Cool Temperate Rainforest in the Pilot Wilderness Area, Kosciuszko National Park, New South Wales: Distribution, composition and impact of the 2003 fires

摘要

Although the distribution and composition of cool temperate rainforest in eastern Australia may be regarded as well documented, the recent discovery of cool temperate rainforest stands dominated by Atherosperma moschatum in the Pilot Wilderness area of Kosciuszko National Park shows that our knowledge is still incomplete. The additional discovery of 10 plant species previously unrecorded for the park including large specimens of Elaeocarpus holopetalus highlights the fact that although the flora andvegetation of the alpine and subalpine tracts of Kosciuszko National Park are relatively well studied, the remainder of the park is by comparison understudied and under sampled. Although not actively protected or managed, these cool temperate rainforeststands appear to have been little affected by the 2003 fires in the Australian Alps, with only 2 stands out of 25 showing any fire incursion. However, whether the direct effects of climate change or the indirect effects of human reaction to climate change poses the greatest threat to the continued existence of these stands is an open question. The aim of this short communication is to: a) examine the distribution and composition of these newly discovered stands of cool temperate rainforest and b) to briefly describe the impact of the 2003 fires on this restricted vegetation type.
