Abundance of Hollow Bearing Trees at Karawatha Forest Park, South East Queensland Peri-Urban SuperSite, Karawatha, 2009

The abundance of hollow bearing trees (>30 cm DBH) was measured on 33 one hectare PPBio plots at Karawatha Forest Park. Tree and hollow attributes were measured for each HBT detected during these surveys. Plots were spaced at 500 m intervals, followed the elevation contour and each plot was 250 m long and 40 m wide. Tree and hollow characteristics were also measured.

本研究于卡拉瓦瑟森林公园的33个一公顷PPBio样地中，测定了胸径（Diameter at Breast Height，DBH）大于30厘米的空心树的丰度。针对此次调查中发现的每株空心树（Hollow-bearing Tree，HBT），均记录了其树木与树洞的属性参数。该系列样地沿等高线布设，样地间距为500米，单一样地尺寸为长250米、宽40米。此外，本研究还测定了树木与树洞的各项特征参数。
