Abstract:Large river-floodplain ecosystems have been defined as those where the flood is sufficiently predictable and long lasting that organisms have adapted to utilize the flooded land and expanded floodplain pools and lakes for feeding, spawning, and nurseries (Junk et al . 1989). The habitat complexity and dynamic nature of large floodplain rivers boost biological productivity through a variety of biotic and abiotic processes (the "floodpulse advantage" described by Bayley 1991), but also challenge biologists who design sampling programs to detect trends and sort out natural from human-induced changes in fish and wildlife populations. The Illinois River is a good test for survey design and for problem identification and assessment techniques because it is a large, complex floodplain river and has experienced virtually every impact associated with human development of rivers and their basins, with the exception of acid mine drainage and high dams (Sparks 1992). This paper describes a long-term fish population survey on the Illinois River and how the results provided preliminary insights into problems that subsequently were investigated using ancillary sampling and toxicity evaluations.
