The second restoration site established under the Kansas River and Missouri River Wetland and Stream Umbrella Mitigation Bank, this 199-acre mitigation site along Stranger Creek compensates for authorized impacts to wetlands and streams across most of northeastern Kansas.

Because this restoration site protects more than a mile of Stranger Creek on one side, Swallowtail has the opportunity to improve water quality and wildlife habitat in a watershed that is heavily impacted by agriculture.  Historically, the habitat at the site would have consisted primarily of riparian forest with a mixture of forested, scrub-shrub, marsh, and wet prairie wetlands.  The location was altered for agriculture by removing almost all of the riparian forests and converting the other habitats to row crop fields.  A levee was built along the entire length of Stranger Creek which limited flooding of the site, and Brush Creek, a significant perennial tributary of Stranger Creek, was channelized and realigned.  A small ephemeral stream was also impacted and became incised.
