I <br /> APPEiVDIX C3 <br /> Alternative Descr otion <br /> (Alternative C) <br /> Selected <br /> aea■� <br /> The following management zones and :management units are visually disolayea to provide a <br /> comparison to the Present Situation: <br /> Acres <br /> Crest Zone 21900 • <br /> Intermediate Zone (Area not in Management Units) 35,500 <br /> I-1 Perham Creek Management Unit 12,200 <br /> I-2 Coal Basin Management Unit 9,100 <br /> I-3 Middle Thompson-So. Branch Management Unit 16,000 <br /> Travel Influence Zone (Area not in Management Units) 9,850 <br /> T-1 Sunlight inventoried ski area Management Unit 3,450 <br /> T-2 Coal Basin Management Unit 4,450 <br /> Water Influence Zone 3�3,600 <br /> This alternative emphasizes maximum development of wood products, foraae, water and wild- <br /> life. The protection of summer big-game habitat was the critical element in developing this <br /> alternative. As a result the Middle Thompson-So. Branch Manaaement Unit (I-3) was estab- <br /> lished to adequately protect these wildlife considerations. Perham Creek Management Unit <br /> (I-1), Coal Basin Management Unit (I-2), and Coal Basin Management Unit (T-2) would not <br /> change from Alternative A. <br /> The Perham Creek Roadless Area (I-1) was evaluated under all alternatives. The significant <br /> factors influencing management direction are as follows: <br /> -The narrow-type shape, containing a relatively small area of 16,000 acres is not con- <br /> ducive to managing the area for the wilderness values. <br /> -There are ten 'Wilderness and Primitive Areas consisting of 1 ,C61 ,407 acres within 150 <br /> ml es radius to meet ouolic demands for wilderness ocoor,,un ti es. ;n addition, the <br /> Maroon Bells-Snowmass and Chair Mountain New Stud reas contain 95,965 acres. <br /> -ihe Pernam Creek Road less Area as defined in 1971 aid contain, and still does include <br /> man-made roads providing access to adjoining private lands. This was the basic reason <br /> for adjusting acreage to meet suitability criteria. <br /> -Opportunities for solitude are limited due to size, shape and proximity to State <br /> Highway 133. <br /> -Scenic ^utilities and var4etv of landscape are not significant enough to warrant <br /> wilderness ce5ignation. <br /> Using this information, the management emphasis of this alternative and the innerent <br /> characteristics of the Perham Creek area for backceuntry experience would compliment each <br /> other in a satisfactory manner. <br /> Considering the issues to be resolved, the coals and objectives developed and the capa- <br /> bilities of the land to produce certain commodities, this alternative best meets the <br /> desired management direction. <br /> Goner&] Emonasis: Maximum development of livestock forage, -ocd ;roducts, water ,yield and wildlife <br /> values, with increasing emonasis on controlling vehicular access. <br /> Effects: -Protect and enhance wildlife haoitat by controlling access into Middle 4 <br /> Thompson and South Branch Creeks. ! <br /> -Permits intensive t,mcer management practices to maintain a healthy forest, <br /> contributing to esthetic, recreation, wildlife and watershea values. <br /> Ke option °or expansion of the exisrs Sunl r_ht ski area to 3000 PACT <br /> AM nrnf ar•c ',•� a�� tc <br /> r.n oven. r'eC SC' 3^eII Or Ul oomint 0 <br /> 3000 2ACT. <br /> -�mmunity growth would not be stimulated at a rate which could be a burcen to <br /> local government. <br /> -provides for 1Z,2200 acres of Pernam Creek roadless area. <br /> -increase Annual 'dater Yield. <br /> -Provides for continued energy oevelooment. <br /> -Use of the transportation system beyond the Themoson Creek Ditch by vehicles <br /> for general enjoyment and s,gntsee,ng will not be oermitted. <br /> -Nineteen miles of additional roadway would oe necassary, taking 104 acres of <br /> National ;crest out of production. <br /> -increased recreation adjacent to State Highway 133 could affect the natural <br /> environment. <br /> -:later duality may be temocrar!ly reduced. <br /> --In Coal Basin and Sunlight, forvo deveiooments other than those comoatible wit.'A <br /> winter spores. <br /> -The•natirRa-ppearing landscape will be altered. <br /> �jl�►•r�f�IJaS 20�1/ <br />
