<P>Detailed and accurate information on the spatial distribution of individual species over large spatial extents and over multiple time periods is critical for rapid response and e?ective management of environmental change. The twenty first century has witnessed a rapid development in both ?ne resolution sensors and statistical theories and techniques. These innovations hold great potential for improved accuracy of species mapping using remote sensing. </P><I><P>Fine Resolution Remote Sensing of Species in Terrestrial and Coastal Ecosystems </I>is a collection of eight cutting-edge studies of ?ne spatial resolution remote sensing, including species mapping of biogenic and coral reefs, seagrasses, salt and freshwater marshes, and grasslands. The studies illustrate the power of fine resolution imagery for species identi?cation, as well as the value of unmanned aerial vehicle (UAV) imagery as an ideal source of high-quality reference data at the species level. The studies also highlight
