Manipulation of pheasant Habitat G. B. Joselyn 
In 1972, the first search for pheasant nests on seeded and on managed 
control plots along 8 miles of roadway on and near the Sibley Study Area was 
conducted during the period June 22-27. Forty-seven nests were located on 
the plots, 30 on seeded and 17 on managed control plots. These totals 
represent declines in nest abundance of approximately 35 percent on seeded 
plots and approximately 45 percent on managed control plots, compared with the 
totals for the first search in 1971 on the same 8 miles of roadway—46 nests 
on seeded plots and 31 nests on managed control plots.
