1. Water Resources Research: River Restoration Katie Halvorson

2.  “Many river restoration projects are conducted with minimal scientific context.” Main point:

3.  “assisting the establishment of improved hydrologic, geomorphic, and ecological processes in a degraded watershed system and replacing lost, damaged, or compromised elements of the natural system” Their definition of river restoration:

4.  Restoration of PROCESS is more likely to succeed instead of a fixed end point.  Only addresses symptoms  Needs to be looked at in the context of an entire watershed. The two ideas:

5.  Lack of scientific knowledge of watershed-scale projects  Dynamics of watershed  Structures that are poorly suited to large-scale management  Lack of political support Limitations:

6. 1.Transferring knowledge from one study to another 2.Restoration actions are applied to too small of scales 3.Integrating disciplinary knowledge into interdisciplinary understanding. Three common factors limiting river function:

7.  Bank stabilization  Fencing  Engineering fish habitat  Commercial uses  Esthetic interests  Recreational uses Quick fixes = not good

8.  >38,000 restoration projects in US  Most commonly stated goals:  Enhance water quality  Manage riparian zones  Improve in-stream habitat  Fish passage  Bank stabilization No complete watershed idea Study

9. “many restoration activities have failed”

10.  Continually develop theoretical framework that allows achieving restoration objectives.  Develop studies examining relative contributions of processes operating at different time and space scales.  Enhance the science and use of restoration monitoring.  Link science, practitioners, and stakeholders. Strategy for achieving vision
