“As long as the wetland looks pretty and also attracts ducks from time to time, it is regarded as a complete success. An attractive appearance is fine and is of considerable concern in urban developments. It is the pretense that such wetlands also create rich habitats which is objectionable, when urban development is the primary cause of loss of diversity in a wide range of ecosystems around cities including wetlands. The one ecologically positive thing that most created wetlands do a reasonable job of is water treatment, because the limited range of plants likely to survive the semi-toxic soils and waters of newly created wetlands are invariably colonisers that will also use up a wide range of nutrients.” HabitatEcosystemWetlandsUrban Encroachment Book:Wetland Habitats [OP]: A Practical Guide to Restoration and Management Source: Wetland Habitats [OP]: A Practical Guide to Restoration and Management
