Black-tailed deer are a subspecies of mule deer found in the coastal regions of northwestern North America from California to Alaska. Black-tailed deer are categorized by two common mule deer subspecies: Columbian black-tailed deer Odocoileus hemionus columbianus and Sitka black-tailed deer Odocoileus hemionus sitkensis 3. Columbian blacktails can be found in the coastal areas of northern California, Oregon, Washington, and southern British Columbia, whereas the Sitka subspecies are found on coastal areas of northern British Columbia and southeastern Alaska.

Black-tailed deer are differentiated by their body and antler size, color, geographical distribution, habitat preference, and even their DNA.

Aptly named, the tail of black-tailed deer is black from tip to rump. In many parts of their distribution, mule deer overlap with a closely related species, the white-tailed deer Odocoileus virginianus. Sometimes mule deer and white-tailed deer will hybridize, but this is a rare phenomenon.

Understanding their differences is important for proper identification. Although similar in many respects, mule deer and white-tailed deer are distinguishable in their behavior, biology, and appearance.

For example, the most commonly noted difference between the two species is their antler configuration 1. Mule deer usually have small or missing brow tines with bifurcated antler branching, which means tines that split once off of a main beam, and then again toward the tips. White-tailed deer antlers usually have prominent brow tines, and tines that split once directly off the main beam.

Another distinguishable characteristic between mule deer and whitetails is the appearance and color of their rump. Mule deer have a rope-like tail with a distinctive black tip, while whitetails have a more flat, triangular-shaped tail that is brown on the back surface, and a pure white bottom. The breeding season rut generally occurs in November or December, but can vary based on location. For example in the Southwest Desert, the rut may occur as late as January-February. Bucks spar during the rut, competing for receptive does.

Older bucks with large antlers usually outcompete younger bucks with smaller antlers for mates, but that is not always the case 4. After being bred, does begin a 7 month gestation period and fawns are dropped in late spring and summer: coinciding with an abundance of nutritious food for lactation 1.

Females give birth to usually one or two fawns, with twins being more common among does in prime breeding age whose nutritional needs are met. Fawn to doe ratios are often used by wildlife managers as an important marker for mule deer population health. Fawns may weigh between pounds, and heavier fawn weights are usually indicative of good maternal nutritional status and a higher probability of fawn survival 5.

Mule deer are herbivores with a four chambered stomach similar to cattle, elk, and other ruminants. They digest food by regurgitating partially digested plants, re-chewing, and resting to allow for bacterial breakdown of plant material 1. Mule deer are not as efficient at digesting fibrous material as cattle and elk, so they feed on plants that provide concentrated and highly digestible nutrients. In order to take advantage of the most nutritious plants throughout the year, mule deer may change their diets seasonally.

During the winter when herbaceous plants die off, mule deer switch to the nutritious buds and leaves of woody vegetation browse such as sagebrush, bitterbrush, mountain mahogany, and cliffrose. In the winter when food resources become scarce, mule deer may burn more calories in a day than what they can consume. During this period, loss of body mass can be substantial 5. Across their distribution, mule deer habitat is broadly categorized in seven ecoregions where mule deer populations share similarities in their ecological associations 1 , those ecoregions are: Intermountain West, Great Plains, Northern Forest, Colorado Plateau Shrubland and Forest, Coastal Rainforest, California Woodland Chaparral, and Southwest Desert.

Within each ecoregion, there are a wide variety of habitat types mule deer associate to. For example, mule deer of the western Great Plains region have a greater component of open grassland habitat than black-tailed deer in the Coastal Rainforest region.

In general, areas with occasional disturbance and edge stimulates growth of grasses, forbs, and shrubs that are within reach of the deer. Consequently, wildfire, grazing, and forest management practices can have an enormous impact on habitat quality.

Migration is the seasonal movement between habitats. For mule deer this is typically the biannual movements between high elevation summer range and lower elevation winter range.

Not every mule deer is migratory, as some remain on their range year-round 7. Migration is typically prompted by changes in food availability and weather 8. Migration routes can be well over miles in length, and function not only as travel corridors, but also as important foraging habitats 9. The longest documented mule deer migration is over miles from winter range in the Red Desert of Wyoming to summer range near Island Park, Idaho.

It is believed that mule deer learn migration routes from their mothers, and typically follow that same route for the rest of their lives Mule deer populations have a history of fluctuating through time 1. The factors adversely affecting mule deer populations today include habitat loss and fragmentation, poor forage quality, drought, severe weather, competition with other ungulates, predation, disease, and poaching 2. Among ecoregions there are diverse environmental and climatic conditions, therefore each ecoregion presents different challenges to mule deer populations 1.

For example, in the Southwest Desert ecoregion, drought is a serious concern and water availability is a key factor affecting mule deer populations. Deer have excellent sight and smell. Their large ears can move independently of each other and pick up any unusual sounds that may signal danger. At dawn, dusk, and moonlit nights, deer are seen browsing on the roadside.

Wooded areas with forests on both sides of the road and open, grassy areas, i. Caution when driving is prudent because often as one deer crosses, another one or two follow. In Southeast Alaska, the Sitka deer is the primary prey of the rare Alexander Archipelago wolf Canis lupus ligoni , which is endemic to the region.

The protections for the wolf included a standard and guideline intended to retain, in the face of logging losses, enough habitat carrying capacity for deer in winter to assure the viability of the Alexander Archipelago wolf and an adequate supply of deer for hunters. The needed carrying capacity was originally specified as 13 deer per square mile, but was corrected in to Use of a deer model is specified for determining carrying capacity, and is the only tool available for the purpose.

However, the Forest Service’s implementation of the deer provision in the Tongass wolf standard and guideline has been controversial for many years, and led to a lawsuit by Greenpeace and Cascadia Wildlands in , over four logging projects.

The data set the Forest Service was using in the deer model was known through the agency’s own study done in to generally overestimate the carrying capacity for deer and underestimate the impacts of logging. Regarding the Traitors Cove Timber Sales project, in the plaintiffs noted in oral arguments before the 9th Circuit Court of Appeals that the difference is between a claimed 21 deer per square mile carrying capacity in the project EIS, and 9.

The 9th Circuit panel ruled unanimously on August 2, , in favor of the plaintiffs, remanding the four timber sale decisions to the Forest Service and giving guidance for what is necessary during reanalysis of impacts to deer. We do not think that USFS has adequately explained its decision to approve the four logging projects in the Tongass. USFS has failed to explain how it ended up with a table that identifies deer per square mile as a maximum carrying capacity, but allows deer per square mile as a potential carrying capacity.

Coast Fed’n of Fisherman’s Ass’ns v. Bureau of Reclamation, F. We have similar questions about USFS’s use of VolStrata data, which identifies total timber volume and not forest structure, to approve the projects, where forest structure—and not total timber volume—is relevant to the habitability of a piece of land. Because we must remand to the agency to re-examine its Deer Model, we need not decide whether the use of the VolStrata data was arbitrary and capricious. We anticipate that, in reviewing the proposed projects, USFS will use the best available data In a statement to the press, a spokesman for the plaintiffs said the errors in this lawsuit apply to every significant Tongass timber sale decision between and , before the Forest Service corrected errors in the deer model when the agency issued its revised Tongass Forest Plan in But he said despite those corrections, the agency still fails to address cumulative impacts to deer, especially on Prince of Wales Island, as is being challenged in the Logjam timber sale lawsuit, by ignoring substantial logging on nonfederal lands.

District Court in Anchorage made a second remand to the Forest Service because the agency’s further work under the first remand had not resolved the modeling issues. Activity on the four timber sales involved in the litigation has been suspended since From Wikipedia, the free encyclopedia.

Scientists have estimated that, before the arrival of Europeans, North America supported some 40 million whitetail and 10 million mule deer. However, through the last-minute implementation of laws limiting the annual deer kill, ars encroaching extinction was checked. During the past half century, as a result of the establishment of wildlife control programs that favor game species, our deer population has increased to the point where—according to the latest estimates of the Wildlife Management Institute of Washington, D.

Whitetail deer are most abundant in the eastern U. Its length nose to tip of tail runs from 60 to 75 inches or so, with live weight averaging around pounds. The largest whitetail buck on record pegged the defr at pounds.

Though the tail of O. When the tail приведенная ссылка held tightly against the blacktaail, little if any white is visible, and the animal remains well camouflaged. The antlers of the whitetail have all of their tines, or points, sprouting from the two main beams.

The coastal blacktail deer is surrounded by confusion—most детальнее на этой странице which arises from the longstanding practice of using the terms blacktail and mule deer interchangeably.

Technically, the only deer that can properly be called a blacktail is the Pacific coastal blacktailwhich, as its name indicates, occupies a thin strip of coastal forest and a few offshore islands extending from Alaska south into the northern half of California. Adults stand 36 to 38 inches at the shoulders, measure 60 inches or so nose to tail, carolin weigh about pounds-though recordbook blacktail bucks are there blacktail deer in north carolina near pounds are not unknown.

Another characteristic the coastal blacktail and the mule deer share—and a way in which they both differ noticeably from the white-tail is style of locomotion. While the whitetail runs by pushing off alternately with its front and rear legs in long, graceful bounds, blacktails and mule deer typically launch themselves with all four legs at once in bouncing, pogo-stick jumps that verge on the comical— boing, boing —each bound gaining as much altitude as forward distance.

But differences in species aside, deer are deer. All have keen senses of smell, hearing, and vision in that order. All are there blacktail deer in north carolina to browse when they can, are there blacktail deer in north carolina graze when they must, consuming soft vegetation in summer, while relying primarily on brush in winter. All are blackttail that they have multi-compartmented stomachs and chew cud.

And all breed in fall and early winter, giving birth to their young from late spring through early der. Although the terms are often used interchangeably, there are several significant differences between antler and horn.

The most apparent, of course, is inform: Horns are composed of single beams though they often curl and twist into odd shapeswhereas antlers are branched and multitined, often taking on bizarre and complex patterns.

Some species such as moose and caribou have antlers that are palmate: broad and flat, resembling massive hands with the fingers spread. The single, striking exception to this rule is the pronghorn antelope—Antilocapra americana—which sheds the outer sheath of its horns annually, but retains a living, bony matrix around which a new sheath forms.

And, finally, antlers grow from their tips and are composed of solid bone. Antler growth is timed to coincide with the annual mating season. Starting in early spring and continuing through midsummer, the new antlers develop.

By late summer, with mating season just around the corner, best to stay in carolina mountains velvet begins to die, dry, and peel away from the hardening antlers—a process the buck speeds along by rubbing are there blacktail deer in north carolina rack against flexible saplings, then honing the oklahoma football to rapierlike sharpness on soft-barked trees.
