The Conservation Reserve Program:
Habitat for Grassland Birds
General Results
Seventy-three species of birds were detected within the CRP fields during the three years. Average densities (pairs per 100 ha) ranged around 100-150, but were lower in the western counties of Fallen (MT) and Butte (SD) (Table 1). A listing by species and year is given in Table 4 for species with a total count of at least five. Table 5 gives densities, by County and Conservation Practice, for 12 of the most common species, for which we developed statistical models.
