Sampling methods and functionally related landscape metrics were developed for characterizing riparian-stream networks using aerial photography and GIS. A sample area was empirically derived from using morphological characteristics of increasing portions of the stream network surrounding points selected on streams. GIS functions were used to band stream networks in 10-m increments to a distance of 300 m, within which land cover was interpreted form areal photographs and digitized. Incremental banding is an effective is an effective approach for characterizing the composition and pattern of land cover as a function of distance from the stream network. Structural attributes that capture the linear nature of riparian-stream networks, such as the composition, width, longitudinal extent, and connectivity of woody vegetation, were characterized. The methods developed provide a flexible framework for deriving landscape metrics of functionally important structural attributes of riparian-stream networks for exploring relationships at varying spatial scales with indicators of stream ecological condition.
