Identifying Invasive Weed Species in Alpine Vegetation Communities Based on Spectral Profiles

This study examined the use of hyperspectral profiles for identifying three selected weed species in alpine region New South Wales, Australia. The targeted weeds included Orange Hawkweed, Mouse-ear Hawkweed and Ox-eye daisy, which have caused a great concern to regional biodiversity health environment Kosciuszko National Park. Field surveys using spectroradiometer were undertaken measure leaves flowers companion native plants. Random Forest (RF) classification was then applied distinguish spectral bands would differentiate from Our results showed that an accuracy 95% achieved if distinct considered, 80% only considered. Emulation two multispectral sensors (Sentinel-2 Parrot Sequoia) conducted investigate whether could potentially be wider bands.
