Ecosystem Restoration and Conservation Concepts

What was the primary environmental issue caused by the 1908 flood near the Milltown Dam?

• A massive increase in fish populations.

• The dam breaking and destroying towns.

• The spread of toxic mining waste into the river.

• A severe drought that dried up the river.

Which field focuses on restoring ecosystems that have been damaged?

• Conservation Biology

• Restoration Ecology

• Environmental Science

• Zoology

What is the key factor that helps hold an ecosystem together and allows it to function properly?

• The amount of rainfall

• The presence of large predators

• The level of biodiversity

• The average temperature

Why is genetic diversity important for a species' survival?

• It makes individuals within the species look identical.

• It helps the species to evolve and adapt to new challenges.

• It ensures all individuals have the same traits.

• It prevents any changes in the species over time.

What is the term for the smallest population size at which a species can survive and sustain itself?

• Maximum Carrying Capacity

• Minimum Viable Population

• Optimal Breeding Size

• Extinction Threshold

Which of the following is NOT a step involved in declining population conservation?

• Determining if the population is actually declining.

• Figuring out the historical size and requirements of the population.

• Identifying the root cause of the population's decline.

• Introducing a new invasive species to control the decline.

What type of restoration involves removing human-made impacts and rebuilding natural structures like river channels and vegetation?

• Bioremediation

• Biological Augmentation

• Structural Restoration

• Ecological Succession

Which restoration strategy involves adding organisms to an ecosystem to restore missing materials, such as using nitrogen-fixing plants in damaged soil?

• Structural Restoration

• Bioremediation

• Biological Augmentation

• Declining Population Conservation
