Ben Goldfarb, an award-winning science journalist, discusses road ecology and the impact of roadkill. Topics include wildlife crossings, skunk smells, moose impacts, ocelot facts, how to avoid roadkill, and the ethics of picking up dead animals. Ben's book, "Crossings: How Road Ecology Is Shaping the Future of Our Planet", is also mentioned.
Roadkill poses a significant threat to biodiversity and conservation efforts, highlighting the need for effective solutions like wildlife crossings and reducing speed limits.
Roadkill can elicit strong emotional reactions, causing distress for drivers and serving as a reminder of the dangers of fast driving and the need for safer roads.
Innovative approaches such as wildlife crossings, animal detection systems, and intentional road design have been implemented to prevent roadkill, but further research and implementation are needed.
Deer, large carnivores, and endangered species are particularly vulnerable to roadkill, requiring ongoing mitigation efforts to protect their populations.

The Impact of Roadkill on Wildlife and Humans
Roadkill is a major problem that affects both wildlife and humans. Large carnivores like cougars and bobcats are especially vulnerable to road collisions, as they have large territories and low population densities. It's not just dangerous for animals, but also for humans, with deer collisions causing hundreds of deaths annually. Various solutions have been attempted, including signage, reflectors, and animal detection systems, but many have proven to be ineffective. Other measures like wildlife crossings, elevated highways, and reducing speed limits have shown more promise. Additionally, the reintroduction of natural predators like wolves and cougars can help reduce roadkill rates. Overall, roadkill poses a significant threat to biodiversity and conservation efforts.
The Emotional Impact of Roadkill
Roadkill can evoke strong emotional reactions, both for individuals who have encountered it and for those who have hit animals themselves. Hitting an animal on the road can be distressing and disorienting, often leaving drivers unsure of how to react. People may feel guilt, sadness, or confusion in these situations. The injustice of animals being killed in protected areas such as national parks can be particularly difficult to process. Roadkill also serves as a reminder of the dangers of driving fast and the need for safer roads.
Innovations and Solutions in Roadkill Prevention
Several innovations and solutions have been implemented to prevent roadkill. Wildlife crossings, such as bridges and tunnels, allow animals to safely navigate highways without colliding with vehicles. Animal detection systems, which use sensors and radar, can provide real-time warnings to drivers when animals are present. Some countries have even designed roads with intentional curves and undulations to naturally slow down drivers. While lowering speed limits has been attempted, research suggests that drivers often exceed the posted limits. Other strategies include increased hunting permits to control deer populations and exploring the role of natural predators in reducing roadkill rates. However, roadkill prevention efforts still face challenges and the need for further research and implementation.
Deer and Other Species Most Vulnerable to Roadkill
Deer are among the most vulnerable species to roadkill, with millions of deer dying in collisions with vehicles each year. Large carnivores like cougars, as well as smaller animals like frogs and salamanders during their breeding migrations, also face high risks of being hit by vehicles. The impact of roadkill extends to rarer and endangered species like Florida panthers and ocelots, posing significant threats to their populations. Efforts to reduce deer populations through hunting have shown some potential in minimizing roadkill rates. However, overall, roadkill remains a significant threat to various species and requires ongoing attention and mitigation efforts.
The Benefits of Going to Bed Early
Going to bed early is emphasized as a better alternative to sleeping in. The speaker describes it as a luxury and shares personal experiences of finding joy in going to bed early.
Tips for Avoiding Roadkill
The podcast episode discusses how to avoid hitting animals while driving. Suggestions include staying alert, especially during dusk and dawn, not using phones while driving, and using high beams and horns to signal animals to move.
Cleaning up Roadkill and its Utilization
The episode addresses the question of who is responsible for cleaning up roadkill and what happens to the carcasses. The podcast explains that roadkill is typically either landfilled, incinerated or taken to random dump sites. It also mentions the concept of legalized roadkill consumption in certain states and the efforts to utilize roadkill for food.
Deer in headlights! Alligators in crosswalks! A possum in the oven? If you love wildlife, this is a must-listen to avoid killing critters with your car. Ben Goldfarb wrote the book on road kill and we chat about: wildlife crossings, skunk smells, moose impacts, ocelot facts, what to do if you see roadkill, how to avoid making more of it, and whether it's okay to pick up a dead thing. Ben is an award-winning science journalist with a Masters in Environmental Management from the Yale School of Forestry and Environmental Studies and I’ve waited LITERAL YEARS to talk to him about this topic as he wrote his latest book: “Crossings: How Road Ecology Is Shaping the Future of Our Planet.” Also: flip phones, sleep hygiene, and how to ask your boss for a raise.
