CPRP Environmental Stewardship and Sustainability 4 — Questions and Answers
Question 1: A park district wants to reduce its carbon footprint from fleet vehicles. Which alternative fuel option is BEST suited for short-range maintenance vehicles that return to a central depot nightly?
- Compressed natural gas (CNG)
- Battery electric vehicles (BEV) (Correct answer)
- Hydrogen fuel cell vehicles
- Biodiesel B20 blend
Correct answer: Battery electric vehicles (BEV)
Battery electric vehicles are ideal for short-range, depot-return operations because overnight charging is convenient and eliminates tailpipe emissions entirely.
Question 2: Which metric is most commonly used to measure the ecological health of a stream running through a park?
- Dissolved oxygen concentration (Correct answer)
- Water temperature at noon
- Total annual precipitation
- Shoreline vegetation density
Correct answer: Dissolved oxygen concentration
Dissolved oxygen (DO) is a primary indicator of aquatic ecosystem health because most aquatic organisms require adequate oxygen levels to survive.
Question 3: A park manager discovers an invasive plant species covering 5% of a natural area. Under integrated pest management (IPM), what is the FIRST recommended step?
- Apply broad-spectrum herbicide immediately
- Identify the species and assess its spread rate (Correct answer)
- Remove all vegetation in the affected zone
- Install exclusion fencing around the area
Correct answer: Identify the species and assess its spread rate
IPM begins with accurate identification and assessment to determine the threat level before selecting the least-invasive treatment method.
Question 4: Which LEED credit category is most directly relevant when a recreation center installs low-flow toilets and waterless urinals?
- Energy and Atmosphere
- Water Efficiency (Correct answer)
- Materials and Resources
- Indoor Environmental Quality
Correct answer: Water Efficiency
Low-flow fixtures and waterless urinals directly reduce potable water consumption, which is addressed under LEED's Water Efficiency credit category.
Question 5: A parks department is developing a climate adaptation plan. Which strategy specifically addresses the urban heat island effect in park design?
- Installing permeable pavement in parking lots
- Increasing tree canopy cover and shade structures (Correct answer)
- Constructing bioswales along park perimeters
- Replacing turf with native groundcovers
Correct answer: Increasing tree canopy cover and shade structures
Expanding tree canopy cover reduces surface and air temperatures through evapotranspiration and shade, directly mitigating the urban heat island effect.
Question 6: Which federal law primarily governs the protection of migratory birds that nest in park habitats?
- Endangered Species Act (ESA)
- Migratory Bird Treaty Act (MBTA) (Correct answer)
- National Environmental Policy Act (NEPA)
- Clean Water Act (CWA)
Correct answer: Migratory Bird Treaty Act (MBTA)
The Migratory Bird Treaty Act prohibits the take, possession, import, and export of migratory birds without authorization.
Question 7: A recreation agency is evaluating its solid waste program. Which waste hierarchy level should be prioritized ABOVE recycling?
- Landfill disposal
- Composting
- Source reduction (Correct answer)
- Energy recovery
Correct answer: Source reduction
The waste management hierarchy prioritizes source reduction (prevention) above all other strategies, including recycling and composting, because it eliminates waste before it is created.
