Norway Spruce

Over 26,000 web pages tell us about Old Tjikko, including the usually reliable National Geographic. As is common for such stories on the internet, […]

When is a flower not a flower?

Many trees are full of showy flowers at this time of year. A close look at these flowers can be quite rewarding. Flowering dogwood is one of our most popular flowering trees, but those beautiful white blossoms hide a secret. Take a close look at a dogwood tree and you will see that the showy […]

Street Lights and Tree Growth

Urban trees live with all kinds of stresses that their forest cousins do not – road salt, soil compaction, lawn mower strikes. They also live in a different light environment, one in which it is never completely dark.  Spend the night deep in the woods and the only light you will see is from the […]

The Wolf Trees of Nashville

When you hike through the woods in Nashville, you don’t expect to encounter wolves. If you keep your eyes open, though, you may see some wolf trees. Foresters used the term ‘wolf tree’ to indicate a very large tree with a broad crown and a short main stem.  These trees were considered wolves because they […]

How Old is that Tree?

Everyone wants to know how old a particular tree might be. We will discuss this complicated and important subject in two stories. This month we will talk about unitary trees, and next month we will tackle the complex problem of aging clonal trees.   A unitary tree is like a person – a single, integrated organism. […]

Young Woodland Pastures

Those who have read my book or heard my presentations know that one of our major concerns about the future of our rare and ancient woodland pastures is the failure of trees to reproduce. With trees succumbing to age, lightning and poor management, the population of ancient trees is declining. While we are constantly on […]

Woodland Pastures of Clark County

Clark County Kentucky is in the Inner and Outer Bluegrass (map). The Outer Bluegrass farms are on steeper hills than in the Inner Bluegrass and are primarily cattle farms.

How to make beer in 1779

Imagine that you are a settler in the Bluegrass in 1779, the year Lexington was established.  There is no shortage of game, and wild plants. But what do you do if you want a good beer? West Sixth Brewing was not open yet, so what was the thirsty settler to do?  You could make your […]

A Deep Green Autumn

A deep green autumn is rare in Kentucky. By this time of year, our trees usually look forlorn and bedraggled. Dry summers, high temperatures, insects and diseases all take their toll.  Not in 2015, though. Our frequent rainfall and cool temperatures have allowed many trees to maintain lush green leaves and to continue growing. Some […]

Quercus sumatrana in Sumatra

How many trees species?

When I worked in Borneo, I was fascinated by the immense diversity of trees in the jungles where I worked, even though I could only identify a few species. I did not even know how many different trees I was seeing. They look so much alike, with some exceptions, that I could walk by a […]

The Great Flush of 2015

Have you seen the Great Flush of 2015?  In Central Kentucky,  trees are growing very fast right now, producing new growth that is noticeable for its pale green or yellow colors.  Late flushes are complicated responses to changes in soil moisture. This is the first of several stories about the Great Flush of 2015, but […]

Unsafe tree work in our parks

While walking through Kirklevington Park, I saw two groups of Lexington city workers doing their jobs. On one side of the street, a group of solid waste workers were collecting trash. They were wearing high-visibility safety vests, helmets and work boots. On the other side of the street, several Parks & Recreation employees were cutting […]

American Sycamore: A Crown Fit for a King

Just north of the charming downtown district of Lebanon, OH, an area with well-known buildings and historical markers spanning over two centuries, a different kind of historical marker recently caught my eye. In the expansive front lawn of an elementary school building, I beheld two massive American sycamores towering over the manicured lawn. As any […]

Under the spreading chestnut tree

Many of us learned the great Henry Wadsworth Longfellow poem The Village Blacksmith in school, which begins: UNDER a spreading chestnut tree The village smithy stands; The smith, a mighty man is he, With large and sinewy hands; And the muscles of his brawny arms Are strong as iron bands. As a forestry student, I learned that […]

New leaves on a defoliated bur oak

A couple of weeks ago, we told you about a magnificent, ancient bur oak that was suddenly defoliated overnight.  We said that it would recover quickly and that we would update you. With 10 days of mild weather, the tree has leafed out very quickly.  Most trees maintain large reserves of starch and protein in […]

Dead white ash

Dead Trees and the Great Curve

This is the year of death in central Kentucky.  The emerald ash borer has been slowly expanding its population, and has now reached the point of mass destruction. You can see dead and dying trees all over town, most of which have died this spring.  From here on, barring some miraculous change in ash borer […]
