Total campus area:

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 | 29.40 Acres |
| Area managed in accordance with an Integrated Pest Management (IPM) program that uses selected chemicals only when needed | 1,364.70 Acres |
| Area managed using conventional, chemical-based landscape management practices | 44.42 Acres |
| Total area of managed grounds | 1,438.52 Acres |
If the total area of managed grounds is less than the total campus area, provide:
The total area of managed grounds was calculated based on:
(Total area) - (Building Footprint) = Managed Grounds
Includes:
Tempe, Polytechnic, Lake Havasu City, Phoenix Municipal Stadium, Downtown, and West locations.

Organic program
2.04
If reporting an organic program, provide:
The organic landscaping program applies to a few different areas at ASU:
- The former "driving range" land at the Polytechnic campus is maintained through mowing but no chemical treatments are applied
- The Desert Arboretum on the Tempe campus is maintained without chemicals
- Community garden spaces
In our community garden spaces, the following practices are used:
- No pesticides or herbicides are used, only organic sprays when needed.
- Crop rotation practiced.
- Only organic soil amendments are used in the beds.
- Green waste composted on site and put back into garden beds.
- Cardboard used as a mulch to deter Bermuda grass from growing.
- Lady bugs have been released into the garden as a form of pest control.

Integrated Pest Management (IPM) program

A brief description of the IPM program:
ASU currently looks to the UC Integrated Pest Management (IPM) guidelines from the University of California for best practices in IPM. Weeds are mechanically removed whenever practicable. When necessary, weeds in landscaped areas, ROWs and turf are controlled with herbicides labeled “Caution” only. Insect pests are managed with organic-based products including BT, insecticidal soaps or diatomaceous earth. “Caution” labeled insecticides may only be used in case of extreme infestations that may not otherwise be controllable. Wildlife is present on our campuses and is generally left unmolested except when populations become untenable or when the wildlife presents a health or safety risk. Wildlife observed includes ants, aphids, bees, mosquitoes, roaches, diverse rodents, bats, cats, coyotes, foxes and pigeons. When necessary animals are trapped and released. The population of feral cats is significant and ASU works with local volunteer organizations to execute a continuous trap, neuter and release program.
Optional Fields
The Tempe campus is a registered Arboretum with an extensive collection of plants. It encourages the use of Native Plants where appropriate. Since there is a limited palette of native trees in this area, the Tempe campus Arboretum also uses non-native plants. Only non-native plants and trees that are adapted to the heat of our Sonoran desert climate are selected by the Office of the University Architect's landscape architects. The landscape architects specify the plant material for all of the ASU campuses. The Tempe campus does not have a problem with invasive species.
The West campus has an extensive collection of native trees in their arboretum east of the Faculty Administration Building.
The Polytechnic campus is a registered desert arboretum. It maintains native plant species specific to the Sonoran desert including varieties of cacti, succulents, shrubs, herbaceous wildflowers and deciduous drought-tolerant trees.

A brief description of the institution's approach to hydrology and water use:
ASU is transitioning to smart irrigation controllers to manage water use.
A brief description of the institution's approach to landscape materials management and waste minimization:
Arizona State University is developing a university-wide composting program that includes food waste and green waste. The University purchases the resulting compost for use on campus landscapes to reduce the need for artificial fertilizers. A similar program exists on the Polytechnic campus. The amount of landscaping waste generated on the Downtown Phoenix Campus is negligible.

A brief description of the institution's approach to energy-efficient landscape design:
Arizona State University installed a PowerParasol solar PV array next to the Memorial Union building which provides shade for a series of study tables and a performance stage.
There are several shaded gardens for outdoor lunch areas and social gathering spaces.
ASU has replaced its Palm Walk palm trees with date palms that not only provide more shade but also provide an edible landscape.

A brief description of other sustainable landscape management practices employed by the institution:
Arizona State University’s approach to sustainable landscape management focuses on using desert-adapted plants and working to minimize turf use in community spaces. Centrally controlled irrigation systems are being installed across the university to ensure the optimal amount of water is used. Organic fertilizers (compost, compost tea, hydrolyzed fish solution, and other organic fertilizers) are used in order to minimize conventional fertilizers.
ASU has also integrated edible plants into its landscape as an engagement tool. Examples include dates, citrus, and herbs.
Finally, ASU works to reuse landscape elements and leftovers from construction (boulders, pavers, and misc. items) for use in the landscape.
