Sustainable Landscaping Flashcards

What is 'carbon sequestration' in the context of landscape design?

Answer: The process by which plants and soils capture and store atmospheric CO₂, contributing to climate change mitigation

Carbon sequestration in landscapes refers to the capture and long-term storage of atmospheric carbon dioxide in plant biomass and soil organic matter, helping offset greenhouse gas emissions.

Which US federal program provides guidance and incentives for native plant use and wildlife habitat in residential landscapes?

Answer: National Wildlife Federation (NWF) Certified Wildlife Habitat program

The NWF Certified Wildlife Habitat program encourages homeowners to create landscapes with native plants, food sources, water, and shelter that support wildlife and biodiversity.

What is 'dark sky' compliant landscape lighting?

Answer: Outdoor lighting that is fully shielded, directed downward, and uses warm-color LEDs to minimize light pollution and protect nocturnal ecosystems

Dark sky compliant lighting uses fully shielded, downward-directed fixtures with warm-color LEDs (2700K or lower) to minimize sky glow and light trespass, protecting nocturnal wildlife and night visibility.

What does 'right plant, right place' mean in sustainable landscape design?

Answer: Selecting plants whose natural requirements (sun, soil, water) match existing site conditions, reducing the need for amendments and irrigation

Right plant, right place means selecting plants whose inherent needs for sun, soil type, moisture, and climate match the existing site conditions, minimizing resource inputs after establishment.

What is the primary environmental concern associated with using invasive plant species in US landscape design?

Answer: They can escape cultivation, outcompete native vegetation, and disrupt local ecosystems and biodiversity

Invasive plants spread beyond cultivated areas into natural ecosystems, out-competing native species, reducing biodiversity, and causing significant ecological and economic damage.

What is 'stormwater credit' in the context of sustainable landscape design and local regulations?

Answer: A reduction in stormwater utility fees or permit requirements granted to properties that manage runoff on-site through green infrastructure features

Many US municipalities offer stormwater credits as fee reductions to property owners who install green infrastructure like rain gardens, bioswales, or permeable paving that reduces runoff leaving the property.
