FleecerSpeciesGeographic BoundaryFleecer is a mountain/valley complexbounded by the Fleecer Mountain, Fleecer<strong>Wildlife</strong> Management <strong>Area</strong> (WMA) andInterstate 15 to the east. It covers theMt. Haggin WMA area, north to Anacondaand State Road 1. It crosses Mt. Hagginwest to the Anaconda Range, and thensouth to Anaconda-Pintler Wilderness. <strong>The</strong>southern boundary of the linkage areaincludes the extreme north end of the BigHole Valley near Pintler Creek, and skirtsthe north end of the Dewey linkage area.Importance of Linkage <strong>Area</strong>This linkage provides north-southconnectivity between the Anaconda-Pintlers and the Pioneers, and the FlintCreek Range and the Mount Haggin WMA.It also provides east-west connectivitybetween Fleecer WMA, the Mt. HagginWMA, and the Anaconda-Pintlers. <strong>The</strong>west end connects the Sapphires to theMt. Haggin area across the GeorgetownLake area, with potential for connectingthe <strong>Hub</strong> to the Greater YellowstoneEcosystem and Bitterroots.Mountain Ranges Connected: AnacondaPintlers, Pioneers, Boulders, SapphireEcological Setting<strong>The</strong> Fleecer/Mt. Haggin linkage areaspans the Continental Divide between theBig Hole River and the upper Clark ForkRiver. At an average elevation of 7,000-8,000 feet, this area supports a broaddiversity of forest habitat interspersedwith wet meadow, sagebrush grasslands,aspen stands and complex riparianhabitats. Lodgepole pine (Pinus contorta)and Douglas-fir (Pseudotsuga menziesii)are the dominant conifer species, andsome timber harvest has occurred area-95wide, but most intensively in the Big HoleValley at the west end of the linkage, andaround Mt. Haggin to the northeast. <strong>The</strong>effects of historic copper smelting activityin Anaconda is still reflected in the lackof extensive conifer cover in the northernparts of the linkage. Road developmenthas occurred throughout the linkage butis at relatively low densities. <strong>The</strong> MillCreek-Deep Creek road bisects the linkagebetween Anaconda and the Big Hole River.<strong>The</strong> Pegasus Gold mine was a relativelylarge scale open-pit operation in thenortheast corner of the linkage. Thismine is now shut down and undergoingenvironmental cleanup. <strong>The</strong> north andeast boundaries of the linkage adjoinincreasing industrial and commercialdevelopment. Residential developmentand some subdivision is occurring aroundthe perimeter on the entire linkage,but most prominently on the northeastcorner of the linkage –from Divide throughBuxton and Ramsey to Anaconda – in theInterstate 15 and 90 corridors.<strong>Wildlife</strong>This is high quality habitat for mountaingoats, grizzly bears, wolverine, and biggame.Elk are abundant. <strong>The</strong>y move seasonallyeast-west across the linkage area,summering in the Anaconda-Pintler, movingto the Mt. Haggin area to calve, andwintering in the lower Fleecer area andUpper Rock Creek area. <strong>The</strong> Ralstonfoothills along the lower Big Hole Valleyare another important elk calving area.<strong>The</strong> main migration corridor for seasonalelk movement is between Pintler Creekand the Fleecer WMA. <strong>The</strong> Porters Corner-Georgetown Lake to the east fork of RockCreek is important for elk connectivity;this corridor connects elk between theFlint Creek and Anaconda-Pintler Ranges.
Within the Mt. Haggin WMA, there is a criticalelk winter range in the Fairmont area and NortonCreek area (just west of Ramsey).Moose: <strong>The</strong> Mt. Haggin WMA east of the ContinentalDivide is critical winter range, and providesyear-round habitat. Mill Creek is also veryimportant moose winter range, especially in thelower drainages, as are the Cabbage Gulch, GermanGulch, and Willow Creek areas of the Mt.Haggin WMA. Moose cross I-15 to move betweenthe Fleecer WMA and the Highlands and are alsofound around Georgetown Lake.Pronghorn migrate from winter range nearBannock Dam and the Big Hole River to summerin Mt. Haggin WMA. Additionally, a herd of approximately60 pronghorn live in the Gregsonand Fairmont Hot Springs area and move as faras the Fleecer WMA and Divide area to winter,while another herd stays in the Fleecer WMAyear-round.<strong>The</strong> Lost Creek bighorn sheep herd lives in theAnaconda area. <strong>The</strong> herd appears to be recoveringfrom a prior die-off. It moves betweenthe southern end of the Flint Creek Range, theAnaconda-Pintlers, and west to Rock Creek. <strong>The</strong>West Valley/Lost Creek/Hearst Lake corridor istheir core habitat and winter range. <strong>The</strong> herdmoves across State Road 1 to the Mill Creek areanear West Valley. <strong>The</strong>re is some interchangebetween the Lost Creek herd and the Garrisonbighorn sheep herd.Wolverines exist in the Fleecer linkage, andhave been trapped in Fishtrap Creek, SeymourCreek, and Mill Creek. Wolverine movementcould happen anywhere within the linkage.Due to persistent spring snow, the spine of themountains between Flint Creek and the BeaverheadMountains may be key environment.Grizzly: <strong>The</strong> Fleecer linkage area is very goodgrizzly bear habitat with berry crops and standsof whitebark pine for food sources. Unconfirmedgrizzly bear sightings have occurred inseveral locations throughout this linkage area.A grizzly bear was poached in 2005 in the MillCreek-Joiner Gulch drainage, and was identifiedas a five year old male Northern ContinentalDivide bear by genetic analysis. <strong>The</strong> area betweenGeorgetown and Anaconda is particularly96good [potential] habitat for a variety of wildlife,including grizzly bears, lynx and elk. <strong>The</strong>re aremany black bears in this linkage area.Wolves move throughout the Fleecer linkage.Packs have been surviving within the area longerthan two years due to large numbers of overwintering elk and large areas of protected habitatadjacent to the linkage. <strong>The</strong>re are severalconfirmed breeding packs in this area.<strong>Conservation</strong> ThreatsForest succession and climate change willaffect the quality of habitat for mountaingoats and other species. <strong>The</strong> mountainpine beetle is causing massive mortality oflodgepole pine in this area.Development: <strong>The</strong> Georgetown Lake, WiseRiver ski area, Fleecer area, Fishtrap,West Valley, and Mill Creek/ Highway274 area of this corridor are becomingincreasing developed both residentially andrecreationally, and especially on private landsadjacent to the WMA’s and in the Buxton area.Any land management actions or developmentthat affects ungulate populations are likely toaffect wolverine and wolf populations as well.Due to hunting pressure and otherenvironmental factors, moose populationsappear to be declining in this area.Fencing is an issue for pronghorn between theDivide and Fairmont Hot Springs area.Disease transmission: <strong>The</strong> existence ofmany domestic sheep in the AnacondaValley increases the risk of deadly diseasetransmission to wild sheep herds.<strong>Conservation</strong> OpportunitiesThis linkage area has great portion of landin public ownership, with large contiguousblocks of prime wildlife habitat nearby. Thus,the public commenting process in resourcemanagement plans, forest travel plans,and forest management plans should focuson considerations for wildlife connectivity.Over 10,000 acres of private land are underconsideration for a conservation purchase.Montana Fish, <strong>Wildlife</strong> and Parks have
