Question 1

The concept of 'carbon sequestration' in landscape design refers to:

Accepted Answer

The capture and long-term storage of atmospheric carbon dioxide by plants and soil

Answer

Carbon sequestration refers to the process by which plants absorb atmospheric carbon dioxide during photosynthesis and store it in biomass and soil organic matter, helping mitigate climate change.

Question 2

Which hydrological parameter is commonly used to estimate stormwater runoff from a landscape site?

Accepted Answer

Runoff Curve Number (CN)

Answer

The Runoff Curve Number (CN), developed by the USDA Natural Resources Conservation Service, estimates stormwater runoff volume based on land cover type, hydrologic soil group, and antecedent moisture conditions.

Question 3

Native plant species are preferred in sustainable landscape design primarily because they:

Accepted Answer

Are adapted to local climate and soils, requiring less water and supporting native wildlife

Answer

Native plants evolved with local climate, soils, insects, and wildlife over millennia, making them better adapted to local conditions, requiring less supplemental water and inputs, and supporting native pollinators and fauna.

Question 4

What does 'life cycle assessment' (LCA) evaluate in sustainable materials selection?

Accepted Answer

The environmental impacts of a material from raw material extraction through end-of-life disposal

Answer

Life cycle assessment (LCA) is a comprehensive analysis of a material's environmental impacts across its entire life cycle, from raw material extraction through manufacturing, transportation, use, and end-of-life disposal.

Question 5

Which of the following best describes 'adaptive management' in sustainable landscape practice?

Accepted Answer

A management approach that incorporates monitoring, evaluation, and strategy adjustment based on observed outcomes

Answer

Adaptive management is an iterative, science-based approach that involves monitoring landscape performance, evaluating outcomes against stated goals, and adjusting management strategies based on what is learned over time.
