B. Ferns
C. Lichens
D. Epiphytes

Answer

To answer the question "Pioneers in the secondary succession of previously burnt forest are:", we can follow a step-by-step approach:

### Step-by-Step Solution:

1. **Understanding Secondary Succession**:
- Secondary succession occurs in areas where a disturbance (like a fire) has destroyed an existing ecosystem but left the soil intact. This allows for the regrowth of vegetation.

2. **Identifying the Cause of Disturbance**:
- In this case, the disturbance is a forest fire. Forest fires can be caused by natural events (like lightning) or human activities.

3. **Recognizing the Role of Pioneer Species**:
- After a fire, certain species are the first to recolonize the area. These are known as pioneer species. They are crucial for initiating the process of secondary succession.

4. **Identifying Pioneer Species in Burnt Forests**:
- The transcript mentions that the first species to colonize the area after a fire are herbaceous plants. Specifically, it points out that these can include conifers or ferns.

5. **Conclusion**:
- Therefore, the pioneers in the secondary succession of a previously burnt forest are primarily **ferns** or **conifers**.

### Final Answer:
The pioneers in the secondary succession of previously burnt forest are **ferns** or **conifers**.
