Associated with each treatment site is at least one reference site and at least one degraded site. In two cases, two sites within the same ecoregion share a reference site. This occurs in Deep Creek and Lost Creek in Oregon and Kimball Creek and East Canyon Creek in Utah. These two sets of sites are within reasonable proximity to share the same reference site of Gray’s Creek (Oregon) and McLeod Creek (Utah), respectively. Some but not all degraded sites in our dataset are candidate sites for future restoration projects and can thus benefit from baseline data before restoration takes place. We chose each floodplain and assigned it to a category based on personal communications with local stakeholders and project designers, particularly scientists at the USDA Forest Service, Utah State University Swaner Preserve and EcoCenter, and the stream restoration company EcoMetrics in Colorado. Individual site characteristics are listed in Table 1.
