Vegetation is used by landscape planners and designers to reduce the visual impact of buildings. The choice of
the species to be used depends on the characteristics of the crown canopy filtering. Nevertheless, the
information on crown canopy filtering is scarce. This work examines the degree of filtering in canopy
architecture of Quercus pyrenaica. The district of the Ambroz Valley, in Cáceres Province was chosen as the
experimental area for the purposes of this research, and here Quercus pyrenaica were chosen as the most
representative species. Two methods were selected for this study: hemispheric photography and vertical
photography. All data was gathered during the summer as this is when the canopy of the species analyzed
reaches its maximum leaf area index. The main aim of this research is to compare the hemispherical
photographic method for calculating the amount of light that passes through the canopy, with that of vertical
photography to obtain filtering percentages in plants.info:eu-repo/semantics/publishedVersio
