High pruning involves the careful removal of all branches from a tree, reaching greater heights than traditional brashing. This technique is particularly advantageous for final crop trees that show promise for producing valuable saw logs. Typically, high pruning is applied to broadleaf species with long growth cycles, such as ash, oak, walnut, beech, and sycamore, which can take up to 150 years to mature. Additionally, some exceptional conifers, like Douglas fir, Scots pine, and larch, may also undergo this pruning process.
Determining the desired length of clear stem is at the discretion of the woodland owner. Common high pruning heights range from 4 to 10 meters, facilitating better access to the treeβs upper sections while enhancing the overall health and growth potential of the tree.
The pruning is generally performed from the ground using specialized tools, such as a high pruner or pole saw. A pole saw is an extended version of a brashing saw, created to reach higher branches effectively. By allowing for the addition of detachable handle sections, often made of lightweight aluminum, these tools enable users to prune at the required height comfortably.
Another commonly used tool, the high pruner, works differently by employing a lopper mechanism activated by a cord that severs branches cleanly at height. While these hand tools can be effective, they often require significant physical effort, making the task somewhat labor-intensive.
To alleviate some of the physical demands associated with high pruning, the industry has seen advancements in technology, particularly the development of powered high pruners. These modern tools resemble strimmers but are equipped with hydraulically powered chainsaws at their ends. Many are designed to be worn on a harness, enhancing user convenience and reducing fatigue. Older powered versions may feature the engine on a backpack, allowing for easier maneuverability and extended reach.
High pruning is an important practice for woodland owners and tree caretakers, promoting the production of high-quality timber while ensuring that trees can thrive and mature effectively. With the right techniques and tools, you can elevate the health of your trees and maximize their potential. π³πͺ
