How to Calculate Trees Per Acre By Keith woodlot. For example, if the trees are spaced 10 feet apart in rows that are 15 feet apart each tree has a 150 sq. ft. area within the woodlot. Step 4 Divide the number of sq. ft. in an acre, 43,560, by the number of square feet allotted each tree. For example, if each tree was allotted 150 sq. ft., the number of trees per acre is 290.4.

the subscript stands for "Grundlache," German for basal area, is widely used in Europe and is the symbol recom mended by the International Union of Forest Research Orga nizations (Van Soest et al. 1959) . QMD is oten calculated by the equivalent equation: QMD= where B is stand basal area, n corresponding number of trees, and k is a constant that depends on the measurement .

Given, you have estimates of: Basal area per acre (BAPA, ft 2 /ac) Trees per acre (TPA, #/ac) Avery and Burkhart (1994) give a formula for calculating the quadratic mean diameter of a stand based on BAPA and TPA (see middle of page 290)..

## How To Calculate Stand Basal Area

### Basal area is the area of the cross-section of tree stems near their base, generally at breast height, and including bark measured over 1 ac. or ha. of land. This basal area (BA) is then used to calculate the volume of a tree. Basal area increases as stand size and site quality increases.

- Stand basal area may be better suited to this task than more mechanistic indices such as leaf-area index as it is easy to measure, calculate, and understand, and it may serve as a better index of total (aboveground + below-

- Taking measurements of single trees Instruction sheet A > Stand on the up-slope side of the tree, wrap the tape around the tree at that height. (Be careful not to twist the tape). > Read the circumference measurement from the tape. Record the circumference value in column (a) on Fieldwork sheet A. Precautions > Be sure to read the scale on the tape and record measurement in centimetres (cm
- Stand basal area, denoted by the symbol G, is a very useful parameter for quantifying a forest stand. It may be seen as a summary of the number and the size of trees in a stand.
