When preserving a tree at a construction site, where should a protective fence be placed?

When preserving a tree at a construction site, the protective fence should be placed approximately the same diameter as the canopy. This placement is essential for several reasons related to the health and longevity of the tree.

The canopy represents the area where the tree's branches spread out and where leaf growth is concentrated. This is not only crucial for photosynthesis but also indicates the extent of the tree’s root system, which often mirrors the canopy in size. Protecting this area ensures that the roots, which are vital for nutrient uptake and stability, are safeguarded from soil compaction and physical damage that can occur during construction activities.

Additionally, placing the fencing according to the canopy helps prevent disturbances to the soil that could affect the tree’s health, such as changes in drainage patterns or the introduction of harmful substances. By maintaining a buffer zone around the entire area covered by the canopy, you support the tree's overall ecosystem and mitigate the impact of construction on its survival.
