Circle B Bar Reserve

Named after a cattle ranch that once existed on this property, Circle B Bar Reserve was jointly acquired by the Polk County Environmental Lands Program and the District to protect the floodplain of Lake Hancock and to restore the Banana Creek marsh system. The property is maintained by Polk County. Much of the property had previously been converted to pasture, but in 2005 and 2006, restoration projects were completed to restore much of the original hydrologic function of the lands. As a result of the marsh system restoration project, Circle B is now home to some of the most impressive bird activity on District property. The tremendous bird population includes a variety of wading birds, waterfowl, ospreys and bald eagles. Alligators inhabit Lake Hancock and may be observed at a distance from shore or from a pier. Oak hammock, freshwater marsh, hardwood swamp and the lakeshore are among the unique characteristics of this property.

Polk County Nature Discovery Center

In November 2008, construction of the Polk County Nature Discovery Center was completed. Managed by the Polk County Natural Resources Department, the center provides educational opportunities for Polk County public schools and is open to the public. There are exhibits in the center that display environmental and hydrologic functions of Florida's natural resources. Nature trail, pavilion and information signs are available for public use on the grounds adjacent to the center.
