If you are careful, you can remove it from the mount with very little damage. Its time consuming, but you can use an exacto knife to remove the roots from the mount. Just slide the blade under each individual root starting from the tip, using a very small angle- about 5 degrees (.1 radians). You should try to shave some of the mount wood off as you go, although this wont happen that much. Its really just prying the roots off. Make sure to soak the mount first.
