A crucial forestry tool

Thinning is often the most important thing you can do to influence the growth and health of your forest. Proper spacing and thinning can reduce overcrowding and relieve tree stress. This helps maintain the health and vigor of your forest. Thinning can reduce fire hazards, generate revenue, and increase the value of remaining trees. From an aesthetic perspective, thinning helps create a more open forest stand, which often increases the likelihood of wildlife through improved forest habitat.
