CGM Sustainable Practices & Conservation 3 — Questions and Answers
Question 1: A grounds manager notices a significant decline in bee populations on the property. Which action best supports pollinator conservation?
- Increase systemic insecticide applications
- Establish pollinator habitat with diverse native flowering plants (Correct answer)
- Remove all flowering weeds immediately
- Install additional lighting to extend daylight hours
Correct answer: Establish pollinator habitat with diverse native flowering plants
Establishing diverse native flowering habitat provides food and nesting resources that support bee and other pollinator populations.
Question 2: Which carbon sequestration practice can a grounds manager implement to help offset greenhouse gas emissions on a large turf property?
- Increase mowing frequency to stimulate growth
- Convert select turf areas to trees and woody shrubs (Correct answer)
- Apply synthetic nitrogen fertilizers more frequently
- Install concrete paths throughout the property
Correct answer: Convert select turf areas to trees and woody shrubs
Trees and woody shrubs sequester significantly more carbon per square foot than turf, making conversion a meaningful climate mitigation strategy.
Question 3: What is the recommended buffer width of un-mowed vegetation along a water body to help filter runoff?
- 1–3 feet
- 5–10 feet
- 25–100 feet or more depending on slope (Correct answer)
- 200 feet minimum nationwide
Correct answer: 25–100 feet or more depending on slope
Vegetative buffer widths of 25–100+ feet (varying by slope, soil, and regulation) effectively filter sediments, nutrients, and pesticides before they reach water.
Question 4: Which certification program helps grounds managers demonstrate commitment to environmental stewardship in turf management?
- LEED for Homes
- Audubon Cooperative Sanctuary Program (Correct answer)
- OSHA 10-Hour Certification
- EPA SmartWay Transport Partnership
Correct answer: Audubon Cooperative Sanctuary Program
The Audubon Cooperative Sanctuary Program recognizes facilities that implement sustainable environmental practices in landscape management.
Question 5: A grounds manager wants to reduce fertilizer runoff into a nearby pond. Which nutrient management strategy is most effective?
- Apply fertilizers before heavy rain events to integrate them quickly
- Use slow-release fertilizers and apply based on soil test recommendations (Correct answer)
- Apply the maximum labeled rate to reduce application frequency
- Broadcast fertilizers evenly across all areas including buffer zones
Correct answer: Use slow-release fertilizers and apply based on soil test recommendations
Slow-release fertilizers reduce leaching and runoff, while soil test-based applications prevent over-fertilization.
Question 6: What is the environmental advantage of using electric-powered grounds equipment over gas-powered equipment?
- Electric equipment always costs less to purchase
- Electric equipment produces zero direct air emissions during operation (Correct answer)
- Electric equipment requires no maintenance
- Electric equipment performs better in wet conditions
Correct answer: Electric equipment produces zero direct air emissions during operation
Electric equipment produces no direct exhaust emissions during use, reducing air pollution and greenhouse gas output at the point of operation.
Question 7: Which practice in composting yard waste on-site best demonstrates a circular economy approach to grounds management?
- Landfilling clippings to free up storage space
- Returning organic matter to the landscape as compost (Correct answer)
- Burning plant debris to reduce volume
- Selling all clippings to off-site facilities
Correct answer: Returning organic matter to the landscape as compost
On-site composting returns nutrients and organic matter back to the soil, closing the nutrient loop and reducing off-site waste.
