At least 2508 planted in last 11 years (as of Aug 2010) – disease resistant – climate neutral zone. Landscaping updated with native, drought resistant plant species and low maintenance i.e. drought resistant – reduced shrubs and annuals. All campus trees inventoried and mapped as are major annual beds and other landscape assets
This was implemented on campus with the addition of new trees. It is a method of localized irrigation that saves water and fertilizer by dripping water slowly to roots of plants and trees. This is accomplished with the tubing rings shown circling the trees. An emitter controls the water output. These soil patches are probed to ensure the trees have enough moisture. The system is also hooked up for rain shutdown mode. This system is a major improvement from the previous turf sprinkler system used.
This is a system the University is considering installing that can detect rain, humidity, wind speed and other factors in order to determine the precise amount of water needed to sufficiently water the TU grounds. The biggest road block with the weather station is finding a place to install it that meets the station’s requirements.
Pesticides and Fertilizers:
TU only spot sprays for insect problems. When they do spray they use Talstar, which although it is still restricted, it is a major improvement to previously used organophosphates. The employees using the spray are careful when applying it to minimize potential runoff or overuse. The University has also gone with a fertilizer with a longer residual that only needs to be applied twice a year.
TU uses Diesel and mulching mowers which have low emissions. TU has also invested in two low emission blowers and two low emission weed eaters, although these products do not have the power the university would like to see, they are at least willing to experiment and invest in the equipment.
