Biogeographic Province is a biotic subdivision of biogeographic realms that are further subdivided into ecoregions that are classified based on their biomes or habitat types. The provinces are large areas of the Earth's surface where organisms have evolved in relative isolation over long periods, separated from one another by geographic features such as oceans, broad deserts, or high mountain ranges that act as migration barriers. In this article, we will discuss Biogeographic Provinces which will be helpful for UPSC exam preparation.

Identification of Biogeographic Zones

• Zone 1 - Trans-Himalayan
• Zone 2 - Himalayas
• Zone 3 - The Indian Desert
• Zone 4 - Semi-Arid Areas
• Zone 5 - Western Ghats
• Zone 6 - Deccan Plateau
• Zone 7 - Gangetic Plain
• Zone 8 - North-East India
• Zone 9 - Islands
• Zone 10 - Coasts

Biogeographic Provinces

A biogeographic province is an eco-systematic or biotic subdivision of realms. India is divided into 25 biogeographic provinces.

Biogeographic Provinces of India

Conclusion

The division of India based on biogeographic characteristics is known as biogeographic classification. Rodgers and Panwar (1988) created a biogeographic classification of India, describing 10 biogeographic zones that were further subdivided into 25 biogeographic provinces. Altitude, moisture, topography, rainfall, and other factors were used in the classification. In India, biogeographic zones were used to plan wildlife protected areas.

GS Mains Questions and Model Answers

Q1: Discuss the significance of biogeographic provinces in understanding India's biodiversity.

Answer: Biogeographic provinces are crucial for understanding India's biodiversity as they categorize the country into regions with distinct ecosystems, which are shaped by factors such as climate, topography, and soil. These provinces help scientists study the distribution of species and ecosystems, providing insights into the origin, migration, and adaptation of various species. Furthermore, understanding biogeographic provinces aids in effective conservation planning by identifying key regions that require protection to maintain biodiversity. Each province contains unique species, and preserving their ecosystems is vital for sustaining India's natural heritage and mitigating the impacts of climate change.

Q2: How do human activities affect the biogeographic provinces of India?

Answer: Human activities have profound impacts on the biogeographic provinces of India, primarily through deforestation, agriculture, and urbanization. Deforestation leads to habitat destruction, reducing biodiversity and altering the natural balance of ecosystems. Intensive farming and the use of chemical fertilizers and pesticides can degrade soil health and affect the flora and fauna of these provinces. Urbanization and industrialization further disrupt natural habitats, leading to fragmentation of ecosystems. Overexploitation of resources such as water and minerals can also affect the ecological integrity of these provinces. Sustainable land-use practices and conservation efforts are essential to minimize the negative effects of human activity.

Q3: Evaluate the role of biogeographic provinces in the context of wildlife conservation in India.

Answer: Biogeographic provinces play a critical role in wildlife conservation in India by providing a framework for identifying regions that require protection. Each province hosts unique species adapted to its specific climatic and ecological conditions. Protecting these regions helps maintain biodiversity by preserving species and ecosystems in their natural habitats. By understanding the ecological boundaries of these provinces, conservationists can prioritize the establishment of protected areas like national parks, wildlife sanctuaries, and biosphere reserves. Additionally, the concept of biogeographic provinces helps in creating wildlife corridors to maintain genetic diversity and enable species to migrate freely, ensuring long-term conservation success.

Previous Year Questions on Biogeographic Provinces

1. UPSC CSE Prelims 2020:

Question: How many biogeographic provinces are there in India?

A) 8
B) 10
C) 12
D) 15

Answer: (B)

Explanation: India is divided into 10 biogeographic provinces, each with unique ecological features and biodiversity.

2. UPSC CSE Mains 2021 (GS Paper 3):

Question: "Discuss the relationship between biogeographic provinces and conservation strategies in India."

Answer: Biogeographic provinces help in understanding the distribution of ecosystems and species in India, which is essential for developing targeted conservation strategies. By studying the unique ecological characteristics of each province, conservationists can identify regions that are critical for preserving biodiversity. These strategies include establishing protected areas, creating wildlife corridors, and promoting sustainable agricultural practices. Effective conservation planning based on biogeographic provinces helps mitigate the effects of climate change and human encroachment on ecosystems.
