Critical Biogeography: Vegetation Change, Rephotography, and Constructions of Nature in Yosemite's High Country

Abstract (Summary)

This work seeks to understand and analyze the biophysical, historical, and sociopolitical realities governing vegetation change in subalpine meadows within Yosemite National Park. The degree to which meadows have experienced or resisted conifer encroachment is a primary concern, both ecologically and socially, within this work. In order to understand the scale of these changes, fourteen locations were rephotographed, creating, in many cases, a visual lineage of over one hundred years. Supplementing the rephotography, quantitative data from belt transects and vegetation quadrat readings, along with soil pH, nitrogen, phosphorous, and potassium were gathered from five locations nested within rephotographs.

In hopes of broadening the contextualization and scope of scientific inquiry, the socioeconomic and political ramifications of this research are grappled with throughout. This follows in the tradition of critical physical geography and other such disciplines that attempt to locate the knowledge that they produce within the ontological framework that produced it.
