The President Tree (Sequoiadendron giganteum) [3] was measured in 2012 to have a trunk volume of 54,000 cubic feet (1,500 m 3) of wood and a branch volume of 9,000 cubic feet (250 m 3) of wood in the branches. In this giant tree the branch volume was only 16.7% that of the trunk volume.
Tree volume measurements may include just the volume of the trunk, or may also include the volume of branches. [25] Volume measurements can be achieved via ground-based or aerial methods. Ground-based measurements are obtained by the use of a monocular w/reticle, laser rangefinder, and a clinometer.
Volume can be calculated from the metrics recorded in a plot sample. For example, if a tree was measured to be 20m tall and with a DBH of 19 cm using previous measured tree data a volume could be approximated according to species. Such a table has been constructed by Josef Pollanschütz [4] in Austria. Volume of tree = BA X h x f pollanschutz
The Washington Tree (not listed above) was previously arguably the second largest tree with a volume of 1,354.96 m 3 (47,850 cu ft) (although the upper half of its trunk was hollow, making the calculated volume debatable), but after losing the hollow upper half of its trunk in January 2005 following a fire, it is no longer of exceptional size.
A volume table is a chart to aid in the estimation of standing timber volume. These tables are based on volume equations and use correlations between certain aspects of a tree to estimate the volume to a degree of certainty. The diameter at breast height (DBH) and the merchantable height are used to determine the total volume. Difficulties ...
There are different tree species compositions in each region in the world and most of those regions have at least one equation that estimates tree volume from DBH. Research and the application of forest allometry have meshed over time to develop these quick equations to accurately estimate how much volume a particular forest stand holds.
Volume of trunk: 530 m 3 (18,600 cu ft) [2] Hyperion is a coast redwood ... The tree has grown since then to reach 116.07 metres (380.8 ft) recorded in 2019.
The mean annual increment (MAI) or mean annual growth refers to the average growth per year a tree or stand of trees has exhibited/experienced up to a specified age. For example, a 20-year-old tree that has a stem volume of 0.2 m 3 has an MAI of 0.01 m 3 /year.
