S.5 Ep.1: Putting the Old in Old-Growth

SilviCast ·

2024/01/02

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

S.4 Ep.11: The Art of Silviculture

SilviCast ·

2023/12/12

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

S.4 Ep.10: White Oak, Whiskey, and Wildlife

SilviCast ·

2023/12/06

If you're a whiskey enthusiast, you are probably aware of a lesser-known federal law that requires all bourbon (an American whiskey) to be aged in a “charred new oak container." And those containers or casks are made almost exclusively from white oak (Quercus alba). But white oak has been popular long before the recent rise in whiskey-sipping Gen Xers! It is simply hard to overstate the importance of this tree species to forest products, wildlife habitat, and ecosystem services. In fact,

Good silviculture is about using the best available science, along with the experience and local knowledge we accumulate in the field. What if we practiced forestry in an area for not only one lifetime, but for generations upon generations. Imagine the knowledge-base we could draw from to guide our silviculture! Indigenous peoples have been managing forest vegetation for various purposes for generations, accumulating a great understanding of how forest ecosystems work, sometimes referred to as

S.4 Ep.8: ICO ICO a Nae

SilviCast ·

2023/09/01

They say if you want forest heterogeneity, just get a larger group of foresters to mark the stand. While it is true that not every forester marks the same, it is often challenging if we want to intentionally create spatial variability. Especially if we want to emulate spatial patterns that would be typical for a specific forest type and natural disturbance regime. The ICO method (which stands for individuals, clumps, and openings) is a stand-level tool developed in the western US to help foresters

S.4 Ep.7: The Cedar Club

SilviCast ·

2023/08/01

Foresters love a challenge! And one such challenge in eastern Northern America has always been northern white-cedar (Thuja occidentalis). A both ecologically and commercially valuable tree species that can be slow-growing, tricky to regenerate, and highly susceptible to deer browse. Join us on this episode of SilviCast as we introduce you to the Cedar Club, a passionate group of forest practitioners and researchers who have been tackling the cedar management question for the pat 23 years.

S.4 Ep.6: Green Side Up

SilviCast ·

2023/07/01

It seems that every young forester may have heard the old adage “green side up" tossed at us half-jokingly while learning to plant our first tree seedlings, almost as if to say "don't overthink this one kid." As experienced foresters we soon learn that achieving tree planting success is a whole lot more complicated. There are critical variables from stock type to site preparation to planting technique. If the world is going to get the trillion tree initiative right, all of these

SilviCast ·

2023/06/01

We all know that oak and fire go together like peanut butter and jelly. What we have been missing is the practical knowledge of where, when, and how to apply fire in oak ecosystems. There are few who have contributed more to this knowledge base than Dr. Patrick Brose from the US Forest Service's Northern Research Station. Dr. Brose's research has developed key silvicultural applications of fire to regenerate and sustain oak forests and woodlands. Join us on this episode of SilviCast as we

S.4 Ep.4: How Now Brown Cow?

SilviCast ·

2023/05/01

Foresters have been warning landowners for years about the potentially damaging impacts of cows in their woods. So it is not surprising that we raise an eyebrow when conversations start about intentionally integrating livestock and forests. In this episode of SilviCast we explore the management practice known as silvopasture, or the intentional integration of trees, forage, and livestock. Join us as we discuss what silvopasture is and is not, with Rich Straight, Technology Transfer Leader at the

2023/03/29

Business is booming if you own a commercial sugar bush! As forest managers, this means more and more of us are hearing from landowners interested in starting or maintaining a sugar bush. Unfortunately, if you are like us, you did not learn about maple syrup in forestry school. This episode's guest, Mark Isselhardt, Extension Maple Specialist with the University of Vermont, helps us unpack the fundamentals of sap production, sugar bush management, and how the industry has changed in the 21st

S.4 Ep.2: Climate Castaways

SilviCast ·

2023/03/02

Trees have had to migrate for millennia due to changes in climate. However, the pace of climate change today is far greater than historical tree migration rates, and land use changes have created new barriers to species movement. This has foresters and land managers thinking about the need for human-assisted movement of tree seed or seedlings to ensure that forests remain well-adapted to climatic conditions, a concept referred to as forest-assisted migration. In this episode of SilviCast we explore

S.4 Ep.1: The King's Pine

SilviCast ·

2023/02/06

Eastern white pine is an iconic tree of cultural and historical importance to eastern North America. The “great pineries” in this corner of the world were heavily exploited during the 19th century for everything from ship masts to lumber that built growing cities. But white pine has been quietly making a recovery over the past 150 years, and with that recovery white pine silviculture has continued to evolve.

S.3 Ep.10: Ecological Silviculture - A Natural Model

SilviCast ·

2023/01/04

One of the most interesting aspects of silviculture is that our understanding keeps growing. We look to old approaches, new research, and field practice to better manage our forests for a host of societal needs. And perhaps there is no better place to look than how these forests function in the natural world – a natural models approach. This is the basis of ecological silviculture and the tools behind emulating natural disturbance. Join us for a conversation with Dr. Tony D’Amato from the

2022/12/14

Interfering vegetation, be it native or invasive, is a real headache for foresters. Sometimes we wind up wishing for one more tool in the toolkit when none of the current ones seem to fit. Luckily, some foresters are innovating and exploring new options. Some are turning to the oldest tool we have: grazing. In this episode we explore the world of targeted goat grazing with Brooke Hushagen and Greg Haak of HaakHagen Goat Grazing LLC. To earn CEU/CFE credits, learn more, or interact with SilviCast,

Wildlife habitat is the primary goal for many forest landowners, and in particular forest bird habitat. Silviculture treatments have great potential to provide quality habitat for birds if we know what to look for. Join us on this episode of SilviCast as we take a walk in the woods with Mike Demchik, Professor of Silviculture at the University of Wisconsin – Stevens Point, while we discuss how to recognize the bird habitat elements that are missing in a woods and better integrate those elements

In this second episode of our two-part series on forest carbon, we explore ways to enhance carbon storage and sequestration through silviculture. Whether it is through our choice of silvicultural system, how and when we employ intermediate treatments, or our tree retention practices, we will discuss how we can impact forest carbon and a host of other stand objectives.

S.3 Ep.5: Carbon, WHAT?!!

SilviCast ·

2022/06/24

In forestry school we learned about photosynthesis; the process by which trees use sunlight, water, and carbon dioxide to form sugars and oxygen. But most of us did not learn much about how to purposely manage forest carbon once it’s in the ecosystem. In this two-part series on forest carbon, we will explore ways to enhance carbon storage and sequestration through our silviculture. In today’s episode (Part 1) we talk with Alexandra Kosiba, Ph.D., the first state climate forester with the Vermont

SilviCast ·

2022/05/26

Necessity is the mother of invention, even in silviculture. Foresters in the eastern US often struggle with regenerating trees due to severe deer browse. Yet mitigating solutions, like fencing and tree shelters, are costly and problematic. What if you could use a resource that is abundant, on-site, and cheap to keep the deer out? On this episode of SilviCast we explore the innovative strategy of "slash walls," or the use of logging residues to form deer barriers around regenerating

Fine hardwood veneer logs represent the pinnacle of log quality and timber value, with prices up to 10 times the price of grade 1 sawlogs. However, trees of this quality can be rare as hens' teeth! Are there practices foresters can use to improve the odds of producing veneer quality logs? Are there mistakes we make while managing stands with veneer potential?
