... Integrated resource management is the term this committee uses to indicate resource management that seeks to restore the structure and function of whole ecosystems by striving to understand and respond holistically to cumulative ecological impacts. The integrated approach to aquatic restoration tries to consider the major ecological interactions in a watershed and seeks to nurture the watershed's restoration to a functioning system, rather than to manage for a single species or for a resource commodity such as game fish.
From page 342...
... By contrast, the Great Lakes Water Quality Agreement of 1978 requires signatories to consider the cumulative influence of each chemical, a more integrated approach (NRC/RSC, 1985~. However, aquatic ecosystem restoration requires more than water quality management.
From page 343...
... The politics and consensus building required for integrated management of the resource are often as complex as the ecosystem itself. IMPORTANCE OF INTEGRATED AQUATIC ECOSYSTEM RESTORATION TO WILDLIFE The amount and timing of water fluctuations and changes in water quality constitute the most important variables limiting the viability of many species of plants and animal populations.
From page 344...
... For example, wetlands around the Great Salt Lake are widespread during years of heavy rainfall and runoff; marshes along the Colorado River expand after months of river flooding; prairie potholes expand in size and number during wet years; adjacent lakes that are separate in dry years may merge in wet ones; stagnant waters become flowing with increased runoff. A site designed as a marsh might eventually become a pond or a lake, or vice versa.
From page 345...
... Future restoration projects would benefit from a large-scale integrated management approach that seeks to help managers understand what attracts and supports mobile species within a target area. APPROPRIATE SCALE FOR AQUATIC ECOSYSTEM RESTO - TION Gosselink and Lee (1989)
From page 346...
... By examining original land survey data, early U.S. Geological Survey maps, and early soil maps, experts can develop maps of a watershed's stream flow and land use patterns at various times.

... data base so that a wide variety of parameters can be examined simultaneously. Sets of related data when superimposed on a GIS map often reveal opportunities for restoring aquatic ecosystems so as to maximize a number of functions, such as reduction of flood damage, erosion control, habitat for species of concern, and water quality improvement.
