Deer Damage Torn Foliage and Twigs vs.
Clean Cut - Deer have no front incisor teeth so
they strip bark by raking their incisors upward, making two-inch gouges.
When they eat foliage, they tear it off, leaving ragged edges and surfaces on
twigs, stems, and leaves. Deer damage will look random and ragged. Rabbits,rodents, and woodchucks, leave a clean-cut edge. If you cut branches off with a knive or saw, this animal damage would look the same.
A rodent will leave a clean cut, usually angled. It looks like someone cut the plants with hand shears and angled the cut.
Deer Damage Clue - Damage Height - Rodents
eat lower parts of trees, up to the height they can reach standing on their hind
legs, which is much lower than deer damage. Deer will also eat plants up the
level they can reach on their hind feet, so the height at which plants are
damaged should eleminate most other suspects.
Deer Tracks - Deer leave deer tracks that distinctive hoof prints. The deer tracks are shaped like broken hearts and are about 2-3 inches long. Running deer leave tracks much farther apart than deer walking or grazing. Be aware however that there are other animals that leave similar tracks. Elk, cattle, llamas, and goats all have similar tracks, but obviously if you don't have any of those other animals in your neighborhood, the suspects are narrowed down considerably.
Deer Scat - Scat, also called deer droppings, is a calling card that you will also find around deer damage. In the winter months when deer are mostly eating twigs and leaves, the droppings will be small elongated pellets. In the spring and summer months when deer are feeding on lush green shoots, leaves, grass, fruit, etc, the pellets clump together and are left as a mass. Droppings that are still shiny are from less than a day ago. Dull droppings may be days old.
Rabbit droppings may be mistaken for deer droppings, but are smaller andperfectly round. Goat and sheep droppings are more elongated. Skunks, raccoons, and opossums leave droppings like a dog.
Time of Day - Deer are most active just after dusk and just before dawn. If your damage is being done in the daytime, look around your area for daytime feeders like goats or sheep. Sometimes even dogs will eat some plants. You might want to invest in a wildlife camera for less than $100 and get some pictures of what is going on around your property on a 24 hour basis.
What You See Is What You
Get - You see deer in your yard and/or have to slow down regularly in
your car so that you don't hit a deer. If you
are seeing them, the poplulation is high enough to threaten your plants. The
best time to see deer are around dusk and dark.
