Property owners, especially properties who have trees on any part of the land, have a legal obligation by making sure that those trees are safe. When the area is open to the public, it is more important to ensure that trees do not impose hazard to the community’s health and safety. Also, some trees might need to undergo some process like bracing to make sure that they are safe.
One of the most recognized methods of acquiring all the necessary information about trees is called tree surveys. A variety of data is gathered during a tree survey such as species, age, number, and location. If a development inspection is needed for a potential construction site, the survey will be conducted together with the British Standard BS5837:2012 for tree surveys. All the information relevant to the dimensions, presence of diseases, infestations, health, and damage should also be recorded in the tree survey.
Today’s article will serve as a useful guide for your reference on how tree survey works.
Tree Survey: Pre-Planning
It is essential to time the survey detects specific infestations and possible diseases. Also, make sure that no trees are missed out during the survey. For you do this, it’ll require a pre-planning procedure. Generally speaking, there are four identified methods of dividing an enormous package of land into specific areas.
- Complete Survey – this is the easiest and understandable type of survey. It involves trees in an area depending on the species being examined
- Radius Survey – for broad surveys of huge trees, it is recommended to create a rotational survey area within a specific radius and later, will extend it for a few meters away at that time
- Line Transects – this process utilizes a series of traverse lines that have even spaces. As you walk along each path, you should check trees from your left to right
- Quarter Point Transects – locate the diseased trees and then walk in a straight line starting to north, south, east, and west, record all the infected trees as you go from another direction.
Tree surveys are commonly conducted from the ground. In other scenarios, you may need to go higher to check the crown and cavities at the top of the trees.
