Together with landscape architecture scholars Saskia de Wit and René van de Velde of TU Delft, Lisa Diedrich has edited a thematic issue of SPOOL on designerly research approaches to urban forestry, now published in an Open Access format. The issue brings together scholars from all over Europe and sheds light on a wide range of artistic, urbanistic, arboristic and historic perspectives on urban forests as a landscape architectural figure of thought and spatial reality to be further elaborated in support of a more sustainable way of living with an urbanising planet.

The SPOOL issue will be launched during the 2025 European Forum on Urban Forestry (EFUF) conference in Zurich, 3-7 June 2025:

This issue of SPOOL elaborates a designerly perspective on urban forestry. Evidence has increased rapidly in the recent years to confirm the agency of trees and urban forests to cure a number of ills besetting urban societies. An expanding range of disciplines, in varying and novel combinations, are turning to an urban version of forestry to re-configure green (and grey) infrastructures, re-write neighbourhoods, re-purpose derelict territories and re-vitalize disparate peripheries. As such, in the face of the growing number of challenges facing cities globally, we see that urban trees and forests are becoming increasingly central to spatial planning and design practise. And yet, with all this work done on the environmental, ecological, technical and recently also urbanism-related aspects of urban forestry (cf. Journal of Landscape Architecture 1/2023), its site-specific, spatial, aesthetical, and cultural dimensions have received less attention in research. For us as SPOOL editors, this is an invitation to focus on trees and forests from the vantage point of landscape architecture and the related thread of SPOOL, called ‘landscape metropolis’. This thematic thread addresses the dynamic, composite, and layered urban landscape with all its biotic and abiotic elements from a design perspective, with the intent to transcend the conventional city-countryside dichotomy, and to understand landscape as a permanent underlying subtext of the urban condition, with repercussions into the remotest corners of the globe. From a landscape metropolis perspective, cities are understood as complex territorial mosaics where the conventional categories of urban and non-urban give way to a mix of material environments in various stages of ‘naturalness’, or to put it another way: natures in various stages of becoming ‘cultured’. Building on the potentials of an alternative reading of the urban territory then, in this issue we feature a number of select authors who elaborate on this condition, expanding on a designerly frame of knowing and doing in urban forestry. Publication formats also help: besides regular papers, visual essays are featured as a lesser-known yet highly appropriate category of exploration for design research.
