Sources: Assessment Units GIS data provided by the National Oceanic and Atmospheric Administration.

Pies and Charts: Pies and bars were generated from estimates of the habitat condition of key limiting factors associated with habitat actions planned to be completed for the FCRPS BiOp through 2012. The pies and bars only represent conditions for the term of the FCRPS BiOp (2007-2018), do not include conditions associated with habitat actions completed by other parties within this time period, and, therefore, may not represent the status of these key limiting factors for other than FCRPS BiOp purposes.

Details: Stacked bars and values of Overall Function (%) represent differences between functioning (green) and non-fully-functioning (red) key limiting factors aggregated for each assessment unit.Size of each pie is relative to the Intrinsic Potential of each Assessment Unit within the population as defined for Recovery Plans by the Interior Columbia Basin Technical Recovery Team. The interinsic potential weighting factor (Watershed Weight) is denoted below each pie.Pie slices and values indicate the relative proportion of each limiting factor that comprise the non-fully-functioning (red) part of the bar. Zero values indicate a limiting factor was identified for FCRPS BiOp purposes, but habitat condition values have not yet been assigned.
