The Sampling, Pattern, And Survival Of The Higher Elevation Beech In The Great Smoky Mountains, Kye Chil Oh

Doctoral Dissertations

Six "beech gap" forests in the Great Smoky Mountains between Tennessee and North Carolina were sampled for pattern of stem distribution and for stem size and survivorship of Fagus grandifolia. Several methods for approximating the adequacy of number of plots for stem count were compared in terms of relative efficiency. Stem count and basal area of all species were similar between north-facing and south-facing stands, and between more east-facing and west-facing sides of the same stand. Mean density of live beech ranged from 3705 to 7835 trees per hectare, and basal area ranged from 16.1 to 33.0 m^{2 …}

Bryoecology Of The Appalachian Spruce-Fir Zone, Daniel Howard Norris

Doctoral Dissertations

Introduction: Ecological investigation of an area ordinarily follows a certain course. First explorations attempt to discover the nature of the flora, and ecological information is incidental to the habitat notes of collected species. Later, general qualitative observations appear regarding he vegetation of particular habitats. Only after this is a quantitative study using quadrats or other sampling techniques begun, and this quantitative work lays the foundation for future autecological, ecosystem and productivity work. Traditionally the above course is followed first by workers in vascular plant ecology, and studies of cryptograms are seldom as far advanced as that of the spermatophytes.

Vegetational Succession On Three Grassy Balds Of The Great Smoky Mountains, Mary Ellen Bruhn

Masters Theses

Introduction: The Great Smoky Mountains Conservation Association recently requested that the National Park Service take steps to preserve three grassy balds (Andrews Bald, Spence Field, and Gregory Bald) of the Great Smoky Mountains by preventing the invasion of woody vegetation on these balds. The National Park Service requested that the University of Tennessee Department of Botany look into the problem and thus the problem was brought to the attention of the author by Dr. E. E. C. Clebsch.

This is a study of vegetation change on these three grassy balds. Special interest is given to the rate of encroachment of …
