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 | 1 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 | 1,040 Acres |
| Total area of managed grounds | 1,041 Acres |
If the total area of managed grounds is less than the total campus area, provide:
800 acres Cowling Arboretum
Leased Farm Land (Mike Peterson Farm)
Buffer Zones, which are woodlands and prairie
Student Organic Farm (1 acre)

If reporting an organic program, provide:
The Carleton Arboretum practices sustainable land management with things like prescribed burns to help maintain the local species and promote sustainable growth. We also use goats to eat invasive species in specific areas of the arb. We do not have a certified organic program for managing the Arb at this time. More information about the Arb can be found here: https://apps.carleton.edu/campus/arb/management/

A brief description of the IPM program:
Although there is no written IPM plan, Carleton grounds does follow certain protocol to ensure that as few synthetic chemicals are needed as possible. This includes keeping herbicides off of Carleton's main campus, and converting grounds so that they have lower intensity management.
The Arb does not use organic herbicides and fertilizers. When first planting trees we add a commercial fertilizer tablet to each tree planted. The number of trees the fertilizer is used on is fairly small - the 250 that we plant with the freshman in the fall and the 50 we do at Earth Day each spring. That is the only fertilizing we do for trees.
For herbicides - we do use them and none of them are organic. We are very limited and careful in our use but have to use conventional herbicides to get the work done.
We do not have a website that specifically details our herbicide or fertilizer practices:https://apps.carleton.edu/campus/arb/species/invasives/

Optional Fields
Carleton College has four landscape zones with a design strategy for each zone. The design strategy in each zone includes a focus to feature and consist primarily of plant species native to Rice County and southeastern Minnesota with the understanding that responsible and sustainable land practices favor the selection and predominant use of fully hardy species that are native and/or adapted to the region.
A brief description of the institution's approach to hydrology and water use:
During restoration of green space and landscape zones we have been conscious of how water moves and where it is going. Our goals in may instances are to capture the water for infiltration purposes. Not all areas is this practice possible but we are trying to integrate infiltration and reuse into our restoration projects.
A brief description of the institution's approach to landscape materials management and waste minimization:
In general, the mower decks mulch the grass clippings well and the organic matter and nutrients are returned to the turf unless an area gets away from the Grounds department. Then, the grass clippings are collected and placed in a campus compost pile. All other organic yard waste goes into this pile as well, excluding woody materials.
A brief description of the institution's approach to energy-efficient landscape design:
The Grounds Department is gradually decreasing the total area of non-recreational mowed turf landscape, replacing this area with natural landscapes.
A brief description of other sustainable landscape management practices employed by the institution:
The Grounds department attempts to remove snow as it falls to reduce the need for using deicing chemicals and sand. Carleton also pre-treats high traffic areas with a moderate amount of deicer to avoid snowpack and the need for larger amounts of deicer. Carleton College also uses only about a 20% salt content sand/salt mixture to treat most of the road/walkways.
