Forest Harvest Equipment Movement And Sediment Delivery To Streams, Daniel Whiteside Bowker
Forest Harvest Equipment Movement And Sediment Delivery To Streams, Daniel Whiteside Bowker
Theses and Dissertations--Forestry and Natural Resources
Streamside management zones (SMZs) have become important management techniques to prevent the introduction of sediment to stream networks. This study examined the current Kentucky best management practice (BMP) guidelines for SMZs by outfitting mobile forest harvest equipment with global positioning system (GPS) receivers, enabling modeling of equipment traffic and spatial analysis of stream sediment delivery. Three SMZ configurations were implemented during commercial timber harvest, along with four different techniques of crossing ephemeral channels, in order to determine where and why sediment was introduced to the stream network. Results indicate that increasing the SMZ buffer width leads to decreased sediment delivery, …
Effects Of Streamside Management Zone Timber Harvest On Salamander Communities In Robinson Forest, Thomas Maigret
Effects Of Streamside Management Zone Timber Harvest On Salamander Communities In Robinson Forest, Thomas Maigret
Theses and Dissertations--Forestry and Natural Resources
Salamanders are critical components of forest ecosystems, in terms of total biomass, as well as for their value as indicators of ecosystem stress. Considering the worldwide decline in amphibian populations, the known effects of timber harvest on salamander populations, and the importance of the forest products industry in Kentucky and elsewhere, the impacts of silvicultural operations on salamander communities cannot be overlooked. The objective was to investigate the effects of three different silvicultural treatments, each involving different streamside management zone (SMZ) characteristics, on salamander communities in ephemeral streams. Data were collected by regular checks of pitfall traps, coverboards, and transect …
Carbon Life-Cycle And Economic Analysis Of Forest Carbon Sequestration And Woody Bioenergy Production, Prativa Shrestha
Carbon Life-Cycle And Economic Analysis Of Forest Carbon Sequestration And Woody Bioenergy Production, Prativa Shrestha
Theses and Dissertations--Forestry and Natural Resources
Sequestering carbon in standing biomass, using woody bioenergy, and using woody products are the three potential ways to utilize forests in reducing greenhouse gases (GHGs) and mitigating climate change. These forestry related strategies are, however, greatly influenced by the existing markets and market based policies. This study focuses on the first two forest strategies. It investigates the combined impact of carbon and woody bioenergy markets on two different types of forests in the US – oak dominated mixed hardwood forests in the Central Hardwood Forests Region and loblolly pine forests in the southeastern US. A modification of the Harman model …
