Cover Story: After patch- or clear-cut harvesting, the stumps represent a legacy of the trees that once stood there. In this research, we developed and tested a novel method to detect, segment, classify and measure tree stumps from unmanned aerial vehicle (UAV) imagery. This was done to assess how much stand information could be regenerated. Our trials show that it is indeed possible to capture a range of information on the basis of images from inexpensive UAVs. This information may be useful for a variety of applications. Among these, the possibility to obtain information on the spatial distribution of pathogens such as root- and butt-rot within a stand has great potential in providing decision support in mitigating the negative effects of these pathogens in future tree generations.
