This is a 'grand' overview in the sense that it summarizes nest counts across all localities, stands and generations. Because the data are pooled it is also a very narrow view which ignores spatial position, the numbers of immatures in individual nests at the various stages of nest development, their parasitoids and causes of death, and other major nest events recorded in the SOURCE spreadsheets.

The introductory page deals with the progressive implementations of the Data Set project at the three localities over the period 1997-2000. As already noted, the three localities actually formed three differently engineered species communities because, even though the species were regional rather than endemics, there is a species selection imposed by the different mixes of cavity width at each locality. The remainder of the workbook summarizes nest starts, deaths, harvests, 'non-nests' (imperfect constructions), nests with associates and nests with unwintered emergences ---as nest counts across species or across cavity width for each locality or all localities pooled. Total cavities and unoccupied cavities are also given.

Since this work was done a few SOURCE file errors have been found and corrected. The varied analyses of 11.09 are more recent.
