Beaver Ecology and Behavior

The video explores the fascinating world of beaver dams, highlighting the world's longest beaver dam in Canada and its significant environmental impact. It delves into the beaver's construction process, site selection, and the impressive speed at which they build. The video also covers the family dynamics of beavers, their territorial expansion, and the ecological benefits their dams provide, such as increased biodiversity and flood control. Overall, beavers are portrayed as vital ecosystem engineers with a profound influence on their surroundings.

What is the approximate length of the world's longest beaver dam?

• 1000 meters

• 500 meters

• 1200 meters

• 850 meters

What type of stream do beavers prefer for building their dams?

• A steep and deep stream

• A rocky stream

• A medium-sized stream with a soft, muddy bottom

• A fast-flowing river

What is the primary material beavers use to construct their dams?

• Vegetation, mud, and sticks

• Plastic

• Metal

• Concrete

How do beavers reinforce areas where water flows the strongest?

• By using mud

• By using large rocks

• By using sand

• By using leaves

What is a key characteristic of beaver dams that helps manage water flow?

• They are built only in winter

• They are always straight

• They allow some water to leak downstream

• They are made entirely of rocks

How long can beavers hold their breath underwater?

• 20 minutes

• 10 minutes

• 5 minutes

• 15 minutes

What happens to young beavers after 2 to 3 years?

• They become predators

• They disperse to find their own territory and mates

• They stay with their parents forever

• They stop building dams

How do beaver dams benefit surrounding wildlife?

• By providing nesting sites and refuges

• By reducing biodiversity

• By increasing predator populations

• By drying up water sources

What is one way beaver ponds help humans?

• By reducing fish populations

• By increasing floodwaters

• By replenishing groundwater stores

• By creating deserts

How do beavers contribute to biodiversity?

• By destroying habitats

• By increasing pollution

• By connecting bodies of water

• By reducing plant growth
