Key to Methods - Historic Rankings and Decision Rules
Historic Rankings: Indicates whether the watershed had been ranked to be of special quality in previously published reports. The historic rankings include:
• National Park Service (1982) Nationwide Rivers Inventory. Streams considered for potential Wild and Scenic River status,
• The Nature Conservancy (1985) “Priority Aquatic Sites” for biodiversity conservation,
• U.S. Fish and Wildlife Service (1988) list of “High Quality” streams,
• Hawai'i Cooperative Park Service Unit (1990) Hawaiÿi Stream Assessment. Streams rated as Outstanding, and
• M.A.P.S. - Multi-Attribute Prioritization of Streams Project (Uyeno 1998). Streams rated as Potential Heritage Streams.
Current DAR Decision Rule Status: The decision rule status reflects a yes or no assessment of the watershed for certain specific traits. The presence of these traits (a yes answer) is considered a good attribute of the watershed and the stream.
