Queensland mangroves have always been affected by adverse natural climatic conditions that are manifest seasonally and annually in the first instance, and episodically with severe events. Various natural factors pose significant threats. Changing rainfall conditions result in expansion or contraction of mangrove areas depending on fluctuations in rainfall. Physical damage to foliage and stems is caused by severe wind and hail storms. Sea level rise results in zonal shift that replaces upland vegetation. Other influencing factors include: increased sea surface temperatures and decreased coastal frosts; insect infestations like caterpillar plagues result in significant defoliation inhibiting mangrove growth and survival; storm-wash wrack smothers breathing roots and trees die; and, erosion destabilizing trees and redeposition of fine sediments buries breathing roots to…
