Basal area is the cross-sectional area of trees at breast height (1.3m or 4.5 ft above ground). It is a common way to describe stand density. In forest management, basal area usually refers to merchantable timber and is given on a per hectare or per acre basis. If one cut down all the merchantable trees on an acre at 4.5 feet (1.4 m) off the ...
A dog in a wire crate strapped into a car for safe traveling. Crate training is the process of training a pet to tolerate confinement in a dog crate or cage. Crate advocates often claim that dogs are "den-dwelling" animals and that a crate can become a "den" substitute and a familiar and safe location for the pet. Most puppies can eventually ...
When stocking, a tree's basal area is measured. The basal area is a cross-sectional area of the stump taken about 4.5 feet (1.4 m) above the ground. [7] The equation for calculating the basal area of trees in a stand is Basal Area = 0.005454 DBH 2, where DBH is the diameter of the tree at the aforementioned measuring height. [7]
One variety of wire crate A variety of a soft crate. A dog crate, dog cage, or kennel is a metal, wire, plastic, or fabric enclosure with a door in which a dog may be kept for security or transportation. Dog crates are designed to replicate a dog's natural den and as such can provide them with a place of refuge at home or when traveling to new ...
where BA is stand basal area, n is the number of trees, and k is a constant based on measurement units - for BA in ft 2 and DBH in inches, k=0.005454; for BA in m 2 and DBH in cm, k=0.00007854. References
Basal area and density are plotted against one another and quadratic mean diameter lines are plotted through the plot. The diagram itself is a plot of the natural logarithm of the volume or yield against the natural logarithm of stems per acre. Just like a stocking diagram, the A-line, B-line, and C-line are plotted.
The above equation is an expression for computing the stand density index from the number of trees per acre and the diameter of the tree of average basal area. Assume that a stand with basal area of 150 square feet (14 m 2) and 400 trees per acre is measured. The dbh of the tree of average basal area D is:
A chart (sometimes known as a graph) is a graphical representation for data visualization, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart". [1] A chart can represent tabular numeric data, functions or some kinds of quality structure and provides different info.
