Total campus area:
229.73 Acres

Figures required to calculate the total area of managed grounds:
Area (double-counting is not allowed)
Area managed organically, without the use of inorganic fertilizers and chemical pesticides, fungicides and herbicides 2 Acres
Area managed in accordance with an Integrated Pest Management (IPM) program that uses selected chemicals only when needed 227.73 Acres
Area managed using conventional, chemical-based landscape management practices 0 Acres
Total area of managed grounds 229.73 Acres

A brief description of any land excluded from the area of managed grounds:

Total area of managed grounds includes all turf, landscape beds, sidewalks, and parking lots managed by the Campus Services Department. This number excludes the footprint of all buildings operated by the university within areas that are maintained by the Campus Services Department. The University utilizes an IPM procedure wherein inorganic chemicals are utilized once a semester, with all other applications being of organic origin.


Percentage of grounds managed organically:
0.87

A brief description of the organic landscape management program:

2 locations on campus have been identified as organic management areas; pollinator garden and FAC Slopes. These areas have limited use pesticides in these areas, are integrated with IPM and have manual removal of undesirable plants.


Percentage of grounds managed in accordance with an IPM program:
99.13

A brief description of the institution's approach to plant stewardship:

In the past several years, the university has developed a plant stewardship program to help protect existing vegetation from erosion. We have achieved this through by raising the height of cut on all turf areas on the university to help with a thicker, denser turf. This has helped decrease soil erosion and limited weed germination within the turf areas.
The department has made a strong commitment to control and manage invasive species through establishing a strong health turf to keep invasive species out of the turf areas, while manually removing invasive plants from our landscape beds.


A brief description of the institution's approach to hydrology and water use:

The university's approach to hydrology and water use has been to reduce the amount of irrigation water and use more natural water sources. The university has increased "Green space" across campus to help with storm water filtration into the soil. Smart irrigation systems are installed across the university to reduce the amount of irrigation water used. The system only runs when humidity and temperature levels are ideal for water filtration by plants and turf.


A brief description of the institution's approach to landscape materials management and waste minimization:

All WKU's tree waste is taken to the WKU Farm to be ground and incorporated into mulch operations. Additionally, all leaves collected from campus are taken to the WKU Farm to be incorporated into composting or leaf mulch operations. Finished compost is used by the university or sold to the community to fund scholarships.


A brief description of the institution's approach to energy-efficient landscape design:

"Smart Water" irrigation systems have been installed through the university to help reduce the demand for city feed water during dry summer months. Irrigation rain barrels have been installed to capture rain water, which is stored and reused to water annual beds throughout the university.

Outdoor lighting within landscape beds have been transferred to low-wattage LED bulbs. Evergreens have been planted along the east in-zone of the football stadium to provide a windbreak for the football field. WKU is continuing to explore multifunction landscape design.


A brief description of other sustainable landscape management practices employed by the institution:

WKU has moved toward using less calcium chloride and more Cryotech CMA® solid commercial deicer. This is granulated calcium magnesium acetate, a patented chemical formulation from dolomitic lime and acetic acid. It is identified as a low corrosion, environmental alternative to road salt by the U.S. Federal Highway Administration. CMA is used worldwide to answer environmental concerns such as pollution, soil contamination from heavy salts and solve problems associated with corrosion and concrete spalling.

Data source(s) and notes about the submission:

Please note the most recently available grounds maintenance map attached is from 2020, but is still mostly accurate. Some buildings have been removed (Garrett Conference Center transformed to green space; Tate Page Hall) and one constructed on main campus, to total 165 acres of managed grounds on main campus, excluding the footprint of buildings.
