Monitoring and research strategies of the Long Term Resource Monitoring Program require a current, objective understanding of the factors that control ecological structure and function of floodplain reaches within the Upper Mississippi River System. The conceptual model presented here is designed to fill part of this need by listing major factors (abiotic and biotic) and disturbances (natural and human-induced) that operate at each of five spatial scales. In decreasing order of size, the spatial scales include: basin, stream network, floodplain reach, navigation pool, and habitat. Major factors are defined as those which act to keep ecosystem variables within predictable limits over a reference time period. A disturbance...

Evaluations of Long Term Resource Monitoring Program sampling designs for water quality, fish, aquatic vegetation, and macroinvertebrates were initiated in 1999 by analyzing data collected since 1992 in six trend analysis areas. Initial emphasis was placed on evaluating statistical power to detect change from one year or sampling interval to the next, and on determining what spatial, methodological, or target variable redundancies existed in the data sets. Power to detect change was evaluated at halved, present, and doubled levels of effort. Power to detect change for different variables varied widely and was greatly influenced by sample size and for species by their frequency of occurrence. Power for detecting...

Fishes are one of the most diverse and abundant natural resources of the Upper Mississippi River System (UMRS) (Carlander 1954; Rasmussen 1979; Van Vooren 1983; Fremling et al. 1989). Several features contribute to the great amount of interest fishes receive from the general public, fishery managers, and aquatic ecologists: a. UMRS fishes support multimillion-dollar commercial and sport fisheries. b. Fishes respond to a variety of hydrologic, water quality, and habitat variables. c. Scientists and fishery managers recognize fish communities as an integrative index to a complex set of physical and biological conditions on the UMRS; that is, fish are indicators of the biotic integrity of the UMRS. In addition, impacts...

The purpose of this workshop is to identify important hydro- and ecological relationships that will affect the ability of floodplain managers to optimize their approaches to providing: 1) fish habitat; 2) wildlife habitat; 3) nutrient and sediment processing; and 4) flood regulation. The resulting conceptual model will guide future floodplain science, including the development of numerical simulation models of high interest relationships. Twenty participants at the workshop included science experts on each of the four floodplain functions, policy analysts, and floodplain managers faced with making optimization decisions. The workshop report will focus on relationships of greatest need of quantification and how they...
