Re: Sulphur Affecting MangrovesPosted by Andrew Thor on September 30, 1999 at 16:28:23: Piwatter Council recently improved an area of Pittwater estuary by transporting sand & mud from an area in close proximity to batter a bank of a reserve on the edge of the bay. Transplanting of mangrove seedlings from the same site occured shortly after the sand and mud was rellocated. The sand and mud was possibly contaminated with pollutants from marine craft. All the seedlings have died. It has been suggested that an excess of sulphur was released when the sand & mud horizons were disturbed thus killing the seedlings and micro organisims. Does this sound like a feasable explanation and is it possible there is a solution to this problem. Please enlighten me with any suggestions you may have that may help regenerate the area.
