In order to prioritize restoration needs of a river a survey of the entire river (or preferably the watershed) is needed.  This provides a measure of what the river currently is, and provides a basis for determining restoration needs.  Habitat mapping is designed to assess in stream habitat, with a focus on fish habitat.  Woody debris, substrate, aquatic vegetation, and bedform delineation (run, riffle, pool) are quantified continuously throughout a watershed.  From this information we are able to identify conservation and restoration needs, the idea being to identify the most important problems, not just the most obvious problems.  For example, river habitat mapping can identify if a river needs additional woody debris or has sufficient spawning gravel available.
