From the Lawrence Daily Journal-World for March 27, 1986:

Lawrence parks were going to get a little Arbor Day love from some local residents. City workers, with some help from the Cottonwood 4-H Club, were planning to replace trees damaged by vandals in Burcham Park. About 30 “cottonless” cottonwood trees were to be planted to replace the 33 trees that had been broken in half in February. The 4-H club had donated $140 towards the replacements. Replacement cost of one tree was $100. In other tree news, a “Tree City U.S.A.” flag had been raised across from Lawrence City Hall, recognizing that the city had met several conditions, including spending more than $1 per capita on tree care. Lawrence was spending $5 per capita at the time, including tree removal and tree purchases, landscaping and salaries for city landscaping personnel.
