Mangrove dieback in Mackay Region Investigations in 2002 with Recommendation for further research, monitoring and management - Report September 2003 Dieback of mangroves in the Mackay region continues to be serious and progressive. After 2 years, mangrove plants, particularly Avicennia marina, the common mangrove, continue to show signs of deteriorating health and stress. Furthermore, there are serious implications from the dieback where sediment erosion appears to have increased from estuarine mudflats previously forested with thick stands of mangrove trees. Further field studies by UQ Centre for Marine Studies Marine Botany group were conducted in 2002. The results of these studies revealed that mangrove dieback was still advancing, especially in Basset Basin of Pioneer River estuary.
