There is a lack of certainty on the future impacts of climate change on our coastal environment. A recent study by Parks and Wildlife reported that since 2000 rainfall is significantly lower and there has been a greater frequency of fires covering the park (Zdunic and Huntley 2015). The report said that rainfall is a key driver for native vegetation cover in the park and a gradual reduction in rainfall may result in tree decline over time. As rainfall declines and vegetation density reduces, the spread of Dieback may also reduce (as water and root to root contact are key factors in the spread of the disease). Climate change may also result in shifts in species dominance as different species may thrive in changing conditions and increased bare earth provides the opportunity for weeds to thrive.

Other impacts of climate change may include storm surge and flooding that may impact the values of the park through erosion, loss of native vegetation and loss of coastal integrity.

Management

Changes in climate and fire regime may have implications for park management, particularly in relation to fire management, dieback and weed control.
