Explanations:The North-eastern region of India is renowned for its rich biodiversity, particularly in terms of flora. This region is home to a significant percentage of India's orchid species, making it a hotspot for orchid diversity. Orchids are a family of flowering plants that are known for their beautiful and intricate flowers. They are found in a wide variety of habitats, from tropical rainforests to temperate regions, and are particularly abundant in the North-eastern states of India.
The North-eastern region of India comprises eight states: Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, and Tripura. These states are characterized by their diverse topography, ranging from high mountains to dense forests, which provides a wide range of habitats for various plant species, including orchids. The region's unique geographical features, coupled with its tropical and subtropical climate, create an ideal environment for the growth and proliferation of orchids.
Orchids are not only important for their aesthetic value but also for their ecological and economic significance. They play a crucial role in the ecosystem by providing nectar to pollinators and serving as a food source for various insects and animals. Additionally, orchids are used in traditional medicine and have commercial value in the horticulture industry.
It is important to note that while the North-eastern region is known for its orchid diversity, it is also rich in other types of flora and fauna. However, the question specifically asks for a percentage of India's flora found in the North-eastern region, and orchids are the most prominent and well-known flora in this context.
Understanding the biodiversity of the North-eastern region is essential for conservation efforts and sustainable development. The region's unique flora, including orchids, contributes significantly to India's overall biodiversity and requires protection to ensure its preservation for future generations.
