Tracking the long-term structure changes of a mature deciduous broadleaf forest stand using digital hemispherical photography

Abstract: Hemispherical photography provides permanent records of forest canopy structure. We analysed digital hemispherical images taken during the period of 2007–2018 in a mature silver birch stand located in Järvselja, Estonia. The stand was thinned in 2004. Understory trees were removed in the spring of 2018. Images were processed using the LinearRatioSC method. Effective plant area index Leff during the leafless phenophase increased as a result of tree growth from 0.92 to 1.24 and understory cutting was not detecta… Show more

“…Since 2007, regular measurements of canopy gap fraction have been carried out in the stands (Lang et al, 2010;Lang et al, 2017;Kuusk et al, 2018;Lang & Pisek, 2019). There have not been any substantial stand structure alternating disturbances in the stands.…”
