Trunk injection or endotherapy also known as vegetative endotherapy, [1] [2] [3] is a method of target-precise application of pesticides, [4] [5] [6] plant resistance activators, [7] or fertilizers [8] into the xylem vascular tissue of a tree with the purpose of protecting the tree from pests, or to inject nutrients to correct for nutrient deficiencies.
Thinning from below – this low thinning can be split into 4 Grades: A Grade is a very light thinning, that removes all overtopped trees Kraft crown class 4 and 5. B Grade is a very light thinning that removes overtopped trees and intermediates which are Kraft Crown class 4,5 and some 3s, C Grade and D Grade are a moderate and heavy thinning respectively removing anything that will not lead ...
An increment borer is a specialized tool used to extract a section of wood tissue from a living tree with relatively minor injury to the plant itself. [1] The tool consists of a handle, an auger bit and a small, half circular metal tray ( the core extractor) that fits into the auger bit; the last is usually manufactured from carbide steel.
Rubber tapping is the process by which latex is collected from a rubber tree. The latex is harvested by slicing a groove into the bark of the tree at a depth of one-quarter inch (6.4 mm) with a hooked knife and peeling back the bark. Trees must be approximately six years old and six inches (150 mm) in diameter in order to be tapped for latex.
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.
If wood begins to rot it could create a weak branch connection between the developing suckers and the main tree leading to a possible branch failure. If a tree is unable to compartmentalize the fungi, it may reach the trunk and ultimately kill the tree. [4] Aesthetics is another reason why people hire arborists to top their trees.
Relascope – multiple-use tool that is able to find tree height, basal area, and tree diameter anywhere along the bole; Clinometer – common tool used to measure changes in elevation and tree height; Cruising rod – used to estimate the number of pieces of lumber yielded by a given piece of timber
