This study analyses whether change detection techniques can identify vegetation changes in Macquarie Island, using high resolution Quickbird satellite imagery; it also takes fuzzy aspects of changes into account in order to explore and discover the uncertainty in the change detection outputs. As Macquarie Island has been severely affected by rabbit grazing, this study probes into the vegetation changes on it by different change detection techniques, with a view to help people make proper management strategies to protect Macquarie Island's unique environment. Besides, because of its geographically isolated location, monitoring changes on the Island is most efficiently achieved using satellite imagery. Traditional change detection techniques can distinguish change from no change in a binary way; incorporating fuzziness is a new approach for change detection as it extends the binary results to the fuzzy results by revealing the transitional nature of the natural environment in the most real way, thus a more ...
