Tree Inspections Periodic inspections of each campus's tree resources is critical in providing preventative measures to combat natural and man-made injuries, growth and cultural abnormalities and pest and disease control needs.

Assuming that grounds maintenance personnel who are around the trees all the time will “notice when something is happening" does not replace the fact that a physical inspection of plant resources is needed periodically. Pest Control Needs: Insect infestations can occur at any time or may be predictable dependent on a particular species or plant vigor. The "Seasonal Inspections" section under the "Annual Inspections" tab defines the frequency of these inspections to insure that insect infestations do not create adverse impacts on plant resources. Insect infestations that should be noted and a spray plan established for include but may not be limited to the following target pests: borers, beetles, mites, bag worms, web worms, scale, wasps, and bees. Other problems that should be identified include cankers, galls, and weeping plant tissue, all of which may or may not affect the target plant, but may be the host or entry point for other diseases or issues that affect other plant species. Man-made Injury Repair: Man-made injuries may occur at any time and if left unattended, may lead to significant deterioration of tree resources. The damage to trees may result from construction activities, mowing operations, trimming, or by vehicle operators who do not use caution when parking vehicles in parking lots near trees. Depending on the nature of tree wounds, damage from the careless operation of mowers and weed eaters should be reported to the contract administrator so that an appropriate TCC – Southeast Campus Tree Care Plan Goals

The Southeast Campus Tree Care Plan applies to the 68 acres of land South of E. 81st St. and west of highway 169 in Tulsa, Oklahoma.

1. Obtain a diversity of trees in terms of age and species at the campus.

2. Plant a sufficient number of trees in the next 10 years to eventually increase existing

canopy of tree coverage at the campus by 20%.

3. Educate the campus as to the tree inventory through an identification system that the College will make available to faculty, students, staff, and visitors.

4. Maintain and protect campus trees as is prudent from man-made and naturally-

occurring hazards.

5. Involve TCC biological sciences students in the care and maintenance of the campus tree inventory.
