B.S.F. or B.Sc.F. Bachelor of Science in Forestry Silviculture and Forest Stand Management 1 — Questions and Answers
Question 1: Which silvicultural system removes all trees in a stand simultaneously, creating an even-aged forest?
- Selection system
- Shelterwood system
- Clearcutting system (Correct answer)
- Coppice system
Correct answer: Clearcutting system
Clearcutting removes all trees at once and is the primary method for establishing even-aged stands.
Question 2: What is the primary goal of thinning in a forest stand?
- Eliminate all undergrowth
- Concentrate growth on the best trees by reducing competition (Correct answer)
- Increase the number of stems per acre
- Remove only dead trees
Correct answer: Concentrate growth on the best trees by reducing competition
Thinning reduces stand density so that remaining crop trees receive more light, water, and nutrients.
Question 3: The shelterwood silvicultural system is best described as:
- Removing all trees in one cut
- Removing trees in a series of cuts to regenerate under partial canopy (Correct answer)
- Selecting and removing individual mature trees throughout the rotation
- Coppicing stumps after harvest
Correct answer: Removing trees in a series of cuts to regenerate under partial canopy
The shelterwood system uses sequential harvests that retain overstory trees to provide shade and seed for regeneration before final removal.
Question 4: Which regeneration method relies on vegetative sprouting from stumps or roots?
- Seed-tree method
- Coppice system (Correct answer)
- High forest system
- Selection system
Correct answer: Coppice system
The coppice system regenerates forests through stump sprouts (epicormic shoots) rather than seeds.
Question 5: In the US, 'release cutting' in silviculture refers to:
- Final harvest of mature timber
- Removing overtopping vegetation to free a desired crop tree (Correct answer)
- Planting seedlings after clearcutting
- Prescribed burning to stimulate seed germination
Correct answer: Removing overtopping vegetation to free a desired crop tree
Release cutting removes competing vegetation that suppresses desired crop trees, freeing them from overtopping competition.
Question 6: What is a 'rotation age' in forestry?
- Age at which a tree begins producing seed
- The number of years between prescribed burns
- The planned age at which a stand is harvested (Correct answer)
- Time required for a clearcut area to reach canopy closure
Correct answer: The planned age at which a stand is harvested
Rotation age is the planned number of years from stand establishment to final harvest.
