• How to Conserve Wildlife Migrations in the American West (2022). The natural spectacle of wildlife migration has beguiled people for millennia—a sense of wonder that continues today. Aristotle and his contemporaries marveled at the sudden disappearance of birds and animals in the fall and their reappearance in spring. Now, in the 21st century, science is uncovering fascinating new information about the amazing treks that mule deer, elk, and pronghorn make each year across the American West.

  • Demystifying Wildlife Crossing Infrastructure Projects Webinar Series (2022). This webinar series, co-hosted by ARC Solutions, Center for Large Landscape Conservation, National Parks Conservation Association, and Wildlands Network, provides information on the value of wildlife crossings, how strong data and partnerships underlie project success, and relevant federal infrastructure funding opportunities available.

  • Innovative Strategies to Reduce the Costs of Effective Wildlife Overpasses (2021). This report compiles design and construction techniques, strategies and considerations aimed at reducing costs, while maintaining or improving the overall efficacy of wildlife overpasses. Examples range from recognition that good design requirements (such as design life, structural loading, and clearance box dimensions) can significantly affect project costs, to acknowledgment that settlement restrictions used for vehicular bridges may not apply to wildlife crossing structures, to recognition that the use of materials such as geosynthetic reinforcing systems and expanded polystyrene blocks for fill can potentially reduce costs.

  • Highway Crossing Structures for Wildlife: Opportunities for Improving Driver and Animal Safety (2021). Developed collaboratively by a team of engineers, ecologists, biologists, landscape architects, and policy experts, this report summarizes the challenges and anticipated benefits of making a national commitment to a systematic network of wildlife crossing structures to increase driver and animal safety.

  • Land Trusts and Wildlife Crossing Structures (2023). This toolkit details how land trusts can contribute to highway infrastructure projects for wildlife. It serves as a resource to help land trusts start to or further engage in wildlife crossing structure projects by capturing lessons learned and best practices. 

  • A Toolkit for Developing Effective Projects Under the Federal Wildlife Crossings Pilot Program. This resource provides best practices, examples, and resources for designing effective wildlife crossing projects in accordance with each of the grant application criteria of the Wildlife Crossings Pilot Program.
