An early black and white photograph of a sample acre of tall trees near Marysville in Victoria.An early black and white photograph of a sample acre of tall trees near Marysville in Victoria. After the devastating 1939 ‘Black Friday’ bushfires, Victoria’s tallest known trees were to be found in the Cumberland scenic reserve, 20 km north-east of Marysville. This stand of trees was set aside in the 1920s to preserve a ‘sample acre’ of tall trees. It originally contained 27 trees, the tallest of which was said to be 92 m, whilst the average height was 81 m. A severe wind storm in 1959 blew down 13 trees and left the ‘tall tree’ at a reduced 84 m (Munro 1992). An examination of the crown of this tree by arborist Tom Greenwood (Tom Greenwood pers. comm. 2001) suggested that it was unlikely that it ever reached the original figure of 92 m; the current height is 81.5 m, a figure used as the starting point for this search for Victoria’s tallest trees.

Foresters usually measure the diameter of trees at Breast Height – traditionally 4 foot, 6 inches – now 1.3 m – which is termed Diameter Breast Height Over Bark (DBHOB). Basal Area is the cross section of the tree trunk at breast height, and the sum for the stand or group of trees is expressed square feet per acre (after 1973 it was expressed in square metres per hectare). Lots of skinny trees, or a few fat ones, can have the same Basal Area, but when combined with the number of stems, Basal Area is a good indicator of stand density. Two common methods are used to measure of Basal Area – fixed area plots and angle count sampling. 1. Fixed area plots require setting out a small area, commonly 50 m x 20 m, and measuring all the trees at breast height, and doing some quick sums. 2. Angle count sampling involves a simple sweep of the forest from a fixed sampling point using a relascope, dendrometer sight, angle gauge, or glass wedge prism. This wooden builders ruler has been shaped at one end to create a shallow angle (usually less than 3 degrees). Standing in one spot, a sweep is made with the wedge held to the eye, and trees are counted as either “in” or “out”. The number of trees is multiplied by conversion factor of the wedge (10 in this case) to estimate basal area. It’s very quick and effective.Basal Area Angle Gauge The two ends fold up and one end (on the right) has been reduced in width to create a shallow angle for the viewer Home made by cutting down a wooden builder's ruler Many forestry students made their own Basal Area Angle Gauges and its thought this may be oneforest measurement, forests commission victoria (fcv)
