RT Journal Article SR Electronic T1 How Trees Shape Urban Spaces: Multiplicity and Differentiation of the Urban Forest Viewed from a Visual-Spatial Perspective JF Arboriculture & Urban Forestry (AUF) FD International Society of Arboriculture SP 4 OP 17 DO 10.48044/jauf.2023.024 VO 50 IS 1 A1 de Wit, Saskia Irene A1 van der Velde, John René Timothy YR 2024 UL http://auf.isa-arbor.com/content/50/1/4.abstract AB Background The field of urban forestry encompasses many dimensions, of which that of visual-spatial perception, addressing the spatial relationship between city and trees, has received little attention. Analyzing the urban forest from a visual-spatial perspective is needed to understand relationships between different components as well as site-specific qualities.Methods Tree configurations describe the relationship between form and space, determined by the relative disposition of the trees which result from an interaction between design and the development over time. Based on field observations, with the city of Delft in the Netherlands as a case study, 35 generic tree configuration types have been defined. With this “vocabulary,” specific tree configurations and their relations are researched, describing the urban forest from an eye-level perspective as an essential level on which the spatiality of the urban forest can be understood.Results Unraveling the urban forest components by comparing two emblematic ensembles of tree configurations allows an understanding of their heterogeneity as well as their coherence and dynamics.Conclusions The relationship of the tree vocabulary with the specific location exposes their role as an ordering structure and a carrier of the identity of Delft, and their differentiation and site-specific qualities, revealing a composition of wooded areas each with their own characteristics, shows both urban and forested areas as equivalent components of an urban forest mosaic. This differentiation can be used as a tool for strengthening relations between the different components as well as diversity and heterogeneity in urban forests.
