Figure 48.—Barrens in mountains north of Barrasois River (Scotch- man's Barren); vegetation closely approximating heath; tamaracks in left foreground and mid-distance. that of the highlands as a whole is somewhat analogous to the relation between the edaphic formation-complex of the New Jersey pine barrens and that of the whole state of New Jersey. The character of the vegetation in the barrens is attributable very largely, directly or indirectly, to conditions of exposure, topography, and soil. Along the streams the climax forests of the forested area extend into the heart of the barrens, while, conversely, in high, exposed situations the vegetation of the barrens reaches well toward the coast. Forest resources of the region.—In summing up the results of a timber survey of this region, made a number of years ago,.
