This case study is a good example of an 80 to 100 year old oak stand successfully harvested and regenerated to a mixed hardwood stand with a good oak component through stump sprouting (coppice). Beginning in the mid to late 1980s, Minnesota DNR undertook a strategy of selecting some younger red oak...

The purpose of this case study is to analyze the differences in paper birch regeneration between a shelterwood versus a seed-tree method.The Minnesota DNR, in the Cloquet Area, doesn’t usually manage exclusively for paper birch due to the presence of aspen in most stands. Therefore, birch seed tree...

This case study is an assessment of 2019 stand conditions on a site that was treated in 1989 with a unique oak regeneration precription using mechanical site preparation. It has been challenging over the years to find practical, affordable cultural methods to consistently regenerate red oak on...

This was a variable density thinning treatment in mixed pine-hardwoods that turned into a variable retention harvest with a regeneration component in gaps. Some of the gaps were planted with bur and red oak by The Nature Conservancy for an assisted migration for climate change study (Etterson et...

This site was one of the first final harvests of natural origin red pine (NORP) on School Trust land in the Hibbing area. This case study looks at the use of both natural and artificial regeneration practices to regenerate a NORP site in a manner that mimics the structure and diversity of a stand...

Tree direct seeding and natural volunteer seeding can be an effective means of reforesting sites. This site was dominated by reed canary grass and was a former hay field. The site was direct seeded in the fall of 2017 after site prep to control competing vegetation. Acorns, walnuts, and dogwood...

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 project was developed and implemented by an inter-disciplinary team. Multiple natural resource objectives were in play as well as trying to work together to learn how to better layout treatments that are practical for commercial harvest, prescribed burning, and reforestation operations. We...
