It is the policy of Yale University to practice Integrated Pest Management (IPM) as a means to control unwanted pests on all Yale grounds. Yale University avoids routine pesticide applications by utilizing knowledge of pests and the local environment which allows effective monitoring of plants and action thresholds. By practicing IPM, Yale University aims to minimize risks associated with landscape pests and pesticides for the entire campus. In addition, designated areas around campus are mowed two to three times a year to encourage the development of an urban meadow. Urban meadows promote natural regeneration, leading to increased biodiversity, improved water quality, and a reduction in stormwater runoff and soil erosion. In addition, less frequent mowing reduces fuel and equipment usage, saving money and improving air quality.
