Woody stems (trees and shrubs) that were rooted within plots were mapped, species determined and diameters at breast height (DBH) measured.

Trees with DBH ≥ 30cm were sampled with 1ha (40m x 250m) of the plot. The DBH of a tree was recorded at 130cm, unless a tree has a disfigurement on the trunk which would cause an irregular DBH measurement. When this occurs the DBH was recorded at 10cm below DBH. When another disfigurement occurs at this height the DBH was recorded 10cm above the DBH. When another disfigurement occurs at this height the DBH is recorded greater then 10cm below or above the DBH. DBH was measured using veinier callipers or a DBH measuring tape. The DBH measurement on any slope or incline was taken from the lowest side of the tree. If a tree has more than one trunk or branch at DBH height and meets the DBH requirements of it's zone, all trunks and branches were measured and recorded. Any tree, branch or trunk that is dead will only be measured if it has a DBH of 100mm or greater. A dead tree constitutes a tree without living leaves. The position of the tag resides of the largest living trunk or branch. Distance from the transect involved a measuring tape being held horizontally from the plot midline to the centre of the base of the tree from the point closest to the midline and the point furthest from the midline. When on a slope or incline the measuring tape was kept horizontal from the plot midline to the tree by using poles that were used to lift the tape up from the plot midline or up from the centre of the tree.

Brief description

The diameter and breast height and mortality status of woody vegetation was surveyed within 33 one-hectare plots in Karawatha Peri-Urban site between 2009 and 2010.

Lineage

All woody stemmed trees and shrubs were individually tagged (using aluminium tags) and identified within each 1 hectare plot. Woody stems (trees and shrubs) that were rooted within plots were mapped, species determined and diameters at breast height (DBH) measured. A hierarchical design was used to sample trees of different size classes in order to estimate tree density. Trees with DBH 1cm-10cm and height greater than 1.3m were sampled within 0.1ha (4m x 250m) of the plot. Trees with DBH 10cm-30cm were sampled within 0.5ha (20m x 250m) of the plot. Trees with DBH ≥ 30cm were sampled with 1ha (40m x 250m) of the plot. The DBH of a tree was recorded at 130cm, unless a tree has a disfigurement on the trunk which would cause an irregular DBH measurement. When this occurs the DBH was recorded at 10cm below DBH. When another disfigurement occurs at this height the DBH was recorded 10cm above the DBH. When another disfigurement occurs at this height the DBH is recorded greater then 10cm below or above the DBH. DBH was measured using veinier callipers or a DBH measuring tape. The DBH measurement on any slope or incline was taken from the lowest side of the tree. If a tree has more than one trunk or branch at DBH height and meets the DBH requirements of it's zone, all trunks and branches were measured and recorded. Any tree, branch or trunk that is dead will only be measured if it has a DBH of 100mm or greater. A dead tree constitutes a tree without living leaves. The position of the tag resides of the largest living trunk or branch. Distance from the transect involved a measuring tape being held horizontally from the plot midline to the centre of the base of the tree from the point closest to the midline and the point furthest from the midline. When on a slope or incline the measuring tape was kept horizontal from the plot midline to the tree by using poles that were used to lift the tape up from the plot midline or up from the centre of the tree. The distance along the transect was measured by holding a measuring tape at a 90 degree angle to the plot line and recording the distance along the midline tape.
