The size of the crown is revealed: Why are the branches of some trees even larger than the trunk?
in the measurements of many of the trees, the tree volume is one of the important parameters.Not only for economic reasons, it also involves multiple purposes such as scientific research and sports competitions.Volume measurements of trees can include the volume of trunks or add to the volume of tree branches in higher demand.A variety of measures were measured, from the sum of the volume of tree branches from the trunk to the tree branches, which could be obtained through different measures.
The volumetric measurement of trees not only relates to its size, but also affects the ecology, economic value and biodiversity of the trees.
in volume measurements, commonly used methods include direct geometric measurements via tree climbers, or data collection using telemetry technology.The trees are divided into small sections, each part of it required to measure its length and diameter, and then add the total to draw the whole tree or a certain part of the total volume.Trunks are usually considered to calculate the volume of cone, tray or other geometric shapes.
Direct Volume Measures and Tree Staff
Tree climbers use the height and circumference of the trees.When the Gentlemen reach the highest climbing point, a aggravated rope is directly thrown into the ground.Then, the altitude and diameter of the tree was measured using a rope rope.When the trunk has different diameters, the measurements will be carried out in different heights to ensure the accuracy of data.
Many trees such as giant Sequoia, often compare the volume of trunks to the volume of tree branches.In the case of “President Tree”, a study conducted in 2012 showed that its trunk volume was 45,0000 cubic feet, while the volume was found up to 9,0000 cubic feet.
Especially in the volume of tree branches, in comparison with trunks, is extremely research value, as the dating data reveals the growth pattern and adaptation of the trees.
Volume Challenge of Tree Branch and Tracks
In addition, the volume of tree branches or crowns is similar to a challenge.Not only need to measure the circumference of each dendritic end, but also must be calculated for its length.Usually, measurements focus on the main rough branches, while smaller tree branches may be excluded or estimation.There are treasures such as the treasured oak tree, showing the volume of its trunks of 970 cubic feet, while the dendritic volume is up to 3,850 cubic feet, showing almost four times the amount of tree branches.
in a relatively small tree in the trees, the volume of tree branches accounts for a lower proportion of trunk volume, about only 5% to 10%.
Progress of the technique of the surveying of the tree crown
in the presence of forestry and tree protection, the development of crowns and gauges is increasingly important.Graduate methods allow researchers in three-dimensional spaces to accurately depict the size and location of the tree branches, which provide viable data for long-term ecological monitoring.The process usually requires a number of tree climbers to put in large amounts of time and energy, specifically used to measure the basic diameters and lengths of each tree branch.
Future Outlook
Accessively technologically progresses, telemetry technology such as LIDAR and optical scanning is being carried out, which will make the tree volume measurement more precise and efficient.The ability to observe trees from the angles of different perspectives, providing abundant data, so that I have a deeper understanding of the forest ecology and trees.
