Derivative spectroscopy of hyperspectral reflectance data of grassland vegetation was used to extract the wavelength peaks of different grass species of Xilinhot, Inner Mongolia, China. Caragana microphylla , which is characteristic of dry areas, was successfully detected among the four dominant grass species found in the typical Xilinhot grassland, using fourth-derivative peaks around 670 nm and 720 nm. A radiative transfer simulation showed that the identification scheme was not distorted by the atmosphere during airborne remote sensing. This suggests that high-order derivative spectroscopy of hyperspectral reflectance data from grassland vegetation can be an effective tool for advanced mapping and for the monitoring of grasslands.
