I've spent a fair bit of time this past month cutting back the buckthorn in the 1995 area. It had half taken over the understory so I decided to cut them back in areas to give other trees and bushes a chance. In doing so I've made quite large piles of twigs and branches and I wonder if it is good for the other plants to have such piles decomposing around them. Here I've made a crude experiment where I've left a pile of buckthorn on some grass outside the forest. The above image was on June 4th when I first piled it there. The image below is today the 30th of June after it had been sitting there for a month of mostly dry weather. I'll check back on it and see how the grass under the pile survived at the end of summer. If buckthorn as it decomposes gives off toxic chemicals perhaps the grass will die back from the pile of twigs.
