Additional activities involved 0.75 mile of fence-building and 5*5 hours of 
bulldozing ditches and junk heaps. Most of the activities listed were accomplished 
through share agreements with local farmers or through contractual services. Net 
income from seed harvests, crops, hay, and grazing fees amounted to $15*741.04 
for the Prairie Grouse Committee of the Illinois Chapter, The Nature Conservancy, 
which owns or leases 894 acres, and $2,928.90 for the Illinois State Treasurer 
from 567 acres owned by the Illinois Department of Conservation and dedicated as 
Illinois Nature Preserves. 
Costs of management activities to both owners, including real estate taxes 
paid by the Prairie Grouse Committee, were well below the amounts of income. 
Thus, sanctuary management for prairie chickens is essentially a self-sustaining 
operation. Also, much of the management that is essential for prairie chickens 
can also produce food and fiber for people. From this standpoint prairie chicken 
management is unique, and this aspect is likely to become more important because 
of the mounting pressures of an increasing human population.
