The Influence Of Hydrogeomorphology, Soil Redox Conditions, And Salinity On The Spatial Zoning Of Saltgrass, Salt Rush, And Cattails In Scotts Creek Marsh, Swanton Pacific Ranch, Ca, Mark D. Gormley Dec 2013

The Influence Of Hydrogeomorphology, Soil Redox Conditions, And Salinity On The Spatial Zoning Of Saltgrass, Salt Rush, And Cattails In Scotts Creek Marsh, Swanton Pacific Ranch, Ca, Mark D. Gormley

Master's Theses

Scotts Creek Marsh (SCM) is a small coastal wetland ecosystem in Davenport, CA. The vegetation of SCM is dominated by three halophytic zones comprised of saltgrass, salt rush, cattails. The objectives of the study were (i) to investigate the variables that influence the zoning of the three dominant halophyte communities in SCM and (ii) to the test the effectiveness of Indicator of Reduction in Soil (IRIS) tubes to indicate the reduction of S. The study examined the following parameters from April 6 to July 21, 2013: (i) the HGM of Scotts Creek Marsh, (ii) soil oxidation and reduction (redox) conditions, …


Road Cuts And Atterberg Limits Of Little Creek Road, Christopher A. Marquis Oct 2013

Road Cuts And Atterberg Limits Of Little Creek Road, Christopher A. Marquis

Natural Resources Management and Environmental Sciences

This senior project examined road cuts and soil adjacent to the road cut, along Little Creek road. Contrasting a landslide hillslope complex to a hillslope drainage complex, the project also compared the organic soil horizon to the mineral soil horizon in both soil units. The soils were analyzed using qualitative and quantitative measures of soil properties. The project utilized a road cut inventory to note the characteristics of the road cut such as presence of rill erosion, rock outcrop and sloping degree of the road cut. The project derived the plasticity index for both organic and mineral horizons, and compared …
