The purpose of this study was to demonstrate the
value of urban areas to protecting biodiversity. A common misconception is
that urban areas and biodiversity are mutually exclusive. The scope of
this paper was to identify what types of animals make use of residential
areas and the attributes that promote or discourage their survival.
Twenty-seven diverse residential sites in six different counties of the
greater Chicago region were selected to evaluate the features valuable to
wildlife. A mix of older and newer developments, some actively promoting
the environment, was chosen as part of the study. Residential housing
densities ranged from 0.2 to 13.6 units per acre, and sites near Illinois
Nature Preserves were favored to increase the likelihood of observing
animals.
