Wetlands, areas of soggy ground with standing water, were seen as undesirable by Pākehā settlers and cleared for farming or urban development. Unsurprisingly, only ten percent of our wetlands remain. They are now seen as precious, important for removing sediment and toxins from water, for protecting land from flooding and for absorbing carbon (eg, peat bogs).
