In this episode, Dan Medeiros joins the Stream by AASHTO to discuss his work with the Conservation Fund – a 40-year-old firm that purchases land across the U.S. to preserve wildlife habitat – and its efforts in California to support the safety and growth of mountain lion populations and their habitats. Medeiros discusses how mountain lion conservation efforts interconnect with transportation infrastructure needs; especially how large barriers and quick-moving cars are two of the main culprits behind mountain lion deaths. He also points to specific examples, including the death of “54M” – a mountain lion tracked by that the Conservation Fund that was tragically killed by a vehicle when trying to cross a major highway.Medeiros also explains the importance of stakeholder input on large infrastructure projects that involve mountain lion populations, including state departments of transportation, local residents, and private organizations. He provides input on the importance of quality data collection, advocacy, and conversation when working with big stakes.This podcast series is part of the AASHTO Environmental Management technical service program operated by the American Association of State Highway and Transportation Officials.
