ABSTRACT

Presents, analyzes, and discusses information about the ecological
condition of the Upper Mississippi River System. Includes the data and
results from the initial years of the Long Term Resource Monitoring
Program. Science-based ecological status and trends information is
important on this river system with its conflicting interests and values of its
users. Accurate, objective status and trends information supports river
management in three specific areas: (1) ensuring that scientific information
is available so society can understand the basis of resource management
decisions; (2) forecasting the direction of ecological change; and (3)
providing guidelines and evidence to establish ecological objectives.
