Abstract/Description
-
A spatial analysis of vegetation community changes over time at the Arthur R. Marshall National Loxahatchee Wildlife Refuge will be conducted in order to identify relationships with variations in water level and water quality. The analysis will use existing current and historical data in the refuge, including water gages, vegetation surveys, fire burn data, Lidar based digital elevation data and aerial photography acquired from the United States Fish and Wildlife Service, Everglades Depth...
Show moreA spatial analysis of vegetation community changes over time at the Arthur R. Marshall National Loxahatchee Wildlife Refuge will be conducted in order to identify relationships with variations in water level and water quality. The analysis will use existing current and historical data in the refuge, including water gages, vegetation surveys, fire burn data, Lidar based digital elevation data and aerial photography acquired from the United States Fish and Wildlife Service, Everglades Depth Estimation Network EDEN, South Florida Water Management District and other sources. Understanding how vegetation boundaries and dominant species shift over time in response to water level changes and other hydrological factors will allow the National Wildlife Refuge, and other scientists, to create more responsive conservation and maintenance plans for the wetland refuge.

Show moreGlobal climate change stressors downscale to specific local vulnerabilities, thus requiring tailored adaptation strategies. Southeast Florida is uniquely vulnerable in terms of exposure to sea level rise due to low-lying porous limestone geology, high-valued coastal properties, treasured ecosystems, and dense populations at risk. Coastal populations are particularly at risk due to erosion, inundation and storm surge, but interior populations are also susceptible to rising water tables and extended periods of inundation amplified by SLR. Robust SLR adaptation options require significant economic costs that people may not be willing to pay for if they do not understand their real risk. If perceived risk does not adequately line up with actual risk, the necessary strategies may not be implemented.
This study aims to compare perceived risk to actual risk to sea level rise in Broward County, FL. Perceived risk of residents, measured via an online survey, was layered over actual risk in terms of flooding, storm surge, and loss of property. Using GIS, a coastal vulnerability index was constructed for the actual risk, and principal component analysis identified the key factors influencing perceived risk. Results show where risk is underestimated, realistic, or overestimated, quantified both spatially and demographically. The concerns of residents are misaligned with the true vulnerability on many impacts, while others were very accurately understood. There are many opportunities for resilience that require preparation and adaptation. The first step to solving a problem is acknowledging that it exists. Where should outreach be targeted for increasing awareness?
