The effects of timber and fire management contribute to natural hillslope processes that continue down slope into the stream network. I am interested in the linkages that exist between these hillslope processes (human and non-human origins) and the dynamic diversity of riparian forests.
Thanks to the S.U. Department of Geography I was able to travel to my study site and spend the entire summer of 2011 conducting preliminary research. I spent over sixty nights in a tent along the banks of the South Fork of the Trinity River in northern California. Upon submerging into the lush riparian forests that surround the stream network I gathered empirical evidence necessary to begin answering some of my research questions. This first step has led me along a path of understanding what patterns of riparian diversity exist throughout a stream network. At the basin scale, I found significant increases in riparian diversity near tributary junctions; and at the reach scale I found specific (and very surprising) patterns of species diversity in the areas around tributary junctions.
With continuing support from the S.U. Department of Geography I will continue my field research this summer. I plan to expand into the Trinity River watershed, investigating similar trends in both damned and undammed rivers with varying upland land cover histories.
