What Factors Influence Wildlife Return After Timber Harvest?

Habitat Structure and Composition

Habitat structure is critical for wildlife return after timber harvest. The creation of edge habitat through selective harvest techniques, such as single-tree selection or group selection methods, can increase biodiversity and provide a variety of habitats for different species. For example, a 10-acre harvest area with a 20-foot-wide edge can provide 0.4 acres of edge habitat, which can support a variety of plant and animal species. By retaining a mix of tree species, including mast-producing trees such as oak and beech, land managers can provide essential food and cover for wildlife.

Key Resources: Mast Trees

Mast trees are essential for wildlife return after timber harvest, providing a reliable food source for many species. In a study of white-tailed deer habitat, researchers found that deer populations were significantly higher in areas with a high density of oak trees. To promote mast production, land managers can focus on retaining and regenerating mast-producing tree species, such as oak and beech, and maintaining a mix of tree ages to ensure a consistent mast crop. For example, land managers can retain 10-20% of mature mast-producing trees during a harvest and plant new mast-producing tree species in the harvest area.

Edge Habitat and Openings

Edge habitat and openings are critical components of wildlife habitat and can be created through selective harvest techniques. By creating edge habitat, land managers can increase the diversity of plant and animal species in a harvest area. For example, a 10-acre harvest area with a 50-foot-wide edge can support a variety of plant species, including grasses, forbs, and shrubs, which can provide food and shelter for wildlife. Additionally, openings created through harvest can provide critical habitat for species such as white-tailed deer, which use these areas for bedding and movement.
