Economic Value of Aquatic Vegetation to

by James P. Kirk, Jim E. Henderson
"... Aquatic vegetation is important, both in terms of positive and nega-tive effects, to anglers, boaters, utilities, shorefront property own-ers, and waterfowl interests who utilize reservoirs. Multiple users of lakes and reservoirs complicate aquatic plant management deci-sions. Balancing limited fund ..."

Migratory waterfowl habitat selection in relation to aquatic vegetation

by G. Owen Dick, Joetta K. Smith, R. Michael Smart - ERDC/TN APCRP-EA-09. United States Army Engineer Research and Development , 2004
"... PURPOSE: This technical note describes studies of environmental conditions and habitat quality of replicated pond ecosystems dominated by populations of exotic plants or mixed communities of native aquatic plants. Study ponds were similar in depth, size, and shape, as well as in (initial) water and ..."

Submersed Aquatic Vegetation Modeling Output Online

by Yao Yin, Jim Rogala, John Sullivan, Jason Rohweder , 2005
"... The ability to predict the distribution of submersed aquatic vegetation in the Upper Mississippi River on the basis of physi-cal or chemical variables is useful to resource managers. Wildlife managers have a keen interest in advanced estimates of food quantity such as American wildcelery (Vallisneri ..."

"... ABSTRACT: The overall objective of the project was to begin restoration of spawning and nursery fish-ery habitat for the sunfish family (largemouth bass, crappie, and bluegill) lost from flood control opera-tions (seasonal drawdowns) in El Dorado Lake, Kansas. When initially impounded, flooded terre ..."

Specific objectives of the project were to: (a) evaluate the suitability of several emergent, floating-leaved, and submersed aquatic plant species for establishment in the lake; (b) develop and test effective methods for establishing desirable aquatic plant species; and (c

CHAPTER 8 Submersed Aquatic Vegetation

by Sara Rogers, Charles Theiling, Submersed Aquatic Vegetation
"... (SAV) includes plants with leaves and stems that grow on or under the surface of the water (Figure 8-1), usually found anchored to the sediment by their roots. This chapter covers what is known about the dynamics of these submersed vascular plants in the Upper Mississippi River System (UMRS). The di ..."

). The discussion does not emphasize floating-leaved species and macroalgae. Historically, submersed aquatic macrophytes have played several important roles in the Upper Impounded Reach of the UMRS (Green 1960). Plant communities generate dissolved oxygen, stabilize mucky sediments, filter suspended particulates
