Culturing Vallisneria americana for Restoration Efforts
Robust Vallisneria americana was cultured for restoration purposes. Preliminary studies, with various iron treatments, were conducted to ascertain the amount of phosphorous release into the water column from sediments. There was a significant difference in the amount of phosphorous released if …

Enhancing Vallisneria americana restoration using knowledge of genotypic and phenotypic diversity
Vallisneria americana Michx. (Hydrocharitaceae) is an ecologically important submersed aquatic plant that once dominated freshwater to oligohaline environments in eastern North America. After dramatic declines it is the target of many restoration initiatives. To increase knowledge of the capacity …

Propagation of Vallisneria Americana (MICHX): Vegetation Management In South Carolina Piedmont Reservoirs
… case. I introduced the submersed aquatic plant Vallisneria americana Michaux to four reservoirs with varied physical settings and management strategies and found that although several obstacles to successful introductions were common to all reservoirs in the study, in each reservoir a particular …

The aquatic macrophyte Vallisneria americana as a biomonitor of site quality in Great Lakes areas of concern.
Leaf-to-root surface area ratios in Vallisneria americana provide a simple and inexpensive, relative measure of sub-lethal effects of organochlorine contamination. The present study was conducted to determine whether this index of surface area could be used as an effective biomonitor of overall …

Ecological aspects of the macroinvertebrates associated with two submersed macrophytes in Lake Kariba
Lagarosiphon ilicifolius Obermeyer and Vallisneria aethiopica Fenzl are the most common and abundant submerged macrophytes in shallow inshore waters of Sanyati Basin, Lake Kariba. Lagarosiphon is structurally more complex than Vallisneria. This study considered the macroinvertebrate assemblages …

Comparison of Bare Root vs. Potted Plants, Species Selection, and Caging Types for Restoration of a Prairie Wetland, and Quantitative Analysis and Descriptive Survey of Plant Communities and Associations at Lewisville Lake Environmental Learning Area (LLELA), Lewisville, TX
… quadrangulata, Heteranthera dubia, and Vallisneria americana. There was no survival recorded in the coarse mesh cages, likely due to the presence of crayfish that are able to get through the coarser mesh and feed on the transplants.
