Declining survival of ring-necked pheasant chicks in Illinois during the late 1900s
Article Abstract:
Studies of ring-necked pheasant chicks show that survival rates during the first six weeks of life fell from the early 1950s to the early 1980s in Illinois, probably because of expanded soybean and corn production. Land-use practices of the 1980s and 1990s have been moderated by farm programs and large areas of cropland have been removed from production. A new study evaluates whether the changes in farming practice have benefitted survival rates of ring-neck pheasant chicks. It is shown that chick survival rates remained low between 1982 and 1996 despite a slight increase in the number of chicks per brood. It is thought that clean farming practices may account for the lack of improvement.

A regional model of the eastern cottontail and land use changes in Illinois
Article Abstract:
The eastern cottontail is a prey species and game animal, and it has seen a population decline which is linked to changes in land use since 1945, with a rise in intensive grain production and a decline in rotation farming. Woodland, hay and pasture are more common in areas of Illinois where the cottontail population has declined least. Topography is important in that flat areas are more likely to be used for intensive farming. Multiple habitats can play a role in indicating the abundance of a species.
