This year I girdled more of the trees around the edges of the Knife Edge Prairie – the wide, flat top of the bluff. I also had to re-girdle many of the birches I had done a few years ago, because they had grown over the old cut.
Another project was cutting and treating small brush – mostly aspen suckers and Gray Dogwood – also in the flat part of the prairie. We mow that area every spring, but it doesn’t ever seem to reduce the number of stems of these two species. I’m experimenting with cutting and treating those stems in a fairly large area – since I can’t tell where the clones start and end. I’m hoping that, over time, I’ll have some effect.
