When I returned to my hometown neighborhood in northeast Ohio this past August, I was delighted to rekindle my friendship with so many trees that I have known most of my life. There are, of course, the Norway maples and crabapples and blue spruces found in maintained spaces throughout eastern America. One also finds a fair number of sugar maples and Ohio buckeyes. But despite apparently living in a democracy, red oak is king of my neighborhood.
During this visit, I did something that I don’t always do; I looked down. What I saw concerned me. Or, rather, what I didn’t see. Few trees had been planted in a decade, and fewer still will grow into canopy-replacing size. Windstorms were slowly bleeding the neighborhood of its great oak and maple trees, but there were no longer any kings or queens being coronated.

You can find buckthorn just about anywhere these days. It can sneak into the tidiest of gardens, as well as woodlots and forests. It aggressively outcompetes native plants and even tricks wildlife into spreading it to new areas. For example, birds are enticed to eat the berries, but buckthorn berries have a laxative effect, robbing birds of nutrition and ensuring the seeds are spread quickly across the landscape.
There are two species of buckthorn in the state: common buckthorn and glossy buckthorn. The plants are similar in appearance and equally harmful to native ecosystems. Common buckthorn and glossy buckthorn grow to be 20-25 feet tall. Glossy buckthorn has round, glossy leaves with prominent leaf veins and a smooth margin, while common buckthorn has dull green leaves with small teeth on the margin. The branches of common buckthorn will have a small thorn at the tip of the twig. The bark is similar in both species, being rough and flakey. Native cherry and plum trees have similar bark, but buckthorn can be identified by leaf appearance andby cutting into the bark to expose the bright yellow and orange wood underneath.

In 2021, gypsy moth populations increased for a second consecutive summer due to favorable weather conditions. Populations typically increase with an average or mild winter, below average spring precipitation and above average May through June temperatures.
Regional variation in weather can result in significant differences in populations. If weather conditions are favorable again in 2022, the most noticeable increase in caterpillar numbers would likely occur in southern counties, where conditions were driest during this past spring and summer.
Populations experience the fastest growth rate and are first noticed on:
- Dry sites with sandy soil and abundant oak
- Mowed lawns with preferred tree species (oak, crabapple, birch, etc.)
- Large oaks (bur, in particular) with rough bark, especially on or adjacent to mowed lawns

Do you have a tree inventory but have had a hard time keeping it current, or you’re interested in inventorying some trees of your own? The Wisconsin Department of Natural Resources (DNR) is funding several accounts for communities or organizations to edit data within the Wisconsin Community Tree Map, a compilation of tree inventories from around the state. The map shows where trees are located and includes information about each tree, such as diameter, health condition and street address.
