Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler
Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler
Graduate Theses, Dissertations, and Problem Reports
Soils in the Monongahela National Forest (MNF) are acidic due to sandstone parent material, acid deposition, uptake of base cations by vegetation, and release of organic acids by organic matter (OM) decomposition. Increases in soil acidity have caused declines in forest health and changed species composition and nutrient status. Liming can neutralize soil acidity, but no large-scale liming projects have been done on acid forest soils in the USA. In anticipation of acquiring funding for a proposed liming project in the MNF, in 2007 and 2009 10 sites were selected to sample and analyze soils before lime was applied. In …
In-Stream Habitat Predicts Salamander Occupancy And Abundance Better Than Landscape-Scale Factors Within Exurban Watersheds In A Global Diversity Hotspot, Nathaniel Weaver, Kyle Barrett
In-Stream Habitat Predicts Salamander Occupancy And Abundance Better Than Landscape-Scale Factors Within Exurban Watersheds In A Global Diversity Hotspot, Nathaniel Weaver, Kyle Barrett
Publications
The southern Appalachian Mountains have experienced rapid human population growth rates since the 1980s. Land used practices are shifting from rural to residential. The majority of development has been low density, and is often near biologically diverse areas such as National Forests and National Parks. The long-term effects of urbanization in the southeastern Appalachian Mountains are not clearly understood and even less is known with respect to stream salamander response to urbanization. In order to determine the temporal influence of exurban housing on southern Appalachian streams we sampled 27 first- and second-order streams in watersheds containing exurban developments ranging in …
The Influence Of Exurban Landscapes And Local Site Characteristics On Riparian Vegetation, Nathan Weaver, Kyle Barrett, Don L. Hagan
The Influence Of Exurban Landscapes And Local Site Characteristics On Riparian Vegetation, Nathan Weaver, Kyle Barrett, Don L. Hagan
Publications
The southern Appalachian Mountains have experienced large population growth and a change in land use in the past 30 years. The majority of development has been low density, suburban land, known as exurban development. The long-term effects of exurbanization on riparian vegetative communities in the southeastern Appalachian Mountains are not well known. We sought to determine if vegetative community composition and structure change as a function of watershed–level variables such as time since neighborhood development or percent impervious surface within the watershed. We also assessed local–scale measures of disturbance such as canopy cover and basal area. Over two years we …
The Development Of Old-Growth Structural Characteristics In Second-Growth Forests Of The Cumberland Plateau, Kentucky, U.S.A., Robert James Scheff
The Development Of Old-Growth Structural Characteristics In Second-Growth Forests Of The Cumberland Plateau, Kentucky, U.S.A., Robert James Scheff
Online Theses and Dissertations
Prior to Euro-American colonization beginning in the late 1700s and subsequent periods of land conversion and intensive resource extraction, most forest on the Cumberland Plateau in Kentucky would have existed in a state meeting one or more of the definitions of old-growth forest in use today. However, many recovering, mature forests currently exist that might be redeveloping old-growth structure and function. To assess the development of old-growth forest characteristics in second-growth forests, 70 - 90 year old (young) and 140 - 160 year old (old) hardwood forests in the Daniel Boone National Forest were examined for a suite of structural …
