Comments:
Appendix D, Table D-2, given as population data for "Other sites S. ID 1993" is 330 nests, 660 area population estimate (nests x 2), population data source is Trost and Gerstell 1994. However, Trost and Gerstell 1994 states the total range of 242 to 360 Western grebe nests so I'm not sure how it is 330 nests in Appendix D, Table D-2 of the IWWCP. Subtracting Minidoka NWR's # nest estimate for 1993 doesn't equal 330 nests.
