Planting And Production Of Switchgrass (Panicum Virgatum L.) As A Bioenergy Crop In Michigan's Upper Peninsula, Kassidy Nikole Yatso Jan 2011

Planting And Production Of Switchgrass (Panicum Virgatum L.) As A Bioenergy Crop In Michigan's Upper Peninsula, Kassidy Nikole Yatso

Dissertations, Master's Theses and Master's Reports - Open

Switchgrass (Panicum virgatum L.) is a perennial grass holding great promise as a biofuel resource. While Michigan’s Upper Peninsula has an appropriate land base and climatic conditions, there is little research exploring the possibilities of switchgrass production. The overall objectives of this research were to investigate switchgrass establishment in the northern edge of its distribution through: investigating the effects of competition on the germination and establishment of switchgrass through the developmental and competitive characteristics of Cave-in-Rock switchgrass and large crabgrass (Digitaria sanguinalis L.) in Michigan’s Upper Peninsula; and, determining the optimum planting depths and timing for switchgrass in …


Will Whole-Tree Harvest Of Jack Pine (Pinus Banksiana) Deplete Soil Nutrients In Low-Productivity Sand Soils?, Victoria L. Veach Jan 2011

Will Whole-Tree Harvest Of Jack Pine (Pinus Banksiana) Deplete Soil Nutrients In Low-Productivity Sand Soils?, Victoria L. Veach

Dissertations, Master's Theses and Master's Reports - Open

In 2009 and 2010 a study was conducted on the Hiawatha National Forest (HNF) to determine if whole-tree harvest (WTH) of jack pine would deplete the soil nutrients in the very coarse-textured Rubicon soil. WTH is restricted on Rubicon sand in order to preserve the soil fertility, but the increasing construction of biomass-fueled power plants is expected to increase the demand for forest biomass. The specific objectives of this study were to estimate biomass and nutrient content of above- and below-ground tree components in mature jack pine (Pinus banksiana) stands growing on a coarse-textured, low-productivity soil, determine pools …


Comparing Remote Sensing And Ground-Based Methods Of Quantifying Cover Type And Carbon Storage In An Urban Forest, Christine L. Jones Jan 2011

Comparing Remote Sensing And Ground-Based Methods Of Quantifying Cover Type And Carbon Storage In An Urban Forest, Christine L. Jones

Dissertations, Master's Theses and Master's Reports - Open

Understanding the canopy cover of an urban environment leads to better estimates of carbon storage and more informed management decisions by urban foresters. The most commonly used method for assessing urban forest cover type extent is ground surveys, which can be both timeconsuming and expensive. The analysis of aerial photos is an alternative method that is faster, cheaper, and can cover a larger number of sites, but may be less accurate. The objectives of this paper were (1) to compare three methods of cover type assessment for Los Angeles, CA: handdelineation of aerial photos in ArcMap, supervised classification of aerial …


0784: L. D. Fowler Papers, 1900-1920, Marshall University Special Collections Jan 2011

0784: L. D. Fowler Papers, 1900-1920, Marshall University Special Collections

Guides to Manuscript Collections

The papers in this collection are both the professional and personal records of L.D. Fowler from 1900-1920 while working out of Durbin, WV. As an employee of the Pocahontas Tanning Company, L.D. Fowler’s business papers relate primarily to timber and the acquisition of bark associated with the tanning process. Among the type of materials included in the collection are correspondences (i.e. letters, telegraphs, and postcards), well-documented business transactions with a wide range of business partners, business cards, diaries, maps, popular culture items (calendars, etc.), and materials related to legal issues and political affiliations. This collection is divided into two overarching …


Effects Of Midstory Removal On Black Oak (Quercus Velutina) And White Oak (Quercus Alba) Regeneration, David Lee Parrott Jan 2011

Effects Of Midstory Removal On Black Oak (Quercus Velutina) And White Oak (Quercus Alba) Regeneration, David Lee Parrott

University of Kentucky Master's Theses

The formation of dense understories in eastern forests has created low light environments that hinder the development of advance oak reproduction. Studies have shown that a midstory removal can enhance these light conditions and promote the development of competitive oak seedlings. Previous studies have been primarily focused on oaks found on productive sites, and there is little knowledge of this treatment’s potential on intermediate sites and the typically associated oak species. This study investigates the seven-year effects of midstory removal on natural and underplanted white (Quercus alba L.) and black oak (Quercus velutina L.) reproduction, as …
