This question asks to identify the Tiger Reserve where the Maikal range is a significant landform, oriented north-south. Let's analyze the options provided in relation to the Maikal range.

Understanding the Maikal Range

The Maikal range, also known as the Maikal hills, is an eastern part of the Satpura Range. It is located in the Indian state of Madhya Pradesh and Chhattisgarh. This range is known for its unique biodiversity and serves as a crucial geographical feature in central India. Its characteristic north-south orientation is a key identifier.

Connecting Maikal Range to Tiger Reserves

We need to determine which of the listed Tiger Reserves is most associated with the Maikal range as its prominent landform.

• Kanha Tiger Reserve: Located in Madhya Pradesh, Kanha is renowned for its scenic beauty, dense forests, and grasslands. The Maikal range forms a significant part of its eastern and northeastern boundary, influencing its topography and ecosystem. The hills provide a backdrop and contribute to the landscape's distinctiveness.
• Bori Tiger Reserve: Bori is located in Madhya Pradesh, known for its deciduous forests. While part of the Satpura-Maikal landscape, it's not typically highlighted as being *defined* by the Maikal range in the same way Kanha is.
• Sanjay Tiger Reserve: Situated in Madhya Pradesh and Chhattisgarh, Sanjay Tiger Reserve is also near the Maikal hills, but the Maikal range isn't described as its *most prominent* landform compared to Kanha.
• Pench Tiger Reserve: Located in Madhya Pradesh and Maharashtra, Pench is known for the Seoni hills and the Pench River. It lies southwest of the Maikal range and is not directly characterized by it as a prominent landform.

Maikal Range's Prominence in Kanha

The Maikal range plays a vital role in the geography of Kanha Tiger Reserve. The hills influence the drainage patterns and habitat diversity within the reserve. The north-south direction mentioned in the question aligns well with the orientation of the Maikal hills as they extend into the region surrounding Kanha.

Therefore, the Maikal range is considered the most prominent landform associated with Kanha Tiger Reserve among the given options.
