This podcast series is part of the AASHTO Environmental Management technical service program operated by the American Association of State Highway and Transportation Officials. It explores a wide array of environmental topics that affect state departments of transportation and the infrastructure programs they oversee.
During this podcast episode, 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 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 – offering insights on the importance of quality data collection, advocacy, and conversation when working with big stakes.
