Study Notes
Clear-Cutting and Forestry Practices
- Clear Cutting: A logging method where most or all trees in a designated area are felled, often leading to ecological disruption.
- Selective Cutting: Involves harvesting only specific mature trees, promoting wildlife habitats and enhancing forest regeneration, though it is generally more costly.
Environmental Challenges
- Desertification: A process resulting in over 10% loss of land productivity, primarily driven by factors like erosion, deforestation, and overgrazing affecting soil health.
- Industrial Agriculture: Characterized by the heavy use of fossil fuels, water, and chemical inputs to produce large-scale, often mono-cropped agricultural outputs.
Forest Management Techniques
- Prescribed Burn: A controlled fire technique utilized to manage forest health and reduce the risk of uncontrolled wildfires, promoting biodiversity.
- Reforestation: The process of re-establishing forest cover by natural regeneration or planting methods after logging or deforestation.
Land Use Methods
- Slash-and-Burn: A traditional method that involves clearing land by cutting and burning forests to prepare for agricultural use, frequently used in tropical regions.
Resource Management Concepts
- Reserves: Identified resource deposits that have potential for future use, critical for sustainable resource management.
- Resistance: The interplay of biotic and abiotic elements limiting population growth, crucial in understanding ecological balance.
Sustainability Principles
- Sustainability: The ability of Earth's systems to not only endure but also adapt over time to changing environmental conditions, ensuring future ecological health.
