SilviCast

Eastern white pine is making a comeback, but as experienced field foresters know, much of this second-growth timber can be challenging from a quality standpoint. In this episode of SilviCast, we talk with Rene Germain, professor of forestry at SUNY College of Environmental Science and Forestry, and Sara Dreibelbis, Operations Director at Alliance for a Green Economy. They share insights from their research on assessing and managing eastern white pine, including practical approaches for improving timber quality. You may just find yourself looking at white pine logs a little differently!

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.

Black locust doesn't have many fans among foresters in North America. It's often criticized for growing crooked, spreading aggressively, and producing poor-quality stems. But is the problem really the tree, or is it how we've been growing it? In this episode, Zsolt Keserű, Ph.D., Head of the Department of Plantation Forestry and Senior Research Fellow at the Hungarian Forest Research Institute, University of Sopron, shares how decades of European research and silvicultural innovation have made it possible to grow straight, high-quality black locust timber. Join us for this episode of SilviCast as we talk about the genetics and management practices behind successful black locust plantations, why the species has become such an important hardwood in parts of Europe, and what North American foresters can learn from that experience. If you've written off black locust, this conversation might make you take a second look.

 What tree begins life looking more like a tuft of grass, survives repeated fires for years on the forest floor, and then suddenly bolts toward the canopy in a remarkable growth spurt? The longleaf pine (Pinus palustris) is one of the most unique and ecologically important tree species in North America. Once dominating the coastal plains of the southeastern United States, longleaf pine forests have been reduced to less than 5% of their historic range. Yet these forests remain among the most biologically diverse ecosystems on the continent. In this episode of SilviCast, we explore the fascinating life history of longleaf pine and the silvicultural practices being used to restore these iconic forests. Join us for a conversation with Steve Jack, Executive Director of Boggy Slough Conservation Area, who shares insights from decades of longleaf pine restoration work across the southern United States. 

Guest on the Episode:
Steve Jack, Ph.D.
Director of the Boggy Slough Conservation Area

Good silviculture isn’t just about knowing the science—it’s about building strong partnerships. One of the most critical relationships in forestry is the collaboration between foresters and loggers. Successfully marking a timber sale, for instance, means understanding not only the forest but also the equipment and capabilities that will bring the prescription to life. In this episode of SilviCast, we dive into the world of modern logging equipment used across eastern North America. Joined by Carl Lockhart, Forestry Products Consultant with John Deere, we explore how today’s machines shape on-the-ground decisions—and why aligning knowledge between planning and execution is key to getting silviculture right.

Managing forests for carbon—and navigating emerging carbon markets—can feel overwhelming, especially for family forest owners managing smaller parcels. So how can landowners with just a couple forty-acre parcels participate in these opportunities? And what does carbon-enhanced silviculture actually look like at that scale? In this episode of SilviCast, we sit down with Brittany VanderWall, Lynn Riley, and Richard Campbell from the American Forest Foundation to break down the essentials of the Family Forest Carbon Program. They share practical insights on how family forest owners can access carbon markets, implement climate-smart forest practices, and make the most of their land—without needing thousands of acres to get started.

 Many of us in forestry remember the spotted owl controversy of the 1980s — a pivotal moment that put old-growth forests of the Pacific Northwest in the national spotlight. But what’s less often told is how that same moment sparked a wave of old-growth research here in the Lake States, launching more than three decades of work to better understand how old-growth northern hardwood forests differ from those we actively manage. In this episode of SilviCast, we sit down with Julia Burton, Associate Professor of Silviculture at Michigan Technological University, to explore what we’ve learned from that research — and how those insights are shaping the future of northern hardwood forest management.

Foresters know degraded forests all too well. You’re out on a woods-walk with an enthusiastic landowner, but your eyes go straight to the poor growing stock, invasive plants, and eroded forest soils – the fingerprints of past degradation. Regardless, you set about the complex task of developing a prescription that will nudge this forest towards a brighter future. Foresters don’t always think of themselves as restorationists, but in many ways, the tools of silviculture are the tools of restoration. In this episode of SilviCast, we dive into the science and practice of forest restoration with John Stanturf, visiting professor at the Estonian University of Life Sciences and Senior Forest Restoration Specialist with InNovaSilva. With more than 30 years of experience researching forest restoration in both temperate and tropical forests around the world, John brings a global perspective to the question of what it means to restore a forest.

A dead tree is not truly dead. As trees die, they become snags, downed logs, and eventually return to the soil as organic matter. Along this journey, they host a wide range of organisms and play essential roles in forest ecosystems. How foresters think about and manage dead trees can be just as important as how they manage living ones. In this episode of SilviCast, we explore the concept of morticulture - the intentional management of deadwood in forests. Join us for a conversation with Mark Harmon, professor emeritus in the Department of Forest Ecosystems and Society at Oregon State University. Dr. Harmon has spent decades researching tree mortality, wood decomposition, and the management of coarse woody debris in our forests.
