Two ecoregions in the zone. Characteristic trees. Shrubs and ground plan ts. Silviculture. The District is bounded on the north and west by coniferous forest on less rolling land, swept by continuous light winds and cooler temperatures from the Gulf of St. Lawrence. The soils are mainly loams and sandy Ioams of high fertility derived from red micaceous sandstones (Whiteside, 1950). Coarser soils derived from sandstone and conglomerate occur in the southeast. White pine is widespread on light soils and, with red pine, should be favoured on abandoned lands of this type. Pure stands of white spruce occur on old fields of heavier texture; this species appears to be well suited to the District, especially in view of its resistance to wind desiccation. [pp. 113—14] RED SPRUCE — HEMLOCK — PINE ZONE This Zone combines the two Ecoregions in the Maritime provinces in which red spruce and hemlock attain their greatest prominence. One [the Clyde River — Hal/fax ecoregion] includes most of the interior of western Nova Scotia, where red oak is a common associate; the other [the Maritime Lowlands Ecoregion] occupies much of the lowland of central Nova Scotia and eastern New Brunswick [plus Prince Edward Island]. Heavy soils and imperfect drainage prevail in the latter Ecoregion; sandy, generally shallow soils in the former. Red spruce and hemlock have been depleted in both, but remnants of old—growth forest indicate the former importance of these two species. It is the forests of this zone which, more than any other, represent a distinctive forest in the Maritime Provinces. (pp. 125-26] Maritime Lowlands Ecoregion Red spruce, black spruce, balsam fir, red maple, hemlock and white pine comprise a distinctive forest association on the gentle relief of the lowlands in all three Maritime Provinces. Jack pine is abundant on sandy soils, and black spruce swamps and peat bogs cover extensive areas. Red maple and wire birch, rather than red oak, predominate as fire types. Beech often forms pure stands on exposed ridges, with scattered spruce and fir, but sugar maple and yellow birch may be found on the larger hills. The lesser vegetation of this Ecoregion reflects the generally poor drainage and repeated cutting and burning. Witherod and rhodora are the common shrubs in areas of repeated disturbance; in places they may so effectively control a site that they exclude the softwood regeneration. Sheep laurel, mountain—holly and speckled alder are other aggressors. Common smaller plants include Wintergreen, gold-thread, naked miterwort, bunchberry, bristly clubmoss, sphagnum and Schreber's moss. Mountain maple, wood fern and wood-sorrel are present, but not as abundant as in the more humid Ecoregions. The relatively clean forest floor under white pine, spruce, fir and cedar on a moderately well—drained loam is illustrated in Fig.17 [not included here]. Problems in the silviculture of this Ecoregion lie in the conversion of wire birch and shrub—covered waste lands to suitable softwood species and in the establishment of a suitable pine on the sandy soils where jack pine once predominated. Black spruce regenerates on these sites, but does not grow as well as the pines. Nickerson (1956) has suggested that in addition, it may be detrimental to the soil. Most of the land dominated by shrubs is poorly drained, but appears to be a good site for the spruces. Remnants of the oldest stumps on some of these sites have been identified as pine, hemlock and cedar. 26
