JI6 COMMISSI OX OP CONSERVATIOX Merchantable Timber Of the 3,921 square miles below the merchantable timber-line, a!! but 1,066 square miles is considered capable of carrying timber. The titiit)ci growth that once partially covered the valleys of the region has been badly burned, and large areas are now covered with a second-growth of willow and poplar. Other areas are reproducing with lodgepole pine, with or without a mixture of white spruce. In places, there are patches where the soil coudi. tions are too wet to support forest growth. The bottoms of the U-shaped valleys, at the headwaters of the Stikine, are swampy, but their slopes are clothed with a forest of spruce and alpine fir, extending up to timber-line. Around Telegraph Creek, the climate is arid, and there are areas alonjj the Stikine where the conditions are too dry to support tree growth, especially on southern exposures. Nevertheless, at a short distance from Telegraph Caek, at higher altitudes, and even along the river on northern exposures, then- are patches of timber, mostly second growth. The amount of merchantable timber, by species, in the Stikine- Unuk drainage basins is as follows : Hemlock, 1,189,440 ; balsam, 284,640 ; spruce, 1,038,720 ; lodKtpole pine, 99,840 ; cottonwood, 84,960 ; total, 2,697,600 Along the Unuk and the lower courses of the Stikine and the Iskut, where the coastal climate prevails, hemlock-Sitka spruce is the principal forest type. The flood plains of these rivers carry rather heavy stands of cottonwood. In the interior, the principal types are the white spruce-alpine fir and the lodfje- pole pine types. On the richer soils of the valleys of the plateau, groves of poplar and dense thickets of willow prevail wherever fires have completely destroyed the original forest growth. There are no saw-mills within the
