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 refor
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 su
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 o
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
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
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
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 whi
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. Ima
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. Especial
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,
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 le
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
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
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 abou
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 fores
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 b
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
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 n
Remember the natural regeneration triangle? Natural regeneration needs a seed supply, an environment conducive to seed germination, and a suitable seedbed. But sometimes it's difficult to get the right seedbed, especially when natural disturban
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 S
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 tre
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 ec
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. W
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 imp
Savannas, woodlands, and other open forest systems once occupied vast areas of North America where fire disturbance, at least in part, shaped their structure and composition. Many of those acres have been lost since the advent of fire exclusion
