[2] The village of Libertyville is part of the township, as are parts of Green Oaks, Lake Bluff, Lake Forest, Mettawa, Mundelein, North Chicago, Rondout, Vernon Hills and Waukegan.

The stream of Bull Creek runs through this township, before depositing into the Des Plaines River.

This innovative land protection program was funded by a 22.6 million-dollar bond referendum approved by the residents of Libertyville Township.

Since land acquisition began in 1986, over 1,500 acres (6.1 km2) of irreplaceable open space have been protected with these funds.

Two of these sites, Oak Openings and Liberty Prairie, have also received the state's highest protection status as Illinois Nature Preserves.
