A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):
OSU landscapers have taken many steps to reduce their operation's impact on the environment:
* Incorporating native and/or drought tolerant plants into landscaped areas
* Leave grass clippings on the lawns to return nutrients
* Obtain annual Oregon Dept. of Agriculture training to maintain pesticide best practices and application licenses
* Maintain the campus to different standards based on need (i.e., MU quad vs. low profile areas)
* Use of Maxi-com computerized irrigation system with weather-based watering to conserve water
* Minimal use of only slow release fertilizers to avoid fertilizer run off
* On-campus handling and chipping of woody debris and compostable material
* Application as groundcover of mulch and wood chips to reduce watering and weeding needs
None
A brief description of any weather-informed irrigation technologies employed by the institution:
Our Rainbird Maxicom computerized system uses local weather data to determine appropriate water levels, based on evapotranspiration (ET) indicators.
OSU Landscape Crew also performs annual irrigation audits to verify automated system performance.
