“…Large-scale projects, like street-tree planting in new subdivision developments, often acquire trees from regional wholesalers instead of local nurseries [29]. At a given time, species selection may be limited due to location, resources, or customer demand; some tree species requested by the developer or urban forester may be substituted or outsourced, potentially resulting in more unfavourable species choices and reducing diversity enhancements [30].…”

Is (sub)urban forest diversity shaped by previous land use? This study was designed to quantitatively assess the impacts of subdivision development on urban tree-species composition in two Canadian cities: Halifax, Nova Scotia, and London, Ontario. The main goal was to determine whether cities with contrasting pre-urbanized or pre-settlement landscapes-woodlands in Halifax and agricultural fields in London-also revealed differences in urban tree diversity losses and/or gains due to urbanization. In each city, four residential neighbourhoods representing two age categories, older and newer (40-50 years, <15 years), were examined and trees on three land types were sampled: public (street), private (residential), and remnant (woodland). All public street trees within the chosen neighbourhoods were inventoried and approximately 10% of the residential property lots were sampled randomly. Plots were examined in remnant forests in or near each city, representing the original forest habitats prior to agricultural and/or urban landscape transformations. Diameter at breast height, species richness and evenness, and proportions of native and non-native trees were measured. In both cities, streetscapes in newer neighbourhoods exhibit greater species richness and evenness, and are characterized by substantially more native trees. Despite this trend, developers and home owners continue to intensively plant non-native species on newer and smaller property lots. Older neighbourhoods in Halifax containing remnant forest stands hold the greatest number of native trees on private property, alluding to the importance of residual forest buffers and patches in promoting naturalness in the private urban forest. These results suggest that identifying and quantifying flows of species between green spaces during and after development is valuable in order to effectively promote native species establishment and enhance overall urban forest diversity.

“…Tree selection in urban areas is based on several practical criteria (e.g., appearance, seed or pollen production, available space, soil conditions, native species) that differ among the various stakeholders (architects, managers, foresters, citizens, and nursery operators) (Conway and Vander Vecht 2015). Nevertheless, in spite of these differences, one may observe great redundancy in the species/varieties chosen for planting (Bourne and Conway 2014).…”

“…Still, the native character of a species does not guarantee these benefits as tree species distributions often encompass large territories. For example, in a recent study, professionals in the City of Toronto's urban forestry unit mention that they do not have the means to verify that the trees they bought come from the right climatic zones (Conway and Vander Vecht 2015). They explain that if local nurseries cannot meet the demand, plants are sometimes procured from U.S. nurseries located farther south which provide plants that are ill-adapted to northern climatic conditions.…”

“…At present, the needs of cities when selecting trees to fulfil their management plans do not necessarily match the nurseries' available stocks (Sydnor et al 2010). It is also worth mentioning that nursery stock management is based on client demand, while client choice will also depend on the species available in nurseries (Conway and Vander Vecht 2015). These dynamics, which are not conducive to stock diversification, should be broken by nursery involvement in projects related to the origin or taxonomic identification of trees for urban forestry.…”

Consumers, retailers, investors, and governments want quality products that are both safe and obtained through legal and sustainable practices. The solution put into place to meet those challenges requires the implementation of a traceability system. In the context of forestry, traceability is the ability to inform about the identity or provenance of a wood product. The principle of traceability helps establish trust among the various stakeholders throughout the value chain. To this day, most traceability systems are based on paper permits, which are easier to falsify than systems that are based on genetic markers. In this manuscript, we define the elements of a traceability system based on genomic tools that could be useful for the Canadian forest sector. We also present several examples in which genomic tools are or could be used as traceability systems. Genomic tools and data happen to be available in quantity for several forest species and they could constitute the basis for the development of such traceability systems. Our aim is to demonstrate that there are actually great opportunities to develop such systems that could be applied to the Canadian forest sector.Keywords: traceability, genomic, markets, certification, sustainability, urban forestry, quality control, value chain, taxonomy, origin, database RÉSUMÉ:Les consommateurs, les détaillants, les investisseurs et les gouvernements veulent des produits de qualité, sécuritaires et qui résultent de pratiques légales et durables. Les principes de la traçabilité permettent de répondre à ces différents enjeux. Dans le contexte forestier, la traçabilité est la capacité d'informer sur l'identité ou la provenance d'un produit du bois. Ce principe aide à établir la confiance entre les différents acteurs de la chaîne de valeur. À ce jour, la plupart des systèmes de traçabilité sont basés sur des permis en papier qui sont facilement falsifiables. Dans ce manuscrit, nous définissons les élé-ments d'un système de traçabilité basé sur des outils génomiques qui pourrait être utile pour le secteur forestier canadien. Nous présentons aussi plusieurs exemples de la façon dont les outils de la génomique sont ou pourraient être utilisés. Des données et des outils génomiques sont actuellement disponibles en grandes quantités pour plusieurs essences forestières et ceux-ci pourraient constituer la base du développement de tels systèmes de traçabilité. Notre objectif est de démontrer qu'il y a actuellement de grandes opportunités pour développer de tels systèmes qui pourraient s'appliquer au secteur forestier canadien.

“…For landscape plants, the concept of adaptability has been recognized by landscape architects, planners, and horticulturists. Factors of regional climate, soil conditions, sunlight, and pollution have been discussed in studies of plant adaptability [3,[65][66][67][68]. However, these studies were mainly focused on qualitative methods.…”

Sunshine is an important factor which limits the choice of urban plant species, especially in environments with high-density buildings. In practice, plant selection and configuration is a key step of landscape architecture, which has relied on an experience-based qualitative approach. However, the rationality and efficiency of this need to be improved. To maintain the diversity of plant species and to ensure their ecological adaptability (solar radiation) in the context of sustainable development, we developed the Urban Plants Decision Support System (UP-DSS) for assisting plant selection in urban areas with diversified solar radiation. Our methodology mainly consists of the solar radiation model and calibration, the urban plant database, and information retrieval model. The structure of UP-DSS is also presented at the end of the methodology section, which is based on the platform of Geographic Information Systems (GIS) and Microsoft Excel. An application of UP-DSS is demonstrated in a residential area of Wuhan, China. The results show that UP-DSS can provide a very scientific and stable tool for the adaptive planning of shade-tolerant plants and photoperiod-sensitive plants, meanwhile, it also provides a specific plant species and the appropriate types of plant community for user decision-making according to different sunshine radiation conditions and the designer's preferences.
