Everglades (Fla. )

The Miccosukee Tribe of South Florida is a federally recognized Indian tribe who reside on a reservation that lies within the Florida Everglades. As such, like many Indian tribes, their modern political history is entangled with the history of the creation of nearby national parks that were previously their traditional hunting territories. Since the beginning of the era of Everglades restoration and the rise in public policy designed to save the “River of Grass” from pollution, encroaching development, and eventual extinction, the Miccosukee have been on the front lines of trying to preserve the area they call home. While the Everglades means many different things to many different people, the Everglades to the Miccosukee Indians are the site and stakes of indigenous sovereignty. I argue that the issue of Everglades preservation is not just a matter of environmental conservation, but also a matter of fundamental human rights. Theoretically, I situate the debate surrounding the Florida Everglades within several theoretical paradigms, including the rights of indigenous peoples, the anthropology of development, and political ecology. I use anthropological research methods such as in-depth interviews with tribal officials and local environmental agencies to gain a complete picture of the current political landscape of the Everglades.

It is well known that biogenic gas emissions (mainly methane and carbon dioxide) vary both spatially and temporally in peatlands. While most studies have focused on northern systems, several recent studies in tropical and subtropical peatlands (like the Everglades) have revealed the presence of areas of increased gas accumulation and emissions, or hotspots, that may be related to physical and/or biogeochemical changes within the peat's matrix. However, these studies are often limited in terms of sampling volume and resolution or are based in laboratory studies that may not be totally representative of field conditions. In this study we investigate the spatial variability (both lateral and vertical) in gas accumulation and release at the field scale, over 10 m long transects at two locations in Water Conservation Area 1 of the Florida Everglades, using an array of hydrogeophysical methods. Resulting data infers the presence of hotspots with dimensions ranging from 1-2 m in width and approximately 0.5 m tall. These areas showed high variations in biogenic gas accumulation and release an order of magnitude higher than surrounding areas and occur seasonally as the highest gas releases were observed during Florida’s wet season. This study therefore has implications for better understanding the spatial and temporal variability of biogenic gas hotspots in peat soils, and how the matrix structure affects gas accumulation and release. This study shows the importance of considering the heterogenous nature of the peat's matrix when quantifying gas fluxes in the Everglades, and particularly when using methods with small sampling volumes like gas chambers.
