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 | 0.16 Acres |
| Area managed in accordance with an Integrated Pest Management (IPM) program that uses selected chemicals only when needed | 417.61 Acres |
| Area managed using conventional, chemical-based landscape management practices | 0 Acres |
| Total area of managed grounds | 417.77 Acres |
If the total area of managed grounds is less than the total campus area, provide:
Areas that are not regularly managed or maintained include the footprint of buildings and impervious surfaces.
Organic program
0.04
If reporting an organic program, provide:
For the 1 acre of land grown organically (Price Garden), organic compost and mulch is used and IPM is practiced rather than applying inorganic fertilizers and chemical pesticides. The produce is this garden is utilized in the adjacent Rancher's Club restaurant.

A brief description of the IPM program:
IPM is practiced in various components and interdisciplinary programs across campus. Physical Plant Services primarily practices IPM in its greenhouse production through 1) pest identification and routine scouting, 2) mechanical monitoring and trapping, 3) natural/organic treatment, and 4) chemical treatment as a last resort with the lowest toxicity available pending pest outbreak. IPM is practiced both in greenhouse production and outdoors.
Optional Fields
OSU has a Landscape Master Plan that emphases tree preservation and protection. Environmental site review is always the first step of all landscape designs and installations. The proper plants are then chosen for the site with many being native plants. OSU does occasionally use non-native species in some gardens, but does not introduce invasive species in its landscape projects. .
A brief description of the institution's approach to hydrology and water use:
In the year 2018, our Campus forest which is composed of 3,841 trees captured 573.6 cubic feet of runoff in 2018. Our aeration maintenance program loosens compacted soils for better water infiltration. Mulching practices and sod grass areas also help to capture water runoff, increase water filtration, retention, and absorption. The Student Union Plaza, Monroe Street (one of the main thoroughfares through campus), and other hardscapes are permeable. Lastly, we start each new design with information gathered from our campus surveyor to study and understand topography and water runoff for each site to make as little of an impact as possible implementing appropriate planting design and stormwater standards on a case by case basis.
A brief description of the institution's approach to landscape materials management and waste minimization:
OSU has been composting landscape/greenhouse waste materials along with cured horse manure (from the OSU Rodeo Club) since 2011. All of the resulting compost is then used on campus in landscape renovation planting beds and as mulch. Other than a few specialty mulch items (e.g. cottonseed hulls), we no longer purchase ready-to-use compost or mulch. We chip tree pruning's to use as mulch and purchase chipped hardwood scrap from a nearby milling operation to use as bulk mulch (e.g. cottonseed hulls, slope erosion specialty mulch). Dairy Cow dehydrated manure pellets are added quarterly beginning in 2018.
A brief description of the institution's approach to energy-efficient landscape design:
We intend to increase our tree canopy by 10% over the next 10 years. Increased canopy coverage will help with reflective heat and improve shade coverage. We are currently 4.9% canopy coverage. In 2021, we calculated our total tree structural value at $8,606,091.95 and total leaf area of 7,840,800 square feet.
A brief description of other sustainable landscape management practices employed by the institution:
OSU’s sustainable landscape management program approach emphasizes 1) tree care and preservation as a priority, 2) low maintenance site specific landscape design and installation, 3) organic soil improvements and mulching, and 4) balanced fertilizer, pest control and irrigation practices. A stringent tree care plan is in place for maintenance, protection, and future plantings. OSU has been certified as a Tree Campus USA for 6 going on 10 years and an Urban Forester manages this priority. Landscapes are designed with low maintenance in mind using the appropriate plant to the site conditions. Native and drought tolerant plants are emphasized in all designs but OSU does also use appropriate zone adapted, low water use, non-invasive, non-natives.
Salt/sand mixes are used for ice events only, and only on streets. Sidewalks and parking lots are cleared with mechanical means first. Environmentally friendly ice melt products, with colorant to reduce over-application, have been specifically chosen to use on sidewalks to minimize re-icing. Furthermore, we use recycled paper tree wraps for sunscald protection on new trees, recyclable greenhouse growing pots, cornstarch compostable bags for collecting leaves, and biodegradable wood root ball tree stakes. 4) University Arborist (title change), Organic IPM practices include least invasive methods e.g pressurized water and mild detergent used to wash off pests from trunks & foliage of infected plant specimen.
