In the process of urbanization, inadequate prioritization of biodiversity areas has resulted in habitat fragmentation, subsequent species extinctions, and as a consequence, a decline in ecosystem services over time. Although initiatives like the Vancouver Plan (2022) propose a 100-year ecological vision to reintroduce ecological networks and ensure ecological connectivity, their implementation encounters challenges due to the city's high land-use intensity. Thus, this study aims to configure an optimal ecological network that accommodates the current and future land use patterns of Vancouver city. Utilizing linkage mapping analysis, the research defines a city-wide ecological network, creating corridors between biodiversity hotspots. Zooming into identified corridors Circuit theory and the biodiversity-sensitive urban design approach are employed, proposing a landscape design configuration process. The analysis reveals a significant ecological gap in the Vancouver city matrix, characterized by high land-use intensity and habitat isolation. In prioritizing linkages with the highest restoration impact, the research proposes a set of design implications to function as a toolkit for enhancing wildlife movement, introducing habitats, and promoting positive human–nature interactions. In summary, this study provides a systematic approach to establishing an optimal ecological network in Vancouver's urban context, integrating city planning policies. To enhance the performance of ecological corridors, the study recommendations include increasing vegetation cover in ecological gaps, the establishment of new core areas, and the integration of the green infrastructure network as alternative wildlife corridors. The importance of a validated design toolkit tailored for various ecological priority areas is emphasized as a vital requirement in guiding efforts for ecosystem restoration and ensuring regional ecological security.
