It pays to be observant! Ogijewski, a forest scientist working in Russia in the early 1900s observed that oaks sometimes regenerated in small clusters where wild boars disturb the forest floor. From this simple observation he developed a reforestation method called cluster planting, the planting trees or seeds in tightly-spaced, small functional groups. The method caught on in Europe and is now practiced as a way to decrease planting costs and restore stand diversity. In this episode of...

It’s not worth saying anything unless it’s worth taking a long time to say, to paraphrase Treebeard in The Lord of the Rings. And sometimes you need to play the long game if you’re a research forester too. Long-term silvicultural studies are surprisingly rare, but extremely valuable. That is why a recent paper on six decades of selection cutting results got our attention. The Cutting Methods Study is a long-term investigation of cutting systems in second-growth northern hardwood stands on the...

Sometimes foresters in eastern North America may feel as if they are in a Lemony Snicket novel, with chestnut blight, spongy moth, Dutch elm disease, and emerald ash borer creating a continuing series of unfortunate events. Emerald ash borer or EAB is one of the most recent invasive pests with the potential to eliminate an entire tree species. And foresters have many questions on how to manage EAB impacted stands and what they can do to help maintain ash trees as a component of our fore...

As foresters we spend a great deal of time looking up, to evaluate forest composition, structure and growth. The story below ground is equally as interesting however, with complex interactions between soils, nutrients, water, roots, and a host of other flora and fauna. As they say in Vegas, what happens below ground, stays below ground! Everything here is more difficult to study. This is particularly true about a class of organisms critical to trees, mycorrhizal fungi. We know that mycorrhiza...

No matter how you define it, old-growth forests are scarce as hen’s teeth in the eastern United States. More than 99% of our forests are second growth. While we can’t speed up time, we can speed up the development of old-growth characteristics through creative silviculture. Join us on this episode of SilviCast as we talk with Paul Catanzaro, Professor and State Extension Forester at the University of Massachusetts - Amherst, about a range of silvicultural techniques to restore old-growth char...

The official Society of American Foresters' definition of silviculture describes it as both an art and science. Are foresters both artists and scientists? What role does creativity play when developing a silvicultural prescription or setting up a timber sale? In forestry school we learn the foundational sciences of silvics, forest ecology, soils, wildlife, and water. And through experience and time spent in the forest we learn how to best apply that science to particular stands and site condi...
