This report is a collaboration between landscape designers, policy strategists, and species biologists from HKU, Smithsonian, WWF, FFI, and WCS. The importance of the study is that it takes abstract regional models from conservation biology developed over the past decade and applies them to site-specific conditions for the design of wildlife crossings where data is extremely limited. A set of principles was developed to reduce the abstraction and potential error in regional models of animal movement rate (proxied by electric circuit theory) and is potentially a breakthrough in multi-species modeling using these techniques, still critiqued as impractical only a year ago. The entire process is automated and outputs an optimized set of potential wildlife crossings as segments, rather than points, to allow flexibility in decision-making during road design and alignment due to costing and local landscape conditions.
