Why are green fuels being burned?
- Green fuels, like live vegetation and fresh leaves, burn when exposed to prolonged heat, which removes their moisture.
- In forest fires, intense conditions can dry and ignite these fuels, making them flammable.
P3. rescribed burns and natural wildfires consume green fuels to reduce future fire risks and maintain ecological balance.
Fire as a tool in the reforestation of Benguet pine forests
- Fire clears undergrowth, allowing sunlight to reach Benguet pine (Pinus kesiya) seedlings.
- Controlled burns reduce competition from other plant species and enhance natural seed germination.
- Properly managed fire prevents excessive damage to mature trees and minimizes soil degradation.
Beneficial effects of fire
- Clears dead vegetation, promoting new plant growth and maintaining ecosystem balance.
- Recycles nutrients back into the soil, improving fertility and supporting regeneration.
- Creates diverse habitats, increasing biodiversity by opening spaces for new species.
Harmful effects of fire
- Destroys habitats, reduces biodiversity, and releases harmful smoke and greenhouse gases.
- Causes soil erosion and degradation, leading to increased risk of landslides and water loss.
- Weakens forest ecosystems, making them more vulnerable to climate change and environmental stress.
