Salmon and Steelhead Conservation Issues

The video discusses the decline of salmon and steelhead in the Pacific Northwest and highlights the importance of riparian zones in reversing this trend. Riparian zones, which are areas adjacent to rivers, play a crucial role in maintaining water quality and providing habitat for young fish. Vegetation in these zones offers shade, food, and stability to riverbanks, preventing erosion and pollution. The video emphasizes the need to protect and restore these areas to ensure the survival of salmon and steelhead for future generations.

What is the main concern regarding salmon and steelhead in the Pacific Northwest?

• Increased water temperature

• Decline in population

• Lack of food sources

• Overfishing

How do riparian zones contribute to water quality?

• By increasing water temperature

• By providing a habitat for predators

• By filtering pollutants and chemicals

• By blocking sunlight

What role do fallen trees in riparian zones play for fish?

• They block fish migration

• They provide food for fish

• They increase water flow speed

• They create hiding and resting places

Why is vegetation important in riparian zones?

• It increases soil erosion

• It blocks fish from entering the river

• It attracts predators

• It stabilizes riverbanks

What is a major reason for the decline in salmon and steelhead populations?

• Introduction of invasive species

• Climate change

• Neglect of riparian zones

• Overfishing

How wide should a riparian zone generally be?

• As wide as the height of the tallest tree

• As wide as the length of a fish

• As wide as the river

• As wide as the river is deep

What is the primary benefit of protecting riparian zones?

• Reducing water levels

• Increasing tourism

• Promoting urban development

• Enhancing fish habitats

What can individuals do to help protect salmon and steelhead populations?

• Support urban development

• Plant non-native species

• Participate in restoring riparian zones

• Increase fishing activities
