Plants and Animals of Mount Marcy, New York, Part I

Berkshire Plateau Vegetation, Massachusetts

“…As characterized by its predominant species, this herb layer, as well as the associated tree layer, is strikingly similar to that of other northern hardwood areas, as described by Hill ( 1923) for the Penobscot Bay region of Maine, by Nichols (1918) for Cape Breton island, Nova Scotia, by Adams et al ( 1920) for the Adirondacks in the vicinity of M t. Marcy, and by Hough ( 1936) for northwestern Pennsylvania. In the case of the glacial podzol Kennan soils of \Visconsin, \Vilde ( 1934) has found that "the moderately acid phase of these soils is characterized by reactions of pH 5.5 to 6.5, with extremes of pH 5.0 to 6.8, and supports an association of minimiacidophilous plants, such as maidenhair fern, sweet cicely, meadow rue, water leaf.…”

A Comparison of Virgin Spruce‐Fir Forest in the Northern and Southern Appalachian System

“…Even in those times, the montane spruce-fir of Picea rubens and Abies fraseri may have been somewhat different in composition from the surrounding lowland boreal forest since Brown ( 1938) reports macrofossils of Picea glauca and Thuja occidentalis from Louisiana, and Potzger and Tharp ( 1947) identify Pie ea glauca, P. maria11a, and Abies pollen in a deep bog in south central Texas. During the cooler periods of the Pleistocene, the forests of much of southeastern North America may have resembled the present situation in northern New England (Harvey 1903;Harshberger 1905;Adams et al 1920;Moore and Taylor 1927) with a red spruce-fir forest confined largely to the mountains and surrounded by a forest dominated by fir and hardwoods with black spruce and white spruce in the colder lowland hrgs and also near timberline.…”

Vegetation, Soil, and Climate on the Green Mountains of Vermont

“…considered to he at the elevation where maple, beech. hemlock, and pine cease to grow, were about 1,000 ft (304 m) higher than the upper limit of the hardwood zone in the Adirondacks noted by Adams et al (1920). Zone E of Bray (Canadian Zone) was the red spruce~ balsam fir forest above the hardwood forest.…”
