Green infrastructure quiz
- GSI=Green stormwater infrastructure
- GI=Green infrastructure
- Which of these is typically not considered a green stormwater infrastructure practice?
- Constructed wetland
- Permeable pavement
- Underground sand filter
- Vegetated filter strip
- True or false: All GSI practices are vegetated
- True or false: All vegetated GSI practices incorporate native vegetation into the practice
- Rank these in order of benefit for habitat
- Bioretention
- Constructed wetland
- Filter strip
- Green roof
- Rank these in order of benefit for energy savings
- Harvest and reuse
- Bioretention
- Green roof
- Which of these is likely not a benefit of native vegetation?
- Increases pollinator diversity
- Improves soil hydrologic function
- Reduces maintenance needs during establishment
- Provides habitat for a wider range of species (i.e. increases biodiversity)
- Explain
- Plugs are generally preferred over seed in establishing vegetation in bioretention practices
- Mulch is recommended in some GSI practices but not others
Answers
- Underground sand filter
- False: examples of non-vegetated practices include but are not limited to permeable pavement and underground infiltration
- False: while preferred in most situations, native vegetation is not necessary for practices considered to be GSI. An example would be irrigation of an athletic field from a harvest/reuse system.
- Constructed wetland > bioretention > green roof > filter strip
- Green roof > harvest/reuse > bioretention
- Reduces maintenance needs during establishment
- Explanations
- Seed is easily washed away in any practice involving moving water, including bioretention
- Mulch can inhibit seed germination and seedling growth and can also be washed away, depending on the mulch properties. However, mulch is recommended in practices where seedling establishment is not a concern. Mulch can provide several benefits, including soil protection, improved soil structure, and improved soil hydrology.
