Individually located trees can provide useful information for monitoring deforestation and forest degradation. This thesis aimed to research the detection of individual trees from both Terrestrial and Airborne laser scanning data. Four different tree detection methods were executed. Three of the tree detection methods were based on tree top detection, peak tree top detection, neighbourhood maximum and height dependent treetop detection. One tree detection method was new and based on stem detection, which is called hollow tree stem detection.
