Therefore, it is often important to systematically monitor the spread of species over a broad region. Remote sensing has been an important tool for large-scale ecological studies in the past three decades, but it was not commonly used to study alien invasive plants until the mid 1990s. We synthesize previous research efforts on remote sensing of invasive plants from spatial, temporal and spectral perspectives. We also highlight a recently developed state-of-the-art image fusion technique that integrates passive and active energies concurrently collected by an imaging spectrometer and a scanning-waveform light detection and ranging (LiDAR) system, respectively. This approach provides a means to detect the structure and functional properties of invasive plants of different canopy levels. Finally, we summarize regional studies of biological invasions using remote sensing, discuss the limitations of remote sensing approaches, and highlight current research needs and future directions.<\/jats:p>","DOI":"10.3390\/s90604869","type":"journal-article","created":{"date-parts":[[2009,6,19]],"date-time":"2009-06-19T10:01:24Z","timestamp":1245405684000},"page":"4869-4889","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":255,"title":["Applications of Remote Sensing to Alien Invasive Plant Studies"],"prefix":"10.3390","volume":"9","author":[{"given":"Cho-ying","family":"Huang","sequence":"first","affiliation":[{"name":"Department of Geomatics, National Cheng Kung University, Tainan 70101, Taiwan"},{"name":"Office of Arid Lands Studies, University of Arizona, Tucson, AZ 85719, USA"}]},{"given":"Gregory  P.","family":"Asner","sequence":"additional","affiliation":[{"name":"Department of Global Ecology, Carnegie Institution for Science, Stanford, CA 94305, USA"}]}],"member":"1968","published-online":{"date-parts":[[2009,6,19]]},"reference":[{"key":"ref_1","unstructured":"Parry, M.L., Canziani, O.F., Palutikof, J.P., van der Linden, P.J., and Hanson, C.E.
