Total campus area:
1,791.22 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 844.72 Acres
Area managed in accordance with an Integrated Pest Management (IPM) program that uses selected chemicals only when needed 0 Acres
Area managed using conventional, chemical-based landscape management practices 946.49 Acres
Total area of managed grounds 1,791.21 Acres

A brief description of any land excluded from the area of managed grounds:
In Campus Area, we are using only Vegetated Grounds of 1,791 acres. This figure excludes 578 acres of impervious surface from the total area of managed grounds. This includes: building footprints, curbs, sidewalks, parking lots, and roads.

We include in this figure the total between crew zones, Griffy Reserve, and Golf Course.

Percentage of grounds managed organically:

A brief description of the organic landscape management program:
Athletic fields and the Golf Course are largely contracted spaces; thus, we consider these grounds as “conventionally managed.”

Of the vegetated grounds, 844.72 acres are managed organically, meaning the use of fertilizer and chemical pesticides, fungicides, and herbicides are not used.
Also included in the acres that make up the core campus footprint is “Griffy Woods,” a 185-acre parcel that is managed as part of the IU Research and Teaching Preserve. The mission of the Preserve is to “provide natural field settings for research and teaching that complement existing facilities and infrastructure at Indiana University.” In keeping with the mission, organic management and maintaining ecological health/integrity is paramount to the Preserve’s success.

Additionally, Hilltop Garden and Nature Center is approximately 4 acres and is maintained organically.

Two 10-acre urban woodland sites are maintained by a team of students, faculty, and professionals who work to remove invasive species and reintegrate native species. These sites serve as a model for the importance of urban green space and the services provided by woodland environments.

Percentage of grounds managed in accordance with an IPM program:

A brief description of the institution's approach to plant stewardship:
During the summer of 2019, two undergraduate students completed a tree inventory of all free-standing trees on the “core campus.” Collaborating with the Office of Sustainability and Landscape Services’ team of arborists, the students collected the condition, GPS coordinates, size, species, maintenance needs, and other valuable notes of interest on over 12,000 trees and stumps.

Using this recent inventory and a previously performed tree inventory of 2016, undergraduate and graduate students summarize the current status of the tree community, analyze trends, and develop a strategic tree planting plan for the future. We plan to continue updating and re-inventorying free-standing trees regularly so that Landscape Services can efficiently manage our Woodland Campus.

In addition, Landscape Services staff collaborated with graduate classes in the O’Neill School of Public and Environmental Affairs to survey woodlots on campus and analyze trends within woodlots and free-standing trees. Their analysis has informed how we can reduce and prevent invasive species presence on campus.

Landscape Services is also working to re-design mulched landscape beds to incorporate more native and sediment-stabilizing plants that shade out weeds naturally. This approach will facilitate the reduction of herbicide use on campus.

In addition, Landscape Services is working to reduce the number of mulched landscape beds to reduce the need for upkeep and use of herbicides.

A brief description of the institution's approach to hydrology and water use:
Wetland areas are closely monitored and maintained. Drainage areas are protected from run off during construction projects. Storm drains are protected with sediment bags to prevent sediment loading of waterways.

A brief description of the institution's approach to landscape materials management and waste minimization:
Mowers are equipped with mulching blades. Leaves and organic debris are composted at IU's nursery and then re-utilized on campus. Some tree waste is re-processed and utilized by outside vendors. IU is in the process of upgrading composting facilities to more efficiently produce organic fertilizer and break down organic debris from campus.

A brief description of the institution's approach to energy-efficient landscape design:
Campus Division (steward of the IUB landscape) has reduced irrigation on the campus interior, reduced mowing on the campus perimeter, and implemented stormwater management best practices in all new construction.

A new SMART irrigation system has been installed at the IU Pfau Golf Course, which will decrease the time involved in maintaining an irrigation system as well as reduce water and fertilizer use.

A brief description of other sustainable landscape management practices employed by the institution:
IUB stopped utilizing sand several years ago because of sediment loading in waterways.

We are now utilizing salt brine technology on campus which is reducing our salt use by approximately 25%. IUB has not yet found a cost-efficient replacement for salt, but it is used more carefully than in the past and we continue to explore environmentally friendly ice melters.
