RESTORATION OF LOWLAND STREAMS: THE BUILDING BLOCKMODEL
In many agricultural areas the small streams have been reduced to drainage ditches. This not only has destroyed important natural habitat but has reduced the self cleaning and nutrient reduction ability of agricultural streams. There is now much discussion about how this trend can be reversed in a practical and cost effective way without disrupting the productivity of our farmland. In the present article a series of stream restoration measures, all which can improve the natural habitat and reduce nutrient leakage, are proposed. The restoration measures should be viewed as a series of building blocks which can be combined in various ways depending on individual landowner preference, available financial resources and landscape form.
