B.F. Bachelor of Forestry Bachelor of Forestry Wildlife Management 5 — Questions and Answers
Question 1: Which federal designation provides the strongest legal protection for species at risk of extinction in the United States?
- Forest Service Special Management Area
- Endangered Species Act listing as Threatened or Endangered (Correct answer)
- Wildlife Management Area designation by state agencies
- National Park Service Sensitive Species classification
Correct answer: Endangered Species Act listing as Threatened or Endangered
ESA listing triggers Section 7 consultation, Section 9 take prohibitions, and critical habitat designation, making it the most powerful federal wildlife protection tool.
Question 2: What is the ecological role of apex predators such as wolves in forested ecosystems according to trophic cascade theory?
- They compete with herbivores for plant biomass, reducing forest productivity
- They suppress herbivore populations and behavior, indirectly allowing vegetation recovery (Correct answer)
- They primarily regulate other predator populations with no plant-level effects
- They increase disease transmission rates by concentrating prey near water sources
Correct answer: They suppress herbivore populations and behavior, indirectly allowing vegetation recovery
Trophic cascades from apex predators reduce ungulate density and alter grazing behavior (landscape of fear), allowing streamside vegetation and forest understory to recover.
Question 3: In designing a wildlife management plan, which element represents the specific, measurable outcomes a manager aims to achieve within a defined timeframe?
- Goals
- Objectives (Correct answer)
- Strategies
- Monitoring protocols
Correct answer: Objectives
Objectives are SMART (Specific, Measurable, Achievable, Relevant, Time-bound) statements that define precise outcomes, unlike broader goal statements.
Question 4: Which remote sensing technique is increasingly used by wildlife managers to survey large ungulate or waterfowl populations from aircraft without ground disturbance?
- Side-scan sonar
- Thermal infrared imagery (Correct answer)
- Ground-penetrating radar
- Passive acoustic monitoring
Correct answer: Thermal infrared imagery
Thermal infrared cameras detect heat signatures of animals against cooler backgrounds, enabling accurate aerial counts even in dense vegetation or low light.
Question 5: A forest manager notices that northern bobwhite quail populations have crashed on a managed property. Which single habitat factor is MOST likely limiting their recovery?
- Absence of permanent water sources
- Loss of bunchgrass and native warm-season grass cover for nesting and brooding (Correct answer)
- Overabundance of white-tailed deer competing for food
- Insufficient tree cover for winter roosting
Correct answer: Loss of bunchgrass and native warm-season grass cover for nesting and brooding
Bobwhite quail require native warm-season grasses and shrubby edges for nesting and brood cover; row-crop agriculture and fescue monocultures have eliminated this habitat across much of their range.
Question 6: Which best describes the difference between 'consumptive' and 'non-consumptive' wildlife uses in a management context?
- Consumptive use involves endangered species; non-consumptive involves game species
- Consumptive use removes animals from the population (hunting, trapping); non-consumptive use does not (birdwatching, photography) (Correct answer)
- Consumptive use degrades habitat; non-consumptive use always improves it
- Consumptive use is regulated by states; non-consumptive use is federally regulated
Correct answer: Consumptive use removes animals from the population (hunting, trapping); non-consumptive use does not (birdwatching, photography)
Consumptive wildlife uses involve harvesting or removing animals, while non-consumptive uses involve observing or photographing wildlife without removal.
Question 7: What silvicultural system best replicates the natural disturbance regime of fire-dependent longleaf pine ecosystems to benefit Red-cockaded Woodpeckers?
- Clearcut with replanting on a 25-year rotation
- Uneven-aged selection creating a closed multilayered canopy
- Even-aged management with frequent prescribed fire maintaining open park-like structure (Correct answer)
- Shelterwood harvesting retaining a dense overstory seed source
Correct answer: Even-aged management with frequent prescribed fire maintaining open park-like structure
Red-cockaded Woodpeckers require open park-like longleaf pine stands maintained by frequent prescribed fire that prevents midstory encroachment and keeps foraging habitat accessible.
