ENTS,

Darian Copiz and I met early to measure some trees along the C&O Canal in Maryland. The park contains a long swath of Potomac River floodplain forest and adjacent slopes often of great age. The drive to the parking lot offered views over American sycamore (Platanus occidentalis) dominated forest between the canal and the river.

We went upstream from the lock house in pursuit of the Maryland State Champion Shumard oak (Quercus shumardii). We meandered through the forest marveling at the density of the sycamore flats and impressive shumard oak cohorts. Bitternut hickory (Carya cordiformis), black walnut (Juglans nigra), box-elder (Acer negundo), hackberry (Celtis occidentalis), and an occasional elm (Ulmus sp.) also shared the canopy. We saw lone examples of chinquapin oak (Quercus muhlenbergii) and burr oak (Quercus macrocarpa). Paw-paw (Asimina triloba) and thick exotics populated the understory and native and exotic lianas draped whatever could be climbed.

We measured a few really nice Shumard oaks. One 56” DBH beast had the entire center ripped out yet the remaining side branch still reached 130’. We continued upstream for a bit but were pressed for time to meet up with Gaines McMartin at another site. We hurried downstream to find the champion tree. On the way we measured a nice 17’8” CBH sycamore that was a decent 126.8 feet tall.

We spotted a huge crown in the distance by the river and headed over. Well, it was the “champ” but not even remotely worthy. It was two trees growing side-by-side measured as one. Lame. At least the 123' height was dead-on.

This National Park has a TON to offer and this is just the beginning of lots and lots of searching. My childhood home was near the park and I spent many, many days riding my bike and exploring the forest. I vividly recall huge trees along the Potomac River, which may be one of the unmeasured hot spots of the Mid-Atlantic region.

Species Diameter Height
Shumard 56" 130.0'
Shumard 54" 129.8'
Shumard 43.9" 130.6'
Hackberry N/A 99.6'
Sycamore 67.5" 126.8'
