A plaque and small playground referred to as the "Little Treehouse on the Prairie" was erected in Knight Park, a central park in Landon's hometown of Collingswood. In 2011, the plaque was removed from the park by the borough and was later given to a local newspaper by an unnamed person. According to the Collingswood, NJ website, the plaque was removed during a fall cleanup with plans to return it to a safer location. The plaque was reinstated next to a bench in a safer location the following summer.
