Sandhill Cranes breed in open marshes, bogs, wet grasslands, and meadows, which makes the Looking Glass River Corridor a great location for these magnificent birds. Their nests are usually low mounds built out of dominant vegetation and typically located in wetlands. The birds typically migrate south for the winter and return to areas like A Looking Glass in spring.

A Looking Glass Sanctuary, a 13.63-acre sanctuary, derives its name from the Looking Glass River, which flows along the east boundary of the sanctuary, and was deeded to Michigan Nature Association MNA) in 2006 by the Fellowship for Today Church in East Lansing.  

The property was previously owned by Denise Wootton, a prominent member of the Fellowship. Historically, though, this stretch of river was part of a transportation and camp network used by Native Americans. Denise and her husband, Jim, bought 48 acres along the Looking Glass River in 1995. When Jim passed away in 2005, Denise sold two parcels of the property. The Fellowship bought the southernmost 13 acres, and for a time, its members considered maintaining the land as a sanctuary themselves. It was eventually decided that MNA was better suited to protecting the peaceful sanctuary in perpetuity.

A Looking Glass Sanctuary is mostly old-field, but also contains a floodplain forest, wetland, and a dry-mesic southern forest. The sanctuary functions primarily as a floodplain and provides an area for flood waters when the Looking Glass River overtops the banks during periods of high flow. These flood cycles deposit sediment, nutrients, and pollutants in the floodplain, where they can then be absorbed by plants, which utilize the nutrients and neutralize the pollutants. The seasonally flooded vegetation also creates an excellent spawning habitat for fish species such as northern pike.
