With reference to India's Desert National Park, which of the following statements are correct? 1. It is spread over two districts. 2. There is no human habitation inside the Park. 3. It is one of the natural habitats of Great Indian Bustard. Select the correct answer using the code given below:

Let's evaluate the statements regarding India's Desert National Park:

1. It is spread over two districts: This statement is correct. The Desert National Park (DNP) is located in the state of Rajasthan and covers a vast area that spans across two districts: Jaisalmer and Barmer. It is one of the largest national parks in India.

2. There is no human habitation inside the Park: This statement is incorrect. Unlike some national parks where human habitation is strictly prohibited or relocated, the Desert National Park has several villages and human settlements within its boundaries. Local communities, including traditional pastoralists, reside in and around the park area and have historically coexisted with its wildlife. The park's management plan often incorporates the needs and rights of these communities.

3. It is one of the natural habitats of Great Indian Bustard: This statement is correct. The Desert National Park is critically important as one of the last remaining strongholds and natural habitats for the critically endangered Great Indian Bustard (GIB). The park's arid grasslands and scrublands provide the ideal environment for this iconic bird, and significant conservation efforts for the GIB are concentrated in this region.

Therefore, statements 1 and 3 are correct.
