[email protected] Website www.cec.org.au Edited by John Edwards What is Swamp Sclerophyll Forest? One very recognisable floodplain forest community, commonly referred to as Paperbark Swamp, is more scientifically known as Swamp Sclerophyll Forest. Since European settlement, this community has been decimated, much of it was drained for agriculture, particularly sugar cane in this region, and for urban expansion. As a result it has been listed as endangered, and given the complicated title of “Swamp Sclerophyll Forest on Coastal Floodplains of the NSW North Coast, Sydney Basin and South East Corner bioregions”. That complication does not stop with the name. The term “floodplain” adds another layer of confusion by bringing in the question of what constitutes a floodplain. For example, in making its determination of the endangered status, the NSW Scientific Committee describes the endangered community as occurring on “peripheral parts of floodplains on soils that are usually waterlogged, stained black or dark grey with humus, and show little influence of saline ground water”, specifically, “where they adjoin lithic substrates or coastal sandplains”. This specific wording means that significant areas of Swamp Sclerophyll forest that occur on ‘coastal sandplains’, such as West Yamba, are not considered to be that endangered community. Floristically identical paperbark forests also occur in swamps that are fed from seepage areas, or soaks, which are associated with Kangaroo Creek Sandstone outcrops in the valley. These are similarly excluded from the protection provided to true floodplain communities, even though they are often permanently wet, or regularly subjected to flooding.
