The presence of mountain goats in Oregon prior to Euro- pean settlement is supported by archeological evidence in Hells Canyon and Wildcat Canyon, 30 miles east of The Dalles. Rocky Mountain goats were apparently extirpated from Oregon prior to, or soon after, European settlement. Life History Goats Mountain goat pelage is comprised of white wool and white guard hairs. Their hooves have cushion-like pads surrounded by a hard shell, allowing a grip on smooth rock Rocky Mountain surfaces. During summer months females molt about a month later than males, which is useful in determining sex of adults. Animals will often rub against obstacles, leaving clumps of discarded wool on shrubs and trees. Age can be determined by counting horn rings as with bighorn sheep. The first ring is formed during the second winter at 22 months of age. Black glands behind the horns are used for marking territory during the rut by rubbing brush. Females can normally Oregon Department breed at 2 ½ years of age, usually producing a single kid, although twins are not un- of Fish and Wildlife common. Breeding takes place from early November to mid-December. Kids are born 3406 Cherry Ave NE approximately 7 months later during late May or early June. Salem, OR 97303 www.dfw.state.or.us Cougar and golden eagles are the most significant predators of mountain goats. Gold- en eagles take newborn kids and sometimes knock young sheep from cliffs. Accidental death is also a significant mortality factor. Diet varies among populations according to the geographical location and plant avail- ability. Grasses, shrubs, and mosses or lichens are consumed. Salt licks are used exten- sively during the summer. Distribution The Elkhorn Mountains herd is found from Anthony Lakes on the northwest end to Marble Creek, going southeast. Mountain goats from the Elkhorn herd have dispersed to locations to the west such as Indian Rock, Vinegar Hill, Dixie Mountain, Cable Creek, and the Strawberry Mountains.

The information in this report may not be published or used for other purposes without permission of MFWP. Montana Fish, Wildlife & Parks Region One Headquarters 490 Meridian Road Prepared by Jessy Coltrane, PhD Kalispell, Montana 59901 Kalispell Area Wildlife Biologist INTRODUCTION Mountain goats (Oreamos americanus) historically occupied most available montane cliff habitat throughout northwest Montana (Fish Wildlife & Parks, Administrative Region 1); however, since the 1950s, native mountain goat numbers have experienced a dramatic decline. Thus, once occupied habitat is now devoid of goats, and current mountain goat range is significantly reduced from its historic expanse. In the 1940s and 1950s, mountain goats were considered an abundant and not easily depleted resource in northwest Montana. Population estimates for mountain goats in the region described 350 mountain goats in the Swan Mountains, 20 in the North Fork of the Flathead, 315 in the Clark’s Fork, 900 in Glacier Park, 100 near Coram, 450 from Spotted Bear to Schaffer Meadows, and 250 in Big Prairie (Montana Department of Fish and Game 1958). Native herds in the South Fork of the Flathead River and the Swan Mountains were used as source populations to establish new goat herds in mountain ranges throughout Montana and Colorado. From 1948 to 1953, 66 goats were transplanted from the South Fork of the Flathead River and 13 from Van Lookout in the Swan Range (Picton and Lonner 2008). In addition to capture removals, wildlife managers allowed for unlimited harvest of mountain goats.

  • A Brief History of Mountain Goat Population Management on the Kenai Peninsula by Dom Watts
    Refuge Notebook • Vol. 19, No. 12 • March 24, 2017 A brief history of mountain goat population management on the Kenai Peninsula by Dom Watts Prior to 1971, mountain goat harvests in the Kenai Mountains were essentially unrestricted. Harvests during the 1950s and 1960s resulted in significant de- clines in many mountain goat populations. As rela- tively high harvests continued throughout the 1970s, Kenai goat populations declined by 25% or more. Much of the following was pulled from an excellent article by Thomas McDonough and Jeff Selinger, local biologists with the Alaska Department of Fish & Game. In some areas, like Cecil Rhode Mountain near Cooper Landing, overharvests even resulted in lo- calized extirpation. Reintroductions during the early 1980s, coupled with natural recolonization from nearby areas and limited local harvests, helped Mountain goat populations may be increasing on the reestablish the population of mountain goats that we Kenai Peninsula (credit: National Park Service). see there today.

Acta Vet Scand (2018) 60:12 https://doi.org/10.1186/s13028-018-0366-8 Acta Veterinaria Scandinavica RESEARCH Open Access Orf virus infection in Alaskan mountain goats, Dall’s sheep, muskoxen, caribou and Sitka black‑tailed deer Morten Tryland1* , Kimberlee Beth Beckmen2, Kathleen Ann Burek‑Huntington3, Eva Marie Breines1 and Joern Klein4* Abstract Background: The zoonotic Orf virus (ORFV; genus Parapoxvirus, Poxviridae family) occurs worldwide and is transmit‑ ted between sheep and goats, wildlife and man. Archived tissue samples from 16 Alaskan wildlife cases, representing mountain goat (Oreamnos americanus, n 8), Dall’s sheep (Ovis dalli dalli, n 3), muskox (Ovibos moschatus, n 3), Sitka black-tailed deer (Odocoileus hemionus= sitkensis, n 1) and caribou (Rangifer= tarandus granti, n 1), were analyzed.= = = Results: Clinical signs and pathology were most severe in mountain goats, afecting most mucocutaneous regions, including palpebrae, nares, lips, anus, prepuce or vulva, as well as coronary bands. The proliferative masses were solid and nodular, covered by dark friable crusts. For Dall’s sheep lambs and juveniles, the gross lesions were similar to those of mountain goats, but not as extensive. The muskoxen displayed ulcerative lesions on the legs. The caribou had two ulcerative lesions on the upper lip, as well as lesions on the distal part of the legs, around the main and dew claws. A large hairless spherical mass, with the characteristics of a fbroma, was sampled from a Sitka black-tailed deer, which did not show proliferative lesions typical of an ORFV infection. Polymerase chain reaction analyses for B2L, GIF, vIL-10 and ATI demonstrated ORFV specifc DNA in all cases.

  • Mountain Goat Resource Brief
    Crown of the Continent National Park Service U.S. Department of the Interior Research Learning Center Glacier National Park Mountain Goats (Oreamnos americanus) Resource Brief Background Information One of Glacier National Park’s iconic species, the moun- tain goat is only found in the northern latitudes of North America, and is more closely related to serows and cham- ois from Eurasia than to domestic goats. Some mountain goat populations now found in the U.S. were introduced, but Glacier’s goats are native to the landscape. Mountain goats primarily inhabit alpine and subalpine environ- ments and are often found traversing nearly vertical cliffs. They are exceptional climbers, using their large, muscular forequarters to climb steep slopes of 60 degrees or more. Mountain goats have cloven hooves, or a hoof split into two toes, which spread out when needed. This stability, along with flexible, soft inner pads, allows the goats to grip the rocky ledges and cliffs they inhabit. Summer months provide abundant food for mountain goats including a variety of alpine flowers, grasses, and sedges. During the long winter months, the mountain goat’s diet is more sparse. They winter high on steep cliffs Photo by Chris Peterson where snow sheds readily or in areas where little snow accumulates. Here they find exposed vegetation not eaten Exceptional climbers, mountain goats are often seen on rocky, steep cliffs. However, goats also use dense timber and creek bottoms for security and during the summer as well as shrubs and lichens. Although protection against extreme heat, cold, and wind. treacherous, these steep cliffs not only provide food for the goats, but also offer protection from predators.
