Benefit Definitions • Active Benefits: Based on direct use of a resource (i.e., fishing) or services provided by an ecosystem (i.e., water for recreational opportunities, such as boating or swimming) • Passive Benefits: Derived from ecological functions that support active uses (i.e., habitat functions that support fishing) • Intrinsic Values: Knowledge that the resource or ecosystem exists in the world whether we use it or not Colorado Nutrient Cost/Benefit Study 35
