We investigated habitat use of Columbian black-tailed deer in urban Vancouver, Clark County, Washington, at 3 spatial scales: (1) placement of the annual home range within the landscape mosaic, (2) annual and seasonal locations of deer within the annual home range, and (3) short-term use of critical habitats (fawning areas) within seasonal by: Survival of Columbian White-Tailed Deer in Western Oregon Article in Journal of Wildlife Management 66(4) October with 9 Reads How we measure 'reads'.
Two forms of black-tailed deer or blacktail deer that occupy coastal woodlands in the Pacific Northwest of North America are subspecies of the mule deer (Odocoileus hemionus).They have sometimes been treated as a species, but virtually all recent authorities maintain they are subspecies. The Columbian black-tailed deer (O. h. columbianus) is found in western North Class: Mammalia. North Bank Habitat near Roseburg a haven for Columbia white-tailed deer Febru Oregon, Statesman Journal Columbia white-tailed deer once roamed most of Western Oregon. But as pioneers began farming the deer’s favored valley habitat the whitetails gradually lost ground to their larger, black-tailed cousins from the uplands.
There is a small population of Columbian white-tailed deer in Douglas County and the Columbia River Gorge, some of which were moved during when it was feared they would be flooded. These deer were common in Western Oregon, but fewer than remained in Farming altered their major habitat. Columbian White Tailed Deer Hunting: Our Columbia whitetail hunts are offered on 7, acres of private land in Douglas County, OR and we receive five coveted tags annually for our leased properties. We run our hunts as an all inclusive 1x1 four day guided hunt including logging and meals and have run % opportunity and 98% success over the past six seasons.

A study conducted May December determined that the present geographic range of Columbian white-tailed deer, Odocoileus virginianus leucurus, (CWTD) in Douglas County, Oregon encompassed km2. The area was predominately a Quercus woodland community, typical of the Interior Valley Zone of western by: Columbian white-tailed deer are closely associated with riparian (riverside) habitats in both the Lower Columbia River and Douglas County populations.
The deer found on islands in the Columbia River use "tidal spruce" habitats characterized by densely forested swamps covered with tall shrubs and scattered spruce, alder, cottonwood and willows.

Habitat and description. The Columbian white-tailed deer is named after the Columbia River in Oregon and Washington where it congregates.
Columbian white-tailed deer are found along the lower Columbia River, on a series of islands in Clatsop and Columbia counties in Oregon, and Wahkiakum County, Washington.
Other populations are found in the valley floors of the Family: Cervidae. Therefore, on J that the Douglas County, Oregon population of the Columbian white-tailed deer was removed from the federal Oregon book of threatened and endangered species. The final rule to delist the Columbian white-tailed deer was published in the Federal Register on J Two distinct populations of Columbian white-tailed deer are known: the Columbian River population on both banks of the river in Clatsop County, Oregon, and Wahkiakum County, Washington; and the Roseburg population in Douglas County near the town of Roseburg.
The Roseburg population is larger, numbering between 2, and 2, animals. In the s, the Douglas County Columbian white-tailed deer population was estimated at to individuals occupying a range of only about 31 square miles .
Bythe population had increased to about 2, deer . The population has continued to grow and is currently estimated at over 6, deer . Oregon offers diverse deer hunting opportunities among beautiful landscapes, with both over-the-counter general tags and controlled tags available.
Western Oregon’s reclusive black-tails live in the lush habitat of the coastal mountains and western Cascades. Eastern Oregon’s mule deer live in the more open country of the High Desert and the northeast. Columbian white-tailed deer were listed as a federally endangered species inand listed by Oregon in The Columbia River population is still listed under the federal Endangered Species Act (ESA).
However, the Roseburg population has been de-listed, and in a hunting season was opened for this population for the first time in almost 40 years. COLUMBIAN WHITE-TAILED DEER T he acquisition of Columbian white-tailed deer habitat by public agencies has helped provide protected habitat for the two distinct populations of the deer.
In Douglas County, Oregon, the animal is thriving, and the U.S. Fish and Wildlife Service in removed that population from the federal endangered species list. Columbian White-tailed Deer currently occupy two isolated populations, the larger of which occurs in Douglas County, Oregon.
The other occurs along the shores of the lower Columbia River with a range extending from Ridgefield National Wildlife Refuge (NWR) downstream to. Columbian white-tailed and black-tailed deer exhibited strong seasonal similarities in diets with overlap ranging from 89 to 95%. White-tailed deer diets were dominated by forbs, shrubs, grasses, and other food sources (e.g., nuts, lichens).
Columbian black-tailed deer diets were dominated mostly by forbs and other food by: 2. The Columbian white-tailed deer was listed in due to habitat loss and modification by human activities, such as farming and logging, as well as commercial and residential development.
Habitat. The Columbian black tailed deer (Odocoileus hemiounus columbianus) can be found in the western coast of the North America, anywhere from northwestern California all the way up to southwestern Alaska (Kucera and Mayer ).The habitat mainly consists of blossoms, deer brush, oaks and some open areas with perennial grass (Kucera and Mayer ).

This rare sub-species of Whitetail Deer was on the endangered species list since In they were delisted and a handful of tags were made available to the public. Douglas County's Columbian White-tailed Deer Habitat Protection Program was established in (DCPD a).
The County, in conjunction with the ODFW and us, identified the range of habitat with the greatest density of Columbian white-tailed deer, ha (73, ac) were designated as Essential Habitat Areas (DCPD ).
Columbian white-tailed deer have settled into the Ridgefield National Wildlife Refuge since when the U.S. Fish and Wildlife Service relocated 88 deer to the protected habitat. It was among the first group of animals protected under the Act in Habitat protections and acquisitions followed, and deer were introduced to new islands, increasing its range and security.
As a result the Columbian white-tailed deer increased from individuals in to in Species profile about species listing status, federal register publications, recovery, critical habitat, conservation planning, petitions, and life history U.S. Fish & Wildlife Service ECOS Environmental Conservation Online System.
