The solution to this invasive issue ultimately lies in the hands of homeowners, landscapers and developers. Please consider one of the many non-invasive alternatives to Callery pear trees when undertaking new landscape projects or large community developments. A decrease in the number of Callery pear cultivars and hybrids would be beneficial for our entire community to potentially reduce power outages, save costs of trimming and tree removal, and create a more ecologically balanced community forest.

Educational brochures and posters for the “Stop the spread!” campaign are available at the Parks Management Center, 1507 Bus. Loop 70W, Columbia, Missouri. Contact 573-874-7201 to make arrangements to pick up a poster.
