The first type, the spruce woodland on the southern bases of hills (Fig. 36) and on south facing slopes in valleys (Figs. 37 and 38), is distinctive. This woodland is made up of isolated stands which vary in size from a few trees to rather extensive forests. Southward, in Old Crow Flats, the stands on hills tend to be- come continuous with the parkland tundra and riparian wo(k1s (Fig. .39). The species composi- tion in the spruce stands is the same as that of the parkland tundra, differing mainly in the fre- (juency of species encountered. In both the dom- inant tree species is the white spruce, Picea f^latica. The riparian woods (Figs. 40, 41, 42, and 43) are distinct even though they grade into both of the other tvpes of woodland. White spruce is the dominant conifer, and other tree species are represented by white l^irch, Betula /^ f" , y / Fic. 20. Unnamed lakes in Old Crow I'lat about 16 miles soutli of Sam Lake.
