Answer

To answer the question about the parameters used for the tiger census in national parks and sanctuaries in our country, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Census**:
- A census is a systematic method used to count and assess the population of a particular species in a defined area. This involves gathering data on various aspects of the population.

2. **Parameters for Tiger Census**:
- In the context of tigers, two key parameters are primarily used for conducting the census:
- **Pug Marks**: These are the footprints left by tigers. They help researchers identify the presence of tigers in a specific area and can provide information about their movement patterns.
- **Fecal Pellets**: These are the droppings of tigers. Analyzing fecal pellets can provide insights into the diet, health, and population density of tigers in the area.

3. **Importance of Both Parameters**:
- Relying solely on pug marks or fecal pellets would not give a complete picture of the tiger population. Therefore, both parameters are essential for an accurate census.

4. **Conclusion**:
- The parameters used for the tiger census in national parks and sanctuaries are both **pug marks** and **fecal pellets**.

### Final Answer:
The parameters used for the tiger census in our country's national parks and sanctuaries are **pug marks and fecal pellets**.
