Total campus area:
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 | 31.80 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 | 74.20 Acres |
| Total area of managed grounds | 106 Acres |
If the total area of managed grounds is less than the total campus area, provide:
Building footprints and impervious surfaces, these include Allen Place properties, fraternity houses, and the boat house.
There are two “Low Mow Zones” One on the North side of LSC and the other on the East side of the library.
Organic program
If reporting an organic program, provide:
Soil tests are done 2/3 times per year. Types of organic fertilizer are used based of the soil tests.
14 acres are not sprayed with pesticides for weed control or crabgrass
1. Backyards on Vernon St
2. All along Broad St around athletics fields
3. LSC Quad
4. Hillside between Elton & Jackson
Integrated Pest Management (IPM) program
If reporting an IPM program, provide:
A brief description of the IPM program:
Trinity treats for pests on an as-needed basis only - there is no pre-grub treatment. In the past 2 years, have treated about 1 acre for grub
Optional Fields
New plant beds are planted with native species where applicable. Annuals are mostly used in pots around campus to add color. We avoid planting invasive tree and other plant species.
In Spring of 2023, Trinity's campus was accredited as a Level I arboretum, and we established two low-mow zones.
A brief description of the institution's approach to hydrology and water use:
The athletic field irrigation system has rain sensors. The softball field, prior to Summer 2023, and the game soccer field are controlled by hydrolyzed irrigation clock with rain sensors that are controlled remotely.
Only approximately 25 acres of campus are irrigated - the athletic fields, Gates Quad, and about one quarter of the Main Quad. We water early enough in the day that the grass is not damp when night falls. Moisture encourages disease so minimizing leaf wetness discourages disease and reduces the need for preventative and curative pesticides.
There is a rain garden located behind Summit South.
A brief description of the institution's approach to landscape materials management and waste minimization:
Leaf and stick debris are taken off campus and turned into compost and mulch. When trees are removed, wood chips are repurposed by Connecticut Mulch. Sometimes use woodchips in community garden at Trinfo Café.
A brief description of the institution's approach to energy-efficient landscape design:
A brief description of other sustainable landscape management practices employed by the institution:
We use sand only for ice storms. For regular snow, use only salt. We are experimenting with liquid de-icers (pre- and post-storm).
When we mulch in the spring, we use organic compost around the trees. Not all trees get mulched.
