  2. Tree measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_measurement

    However, this would represent one tree exhibiting all three maxima- an unlikely possibility. However, the apparent size of a tree can be realized by ranking the cumulative values against the theoretical maximum. A tree scaling close to 300 would suggest that it was nearly the largest specimen theoretically possible based on currently known maxima.

  3. Tree girth measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_girth_measurement

    The Tule tree has a diameter of 38 feet 1.4 inches (1,161.8 cm) as measured by tape wrap, but because of its irregularity a cross-sectional wood area expressed as a circle gave an effective diameter of only 30 feet 9 inches (937 cm). The base of the tree was mapped in three dimensions using a frame mapping technique.

  4. Tree height measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_height_measurement

    American Forests, for example, uses a formula to calculate Big Tree Points as part of their Big Tree Program [3] that awards a tree 1 point for each foot of height, 1 point for each inch (2.54 cm) of girth, and ¼ point for each foot of crown spread. The tree whose point total is the highest for that species is crowned as the champion in their ...

  5. Diameter at breast height - Wikipedia

    en.wikipedia.org/wiki/Diameter_at_breast_height

    Measurement of tree circumference, the tape calibrated to show diameter, at breast height, making sure that the tape is perfectly level and that the tape is not kinked, so as not to skew the reading of the diameter. Diameter at breast height, or DBH, is a standard method of expressing the diameter of the trunk or bole of a standing tree.

  6. Tree volume measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_volume_measurement

    Tree volume is one of many parameters that are measured to document the size of individual trees. Tree volume measurements serve a variety of purposes, some economic, some scientific, and some for sporting competitions. Measurements may include just the volume of the trunk, or the volume of the trunk and the branches depending on the detail ...

  7. Tree allometry - Wikipedia

    en.wikipedia.org/wiki/Tree_allometry

    Allometry studies the relative size of organs or parts of organisms. Tree allometry narrows the definition to applications involving measurements of the growth or size of trees. Allometric relationships often are used to estimate difficult tree measurements, such as volume, from an easily measured attribute such as diameter at breast height (DBH).

  8. Tree crown measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_crown_measurement

    American Forests, for example, uses a formula to calculate Big Tree Points as part of their Big Tree Program [3] that awards a tree 1 point for each foot of height, 1 point for each inch of girth, and ⁠ 1 / 4 ⁠ point for each foot of crown spread. The tree whose point total is the highest for that species is crowned as the champion in their ...

  9. List of superlative trees - Wikipedia

    en.wikipedia.org/wiki/List_of_superlative_trees

    The girth of a tree is usually much easier to measure than the height, as it is a simple matter of stretching a tape round the trunk, and pulling it taut to find the circumference. Despite this, UK tree author Alan Mitchell made the following comment about measurements of yew trees: The aberrations of past measurements of yews are beyond belief.
