Quick Answer
Improper bark harvesting techniques can lead to bark damage, reduced plant survival, and decreased fiber quality. This can result in a shorter lifespan for the plant, reduced fiber yield, and decreased overall utility of the harvested material.
Damage to the Tree
When bark is harvested improperly, the cambium layer, which is responsible for the production of new bark and wood, can be damaged. This can lead to the death of the tree or the development of cankers, which are lesions that can weaken the tree and make it more susceptible to disease and pests. To minimize damage, harvest bark in the off-season when the tree is dormant, and avoid removing more than 25% of the bark in a single year.
Impact on Fiber Quality
Improper harvesting techniques can also damage the fibers within the bark, resulting in lower quality fibers that are more prone to breakage. This can make it more difficult to work with the fibers and can reduce the overall utility of the harvested material. To minimize damage, harvest bark when it is moist and pliable, and use a technique called “fluting” to loosen the fibers before removing the bark.
Best Practices for Bark Harvesting
To ensure that bark is harvested in a way that minimizes damage to the tree and the fibers, it is essential to follow best practices. This includes harvesting bark in the off-season, removing no more than 25% of the bark in a single year, and using a technique called “fluting” to loosen the fibers before removing the bark. It is also essential to use the right tools for the job, such as a drawknife or a bark scraper, and to harvest bark in a way that minimizes waste and reduces the risk of damage to the tree.
