In this episode of SilviCast, we talk with regeneration experts Mike Reinikainen, Roger Bohringer, and Tom Hill about direct seeding—a challenging and often misunderstood approach to reforestation that establishes forests by planting seeds rather than seedlings. Direct seeding can be an economical and effective way to establish new forests, but success depends on getting the details right. We explore seed rates and timing, site preparation, planting depth, and the challenges of seed predation and seed procurement. Because little has been written about the practical application of direct seeding, success requires careful planning, patience, and diligence—as well as a willingness to experiment, observe, and learn from what happens on the ground.
GUESTS ON THIS EPISODE
Roger Bohringer
Assistant Manager, Wilson State Nursery at WI DNR
Roger Bohringer is the Assistant Nursery Manager, tasked with managing the day to day operations at Wilson State Nursery in Boscobel, Wisconsin. Prior to his current duties, he spent several summers in the field all across Wisconsin, looking at new plantings as part of the program’s reforestation monitoring efforts. Roger grew up in the southwest Wisconsin town of Cassville, a two minute walk away from the mighty Mississippi River, and earned a degree in field biology from UW-Platteville in 1992. After graduation he did various LTE stints in Fisheries and Wildlife before falling into Forestry fulltime when he accepted a technician job at Wilson Nursery in the fall of 1998. It was a good fit, and he’s been there ever since.
Tom Hill
Consulting Forester
Tom Hill is a consulting forester based in Southwest Wisconsin, where he’s spent his career helping landowners understand and care for their woods. After a long career with the Wisconsin DNR, in 2022 Tom launched Tom Hill Forestry LLC to spend more time working directly with private landowners across the Driftless region.
Tom’s a self-described “dirt forester,” known for his practical, habitat focused approach and his ability to make forest management feel accessible. He’s worked with thousands of landowners on everything from Driftless woodland management to MFL planning, timber cutting, tree planting and direct seeding. As an avid hunter and lifelong outdoorsman, he brings a real-world understanding of habitat, regeneration, and long-term stewardship.
Mike Reinikainen
State Silviculturist, MN DNR
Mike Reinikainen is MN DNR’s state silviculturist. He is a University of Minnesota alumnus.
