Specifically, the Managed Forest Tax Incentive Program (MFTIP) and its corresponding Managed Forest Plan are investigated as a means through which a diversified field of knowledge has been activated to enable climate-conscious adaptive stewardship across the region. This case study uses a qualitative approach, incorporating document analysis, semi-structured interviews, and direct observation. Similar patterns and relationships within and across sites are identified to build theory and shed light on the socio-ecological context of private forest management. Set within southern Ontario’s history of forest management and the rise of neoliberal environmental governance, this paper contributes theoretically to scholarship on state legibility. The results illustrate a shift in stewardship on private lands through a rescaling of management responsibility that embraces different perspectives and builds place-based practical knowledge of forest systems. By mapping and building knowledge networks, diverse approaches to management have proliferated at the local and regional levels. These approaches have been influenced by previous management experience, different professional backgrounds, knowledge of participants, and the motivation of landowners to engage in active stewardship. The process of developing a management plan plays a key role in making landscapes legible to all stakeholders. The document also serves as an instrument of the state to build private landowners’ and forest consultants’ knowledge and capacity. This has set in motion a socio-ecological landscape strategy to address encroachment, invasive species, and climatic challenges in this increasingly urbanizing region.","PeriodicalId":373407,"journal":{"name":"Arboriculture & Urban Forestry","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139314213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We spatially modelled 4 planting scenarios for increasing tree canopy cover by 2050 in a densifying neighbourhood in Vancouver, Canada, with low (< 10%) existing tree canopy. Based on mortality assumptions, we aged out and replaced 1,853 to 2,445 trees since 2020. We added 6,079 to 11,726 trees across the 4 scenarios (10,228 to 15,823 total), increasing canopy cover from 7% in 2020 to a maximum of 16% by 2050. Despite rigorous tree planting, we were unable to achieve a 30% canopy cover target at neighbourhood scale. Tree replacement due to mortality was a major contributor to decreased canopy cover and volume in future scenarios. The 31% to 34% reduction in future canopy cover due to the replacement of aged-out trees was driven by changes on private parcels. Our systematic framework for generating and spatially modelling trees in a simulated future neighbourhood provides an opportunity for iteratively assessing multiple potential tree planting configurations. Future work for this project includes investigating social-ecological, outdoor shading, and building energy implications of various modelled urban forest strategies.","PeriodicalId":373407,"journal":{"name":"Arboriculture &amp; Urban Forestry","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139314402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
