A Watershed Prioritization Model For Community-Centered Riparian Forest Restoration In Tennessee, Madison Johnson
A Watershed Prioritization Model For Community-Centered Riparian Forest Restoration In Tennessee, Madison Johnson
Masters Theses
Riparian forests are unique ecosystems that act as transitional areas between land and water that are a vital part of a healthy and functional stream ecosystem. Due to the rapidly changing landscape, riparian forests are increasingly threatened by urban development, agriculture, and invasive species, which contributes to a trend of degrading water quality in Tennessee. To address declining riparian forest quality in the face of land-use changes, the purpose of this study was to develop a simple watershed prioritization model that identifies areas that are highly susceptible to poor water quality, and where riparian plantings would be most beneficial. This …
Structural Comparison Of Arctic Plant Communities Across The Landscape And With Experimental Warming In Northern Alaska, Jessica L. Gregory
Structural Comparison Of Arctic Plant Communities Across The Landscape And With Experimental Warming In Northern Alaska, Jessica L. Gregory
Masters Theses
Understanding vegetation change is central to forecasting the impacts of climate change. Percent cover, determined from a point frame method, is commonly used to monitor vegetation change. Cover is influenced by canopy structure which may change with the size (growth) or number (density) of individual plants. The overarching objective of this project was to document the relationship between vegetation cover and traits representing plant growth and density and determine if these relationships changed with warming. We used regressions and analysis of covariance to detect which of several traits was most strongly related to cover in vegetation at a wet and …
The Initial Effects Of Community Variables On Sand Prairie Restoration: Species Establishment And Community Responses, Robert Christopher Roos
The Initial Effects Of Community Variables On Sand Prairie Restoration: Species Establishment And Community Responses, Robert Christopher Roos
Masters Theses
We established a sand prairie restoration experiment in northern Lower Michigan’s pine-oak barrens to analyze the effect of different community variables (vegetative cover, species richness, biomass, diversity, and floristic quality) when comparing: (1) how our restoration efforts (seeded treatments) compare to natural community succession (control plots), (2) how different seeding treatments affect these community variables, specifically when evaluating (2a) the effect of grass seeding densities; and (2b) the effect of different forb guilds (early flowering, late flowering, and legumes) during the initial two growing seasons of restoration establishment. In general, a comparison between seeded treatments and non-seeded control treatments indicates …
