Renewable Resources
Resources that can be replenished naturally, such as soil and forests.
Nonrenewable Resources
Resources that cannot be replenished naturally within a human lifespan, such as fossil fuels.
Sustainability
Resource use that occurs only as fast as it can be naturally replaced.
Maximum Sustainable Yield (MSY)
The maximum amount of resources that can be harvested without compromising future harvests.
Carrying Capacity
The maximum population size that an environment can sustain.
Ecosystem-Based Forest Management
Management approach aimed at harvesting resources while minimizing effects on the ecosystem.
Adaptive Forest Management
Management strategy that involves gathering data and adjusting practices based on results.
Ecological Value of Forests
Includes providing habitat, preventing erosion, and storing carbon.
Economic Value of Forests
Includes timber for lumber and fuel, and as a source of food and medicines.
Clear-Cutting
A logging method involving the removal of all trees in an area.
Seed-Tree Method
A logging method that leaves a small number of mature trees to reseed the area.
Shelterwood Method
A logging method where some trees are left to provide shelter for seedlings.
Selection System
A logging method that allows for cutting only a few trees at a time.
Deforestation
The permanent removal of forested areas for other land uses.
Old-Growth Forest
A forest that has never been logged.
U.S. National Forests
Established to grow trees for timber and protect watersheds; managed by the U.S. Forest Service.
National Forest Management Act (1976)
Requires renewable resource management plans for each national forest.
Logging on Private Land
Most logging occurs on privately owned plantations, often composed of monocultures.
Fire Suppression
Efforts to control fires that can have negative ecological consequences.
Prescribed Burns
Controlled burns to reduce fuel buildup and restore ecosystems.
Healthy Forests Restoration Act (2003)
Encourages practices like prescribed burns and salvage logging.

Erosion
The process of moving soil or material from one location to another.
Intercropping
Growing different crops in proximity for benefits such as reduced erosion.
Crop Rotation
Alternating different crops in the same area across seasons.
Shelterbelts
Rows of trees or tall plants that block wind and protect crops from erosion.
Conservation Tillage
A farming practice that minimizes soil disturbance.
Terracing
The practice of shaping the landscape into steps to reduce soil erosion.
Contour Farming
Planting crops across the slope of the land to prevent erosion.
U.S. Soil Conservation Act (1935)
Established the Soil Conservation Service to combat soil erosion.
