520 | 0 |a"Level ditching has been suggested as a method to provide waterfowl brood-rearing habitat along floodplains. Level ditches were excavated in 1988 and 1989 at three sites along the Saint John River near Fredericton, New Brunswick. Level ditches were designed to be sinuous in shape, 6 m wide, with a 2:1 slope on the sides of the ditch, with the centre 2.5 m section being 0.9 min. depth. We quantified the use of level ditches along the Saint John River floodplain by waterfowl broods during 1990-1995. The suitability of the habitat was evaluated in relation to water chemistry, algal biomass, vegetative community and invertebrate abundance"--Abstract, p. i. |
