Grizzly Bears and Conservation Efforts

What was the primary reason for the decline in grizzly bear populations between 1850 and 1920?

• Disease

• Climate change

• Habitat destruction

• Hunting

Why are grizzly bears considered an 'umbrella species'?

• They have a unique diet that supports biodiversity.

• Their presence indicates a healthy ecosystem supporting various species.

• They are the only species that can survive in diverse habitats.

• They are the largest carnivores in North America.

What is the main goal of the Yellowstone to Yukon Conservation Initiative?

• To reconnect fragmented grizzly populations and restore habitats.

• To relocate grizzly bears to urban areas.

• To create a new national park for grizzly bears.

• To increase the number of grizzly bears in zoos.

What is a significant challenge faced by grizzly populations due to human activities?

• Decreased genetic diversity

• Fragmentation of populations

• More natural habitats

• Increased food supply

How do wildlife corridors help grizzly bears?

• They provide food and water.

• They allow safe movement and genetic exchange.

• They reduce the need for migration.

• They offer shelter from predators.

What is a potential consequence of not restoring wildlife corridors for grizzly bears?

• Increased population size

• More interaction with humans

• Greater genetic diversity

• Smaller, isolated populations

How does climate change impact grizzly bear habitats?

• It creates more food sources.

• It stabilizes weather patterns.

• It forces bears to move in search of favorable climates.

• It reduces the need for migration.

What role do individuals play in supporting conservation efforts?

• Individuals should avoid all natural areas to protect wildlife.

• Conservation is solely the responsibility of government agencies.

• Individuals can participate in activities like planting trees and counting wildlife.

• Only scientists can contribute to conservation.

What is one method used to monitor grizzly bear populations?

• Satellite tracking

• Hair snagging for genetic analysis

• Counting footprints

• Tagging with GPS collars

What is the significance of the latest studies on grizzly bear populations?

• They show a decrease in grizzly bear numbers.

• They indicate that grizzly populations are more connected than in the past 100 years.

• They reveal that grizzly bears are moving away from their natural habitats.

• They suggest that grizzly bears are no longer endangered.
