students planting trees

College student volunteers dig a hole on the Arch grounds, to plant one of twenty-four trees in the park.


The trees were being funded by the Missouri Department of Conservation, through a
T.R.I.M. (Tree Resource Improvement & Maintenance) $10,000.00 matching funds grant. The trees were being planted to replace trees that had been removed due to storm damage or disease.

The students were under the supervision of Deborah Hyland, English instructor from the college, and Jim Jacobs, park grounds maintenance Gardner Supervisor, as well as park grounds maintenance personnel.
