Accuracy Assessments of Airborne Hysperspectral Data for Mapping Opportunistic Plant Species in Freshwater Coastal Wetlands

Abstract:Airbome hyperspectral data were used to detect dense patches of Phragmites australis, a native opportunist plant species, at the Pointe Mouillee coastal wetland complex (Wayne and Monroe Counties, Michigan). This study provides initial results from one of thirteen coastal wetlands, field-sampled during Summer, 2001. Initial results are from airborne hyperspectral (PROBE-1) data acquisition and the data processing procedures that were performed in conjunction with wetland field sampling in two patches of Phragmites australis at Pointe Mouillee. The spread of Phragmites australis and other opportunistic plant species throughout the landscape is of concern to natural resource managers because it poses a threat to the biological diversity of wetlands. Research suggests that the establishment and expansion of such invasive and aggressive plant species may be the result of general ecosystem stresses. Thus, Phragmites australis may be an indicator of wetland condition. We used PROBE- I data as a first step in the semi-automated process of mapping the presence of Phragmites australis and its percent cover within large homogeneous patches, typical of some Great Lakes coastal wetlands. We discuss the results of this study in the context of long-term project goals of determining ecological relationships between: (1) landscape disturbances in the vicinity of wetlands; and (2) the presence and distribution of Phragmites australis within wetlands.
