evidence: Deer, rabbits, squirrels, woodchucks and birds, especially crows, can cause troublesome damage in the vegetable garden. In some areas, chipmunks, porcupines and voles develop a taste for vegetables. Raccoons notoriously appear just as the corn is ripening. [...] Though porcupines are more likely to injure fruit trees and berries, they sometimes develop a taste for certain succulent vegetables. Their droppings measure about ½" – 1 1/8" long and are sometimes slightly "C" shaped and strung together. These rodents have a strong attraction to salt from sweat left on tool handles and gloves. Fencing as for woodchucks is usually effective. Porcupines climb, but they don’t burrow.
