Wildlife Crossings and Their Impact

The video discusses the challenges and solutions related to animal-vehicle collisions on highways. It highlights the economic and ecological impacts of these collisions and explores the effectiveness of wildlife crossings, such as those in Banff National Park, in reducing accidents and restoring habitats. The video also addresses the cost challenges of implementing these structures and presents innovative solutions from the ARC competition. The need for more wildlife crossings is emphasized, especially as climate change alters animal movement patterns.

What is one proposed solution to reduce animal-vehicle collisions on highways?

• Installing speed bumps

• Building wildlife crossings

• Widening roads

• Increasing road signs

What is the estimated annual cost of wildlife vehicle collisions in the US?

• $10 billion

• $1 billion

• $5 billion

• $8 billion

How do roads negatively impact wildlife besides causing collisions?

• They cause noise pollution

• They divide wildlife populations

• They increase air pollution

• They lead to deforestation

What was the effect of wildlife crossings in Banff National Park on elk-vehicle collisions?

• Reduced to less than a half dozen per year

• Decreased by 50%

• Increased by 50%

• No change

Which species was recorded crossing the wildlife structures 66 times in one summer in Banff?

• Deer

• Lynx

• Elk

• Grizzly bear

What is a major factor limiting the construction of wildlife crossings?

• Lack of public interest

• Technological limitations

• High initial costs

• Environmental concerns

What was the purpose of the ARC design competition?

• To create more aesthetically pleasing crossings

• To develop cost-effective and sustainable wildlife crossing designs

• To increase public awareness about wildlife

• To improve road safety for humans

What was a key feature of the winning ARC design?

• It was made entirely of recycled materials

• It was designed for human use as well

• It eliminated the need for pillars on the highway

• It was the largest overpass ever built

Why might the need for wildlife crossings increase in the future?

• Because of declining animal populations

• As a result of more road construction

• Because of climate change affecting animal movement

• Due to increased urbanization

What does Nina-Marie Lister hope planners will do in the future?

• Focus on building more roads

• Return to ARC designs for wildlife crossings

• Prioritize human safety over wildlife

• Reduce funding for wildlife projects
