Impact Of Hinge Cutting On Understory Plant Growth?

Reducing Browse Pressure

Hinge cutting deer involves cutting the tree at a 45-degree angle, leaving a portion of the trunk intact. This technique reduces the amount of browse available to deer, forcing them to move to other areas in search of food. By reducing browse pressure, understory plant growth can increase as deer are less likely to feed on young vegetation. A study conducted in the northeastern United States found that hinge cutting reduced deer browse damage by 60%, resulting in a significant increase in understory cover.

Promoting Regrowth

When deer browse is reduced, understory plants are able to regrow more rapidly, leading to an increase in biomass. In areas where deer populations are high, understory plants may be limited to small, shrub-like species that are less palatable to deer. By hinge cutting trees, land managers can encourage the growth of taller, more palatable species, such as oak and maple. This can lead to a more diverse understory community with a greater range of plant species. In one study, researchers observed a 300% increase in understory biomass in areas where hinge cutting was implemented.

Managing Deer Populations

To maintain the benefits of hinge cutting, deer populations must be managed to prevent overbrowsing. This can be achieved through a combination of hunting, fencing, and habitat modification. By reducing deer populations to a level where they no longer threaten understory plant growth, land managers can ensure the long-term sustainability of hinge cutting as a management technique. A general rule of thumb is to maintain deer populations at 10-20 deer per square mile, depending on habitat quality and other factors.
