Remote sensing of rangeland biodiversity. Book Chapter. Vol. II, p. 277-307. Interpretive Summary: Technical Abstract: Rangelands are managed based on state and transition models for an ecological site. Transitions to alternative ecological states are indicative of degrading rangelands. Three key variables may be remotely sensed to detect transitions between alternative states: amount of bare soil, presence of invasive weeds, and plant species diversity. We compare three broad categories of remote sensing with optical sensors: high spectral resolution (hyperspectral), high temporal resolution (MODIS), and high spatial resolution (aerial photographs). While all three categories are capable of remote sensing transitions among states, we find that high spatial resolution is generally the best. However, to make use of these data, new techniques of image processing based on advances in computer vision are necessary. |
