Silvicultural Systems Quiz

What is a silvicultural system?

• A method of planting crops in a forest.

• A planned program of silvicultural treatments designed to achieve specific stand structure characteristics.

• A system for managing wildlife in forests.

• A technique for measuring forest density.

Which of the following is NOT a basic goal of a silvicultural system?

• Provides for the availability of many forest resources.

• Produces planned harvests of forest products over the long term.

• Ensures the rapid growth of all plant species.

• Accommodates biological/ecological and economic concerns to ensure sustainability of resources.

What does a silvicultural system aim to minimize risks from?

• Overpopulation of wildlife.

• Stand-damaging agents such as insects, disease, and windthrow.

• Soil erosion.

• Water pollution.

What is the principal method of naming a silvicultural system based on?

• The type of soil in the forest.

• The principal method of regeneration and desired age structure.

• The climate of the region.

• The types of wildlife present.

Which of the following is a common objective of silvicultural systems on most sites?

• Maximizing the production of timber crops.

• Increasing the population of wildlife.

• Reducing the number of tree species.

• Increasing soil acidity.

What is a characteristic of even-aged stands?

• They have a highly broken or irregular canopy.

• They generally have a well-developed canopy with a regular top at a uniform height.

• They have three or more well-represented and well-defined age classes.

• They encourage deeper crowns and greater vertical structure in a stand.

What should be viewed cautiously in pure even-aged stands?

• Height distribution

• Canopy structure

• Diameter distribution

• Age class

What is the objective of the approach used in uneven-aged stands?

• To promote sustained regular harvests with short intervals at the stand level.

• To create a well-developed canopy with a regular top at a uniform height.

• To ensure all trees are in the average diameter class.

• To suppress the vigor of the overstory.

What does the broken canopy in uneven-aged stands allow for?

• Uniform height of trees

• Suppression of the overstory

• Greater light penetration and deeper crowns

• Well-developed canopy with a regular top

What is the primary purpose of reserves within a silvicultural system?

• To provide habitat, scenic, biodiversity, or other values for at least one rotation

• To increase the number of trees in a forest

• To reduce the cost of forest management

• To speed up the growth of new trees
