CF Forest Management and Planning 2 — Questions and Answers
Question 1: What is the primary purpose of a forest management plan's compartment description?
- To record timber sale revenue projections
- To document stand conditions, species composition, and recommended treatments for each management unit (Correct answer)
- To list all wildlife species observed in the compartment
- To track historical fire frequency within each unit
Correct answer: To document stand conditions, species composition, and recommended treatments for each management unit
Compartment descriptions document current stand conditions, species mix, stocking, and prescriptions to guide management decisions within each unit.
Question 2: Which silvicultural system is most appropriate for managing shade-tolerant species like sugar maple in an uneven-aged structure?
- Clearcutting
- Shelterwood
- Seed tree
- Selection system (Correct answer)
Correct answer: Selection system
The selection system maintains uneven-aged structure by periodically harvesting individual or small groups of trees, favoring shade-tolerant regeneration.
Question 3: In forest planning, what does 'sustained yield' mean?
- Maximizing timber harvest in any given year
- Harvesting no more volume than the forest can regrow over the planning period (Correct answer)
- Maintaining a constant workforce year-round
- Ensuring the same species composition is preserved indefinitely
Correct answer: Harvesting no more volume than the forest can regrow over the planning period
Sustained yield means harvest levels do not exceed forest growth over time, ensuring long-term productivity.
Question 4: A forester calculates that a stand has a basal area of 180 sq ft/acre but the target is 120 sq ft/acre. What management action is indicated?
- Planting additional seedlings
- Thinning to reduce stocking (Correct answer)
- Applying fertilizer to stimulate growth
- Converting to a different species
Correct answer: Thinning to reduce stocking
When actual basal area exceeds the management target, thinning removes excess trees to improve growth rates of residuals.
Question 5: Which of the following best describes the 'culmination of mean annual increment' (CMAI)?
- The age at which a tree first produces seed
- The age at which the average annual volume growth over a tree's life is maximized (Correct answer)
- The point at which a stand reaches full canopy closure
- The year in which a forest achieves its highest total standing volume
Correct answer: The age at which the average annual volume growth over a tree's life is maximized
CMAI is the rotation age at which mean annual increment peaks, representing the biologically optimal harvest time.
Question 6: What is the key difference between even-aged and uneven-aged management in terms of stand structure?
- Even-aged stands contain multiple species; uneven-aged stands are monocultures
- Even-aged stands have trees of similar age; uneven-aged stands have trees of multiple age classes simultaneously (Correct answer)
- Even-aged management never uses clearcutting
- Uneven-aged management always produces more timber per acre
Correct answer: Even-aged stands have trees of similar age; uneven-aged stands have trees of multiple age classes simultaneously
Even-aged management produces cohorts of similar-age trees, while uneven-aged management maintains a continuous range of age and size classes.
Question 7: A forest management plan identifies 'old-growth retention areas.' What is the primary management objective for these areas?
- Maximizing timber volume production
- Preserving ecological structure, biological diversity, and late-successional habitat (Correct answer)
- Establishing tree plantations of commercially valuable species
- Reducing fuel loads to prevent wildfire ignition
Correct answer: Preserving ecological structure, biological diversity, and late-successional habitat
Old-growth retention areas are managed to protect structural complexity, biodiversity, and late-successional ecosystem functions.
