the fiveroutes be run separately but concurrently by both new and old observers 

 in June, to allow correlation between the two. Depending on the exact location 

 of the plant site, housing areas, and transportation corridors, one or more of 

 the routes (including the Dreyer Ranch route) will serve as experimental repli- 

 cates, and the remaining routes will serve as controls. The theoretical total 

 number of species (S^) should be determined for cumulative sample abundance 

 distributions as breeding-season (May-July) data are pooled for (1) each route, 

 and (2) the five routes combined. It is also suggested that each, year the aver- 

 age May-July values for species number, species richness, species diversity, and 

 sample abundances of each indicator species be plotted as in figure 53-A, in 

 order to graphically portray the nature and magnitude of year-to-year fluctuations, 

 The relative positions of the five routes on these graphs are likely to remain 

 unchanged for all or most of these parameters, except for the experimental routes 

 following disturbance (figure 53-B). The eventual restoration of the original 

 ordination of ttie five routes should provide substantial evidence for the success 

 of reclamation (figure 53-C). 



Breeding Bird Census 



In 1978, during the year immediately prior to mining, and during alternate 

 years thereafter until reclamation is complete, censuses should be taken of the 

 five breeding bird census grids established in the baseline study using standard 

 methods. This will allow comparison of experimental and control grids in terms 

 of species density and diversity.
