Functional Habitat Connectivity Analysis for the Township of Langley, British Columbia

Listed in Borealis

In response to the growing concern of loss of biodiversity due to global urbanization, much research has investigated its influence on habitat connectivity, yet little is known about the functional habitat connectivity of the Coastal Douglas-fir (CDF) and the Western Hemlock (CWH) BEC Zone in urban areas.

Description

This study aimed to assess the functional habitat connectivity of the Township of Langley in British Columbia, Canada, to facilitate urban planning and urban biodiversity conservation.

Using lidar-derived and land cover data, quantified habitat connectivity was quantified with the probability of connectivity index (PC) for three species (the western red-backed salamander, the American red squirrel, and the brown creeper) with different habitat requirements and mobility. Suitable habitat patches were filtered and selected based on the habitat requirements of each species, and habitat networks were generated considering dispersal distance to model the connectivity index in the Conefor software.

Key patches, hub patches, and key-hub patches were identified based on the patch importance level generated from Conefor. The study found a large variance in PC and distribution of important patches among species in the landscape. The major connectivity corridor, identified according to the distribution of key-hub patches for all species, showed some important areas for overall connectivity improvement.

Despite limitations on timeliness, computational power and consideration of dispersal barriers, this study enhances understanding of local-scale connectivity and offers guidance for urban planners and developers seeking to incorporate biodiversity conservation in decision-making. Identification of key patches, hub patches, and key-hub patches also highlights potential areas for habitat preservation, which is particularly relevant for urban green infrastructure design that supports both human well-being and biodiversity conservation.
