Ecological Roles and Climate Refuges

The video discusses the impact of climate change on wildlife and ecosystems, highlighting the Upper Columbia River basin as a crucial climate refuge. It emphasizes the importance of water storage and climate stability in the Columbia basin, the role of old-growth forests in biodiversity, and the conservation efforts led by Indigenous communities to protect habitats. The video advocates for maintaining these ecosystems to ensure a thriving environment for both wildlife and humans.

Why do caribou require deep snow in their habitat?

• To keep warm during winter

• To avoid human contact

• To reach lichen for food

• To find shelter from predators

What makes the Upper Columbia River basin a suitable climate refuge?

• Its high population of predators

• Its steep terrain and cold winters

• Its lack of vegetation

• Its proximity to urban areas

What is a key feature of the Upper Columbia that supports its role as a climate refuge?

• Its dry and arid climate

• Its wet forests and large trees

• Its high altitude and thin air

• Its proximity to the ocean

How does the Canadian portion of the Columbia basin contribute to water supply?

• By having a high number of rivers

• By being the largest part of the basin

• By storing and releasing water from glaciers

• By having a large number of lakes

What is a critical ecological role of old-growth forests in B.C.?

• Offering scenic views for tourism

• Sequestering large amounts of carbon

• Providing recreational areas for humans

• Being a source of timber for logging

Why are old-growth forests important for biodiversity?

• They have a high number of hiking trails

• They are easy to access for research

• They are located near urban centers

• They are home to many endangered species

Why is it important to maintain old-growth trees on the landbase?

• To enhance urban development

• To provide more space for agriculture

• To sequester carbon over long periods

• To increase timber production

What is the mission of Y2Y in relation to climate refuges?

• To harvest resources sustainably

• To promote tourism in these regions

• To connect and protect sensitive areas

• To develop urban areas within refuges

How do climate refuges help in carbon management?

• By trapping and storing carbon

• By increasing carbon emissions

• By promoting industrial activities

• By reducing the need for fossil fuels

What role do Indigenous communities play in the Upper Columbia region?

• They manage water resources

• They promote tourism in the area

• They work to protect caribou habitats
