Abstract: We used lightweight UAV carrying mirrorless camera to shoot the canopy landscape of subtropical forest, and found that only 3 canopy species can be recognized at 100 m flight height, but almost 20 canopy species can be done at 50 m flight height by analyzing the canopy outlines, textures, structures and colors. Even some understory species can be distinguished. These results can provide much canopy species information and be useful for forest protection or ecosystem management.
