Spectral Discrimination Of Phragmites Australis At Different Phenological Stages In Saginaw Bay, Michigan, Trenton Benedict

Masters Theses

Michigan Great Lakes wetlands are among Michigan’s most significant bio-diversified ecosystems. One threat to this ecosystem is invasive species. Phragmites australis is one of these invasive species creating problems in the wetlands. Identifying Phragmites through satellite imagery creates difficulties in discriminating Phragmites from other vegetation accurately. This study used an ASD HandHeld 2 field spectroradiometer to identify the phenological spectral properties between Phragmites and cattails. The Euclidean distance was analyzed the spectral curves from the spectroradiometer to determine the separability between Phragmites and cattails. The largest Euclidean distance determined the best month to separate the spectral signatures of Phragmites and …
