When collecting firewood in the wild, you need to pay special attention to environmental protection and legal regulations. Many places have explicit regulations prohibiting the random collection of plants and wood in the wild, so the best way is to prepare some firewood in advance or buy it at designated locations. If you really want to collect firewood, it is recommended to follow the following principles: 1. **Choose dry branches**: Look for dry branches or dead wood that have fallen to the ground. These usually do not attract attention and reduce damage to the environment. 2. **Follow the principle of "taking in moderation"**: Please do not collect excessively, collect according to actual needs, and do not affect the ecological environment. 3. **Avoid lush vegetation**: When collecting, try to avoid areas with lush leaves, so that the traces of collection are not easy to be discovered. In addition, choose to collect near the trail to reduce interference with the natural environment. 4. **Pay attention to the surrounding environment**: When collecting firewood, pay attention to the people and environment around you, and choose a time and place with few people to avoid being discovered by others. 5. **Follow local regulations**: In some areas, collecting firewood in the wild may be illegal, so be sure to understand the relevant local regulations in advance and respect the regulations of the nature reserve. The best approach is to bring your own firewood, or find a place near your picnic where you can legally collect it to ensure environmental protection and compliance.
