Weird Ways We've Fought Invasive Species

The video discusses the challenges and creative solutions in managing invasive species. It highlights five unique methods: using acetaminophen-laced mice to control brown tree snakes in Guam, employing robots to capture lionfish in the Atlantic, using electrofishing to manage brook trout in the Missouri River, airlifting mountain goats from Olympic National Park, and deploying Judas goats in the Galapagos. These strategies aim to protect native ecosystems from the harmful effects of invasive species.

What is a major challenge in controlling invasive species?

• They are often too small to detect.

• They are protected by law.

• They have no natural predators in new habitats.

• They are beneficial to the ecosystem.

How did the brown tree snake arrive in Guam?

• Through a deliberate introduction.

• By stowing away on a military plane.

• As a pet released by owners.

• Through a natural migration.

What method is used to control the brown tree snake population in Guam?

• Using snake-sniffing dogs.

• Air-dropping poisoned mice.

• Setting up snake traps.

• Introducing natural predators.

Why are lionfish difficult to remove from the ocean?

• They are too small to catch.

• They are beneficial to coral reefs.

• They live in deep waters.

• They are protected by law.

What innovative method is being developed to capture lionfish?

• Using underwater nets.

• Deploying pressure-resistant robots.

• Introducing natural predators.

• Using chemical poisons.

What is the purpose of using Judas goats in the Galapagos?

• To increase goat population.

• To provide food for predators.

• To track and eliminate stragglers.

• To introduce genetic diversity.

Why can't typical approaches be used to control mountain goats in Olympic National Park?

• The goats are protected by law.

• The park is too large.

• Predators would harm native species.

• The goats are too small.
