Providing safe passage for urban wildlife
This guidebook, Achieving Landscape Permeability in an Urban Environment: Wildlife Crossings, providing safe passage for urban wildlife, provides recommendations to enhance the design and effectiveness of transportation planning processes within the context of evolving and complex scientific information and research.
