B.F. Bachelor of Forestry Bachelor of Forestry Wildlife Management 4 — Questions and Answers
Question 1: Which type of prescribed fire application is used to reduce fuel loads and improve wildlife habitat by burning against the direction of wind spread?
- Head fire
- Backing fire (Correct answer)
- Flanking fire
- Spot fire
Correct answer: Backing fire
A backing fire burns slowly into the wind, producing lower flame lengths and heat intensity, making it safer and more controllable for habitat management objectives.
Question 2: The Pittman-Robertson Federal Aid in Wildlife Restoration Act funds state wildlife programs primarily through which mechanism?
- General federal income tax revenues allocated by Congress
- An excise tax on sporting arms, ammunition, and archery equipment (Correct answer)
- Hunting license fee surcharges collected by states
- Annual appropriations from the Land and Water Conservation Fund
Correct answer: An excise tax on sporting arms, ammunition, and archery equipment
Pittman-Robertson (1937) places an excise tax of 10–11% on firearms and ammunition, with revenues distributed to states for wildlife restoration and hunter education.
Question 3: What is the purpose of a 'nest box program' implemented by a wildlife biologist in a managed forest?
- To monitor invasive species reproduction
- To supplement natural cavity availability for secondary cavity-nesting species (Correct answer)
- To provide nesting structures for raptors on utility poles
- To attract colonial waterbirds away from sensitive wetlands
Correct answer: To supplement natural cavity availability for secondary cavity-nesting species
Nest boxes compensate for the scarcity of natural cavities in intensively managed forests, directly benefiting species like wood ducks, screech owls, and bluebirds.
Question 4: Population viability analysis (PVA) is primarily used in wildlife management to:
- Calculate maximum sustainable harvest quotas for game species
- Estimate the probability of a population persisting over a specified time period (Correct answer)
- Map suitable habitat using remote sensing data
- Determine optimal stocking densities for game fish
Correct answer: Estimate the probability of a population persisting over a specified time period
PVA uses demographic and stochastic models to estimate extinction risk, helping managers identify minimum viable population sizes and critical threats.
Question 5: Which concept describes how different species in a community partition resources to reduce direct competition and allow coexistence?
- Competitive exclusion
- Niche differentiation (Correct answer)
- Interspecific facilitation
- Trophic cascade
Correct answer: Niche differentiation
Niche differentiation occurs when species exploit different resources, microhabitats, or times of activity, reducing overlap and enabling stable coexistence.
Question 6: A wildlife manager finds that wild turkey poult survival is extremely low. Which habitat feature, if improved, would MOST directly increase poult survival?
- Old-growth timber stands with closed canopy
- Brood habitat with herbaceous ground cover and insect abundance (Correct answer)
- Dense brushy thickets for adult roosting
- Large wetland complexes for water access
Correct answer: Brood habitat with herbaceous ground cover and insect abundance
Turkey poults require open, herbaceous brood habitat rich in insects for protein; without this specific habitat, poult starvation and predation losses are severe.
Question 7: Which term describes the annual home range pattern where an animal uses different seasonal areas for breeding, wintering, and feeding?
- Dispersal
- Seasonal migration or seasonal movement (Correct answer)
- Philopatry
- Nomadism
Correct answer: Seasonal migration or seasonal movement
Seasonal movement or migration involves predictable shifts between distinct areas used at different times of year, driven by resource availability and reproductive needs.
