OP-10: Landscape Management

The objective of OSU's IPM plan is to maintain pest populations below action threshold levels while ensuring minimal human exposure to health risks, inflicting minimal hazards on the environment, providing effective monitoring through inspections and standardized record keeping, and evaluating the effect of IPM practices. OSU's IPM plan aligns with EPA's plan in relationship to setting action thresholds, monitoring and identifying pests, and in prevention and control strategies. Environmental Health and Safety is responsible for ensuring that landscape services and all departments on campus follow proper IPM guidelines.

While we do not have a formal sustainable landscape plan, the other details on this page specify OSU effort to minimize impacts from landscaping activities.

OSU acknowledges the importance of using native plant species in landscaping practices. According to OSU Facilities Services Manager Joe Majeski, "Native plants are being incorporated into many of the new landscape areas. Also drought tolerant plants are used as well in many areas. We utilize a computerized irrigation system that measures: temperature, wind, humidity and rainfall and then meters just the amount of water required for optimal plant growth." Additionally, People's Park at OSU showcases native and drought tolerant plants to demonstrate more sustainable landscaping practices.

These small lawn areas are particularly resource in intensive and don't provide the same benefits that larger lawn areas do. For invasive species control, volunteer crews are used periodically to remove the two major invasive plants in this area: Himalayan blackberry and English ivy. Many of these volunteer events are student focused and include a service learning component.

The use of compost or mulch waste is a priority set by landscapers at OSU. On-campus handling and chipping of woody debris and compostable material ensures these materials are returned to the soil. Grass clippings are left on the lawns to return nutrients. All leaves are composted on-site, and mulch and wood chips are applied to OSU grounds to reduce watering and weeding needs. All wood waste from landscaping is chipped on site and used on site. Green waste, except that from invasive species, are processed on site. Invasives are composted off site at a commercial facility.

Landscape crew has changed their practice to leave leaves in place. Leaves are moved into landscaped areas rather than being hauled away to compost at another part of campus. In place composting under large plants and trees reduces transportation fuel, labor hours and provides year-round mulch for water and nutrient retention, and soil amendment.

This is not currently included in OSU's efforts, with exception of some small permeable concrete areas for park benches.

Several bioswales are in place on campus, and a major road reconstruction project in FY14 included a very large swale. The Oldfield Animal Teaching Facility includes a vegetated swale with a small bridge over it near the entrance to a building, making these efforts as visible as possible. OSU assembled a water resources brochure to educate the public about the ways in which OSU is reducing its impact on water resources and consolidate information about this work. It can be found at http://fa.oregonstate.edu/sustainability/resources-visitors.

OSU is located in a temperate climate that receives little snow but some ice on roadways. When needed, only products labeled as safe for the environment are used in ice removal. Steam distribution systems under many of the sidewalks on campus further help to melt ice. When needed, a gravel/sand mix, rather than chemical treatments or salt, is used on roadways.

Protected areas at OSU include the following types of areas, counted in the acreage above: -LEED reserve -Riparian protected areas -Highly Protected Significant Vegetation -Conservation Reserve Enhancement OSU's total protected land is 648 acres, of a Corvallis total of 1639 acres, which includes farmlands.

Problems with STARS terminology make this credit challenging, particularly "building footprint" and "undeveloped." The terminology for this credit is unclear and results in a questionable score. There is not guidance on whether or not sidewalks, parking lots and other impervious areas should be counted toward "Footprint of the institution's buildings." OSU has this year reported only the acreage of the buildings themselves. Terminology used should include pervious, impervious and other conventional land use planning terms. "Undeveloped land" also lacks a clear definition. Undeveloped, as OSU has reported below, equals no impervious acres+no protected acres. Where are impervious non building acres to be counted? How are farmlands with minimal management counted? Additional notes on IPM: OSU's Facilities Manager, Joe Majeski, has stated, "IPM practices are used on all the grounds in accordance with state and federal laws." Below is the Oregon Department of Agriculture's IPM plan. Departments at OSU must develop IPM programs that are consistent with state laws. Oregon State's IMP guidelines are offered below to illustrate how the State's plan aligns with the EPA's four-tiered IPM plan. Definitions for ORS 634.650 to 634.665. As used in ORS 634.650 to 634.665: (1) “Integrated pest management” means a coordinated decision-making and action process that uses the most appropriate pest control methods and strategy in an environmentally and economically sound manner to meet agency pest management objectives. The elements of integrated pest management include: (a) Preventing pest problems; (b) Monitoring for the presence of pests and pest damage; (c) Establishing the density of the pest population, which may be set at zero, that can be tolerated or correlated with a damage level sufficient to warrant treatment of the problem based on health, public safety, economic or aesthetic thresholds; (d) Treating pest problems to reduce populations below those levels established by damage thresholds using strategies that may include biological, cultural, mechanical and chemical control methods and that shall consider human health, ecological impact, feasibility and cost effectiveness; and (e) Evaluating the effects and efficacy of pest treatments. (2) “Pest” means any vertebrate or invertebrate animal, pathogen, parasitic plant, weed or similar or allied organism which can cause disease or damage to crops, trees, shrubs, grasses or other plants, humans, animals or property.
