Ecological Restoration Concepts and Challenges

The video discusses ecological restoration, a process aiding the recovery of damaged ecosystems. It highlights the challenges posed by development and invasive species, emphasizing the importance of restoration for both ecosystems and human communities. Techniques such as removing invasive species and planting native seeds are explored, with examples from The Morton Arboretum and Somme Prairie Grove. The video concludes with a call to action for public involvement in restoration efforts.

What is the primary goal of ecological restoration?

• To develop urban areas

• To eliminate all invasive species

• To assist in the recovery of damaged ecosystems

• To create new ecosystems

What is a significant threat to prairies in Illinois?

• Lack of sunlight

• Invasive species and development

• Excessive rainfall

• Overpopulation of native species

What is the impact of invasive species on native ecosystems?

• They out-compete native species

• They improve soil quality

• They have no impact

• They enhance biodiversity

How do healthy ecosystems benefit stormwater management?

• They increase flooding

• They absorb and manage more stormwater

• They redirect stormwater to urban areas

• They have no impact on stormwater

What is a benefit of trees in ecological restoration?

• They reduce biodiversity

• They block sunlight

• They increase air pollution

• They clean the air we breathe

What is one of the first steps in ecological restoration?

• Increasing human population

• Introducing new animal species

• Removing invasive species

• Building new structures

What is the significance of spacing in oak tree restoration?

• It helps in the growth of other tree species

• It allows for better sunlight exposure

• It supports the next generation of oak trees

• It prevents soil erosion

Where is ecological restoration taking place?

• Only in protected national parks

• Only in large wilderness areas

• In urban centers only

• In both wilderness and local communities

What was a key achievement at Somme Prairie Grove?

• Doubling the number of plant species

• Conversion into a recreational park

• Introduction of new animal species

• Complete removal of all invasive species

Why is community involvement crucial in ecological restoration?

• It helps control invasive species and reintroduce native ones

• It speeds up urban development

• It increases tourism

• It reduces the cost of restoration
