It defines key terms related to wildlife, such as 'animal', 'hunting', and 'national park', and outlines the responsibilities of various authorities like the chief wildlife warden and wildlife advisory board. The act encompasses regulations on capturing, trading, and conserving wildlife, emphasizing the importance of preserving biodiversity.
