This project examines the potential to use remote sensing for monitoring of the distribution of several weed species in the alpine region of NSW, specifically targeting Orange Hawkweed, Mouse-ear Hawkweed and Ox-eye Daisy, as requested by NPWS. The project is based on the premise that plants
absorb and reflect different amounts of different wavelengths of light in the visible and near infrared spectra, which can be plotted as spectral reflectance profiles. We aimed to determine whether the spectral profiles of the weeds were separable from the spectral profiles of other common co-occurring native plants, and if so, determine whether it was possible to detect the weeds using spectral sensors attached to a drone, and/or using high-resolution satellite imagery.
