Our program has been evaluated by Salmon-Safe, an independent certification organization that assesses land management practices and their possible effects on aquatic ecosystems. A park system is considered salmon-safe when both its impact upon the aquatic ecosystem is assessed and any harmful impacts on water quality and fish habitat are minimized. As part of the process, Salmon-Safe certification includes extensive on-site visits by qualified inspectors to ensure that standards are being met. As Salmon-Safe puts it: "Park and Natural Area Certification Standards constitute a set of best management practices that can be applied across a variety of landscapes from natural areas to golf courses to sport fields."
Their final report stated: "PP&R's management of the Portland park system serves as an outstanding example of exemplary management of an urban public recreation and natural area resource. The organization's management and park maintenance staff understand, support, and implement a stewardship vision for the lands under their care." And: "Pesticide use within Portland's well-established IPM program is minimal and well justified. Pest management decisions and methodology are based on sound scientific information. The Portland program has served as a model for others that IPM is practical and effective as well as ecologically responsible."
