Payette National Forest (Idaho) 



The Payette Forest (1,202,451 acres) 

 lies upon an extensive granite uplift 

 in central Idaho. There is no general 

 structural trend to the ridges which 

 are products of erosion. The canyons 

 are steep sided and frequently very rock} 1 -. 

 Much of the Forest lies in a country 

 difficult of access and is practically 

 virgin in every respect. There are 

 practically no areas closed to stock or 

 inaccessible to them, although grazing 

 is very light on the Middle Fork of the 

 Salmon River and will probably be 

 entirely stopped within a few years, 

 the State having established a game 

 preserve there. Timber cutting is light. 

 The major types in order of abundance 

 are: western yellow pine 29%, Douglas 

 fir 20%, subalpine 20%, lodgepole pine 

 16%, brush 8%, grass 6%. 



Permanent sample plots in the yellow 

 pine type have been established by the 

 Forest Service on this Forest. These 

 plots are grazed, and are to be cut over 

 under different methods (check plots 

 reserved). Abies grandis and Larix 

 occidentdlis find their southern limits 

 on this Forest. 



There are extensive game areas within 

 the Payette Forest where deer, bighorn 

 sheep and mountain goats are abundant. 

 There is a great variety of fish and con- 

 siderable numbers of migratory species 

 spawn within the boundaries of the 

 Forest. In some of the inaccessible 

 regions practically virgin conditions 

 are found in the streams. The introduc- 

 tion of various fish species will, within 

 a few years bring about an adjustment 

 .of the native species.

Powell National Forest (Utah) 



The Powell Forest (about 1,046,000 

 acres) lies upon the Aquarius, Sevier 

 and Paunsagunt Plateaus, which bear 

 on their tops, stands of spruce, fir, 



and pine, breaking off into pine and 

 juniper slopes. Grazing is heavy and 

 general, except where the topography is 

 locally precipitous. Little logging has 

 been done in the yellow pine type. 

 Forest conditions are essentially virgin. 

 The major types (Powell Division only) 

 run: western yellow pine 28%, Engel- 

 mann spruce 27%, pinyon-juniper 27%, 

 aspen 8%, grass 7%.

Salmon National Forest (Idaho) 



The Salmon Forest (1,620,265 acres) 

 lies in central Idaho upon several moun- 

 tain ranges. It is generally rough and 

 in the higher and more remote sections 

 natural conditions are generally found. 

 There are no completely protected areas 

 on the Forest. Grazing is general, but 

 a large area on the Middle Fork of the 

 Salmon River and the northwest corner 

 of the Forest is too rocky and steep to 

 be accessible to domestic stock, while 

 an area near Salmon City is protected on 

 account of the municipal watershed and 

 a small area in the north end (Ditch 

 Creek) is preserved from grazing as a 

 huckleberry patch. A State Game Pre- 

 serve occupies a part of the area inac- 

 cessible to domestic stock and about two 

 townships of the accessible area ad- 

 joining. Cut-over areas are small. The 

 major types are: lodgepole pine 37%, 

 Douglas fir 31%, western yellow pine 

 10%, sage 6%, subalpine 6%. The 

 southeastern limits of western yellow 

 pine in Idaho are found on this Forest.

Sawtooth National Forest (Idaho) 



The Sawtooth Forest (1,159,339 acres) 

 consists of a broken mountainous coun- 

 try characterized by main ridges of 

 great height and ruggedness. The types 

 in order of extent are grass 41%, Douglas 

 fir 23%, brush 8%, barren 8%, lodgepole 

 pine 6%, subalpine 6%, aspen 2%, west- 

 ern yellow pine 2%, miscellaneous small 

 types making up the balance. Graz-
