Ecological Concepts and Restoration Techniques

The video discusses the challenges of degraded landscapes, highlighting issues like poverty, extinction, and desertification. It emphasizes nature's resilience and the potential for ecosystems to recover with minimal intervention. Key metrics for ecosystem health include biomass, necromass, and biodiversity. The video explains ecological succession, from bare ground to climax communities, and introduces novel ecosystems. Techniques for restoration, such as soil stabilization and seed balls, are explored, with a focus on stimulating natural processes to aid recovery.

What are some of the major global issues caused by degraded landscapes?

• Technological advancements

• Increased rainfall and flooding

• Human poverty and species extinction

• Urbanization and industrial growth

Which of the following is NOT a metric of a healthy ecosystem?

• Biomass

• Biodiversity

• Temperature

• Necromass

What is the role of pioneer species in ecological succession?

• They prevent other species from growing

• They are the final stage of succession

• They stabilize the soil and start the Web of Life

• They increase soil erosion

What is a climax community in the context of ecological succession?

• A newly formed ecosystem

• A community dominated by annual weeds

• A stable ecosystem that has reached its peak complexity

• A community that is constantly changing

What are novel ecosystems?

• Ecosystems that are in the early stages of succession

• Ecosystems that are entirely natural

• Communities of species assembled by human impact

• Ecosystems that have never been impacted by humans

What is the significance of biomass, necromass, and biodiversity in ecosystem health?

• They are only important in urban areas

• They only apply to aquatic ecosystems

• They are indicators of ecosystem health

• They are unrelated to ecosystem health

What is the main challenge in predicting the outcome of ecological succession?

• The constant need for human intervention

• The uniformity of ecosystems

• The unpredictability of species interactions

• The lack of available seeds

What is the purpose of using seed balls in ecosystem restoration?

• To create artificial ecosystems

• To increase soil erosion

• To prevent seed germination

• To distribute seeds over large areas without direct intervention

How do seed balls protect seeds until they are ready to germinate?

• By exposing them to sunlight

• By encasing them in clay and manure

• By keeping them dry

• By burying them deep underground

What is the role of drones in modern ecosystem restoration?

• To monitor wildlife

• To plant trees manually

• To distribute seed balls over large areas

• To remove invasive species
