Conservation of Flora and Fauna in Karnataka

Karnataka’s diverse flora and fauna face growing threats from poaching, habitat loss, pollution, human–wildlife conflict, and invasive species. Poaching has severely impacted the breeding of olive ridley turtles and otters along riverbanks, while tigers continue to face danger from illegal hunting. Valuable trees like sandalwood, known for its fragrance, and teakwood, prized for furniture, are also targets of forest poaching. Additionally, dam construction and deforestation have disrupted aquatic ecosystems and displaced forest-dependent species, while industrial and human waste have polluted rivers, harming aquatic life.

To counter these challenges, several conservation initiatives are underway, primarily led by the Karnataka Forest Department and various voluntary organizations. Efforts include relocating human settlements outside protected areas to reduce conflicts, using satellite technology to detect and control forest fires, and employing radio tracking and remote camera sampling to monitor wildlife populations. Wireless networks have been set up to aid field communication and anti-poaching operations. Moreover, conservation awards have been introduced to recognize and motivate dedicated forest and wildlife staff across the state.
