Managing Cattail (Typha latifolia) Growth in Wetland Systems
… competition, and soil management effects on cattail (Typha latifolia) growth in wetland systems were examined. Soluble reactive phosphorous (SRP), nitrate-nitrogen (NO3-N), and ammonia-nitrogen (NH3-N) removals were tested at a constructed wetland receiving municipal wastewater effluent. Over …

Chemical Treatment of Monodominant Cattail Stands In Semipermanent Wetlands: Duck, Invertebrate, and Vegetation Response
… create openings in dense monodominant stands of cattail in semi-permanent wetlands and the response of breeding and overwater nesting ducks and aquatic invertebrates to the chemical treatments were studied in northeastern South Dakota. Four wetlands were treated with glyphosate in 1985 by …

Wetland and terrestrial phytoremediation of an end-of-life municipal lagoon using cattail (Typha spp.)
… Studies were conducted to quantify cattail (Typha spp.) biomass and nitrogen (N) and phosphorus (P) phytoextraction from biosolids in (i) a wetland constructed in the former primary cell and (ii) a dewatered secondary cell of an end-of-life municipal lagoon. Overall, the …

Shade, Moisture, and Woody Vegetation in Stormwater Management Basins: Influence on Cattail (Typha spp.) Growth
… these basins often retain water; resulting in cattail (Typha spp.) and tree colonization. Managing agencies request cattail eradication and trees are also removed. However, if trees were allowed to remain they could alter basin dynamics, making conditions unsuitable for cattails. In a …

The effects of dormant season burning and flooding on invasive cattail, Typha x glauca, on Rainy Lake and Lake Kabetogama in Northern Minnesota
<p><em>Typha x glauca</em> is one of the most invasive plants in North America. The plant exhibits hybrid vigor and displaces native flora by rapidly forming dense monotypic stands that can break free from the substrate and form floating mat types when established. I tested the effects of …

Evaluation of the subsurface vegetated bed form of constructed wetlands for domestic wastewater treatment
… [woolgrass (<i>Scirpus cyperinus</i>) and cattail (<i>Typha latifolia</i>)]. Twelve larger scale SVBs were constructed at the Powell River Project (PRP) site, Wise County, VA. Treatment consisted of three detention times (4, 8, 12 days) with the same plant species (cattail and woolgrass). …

Dynamics of cicrobial communities associated with <i>Typha angustifolia</i> (cattail) litter in a wetland ecosystem: Effects of litter manipulations on microbial decay processes
<p>Quantification of microbial processes involved in plant decomposition is important in understanding energy flow and nutrient recycling in wetlands. Prior studies examining emergent plant decomposition have often used litter that had been prematurely harvested (senescent) and/or manipulated …

An Evaluation of Three Techniques for the Quantitative Sampling of Marsh Invertebrates
… standing crop on the water surface of dense cattail (Typha latifolia) marshes at 19 sites around the periphery of Caliche Lake in Grant County, Washington.

Transformation and fate of nitrate in northern prairie wetlands
… removed was immobilized within the live cattail fractions and their associated microbes or in the sediment and submersed litter;Plant litter plays an important role in the transformation and fate of nitrate. Measurements of dissolved oxygen profiles using microelectrodes demonstrate that …

Wildlife Habitat Evaluation of the Unchannelized Missouri River in South Dakota
… (9 percent), elm-oak (7 percent), cattail marsh (3 percent), sand dune (3 percent), and sand bar (1 percent). All non-developed habitats except sand bar were sampled to obtain vegetative composition and to determine their value to wildlife. The value of each habitat to nine faunal …

Pheasant Use of Wetlands During The Winter and Application of Landsat Imagery For Assessing Winter Habitat
… Trees, phragmites (Phragmites communis), and cattails (Typha latifolia) were also used regularly. Smartweeds (Polygonum coccineum), roundstem bulrushes (Scirpus acutus and Scirpus validus), and grasses were seldom used. Density was the most important vegetative factor influencing selection of …

Biotic Responses on Typha-monodominant Semipermanent Wetlands To Cattle Grazing
… conditions. Numerous techniques to control cattails such as burning and herbicide application have been suggested. The objective of this study was to test the use of cattle grazing as a method of controlling dense cattail stands in semi-permanent wetlands to improve breeding duck habitat. …

Bat activity over wetlands: temporal and spatial variation
… There was spatial variation in water depth, cattail abundance, and calls from high-frequency bats. Water depth was deeper at one permanent wetland than at one permanent and one non-permanent wetland. Cattail abundance varied across sites. Calls from high-frequency bats were higher at one …

The Breeding Ecology of Least Bitterns (Ixobrychus exilis) at Agassiz and Mingo National Wildlife Refuges
… substrate used for nest building at Mingo while Cattail (Typha spp.), sedge (Carex spp.), bulrush (Scirpus spp.) and common reed (Phragmites spp.) were all used as components for nest building at Agassiz. Birds utilized denser habitat at Agassiz. Nests in the smaller habitat patch at Mingo formed …

Aspects of American Bittern Ecology in Northwest Minnesota
… (P > 0.05) from that in low-use areas except for cattail, which was less abundant in core-areas (P < 0.05). Habitat use was disproportional to abundance (P < 0.005). Cattail, deciduous trees, and willow/grassland were avoided while open water was preferred (P < 0.10). Small sample size (n = 5) …

Performance of Floating Biofiltration in Methane Oxidation
… period: compost-only, plant-only (using cattail Typha spp.), and two mixed compost–plant systems. The performance of these setups was assessed by monitoring oxidation efficiency, microbial population dynamics, nutrient availability, moisture content, and the maximum methane oxidation rate …

Habitat Use and Spatial Ecology of Blanding's Turtle, Emydoidea Blandingii, on Squaw Creek National Wildlife Refuge, Mound City, Missouri
… exhibited a preference for wetlands dominated by cattail (Typha spp.), arrowhead (Sagittaria latifolia) and lotus (Nelumbo lutea). Turtles became dormant in October and hibernated within their summer activity areas.
