"---" indicates that no data was submitted for this field

Total campus area (i.e. the total amount of land within the institutional boundary):
1,026 Acres

Figures required to calculate the total area of managed grounds:
Area (double-counting is not allowed)
Area managed in accordance with an Integrated Pest Management (IPM) program that uses a four-tiered approach 35 Acres
Area managed in accordance with an organic land care standard or sustainable landscape management program that has eliminated the use of inorganic fertilizers and chemical pesticides, fungicides and herbicides in favor of ecologically preferable materials 732 Acres
Area managed using conventional landscape management practices (which may include some IPM principles or techniques) 35 Acres
Total area of managed grounds 802 Acres

A brief description of any land excluded from the area of managed grounds (e.g. the footprint of buildings and impervious surfaces, experimental agricultural land, areas that are not regularly managed or maintained):

The foot print of buildings were excluded from the managed grounds figure provided.

Percentage of grounds managed in accordance with an IPM program:

A copy of the IPM plan or program:
A brief description of the IPM program:

The University IPM Plan includes the following components:

1) Prevention for animal and plant pests: limiting food, shelter and water sources, implementing proper plants, cultural practices.

2) Monitor: maintain a log which contains data of pest populations observed at specific campus locations. Pest identification - properly identify the target pest in order to provide best control methods.

3) Action Thresholds: set action thresholds to determine tolerable damage and best control methods.

4) Control/Management methods: utilize control methods which include; cultural, mechanical, physical, biological and chemical means. When chemical control methods are used, the least toxic material shall be chosen.

Percentage of grounds managed in accordance with an organic program:

A brief description of the organic land standard or landscape management program that has eliminated the use of inorganic fertilizers and chemical pesticides, fungicides and herbicides in favor of ecologically preferable materials:

Currently, campus development is limited to about 274 acres within the 1,026 acre campus site. The land that is currently not part of campus development is managed without the use of any chemicals, including pesticides, herbicides, or rodenticides. Six-hundred thirty three (633) acres of the undeveloped campus is actually grazed by organic dairy farmers who follow the National Organic Program.

A brief description of the institution's approach to plant stewardship:

The University utilizes both formal and naturalistic landscape designs on campus. Priority is given to the use of indigenous plant species and regional native plant species appropriate to the site, climatic and design conditions.

A brief description of the institution's approach to hydrology and water use:

The campus is committed to collecting 100% of its storm water on campus with two retention ponds eliminating storm water and irrigation run off from campus development and keeping the original water that would have absorbed into the pervious ares where buildings are now standing into retention ponds on the campus site that recharges local ground water to help retain the original hydrology.

A brief description of the institution's approach to materials management and waste minimization (e.g. composting and/or mulching on-site waste):

All waste from grounds keeping, including grass trimmings is collected by a third party and composted.

A brief description of the institution's approach to energy-efficient landscape design:

The campus uses an Evapo-transpiration (ET)-based controller from Tucor on our irrigation system. ET is a combination of water lost from plant material through evaporation (from the ground) and transpiration (from the leaves, etc.). The system is programmed with a base ET rate that dictates how long to run and how much water is put down. The ET rate is a function of local climate zone and the type of plant material being irrigated (e.g. turf grass will have a different ET rate than shrubs). Our controller is linked to a weather service that looks at the previous day's ET rate for our area and automatically makes adjustments to the sprinkler run times as required.

A brief description of other sustainable landscape management practices employed by the institution (e.g. use of environmentally preferable landscaping materials, initiatives to reduce the impacts of ice and snow removal, wildfire prevention):

The campus does not have snow and ice.
