Correlations Between Soil Redness And Soil Properties That Affect Non-Native Annual Plant Distribution In Chaparral And California Sage Scrub, Madeline Blua

Electronic Theses, Projects, and Dissertations

Non-native annual plant species have degraded California Sage Scrub and chaparral and present obstacles to shrubland restoration. Red soil patches in chaparral and California Sage Scrub of San Bernardino and Riverside counties appear to support fewer non-native annual plants than non-red soils. The purpose of this study was to confirm differences in vegetation cover between red and non-red soils in shrublands and to use soil analyses to determine possible causes. During vegetation surveys conducted in April of 2018, it was confirmed that red soil sites had lower cover of non-native plants and higher cover of native plant species than the …

Geospatial Applications To Mitigate Concentrated Animal Feeding Operations From Impacting Surface Water Resources, Elias Rex

Electronic Theses, Projects, and Dissertations

Concentrated Animal Feeding Operations (CAFOs) offer the ability to meet the rising demands of population growth by housing large amounts of livestock on relatively small areas of land, using medication to accelerate their maturation, and reusing waste products as fertilizers. However, there is a growing abundance of literature related to land use configurations and their effects on water resources, many of which highlight agriculture as a primary contributor of nutrients and fecal bacteria found in surrounding water resources. The purpose of this study is to advance the current knowledge surrounding CAFO land-use and its effect on tributaries within the Cape …

Low Impact Development Best Management Practices Comprehensive Overview And Case Study, Graciela Rivera

Electronic Theses, Projects, and Dissertations

This project paper is an overview of the different types of best management practices (BMPs) that can be applied within a Low Impact Development framework. Low Impact Development (LID) is a type of stormwater management implementation that is growing in popularity. It allows developments to manage stormwater by working within established ecosystems to lessen environmental impacts. The cost and effectiveness of these practices are examined. In the first chapter, a comprehensive summary to LIDs and BMPs is presented.

The costs and effectiveness of bioretention, biofiltraion and infiltration basins, as well as permeable pavements, were studied and compared. The facility case …
