I had never heard of a "vole" before becoming a member of DG, and then I still thought folks were accidentally misspelling "mole." This article explains a LOT!! We have a massive number of moles trying hard to change the landscape of our neighborhood, but I was always told that moles did not eat the plants, although a few might become collateral damage.
Last year I was photographing my two precious stevia plants and one literally fell over for no apparent reason. Upon inspection, it had been cut, or bitten in two, just below the ground level. I could see the dirt moving beside the plant as the critter tunneled underneath. I won't bother telling you what happened next... I was very angry... neighbors pointed... cars stopped! At that point I assumed it was a mole and all the stories I had heard were false. Because of this article, I know now it was a VOLE! I now have two separate pests to battle, but feel much better prepared!
Thank you so much for the enlightenment!!!
PS: Wikipedia had this vole pic, and said they were monogamous creatures... aaaah! I still don't like them!
AHA! Now I can tell my dear, distraught gardening friend Anita that it really isn't "the mole" (as she tells it) de-rooting her plants, that it IS "the vole". Will try to persuade her to use traps, since her cat is old and lazy . . .
