<p>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.</p>Saskia de WitRené van de VeldeLisa Diedrich

https://spool.ac/index.php/spool/article/view/263
<p> </p> <p><span class="Apple-converted-space"> </span>Wildwood Plaza (Robin Winogrond, 2013) reclaims a tiny, residual forest fragment on the city’s edge, transforming it into a recreational space with the power to act as catalyst of the forest imagination. Due to the unique characteristics of forests our imagination has the ability to transform even the most mundane woods into a moving experience. Wildwood Plaza searches to reinterpret these characteristics to become not only rational recreational spaces, but ones in which the immersive, poetic character dominates the experience. The innovation of the project lies in the new interpretation of functional woodland clearings. The design language is one of reduction and simplicity. Not the forest has been designed but its void, the silence of the space has been given character, thus opening up the landscape qualities of the seemingly valueless forest fragment to the urban perception.<span class="Apple-converted-space"> </span></p>Robin Winogrond

https://spool.ac/index.php/spool/article/view/264
<p>Recent sustainability agendas come with the dual mission of responding to climate change and the loss of biodiversity. One strong trend is the increase in the number of trees in urban environments, initiatives often agglomerated under the label of urban forestry. The main focus of this article is to contribute to the development of this discourse by exploring the designerly aspects of urban forestry. This is done by unpacking the concept of ‘urban forestscapes’ as a dynamic and relational concept, derived from a landscape perspective that opens up to spatio-temporal, synthetic, and trans-scalar approaches, and further developed through a process of embedding the research both in relation to literature and <em>in situ</em>. Two wooded areas are studied at the Alnarp campus of the Swedish University of Agricultural Sciences (SLU), in the Malmö- Copenhagen conurbation. The campus holds the first landscape laboratory in Scandinavia, a real-world experimentation site dedicated to the study of urban forestry and woods. The article suggests a recognition of the interpretative openness of the concept in addition to its hybrid qualities with the synthesizing power of overcoming divisions like that of nature/culture or forest/city. The results include insights into experiential characteristics of urban forestscapes as well as methodological considerations.</p>Caroline DahlDennis Andreasson

https://spool.ac/index.php/spool/article/view/265
<p>The paper explores the implementation of the afforestation programme in Flanders since 2019. Framed by the authors’ situated knowledge, it recounts the diverse strategies and tools of the programme, aimed at realising 4,000 hectares of new forests by 2024. With a focus on collective and systemic efforts, the paper outlines three operational domains to analyse the coalition-building process at regional and local levels: setting the institutional space, infrastructuring afforestation in spatial practice, and tailoring design tools for urban forestscapes. It explains how, beginning with the creation of the regional Forest Alliance coalition, a set of policies, soft power mechanisms, and designs have been promoted to accelerate the realisation of (sub)urban forest projects. In doing so, the article proposes a discussion on the forest metropolis as a contextualised cultural project, capable of aligning forest policies with urban forestry initiatives, as well as converging the urbanisms of territorial and domestic spheres, and positioning designers as crucial interfaces between these diverse realms.</p>Liesl VanautgaerdenFederico Gobbato Liva

https://spool.ac/index.php/spool/article/view/266
<p>If the ambition of the Flemish territory is to become more forested, then an approximation is needed between forest and urbanization processes. Forest expansion can only be realized by developing a new understanding between forest and urbanization. This article discusses urban design explorations that stimulate a spatial transformation grafted on the forest as a structuring element of the Western Witness Hills of Leuven, through the ‘forest figure’. The forest figure is explored as a concept able to incorporate and mould urban and forest ambitions into a workable spatial frame.</p>Wim WambecqBruno De Meulder

https://spool.ac/index.php/spool/article/view/267
<p>This visual essay outlines how Ruderal, a studio based in Tbilisi, Georgia, has developed new approaches to urban forestry applicable to the legacy of Soviet-era forests. The collapse of the Georgian Soviet Socialist Republic and the resulting rapid privatization led to the reduction and degradation of Tbilisi’s public spaces. Ruderal’s approach to urban forestry is presented in three projects: the Mtatsminda Pilot Project (including Narikala Ridge), the Betania House Forest Garden, and the Arsenal Oasis Project. The projects illustrate how a new practice of urban forestry has grown from the limitations and opportunities of Tbilisi’s urban context. Ruderal’s practice pursues interventions at multiple scales along the following forestry principles: 1) grafting into baseline conditions; 2) utilising and expanding the ‘fertile section’; 3) incorporating genetic diversity and species competition.</p>Sarah CowlesBenjamin Hackenberger

https://spool.ac/index.php/spool/article/view/268
<p>Urbanization presents profound challenges to environmental sustainability, characterized by the depletion of green spaces and the degradation of urban ecosystems. Acknowledging the pivotal role of urban forests in mitigating environmental degradation and enhancing urban life quality, cities are increasingly adopting participatory approaches to afforestation. This paper explores the relationship between research and the practical implementation of urban forests, emphasizing the significance of constructing a robust network of stakeholders.</p> <p>The case study selected is the research project called Forestami, which aims to plant three million new trees and shrubs within the metropolitan area of Milan by 2030. This initiative promotes green infrastructure, ecological connections, and related ecosystem services; improves the public health of citizens; increases urban and peri-urban permeable surfaces; and protects and expands territorial biodiversity. By examining the interplay between research insights and on-the-ground implementation, this paper underscores the critical importance of forging a diverse network of stakeholders to navigate the complexities of urban forestry initiatives. Through this collaborative framework, cities can cultivate resilient and vibrant urban ecosystems that enrich the lives of residents while safeguarding the environment for future generations.</p>Maria Chiara Pastore

https://spool.ac/index.php/spool/article/view/269
<p>By contrasting three ongoing research projects along with complementary arguments, this paper explores mediating practices from environmental art and architecture perspectives in the context of industrial forestry and Sweden’s ‘green transition’. The general discourse on ‘green transitions’ significantly amplifies the cultural and economic values of forests within and beyond Sweden. This amplification turns forests into reflexive entities that compel broader value revisions, challenging the extractivist character of modern urbanism. An example is the recent public debate in Sweden about what distinguishes a ‘forest’ (skog) from a ‘plantation’ (plantage). The debate does not reinforce the binary divide between the terms. Instead, it is prompting renewed, if overdue, attention to suppressed Indigenous and rural ancestries, as well as to alternative narratives and techniques that rethink industrial forestry tropes. From that context, our arguments position our respective research works—regarding 1) tree nurseries and climate injustice, 2) the transnational timber industry, and 3) new resource economies for the built environment—in ways which form and encourage research intersections that recognize ancestral, physical, and temporal scales as a potential for enriching the model that is the Swedish ‘green transition’.</p>Luis Berríos-NegrónCornelia RedekerToms Kokins

https://spool.ac/index.php/spool/article/view/271
<p>This essay reports on a ‘living lab’ approach to develop a new understanding of below- and above-ground ecological processes as the foundation for robust urban forest habitats. This experimental approach includes a series of design and implementation projects in the city of The Hague, the Netherlands. In contrast to mainstream greening projects led by local governments, these experiments enable urban trees to form more robust forest-like systems by creating a symbiosis between soil (organisms), trees, plant communities, and species. As implemented reference projects are limited, a learning-by-doing methodology was adopted. A transdisciplinary team, consisting of landscape architects/designers, arborists, botanists, municipal and private green space maintenance organizations, has initiated, implemented, and monitored a series of pilot projects. Analysis of ten natural reference locations in the surrounding countryside has helped to define natural and forest-like soil conditions and plant communities for the three living lab locations in the city. Local residents have been engaged in the design, implementation and maintenance process. Sharing insights so far contributes to the transition of reconnecting soil, nature, and people in cities.</p>Jean-François GauthierWiebke KlemmCecil C.

https://spool.ac/index.php/spool/article/view/272
<p>This paper expands on the term ‘urban forest’ through spatial historical research and via the concept of Forestscape. The city of Delft in the western part of the Netherlands is taken as a case study, with the sixteenth, seventeenth, and eighteenth centuries as the sample period. Based on a methodology examining the spatial history of Delft from both a processes and a patterns perspective, we identify six tree planting practices or ‘afforestation events’. These plantings were integral to the early modern cityscape to the extent that the spaces in which they were planted were typologically incomplete without them. We identify tree plantings in group, line, and volume arrangements and posit these arrangements as a foundational scale in a multi-scalar understanding of the urban forest. The term ‘plantation’ formed the leitmotif for these plantings, interpreting natural features such as copses, groves, woods, and forests. The case study also demonstrates how, even in the early modern period, tree arrangements were established for a variety of benefits which ostensibly resonate with the contemporary notion of ‘ecosystem services’, but that were instead part of an alternative sensibility of what ‘city’ and ‘nature’ is. In this frame, the term Forestscape offers a way forward to retroactively interpret the historic urban forest and counter the current binary city-versus-nature discourse. We find that the collection of tree arrangements established in Delft in the period 1500–1800 presents a ‘wooded watermark’ of the city, which in many instances was reanimated with new tree plantings, demonstrating how parts of an urban forest can become a fixture in the morphology of the city and the lives of its citizens. At the regional scale, the extent of tree plantings around Delft with urban ‘roots’ extends far into the urban hinterland, while at the same time, trees and wooded areas with rural ‘roots’ extend well into the urban area. This condition opens a discussion on the inter-relationship between urban and rural realms and challenges the simplistic division between these two worlds apparent in contemporary spatial planning and design.</p>Erik de JongRené van de Velde
