FM FM Wildlife & Biodiversity Management 1 — Questions and Answers
Question 1: Which forest structural feature is most critical for cavity-nesting wildlife species such as woodpeckers and owls?
- Dense shrub layer
- Large-diameter standing dead trees (snags) (Correct answer)
- Uniform canopy closure
- Grass understory
Correct answer: Large-diameter standing dead trees (snags)
Large-diameter snags provide essential nesting and roosting cavities for dozens of wildlife species, making their retention a priority in forest management for biodiversity.
Question 2: The 'edge effect' in wildlife habitat refers to:
- Reduced tree growth at the edge of a property
- Increased species diversity and activity along boundaries between different habitat types (Correct answer)
- Wind damage to trees at forest perimeters
- Property line disputes between landowners
Correct answer: Increased species diversity and activity along boundaries between different habitat types
The edge effect describes the often-elevated wildlife diversity and activity found along the transition zones between different habitats, though it can also favor generalist species over forest interior specialists.
Question 3: What is the primary objective of maintaining 'coarse woody debris' (CWD) in managed forests?
- Fuel load management for fire prevention
- Provide habitat, nutrient cycling, and moisture retention for a wide range of organisms (Correct answer)
- Improve access for logging equipment
- Prevent invasive plant establishment
Correct answer: Provide habitat, nutrient cycling, and moisture retention for a wide range of organisms
Coarse woody debris—fallen logs and large branches—is critical habitat for reptiles, amphibians, invertebrates, fungi, and plants, while also contributing significantly to soil nutrient cycling.
Question 4: A 'wildlife tree' in forest management is specifically defined as:
- Any tree planted for wildlife food
- A designated live or dead tree retained in harvested areas for its wildlife habitat value (Correct answer)
- A tree species preferred by deer for browsing
- A tree certified under a wildlife conservation program
Correct answer: A designated live or dead tree retained in harvested areas for its wildlife habitat value
Wildlife trees are specifically designated trees—often large, old, or with existing cavities—that are protected from harvest to maintain structural complexity and habitat for cavity-dependent species.
Question 5: Maintaining a 'diversity of stand ages' across a landscape primarily benefits wildlife by:
- Increasing total timber volume
- Providing the range of habitat conditions needed by different species at different life stages (Correct answer)
- Reducing wildfire risk
- Simplifying management planning
Correct answer: Providing the range of habitat conditions needed by different species at different life stages
Different wildlife species require different forest structural conditions—early successional shrubfields, mid-rotation forests, and old-growth all support distinct wildlife communities.
Question 6: Which of the following management actions best benefits forest interior bird species?
- Creating numerous small clearcuts throughout the forest
- Maintaining large blocks of unfragmented mature forest (Correct answer)
- Planting ornamental trees along forest roads
- Increasing the number of forest roads for access
Correct answer: Maintaining large blocks of unfragmented mature forest
Forest interior birds like neotropical migrants avoid forest edges and require large, intact blocks of mature forest away from disturbance, fragmentation, and nest predators associated with edges.
