Kentucky Forestry Economic Impact Reports
Forests cover nearly one-half of Kentucky and provide a wide range of both economic and non-economic benefits to the Commonwealth. The primary economic contributor is derived from the utilization of timber and wood resources. Analysis of Kentucky’s forest and wood industries in 2015 indicated an estimated direct economic impact of $9.1 billion (up 9 percent from 2014). These industries employed over 28,000 individuals. Total economic impacts in 2015 were estimated above $14 billion for the first time ($14.6 billion) with a total employment of 62,445. This increase in both direct and total impacts has been on-going since 2012 with a …

Soil Organic Matter Distribution In A Douglas-Fir-Tanoak Forest, Humboldt County, California, Hollie A. Ernest
Cal Poly Humboldt theses and projects
Soil carbon (C) affects the active gases in the atmosphere, nutrient cycling, and diversity of flora and fauna. Soil organic matter (SOM) is partially comprised of C, and a widely-accepted ratio of 0.58 organic carbon (OC) to organic matter (OM) is used to measure soil C on a landscape scale. However, this ratio varies according to vegetation, depth, hydrology, and may lead to miscalculations of soil C and SOM estimates. Soil C and SOM are inherently complex and it is not completely understood which environmental factors have the most influence in their formation, which occurs on a time scale of …
Quantifying Effects Of Quaking Aspen Silvicultural Treatments On Aspen Regeneration And Residual Growth, Philip W. Williams
Quantifying Effects Of Quaking Aspen Silvicultural Treatments On Aspen Regeneration And Residual Growth, Philip W. Williams
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Many quaking aspen (Populus tremuloides) populations are in decline across the western United States, a trend likely driven by ongoing climate change and past management that has led to increased competition with conifers. Restoration of aspen is a management goal potentially achievable through active forest management, but treatment effects on regeneration and residual growth have not been comprehensively studied. This project examined if removal of competing conifers altered aspen regeneration density, ungulate browsing, and residual adult aspen diameter growth using a control-impact study design. Sampling occurred at the Burnt Fork (ten treatments, four controls) and Bandy (seven treatments, four controls) …
