SLASH WALL PROJECT UPDATE – September 1, 2025
D. Randy Weidner
Now, near the end of the first growing season since the timbering and slash wall project at Mossy Bank Park, a review of the forest’s response seems prudent. Observations were made from various points along the slash wall on the larger of the two plots, and from the north side of the smaller plot. These observations confirm two of the hoped for early benefits of the project: growth of herbal ground cover to stabilize the soil; and exclusion of deer.
A high percentage of the ground in the steeper-sloped large plot was covered with vegetation, and essentially 100% of the flatter smaller plot was covered with green growth. A variety of herbaceous plants were present including: American Burnweed (Erechtites hieraciifolius); Goldenrod (Solidago sps.); Queen Anne’s Lace (Daucus carota); Aster (Aster sps.); Willow-herbs(Epilobium sps.); Purple-flowering Raspberry (Rubus odoratus); Wild Raspberry (Rubus sps.); and Spotted Jewelweed (Impatiens campensis). A more complete list will be generated when more thorough exploration of the site is possible.
By far the most prevalent herb was American Burnweed, also known as Pilewort or Fireweed. This member of the Daisy family (Asteraceae) is a native plant that typically colonizes disturbed areas, often as here, in great abundance. American Burnweed roots stabilize soil from erosion, help reintroduce soil mycorrhizae, and capture nitrogen which ultimately enriches the soil for future plant succession. As other plants move in, Burnweed gradually becomes less prevalent.
In addition to the herbaceous growth, stump sprouts from Red Maple (Acer rubrum), Pin Cherry (Prunus pennsylvanica), Basswood (Tilia americana), Poplar (Populus sp.), Striped Maple (Acer pennsylvanicum), and Sumac (Rhus sps.) were noted within the slash walls. Comparing areas adjacent to, but outside the slash walls, there is virtually no herbaceous growth and tree sprouts, strong evidence that the exclusion of deer will allow forest recovery within the slash walls.
These early observations are certainly encouraging for the ultimate success of the project. Continued monitoring of the sites will occur.
