Wild Paths and Green Infrastructure in City Plans: Reimagining Urban Space to Support Species Connectivity

Rapid urban expansion across southwestern Florida has led to extensive habitat fragmentation and degradation, presenting significant ecological challenges for the persistence of multiple species, including the Big Cypress fox squirrel (Sciurus niger avicennia; BCFS), a state threatened and imperiled subspecies endemic to the Big Cypress Basin. This study uses high-resolution ecological modeling, Omniscape, to assess the functional connectivity of BCFS habitat within the urbanizing landscape of Fort Myers, Florida, and a green infrastructure (GI) transect-based approach to identify strategies for improving habitat and connectivity within the urban landscape. Results demonstrate that BCFS movement is disproportionately represented in high-density urban zones, with priority bottleneck patterns emerging in surrounding lower-density, transitional land use areas such as suburban neighborhoods and golf courses. By combining spatial modeling and applied GI design, this study offers a replicable framework for embedding species conservation into local and regional planning processes. Given the model-based and species-specific scope of this study, future research should focus on empirical validation and extending this framework across multiple species and scales. Overall, the findings emphasize the importance of multiscalar, landscape-sensitive planning strategies to mitigate anthropogenic fragmentation, enhance ecological resilience, and support the long-term persistence of native species in rapidly developing regions.
