Panna, a district in the central Indian state of Madhya Pradesh is known for its dynamic dry forests, its grasslands, deep gorges with waterfalls and the Ken river, which cuts through the forest and is its lifeline. Nestled in these forests is Panna Tiger Reserve, an eco-paradise and safe haven for animals, especially tigers. It is a tourist attraction, and a great place to learn about conservation efforts. But Panna Tiger Reserve also hides a secret that tourists often don’t notice — illegal diamond mining.
