Eastern larch beetle (ELB) is a native bark beetle that primarily feeds on tamarack larger than 4” DBH. Historically, eastern larch beetle outbreaks in Minnesota were localized and lasted three to six years. However, an outbreak that began in 2001 has been ongoing for 17 years and has affected more...

The exclosure study site is dominated by a mix of northern hardwoods and oak and classified as Central Dry-Mesic Oak-Aspen-Red Maple Forest type (MHc26a). The pre-settlement disturbance regime for this MHc26 native plant community (NPC) was primarily from light surface fire that created partial mortality of the canopy with an estimated rotation of about 75 years. As this is a mesic hardwood community the fires were not catastrophic in scale but with a relatively warmer climate in the central part of the state, ground layer fuels were often dry enough to carry surface fires that provided seedbed and open conditions for regeneration of mid-tolerant species such as red oak. There is current interest in managing these forests with techniques that mimic the natural disturbance patterns created by fire. The use of even-age shelterwood management is often utilized to create large open conditions over time but can prove tricky in maintaining a balance between creating conditions favorable for the species of interest in the face of competition from other species. Site preparation and follow up release techniques can be used to deal with this challenge, but there is a risk that these techniques may have unintended consequences by changing the plant composition of these forests. The pressure from deer herbivory further complicates management.

This silvicultural prescription was designed for a stand at the Cloquet Forestry Center (CFC) that is adjacent to the main entrance and just to the east and south of the primary buildings and grounds area (see Supplemental Content [SC] Figure 4). The stand is split into two blocks, each around...

This case study was conducted in a recently harvested oak stand with thick brush, including invasive buckthorn. Originally dominated by oak, the stand was planted with red pine to transition to a mixed oak-pine stand. Oak naturally regenerated via seed and sprouting. Before planting red pine, the...
