How effective is TSI for increasing deer forage availability?

Question

Accepted Answer

Understanding the Benefits of TSI for Deer Forage TSI involves identifying and removing unhealthy or unwanted trees, typically those with poor growing conditions, disease, or damage. By removing these trees, land managers can create openings that allow sunlight to penetrate the forest floor, promoting the growth of understory vegetation such as grasses, forbs, and shrubs. In a well-managed stand, the removal of 10-20% of trees can create openings of 1-5 acres, depending on the forest density and tree size.
Creating Bedding Areas and Wildlife Sanctuaries In addition to increasing forage availability, TSI can also be used to create bedding areas and wildlife sanctuaries. By strategically placing hinge cuts and tree removals, land managers can create areas with dense cover and minimal human disturbance. These areas can serve as vital resting sites for deer during the day, particularly in areas with high hunting pressure. To enhance their effectiveness, bedding areas and wildlife sanctuaries should be located near natural food sources, such as waterways or agricultural fields.
Hinge Cutting Techniques To maximize the effectiveness of TSI, land managers should employ hinge cutting techniques that minimize damage to the remaining trees. Hinge cutting involves cutting a tree at a 45-degree angle, leaving a small portion of the trunk intact to create a “hinge.” This allows the tree to fall in the desired direction while minimizing damage to surrounding trees. By using hinge cutting techniques, land managers can create openings and promote understory growth while maintaining the structural integrity of the forest stand.
