                                                          Unlike rabbit droppings which are very dry and quite perfectly round, a deer dropping is

Beds: Deer lay directly on the ground to rest. These
beds are oval in shape, about 3 to 4 feet long and 18
inches wide. In summer, look for matted grasses in
old fields and pastures or flattened leaves under trees
or shrubs. In winter, watch for melted or dented areas
in the snow. Deer often bed together so you will
frequently find two or more beds in a bedding area.

use their hooves, antlers, and teeth as a last resort. White-tailed deer also have a very high
reproductive rate that is typical of animals near the bottom of the food chain. Under natural
circumstances, this high birth rate is necessary to maintain their numbers in the face of
constant loss to predation and variation in food supply.

The large eyes of a deer are situated on the side of its head. This allows the animal to see not
only straight ahead, but also to its side and behind it without moving its head. Their night
vision is excellent and their daytime vision is very good, especially for detecting movement. A
deer's oversized ears help it hear very well. It can rotate its cupped ears like a radar dish to
help it pick up even the faintest sounds made in the nearby woods and fields. Their ears are
spaced widely apart on their head to enable them to use triangulation to pinpoint sounds.

colonies of microorganisms that ferment the food by producing cellulase capable of slowly
breaking down the fibrous plant material. This fermentation produces heat. So, in hot
weather, deer seek cool, shady spots to chew their cud. In winter, the rumen acts like a
furnace. Except in extreme cold, this internal furnace allows deer to stay bedded without
having to get up and move around.

If a deer, especially a fawn, is injured, trapped or otherwise terrified, it will make a high pitched
sound in a manner similar to how a cow calf bawls for its mother. If it is chased by a predator,
the usually quiet fawn will make "bleating" sounds as it runs away. This will alert the doe who

spend a lot of time in deep forest and thickets. Therefore, they rely heavily on chemical scent
to communicate with each other, since scent travels farther and lasts longer than either visual
or vocal communications. Deer have a variety of glands on their toes, legs, near their eyes and
on their heads. They leave scents when they walk, urinate, rub on trees or make scrapes on
the ground.

Deer pose a serious threat to Wisconsin's natural areas, hampering wildland conservation
efforts as effectively as do invasive species and loss of habitat. Foraging deer determine how
tall palatable plants will grow, whether the plants will bloom or not and, in some cases,
whether the plants will exist at all. Due to their nature, deer browse and graze intermittently,
one plant here and another there, returning the next day for more, especially in areas that
protect deer in refuges during the deer hunting season. Tour one of these refuges and you’ll
find obvious browse lines where deer have munched the leaves as high as they can reach.
Eventually, some of these plants die, as pieces are lopped off bit by bit, year after year.

The low layer of vegetation below the browse line is the woodlands' understory. This
important layer of the forest provides habitat needed by smaller brush-dwelling animals such as
salamanders, frogs, toads, shrews, deer mice, rabbits, squirrels, opossums, skunks, raccoons,
and a variety of understory nesting birds from ruffed grouse to wood thrushes and ovenbirds.

of the 20th Century in the form of restrictions upon the hunter. The first bag limit was
established in 1897. Hunters were required to accompany any deer carcass that was
transported. Possession of fawn skins or skins in the red (summer color) was made illegal.
Hotels and restaurants could serve venison only during the hunting season. It became lawful
to shoot dogs chasing deer. Various counties closed deer hunting. Statewide, annual seasons
began to open in November rather than in October and a shorter season was adopted. For the
first time, hunting licenses were required by both resident and non-resident hunters. The
federal government got involved, too, and enacted the Lacey Act which made it illegal to ship
game killed in violation of local law.

Unfortunately, hunters’ disregard of the new game laws was rampant so over-shooting

were licensed in 1910. This jumped to 115,000 in 1916. Wisconsin's Biennial Report of
1917-18 stated: "Deer, as well as other wild game, have a new weapon pointed at them, more
deadly than powder and bullets and much harder to escape, as the range is long and it reaches
out into the remote districts where deer once found refuge safe from the pursuit of the
hunter. The automobile has annihilated this space, and distance will no longer protect them."
White-tailed Deer Management
White-tailed deer are the most intensively managed animal in Wisconsin DNR’s Wildlife
Management Program. That's because deer are valued by many people--from hunters to
wildlife photographers.
Deer have become virtual
icons in many people's
minds as one of the last
vestiges of unsettled
America. But these
elegant creatures have also
sparked contentious
public policy debates over
just how Wisconsin's deer
herd should be managed.
Deer populations can be
maintained indefinitely
where suitable habitat
exists. Economically, deer
and deer hunting generate
a huge flow of income.
20 million dollars are collected in license fees alone. And hunters bring a big influx of dollars
into rural communities in Wisconsin's great northwoods.
