Watershed segmentation by means of raster lidar image has potential to demarking the tree crown from the lidar image. Limited studies on lidar application to estimate tree crown in forest of Borneo motivated this study. This study focuses to estimate the tree crown using the watershed segmentation method from the measured lidar data over the Bukit Hitam Forest Reserve in Limbang, Sarawak. The tree crown extraction accuracy is about 5 meter radius and the tree height about 2.5 meter. Some recommendations are highlighted to increase the accuracy in the future. Keyphrases: Crown size, LiDAR, Tropical rain forest, forest, tree height
