Which state is home to the Udanti Sitanadi Tiger Reserve that made headlines recently?

State of Chhattisgarh is home to the Udanti Sitanadi Tiger Reserve, which made headlines recently because of encroachment problems. The Gariaband district of Chhattisgarh is home to the tiger reserve. However, illegal encroachment into the reserve's buffer area has presented challenges. After a lengthy legal battle in which the court denied the encroachers' petition, the Chhattisgarh high court ordered the encroachers to be removed from the reserve. This action was justified by evidence, including ISRO satellite imagery demonstrating that, up until 2012, the encroached region was covered in dense forest. The problem has brought attention to the difficulties that India's wildlife reserves face from unlawful encroachment and the requirement for diligent conservation efforts.
