Patterns Of Regeneration Of Eastern White Pine (Pinus Strobus L.) As Influenced By Large Isolated Reserve Trees And Precommercial Thinning, Kate E. Zellers
Patterns Of Regeneration Of Eastern White Pine (Pinus Strobus L.) As Influenced By Large Isolated Reserve Trees And Precommercial Thinning, Kate E. Zellers
Electronic Theses and Dissertations
The spruce budworm epidemic of the 1970s and 1980s led to the salvage harvesting of spruce-fir stands, serving as a release for scattered immature eastern white pine (Pinus strobus L.) trees. These pines are now growing as large isolated reserve trees above a mixed conifer regeneration stratum. The objectives in this study were to determine any effect of varying levels of basal area (m2 ha-1) of large pine reserve trees may have on (1) the densities (stems ha-1) of both eastern white pine and non-pine species in the developing regeneration stratum, and (2) the …
The Growth, Yield, And Financial Performance Of Isolated Eastern White Pine (Pinus Strobus L.) Reserve Trees, Christopher E. Zellers
The Growth, Yield, And Financial Performance Of Isolated Eastern White Pine (Pinus Strobus L.) Reserve Trees, Christopher E. Zellers
Electronic Theses and Dissertations
The ability of eastern white pine (Pinus strobus L.) to persist as emergent trees makes this species well suited to silvicultural systems in which they are retained as isolated reserves after a regeneration harvest. While such systems are implemented throughout the Acadian spruce-fir region of Maine, little is known about the growth response and financial performance of eastern white pine following complete release from competition. In this study, 77 trees from 8 sites throughout the Acadian spruce-fir region were sampled tree and crown measurements, and increment cores were extracted at breast height, as well as from the top of …
Monitoring Vegetation Change By Using Remote Sensing: An Examination Of Visitor-Induced Impact At Cadillac Mountain, Acadia National Park, Min Kook Kim
Electronic Theses and Dissertations
Cadillac Mountain, the highest peak along the eastern seaboard in the United States, is a major visitor destination at Acadia National Park. Managing vegetation impact on the summit of Cadillac Mountain is extremely challenging given the number of users and dispersed nature of visitor use at this fragile environmental setting. Since 2000, more intensive management strategies based on placing physical barriers to protect threatened vegetation and leave no trace signs have been employed to reduce vegetation impact and enhance vegetation recovery in the vicinity of the summit loop trail. A number of different change detection techniques and high resolution remote …
