I've mentioned many times this winter, the use made by wildlife of Manitoba maple seeds. I know a lot of people dislike these trees. I'm not sure why, perhaps because they produce abundant seeds which sprout freely and grow quickly. But, they are native to Canada, as native as our purple coneflowers and other prairie plants that we seem happy to grow as natives in our gardens! At any rate, this tree has been very thoroughly girdled by voles, and like all the others also girdled in the past, will die. The voles have done a good job controlling Manitoba maples around the garden. They seem to be their tree of choice in winter.
