Arunachal Pradesh’s diverse climate is a result of its unique geographical features, ranging from the lowland foothills to the high peaks of the eastern Himalayas. The state’s climatic conditions also influence its rich biodiversity, with various types of flora and fauna found across different regions. The vast array of climates makes Arunachal Pradesh a region of immense ecological and environmental significance.
