3. Which federal agency administers the National Forest system in the United States? → USDA Forest Service
4. What are the four major groups of functions of nature as classified by De Groot? → Production, regulation, carrier, information
5. 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
6. Which of the following diseases has been effectively managed through tree breeding for disease resistance? → Fusiform rust
7. The term 'cruise intensity' in a timber inventory refers to: → The percentage of the total area actually sampled
8. 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
9. Forest fragmentation analysis in GIS commonly relies on which type of landscape metrics to quantify patch size, shape, and connectivity? → FRAGSTATS metrics
10. Which forest product sector in the US uses the largest volume of wood by weight annually? → Pulp and paper
11. In the case of plant diseases, what are vectors? → Biotic factors that cause plant diseases
12. Which valuation tools are commonly used to estimate monetary values of functions not traded on the market? → Valuation tools and Cost-Benefit Analysis
13. What primary advantage does multispectral satellite imagery offer over traditional black-and-white aerial photography for forest mapping? → Ability to distinguish vegetation types based on spectral reflectance differences
14. Prescribed burning in silviculture is primarily used to: → Reduce fuel loads, control competition, and prepare seedbeds
15. When you eat a lot of meat, you waste a lot of heat because heat is lost between trophic levels. → 90%
16. What is 'stand volume' as used in timber inventory? → The total wood volume of all trees in a defined area, usually expressed per acre

22. Which soil property most directly controls the rate of infiltration? → Bulk density and porosity
23. Why is it important to know about a plant's environment and common diseases in order to figure out what's wrong with it? → To prevent unnecessary expenses and pesticide use
24. If a farmer wants to grow healthy crops, what should he look for? → Dark, clumpy soil & a neutral pH
