Riparian zones are one of the key drivers of salmon habitat quantity and quality, especially where riparian buffers protect the stream from adjacent land uses. For nearly two decades we have been investigating the ecological connections between riparian zones and streams. A particular focus of these efforts has been quantifying the effectiveness of riparian buffers and riparian restoration in supporting stream ecological function.
