Close-Range Remote Sensing of Forest Structure for Biodiversity Assessments: A Systematic Literature Review

Abstract Purpose of Review Forest biodiversity is heavily influenced by structural conditions. In the past, forest stand structure was primarily quantified by traditional one- or two-dimensional metrics and indices. Close-range remote sensing enables researchers for the first time to reproduce and digitalize the three-dimensional structure of forests in high-resolution. The technological progress creates new possibilities in the field of biodiversity assessments. Since a structured overview of t
