  2. Tree height measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_height_measurement

    Kelly et al. [44] found that LiDAR at a 20-ft (6.1-m) cell size for the target area in North Carolina did not have enough detail to measure individual trees, but was sufficient for identifying the best growing sites with mature forest and most tall trees. They found that highly reflective surfaces, such as water and roofs of houses sometimes ...

    The number where the right side of the tree lines up with the stick is the approximate DBH of the tree. To measure height, the user stands a fixed distance from the tree, usually 66 feet (20 m) in the United States. The stick is held upright, with the back edge of the stick facing the user.

    In this case a better option would be to measure the standard girth measurement at 4.5 feet above ground level on the high side of the tree and note this in the measurement description. If measuring a mountaintop forest of stunted trees only six feet tall, a girth measurement made at 4.5 feet would be meaningless.

  5. Forest inventory - Wikipedia

    When taking forest inventory the following are important things to measure and note: species, diameter at breast height (DBH), height, site quality, age, and defects. From the data collected one can calculate the number of trees per acre, the basal area, the volume of trees in an area, and the value of the timber. Inventories can be done for ...

    It rarely grows beyond 66 feet (20 m) tall, though the tallest individual recorded was 95 feet (29 m). [6] Pinus pungens is typically around 16 inches (41 cm) diameter at breast height (DBH). The maximum recorded DBH was 34 inches (86 cm). [6] The trunks of Pinus pungens are often crooked and have irregularly shaped cross-sections.

  7. Tree girth measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_girth_measurement

    In this case a better option would be to measure the standard girth measurement at 4.5 feet above ground level on the high side of the tree and note this in the measurement description [13] [17] The height of this measurement point above the standard base point at midslope should also be noted. If measuring a mountaintop forest of stunted trees ...

    Figure demonstrating the ocular trigonometric principles behind the Biltmore stick. Diameter at breast height (DBH) – measurement of a tree's diameter standardized at 1.3 meters (about 4.5 feet) above the ground; Basal area – defines the area of a given section of land that is occupied by the cross-section of tree trunks and stems at their base
