The DBH of this tree is 10 cm. What is crown width?

DBH: The breast height in China and most countries is 65438+ 0.3m above the ground. DBH, also known as trunk diameter, is only used for measuring trees.

Crown width: in garden plots, it refers to the average width of trees (seedlings) in the north-south and east-west directions, with similar diameters. If it is too high to measure, you can measure and project it.

Crown width refers to the range of tree crown, which is specially used for tree survey. In strict measurement, the projected length of the crown through the trunk under the tree should be measured with a tape measure, and then the projected width of the crown through the trunk should be measured perpendicular to the length.
