TextPublication details: Winnipeg, MB : 1981. Ducks Unlimited Canada,Description: iii, 23 p. : ill. ; 28 cmOnline resources: Abstract: An evaluation of machinery used to cut common cattail (Typha latifolia)and hardstem bulrush (Scirpus acutus) over frozen substrates, and an assessment of the technique to retard cattail regrowth were conducted in several northern marshes of Saskatchewan and Manitoba. A tractor with rotary mower functioned most efficiently and cost effectively in comparison to a modified swather and tractor-drawn disc. New shoot density, density of flowering plants, and maximum leaf height of cattail were significantly less on cut than on uncut areas after 1 growing season. Water depth in mid-May was negatively correlated with new shoot density, whereas water depth reduction between May and August and maximum stubble length were positively correlated with stem density.Continued decreased cattail regeneration on cut areas after 2 growing seasons seemed linked to both the impacts of cutting and flooding during the 1st growing season and to the persistence of drought during the 2nd season.
