Production Ecology And Stand Dynamics Of Young Acadian Forest Stands In Response To Silvicultural Intensity And Compositional Objectives, Andrew S. Nelson
Production Ecology And Stand Dynamics Of Young Acadian Forest Stands In Response To Silvicultural Intensity And Compositional Objectives, Andrew S. Nelson
Electronic Theses and Dissertations
Early successional stands are common across the Acadian forests of eastern Canada and the Northeastern US. However, productivity and dynamics of these stands, as well as the underlying mechanisms influencing these processes, under different management scenarios are poorly understood. To address this need, I used a factorial experiment that controlled silvicultural intensity and species composition to quantify the effects of varying treatments on early stand dynamics, and the physiological and morphological factors influencing tree performance . Specifically, I studied: 1) species differences in aboveground allometrics, 2) light capture, light-use efficiency (LUE; growth/light capture), and foliar carbon isotope composition (δ13C) of …
Productivity Standards For Whole-Tree And Cut-To-Length Harvesting Systems In Maine, Patrick Hiesl
Productivity Standards For Whole-Tree And Cut-To-Length Harvesting Systems In Maine, Patrick Hiesl
Electronic Theses and Dissertations
The forest industry is a highly cost intensive business and therefore effective management is necessary. Information about productivity and time consumption of harvesting equipment in a variety of stand and site conditions can help operation managers to be efficient. In the state of Maine there have not been any productivity related publications within the past 25 years. Due to this lack of information and the need of information of productivity, especially in small diameter stands, the presented research developed. The focus of this study is on whole-tree harvesting systems including feller-buncher, grapple skidder and stroke delimber, as well as cut-to-length …
