), and no species yet completely lost.

This collection adds preliminary work not included in the talk. There is one set of simple abundance plots for each locality. Each set consists of 4 plots: (A) the few dominant species; (B) the few other numerous but perhaps less consistent species; (Ci) many generally sparse species that may not always be present; (Cii) same abundances as Ci but using species abbreviations instead of names so as to the reduce visual clutter of the histograms. These plots give a convenient overview without making an allowance for occasional changes in the numbers of nest cavities offered.
