CORE CORE Natural Resource Management 4 — Questions and Answers
Question 1: Which federal agency is primarily responsible for managing National Forests in the United States?
- U.S. Fish and Wildlife Service
- National Park Service
- U.S. Forest Service (Correct answer)
- Bureau of Land Management
Correct answer: U.S. Forest Service
The U.S. Forest Service, part of the USDA, manages approximately 193 million acres of National Forest lands for multiple uses including timber, recreation, and wildlife habitat.
Question 2: What is the primary purpose of a wildlife corridor?
- To provide designated hunting zones
- To connect fragmented habitat patches allowing animal movement (Correct answer)
- To create buffer zones around urban areas
- To define state boundary lines for game management
Correct answer: To connect fragmented habitat patches allowing animal movement
Wildlife corridors link isolated habitat fragments, allowing animals to move between areas for breeding, foraging, and migration, which improves genetic diversity and population health.
Question 3: A stream running through a forested area suddenly shows a spike in nitrate levels. What is the most likely cause?
- Increased beaver activity upstream
- Agricultural fertilizer runoff from nearby fields (Correct answer)
- Natural decomposition of fallen leaves
- Migration of anadromous fish species
Correct answer: Agricultural fertilizer runoff from nearby fields
Excess nitrates in waterways most commonly result from agricultural fertilizer runoff, which can cause algal blooms and hypoxic conditions harmful to aquatic life.
Question 4: What does the term 'carrying capacity' refer to in wildlife management?
- The legal bag limit set by state wildlife agencies
- The maximum number of animals a habitat can sustainably support (Correct answer)
- The total weight of game harvested per season
- The distance animals travel during annual migration
Correct answer: The maximum number of animals a habitat can sustainably support
Carrying capacity is the maximum population size that an environment can sustain indefinitely given available food, water, shelter, and space.
Question 5: Which of the following best describes the concept of 'edge habitat'?
- The deepest section of a lake where cold-water species reside
- The boundary zone where two different habitat types meet (Correct answer)
- A coastal wetland at the edge of the ocean
- The outermost boundary of a state wildlife management area
Correct answer: The boundary zone where two different habitat types meet
Edge habitat is the transitional zone between two different ecosystems, such as forest and meadow, and often supports higher biodiversity because species from both habitats can use it.
Question 6: Prescribed burns are used by land managers primarily to:
- Eliminate all non-native plant species permanently
- Reduce fuel loads and promote habitat diversity (Correct answer)
- Mark property boundaries for hunting leases
- Destroy invasive animal burrows and dens
Correct answer: Reduce fuel loads and promote habitat diversity
Prescribed burns reduce accumulated dead vegetation that could fuel catastrophic wildfires and stimulate new plant growth that benefits wildlife by creating diverse habitat structure.
Question 7: What is 'riparian habitat' and why is it important for wildlife?
- Rocky mountain terrain that provides denning sites for large predators
- Vegetated areas along rivers and streams that support high biodiversity (Correct answer)
- Open grasslands used as primary feeding areas for migratory birds
- Dense boreal forest providing thermal cover in winter months
Correct answer: Vegetated areas along rivers and streams that support high biodiversity
Riparian habitat consists of the plant communities along stream and river banks; it provides water, food, and shelter for a disproportionately high number of wildlife species relative to its area.
