1. What is the difference between functions and values in the context of nature and forests? → Functions are inherent to nature, while values are assigned by stakeholders
2. In the context of forest hydrology, what is a 'rain shadow'? → A dry area on the leeward side of a mountain range caused by orographic lifting
3. Which of the following best defines 'cubic foot' volume as used in US forest mensuration? → The actual wood volume of a section of stem including bark
4. Which federal agency administers the National Forest system in the United States? → USDA Forest Service
5. What are the four major groups of functions of nature as classified by De Groot? → Production, regulation, carrier, information
6. Which type of wetland provides the most critical breeding habitat for amphibians in eastern North American forests? → Isolated seasonal vernal pools without fish
7. Under the National Environmental Policy Act (NEPA), an Environmental Impact Statement (EIS) is required when a federal action is determined to have: → Significant effects on the quality of the human environment
8. Change detection analysis in forest remote sensing compares images from two or more dates to identify which of the following? → Areas where land cover or forest condition has changed over time
9. Which of the following diseases has been effectively managed through tree breeding for disease resistance? → Fusiform rust
10. The hedonic pricing method is used in forest valuation to estimate: → How proximity to forested areas affects nearby residential property values
11. The term 'cruise intensity' in a timber inventory refers to: → The percentage of the total area actually sampled
12. The commonly used term for the phenomenon where a shared and finite resource diminishes due to individuals prioritizing their own immediate benefits is → the tragedy of the commons
13. Forest fragmentation analysis in GIS commonly relies on which type of landscape metrics to quantify patch size, shape, and connectivity? → FRAGSTATS metrics
14. In a perfectly competitive timber market, stumpage price is driven to a level where: → The price equals the marginal cost of harvest and extraction
15. Which forest product sector in the US uses the largest volume of wood by weight annually? → Pulp and paper

19. Prescribed burning in silviculture is primarily used to: → Reduce fuel loads, control competition, and prepare seedbeds
20. What is the term for the phenomenon where species richness on habitat islands increases with island area? → Species-area relationship
21. The Humus-Carbonate soil type common in high-elevation spruce-fir forests is characterized by a thick accumulation of which organic layer? → Mor humus with a distinct Oi/Oe/Oa horizon sequence
22. When you eat a lot of meat, you waste a lot of heat because heat is lost between trophic levels. → 90%
23. What is 'stand volume' as used in timber inventory? → The total wood volume of all trees in a defined area, usually expressed per acre
