The tractor-rotary mower functioned most efficiently and cost effectively. Cattail stem density, maximum leaf height, and density of plants with fruiting bodies were significantly less on mowed than on unmowed areas. Water depth in mid-May was strongly negatively correlated with cattail stem density on mowed areas. Water depth reduction between May and August and maximum stubble length were significant positive correlates of cattail stem density. Spring inundation of cattail stubble impedes oxygen transfer to the rhizome system, which eventually results in death of the plants. Cutting cattail in manged waterfowl habitats appears to be an expedient and economical means of increasing cover-water interspersion, and potentially provides invertebrate-rich fora
