Chapter 11 Forestry and Resource Management!

Front

What is the selection system in timber harvesting?

Back

The selection system is a method of timber harvesting that aims to produce a future forest that closely resembles the original forest in terms of biodiversity by selectively removing certain trees.

Front

What does the National Forest Management Act require?

Back

The National Forest Management Act requires plans for renewable resource management to be drawn up, consistent with the concepts of multiple use yield, maximum sustainable yield, and allows increases in harvest levels only if sustainable.

Front

What is the goal of maximum sustainable yield management?

Back

The goal of maximum sustainable yield management is to harvest resources in ways that minimize impact on the ecosystems and ecological processes that provide the resource.

Front

What defines a renewable resource harvested sustainably?

Back

A renewable resource is harvested sustainably if the amount of replacement is equal to the amount harvested.

Front

What is fire suppression?

Back

Fire suppression is the act of actively fighting or preventing fires from spreading.

Front

What is clear-cutting in forestry?

Back

Clear-cutting is a timber harvesting method where all trees in a designated area are cut down, which can lead to significant changes in the ecosystem.

Front

What is the shelterwood approach in timber harvesting?

Back

The shelterwood approach is a method of timber harvesting that involves removing trees in phases to establish a new generation of trees under the protection of older trees.

Front

What is the concept of multiple use yield?

Back

Multiple use yield refers to the management of forest resources to provide a variety of benefits, including timber, recreation, wildlife habitat, and water quality.

Front

What is maximum sustainable yield?

Back

Maximum sustainable yield is the largest yield (or catch) that can be taken from a specific fishery or resource over an indefinite period under constant environmental conditions.

Front

What are the ecological impacts of fire suppression?

Back

Fire suppression can lead to the accumulation of fuel (dead trees and underbrush), increasing the risk of larger, uncontrolled wildfires and negatively impacting certain ecosystems that depend on fire.
