What does a log grader do?
Log graders and scalers are responsible for inspecting and estimating the value of logs or pulpwood.

They grade the logs and estimate their marketable content.

This degree may help workers get a job. Courses may include field trips to observe or participate in logging activities.
What are the three most common methods used for log scaling?
There are three common geometric- based methods of scaling hardwood logs: Doyle, Scribner, and International ¼-Inch (Freese 1973, Bond 2011). The Doyle rule estimates lumber recovery based on log diameter, length, residue, and saw kerf.
How big does a tree have to be to log?
In most cases, properties 20 acres and larger are an ideal size for logging timber (again, depending also on the quantity, size, and types of the trees on the property).
What does DBH stand for?
DBH means the diameter of each tree is measured at “breast height”, defined as 1.35m up from the highest point of ground at the tree’s base (See the Tree Circumference Guide for some pictorial examples). DBH measurements can be used to estimate the volume, biomass, and carbon storage of trees.
How do you use a Biltmore stick?
- Hold stick level against tree 25” from eye and 4 ½’ above ground on uphill side.
- Move the stick to the left or right until your line of sight to the left hand side of the tree crosses at the left hand end of the stick.
- To determine DBH, sight on the right side of the tree without moving your head.

What is the most common diameter measure of standing trees?
Diameter at breast height
How is DBH calculated?
To measure a tree’s DBH, first locate a tree in your community. With a ruler or measuring tape, measure from the ground to a point on the tree trunk 4 1/2 feet from the ground. This height is considered “breast height.” At this height, measure around the tree trunk to get its circumference.
Which measurement is the longest?
Kilometers
What are the things we can measure?
We can measure many different things, but mostly we measure Length, Area, Volume, Mass and Time.
How do you convert?
Summary
- Write the conversion as a fraction (that equals one)
- Multiply it out (leaving all units in the answer)
- Cancel any units that are both top and bottom.
