Flora and Fauna: Notes और MCQ Practice

आसान भाषा में

Flora का मतलब किसी specific region में पाए जाने वाले सभी Plants (वनस्पति) हैं, जबकि Fauna का मतलब उस क्षेत्र के Animals (जीव-जंतु) से है। RRB NTPC में इससे सीधे सवाल Biodiversity Hotspots, Protected Areas (National Parks, Sanctuaries) और IUCN Red List status से पूछे जाते हैं।

Important Key Facts & Rules

• Global Share: India दुनिया के 17 Mega-biodiverse देशों में शामिल है और globally लगभग 7% - 8% recorded species को host करता है।
• 4 Biodiversity Hotspots in India: 1. Himalayas, 2. Western Ghats, 3. Indo-Burma, 4. Sundaland (Nicobar Islands शामिल)।
• IUCN Red List Order: Extinct (EX) → Extinct in the Wild (EW) → Critically Endangered (CR) → Endangered (EN) → Vulnerable (VU)।
• Biosphere Reserve Zones: Core Zone (strictly protected, no human activity) → Buffer Zone (research allowed) → Transition Zone (human settlements allowed)।
• Key Wildlife Acts: Wildlife Protection Act = 1972, Project Tiger = 1973, Project Elephant = 1992।

Quick Tricks (याद रखने के फंडे)

1. Flora vs Fauna Confusion: Flora = Flower (यानी केवल Plants), और Fauna = Fawn (हिरण का बच्चा, यानी Animals)।
2. Hotspots Shortcut "WHIS": Western Ghats, Himalayas, Indo-Burma, Sundaland।

Common Mistakes (Exam में इनसे बचें!)

1. National Park vs Wildlife Sanctuary: National Parks में human activities और grazing completely prohibited होती है, जबकि Wildlife Sanctuaries में limited human rights और grazing permit के साथ allowed हो सकती है।
2. Endemic vs Invasive Species: Endemic species केवल एक specific geographical area में naturally मिलती हैं (जैसे Western Ghats का Lion-tailed Macaque), जबकि Invasive/Exotic species बाहर से लाई जाती हैं और local flora/fauna को नुकसान पहुंचाती हैं।

Flora and Fauna: Comprehensive Study Notes for RRB NTPC

1. Concept (Simple Explanation)

In ecology and geography:

• Flora refers to the entire plant life naturally occurring in a particular region or time period (e.g., Sal, Teak, Mangroves, Rhododendrons).
• Fauna refers to the entire animal life characteristic of a specific region or environment (e.g., Royal Bengal Tiger, Snow Leopard, Sangai).
• Biodiversity represents the variety of plant and animal life in a particular habitat.

Conservation Approaches

To protect threatened flora and fauna, conservation is divided into two primary methods:

1. In-situ Conservation (On-site): Protecting species within their natural habitats.

• Examples: National Parks, Wildlife Sanctuaries, Biosphere Reserves, Reserved Forests, Sacred Groves.

1. Ex-situ Conservation (Off-site): Protecting species outside their natural habitats in controlled environments.

• Examples: Botanical Gardens, Zoological Parks (Zoos), Gene Banks, Seed Banks, Cryopreservation centers.

Key Protection Designations in India

• National Park (NP): Highest level of protection. No human activity, private land holding, or cattle grazing is permitted. Created by notification under the Wildlife (Protection) Act, 1972.
• Wildlife Sanctuary (WLS): Focuses on protecting particular species. Certain limited human activities such as regulated cattle grazing or timber collection may be allowed.
• Biosphere Reserve (BR): Large protected area meant for conservation, research, and sustainable development. Divided into three zones: Core (strictly protected), Buffer (limited research and tourism), and Transition (human settlement and agriculture allowed).

2. Important Facts, Rules, and Data

• Total Biosphere Reserves in India: 18 (out of which 12 are part of the UNESCO World Network of Biosphere Reserves under the MAB - Man and the Biosphere Programme).

Biodiversity Hotspots

To qualify as a hotspot, a region must contain at least 1,500 species of vascular plants as endemics and have lost at least 70% of its primary vegetation. India covers 4 major global biodiversity hotspots:

1. The Himalayas (entire Indian Himalayan region)
2. Indo-Burma (North-East India except Assam)
3. Western Ghats and Sri Lanka
4. Sundaland (includes Nicobar group of islands)

Important Endemic / Threatened Species and their Habitats

• One-horned Rhinoceros: Kaziranga National Park (Assam), Manas National Park (Assam), Jaldapara National Park (West Bengal).
• Asiatic Lion: Gir National Park (Gujarat) - only wild habitat in the world.
• Lion-tailed Macaque: Endemic to the evergreen forests of the Western Ghats (Silent Valley National Park, Kerala).
• Hangul (Kashmir Stag): Dachigam National Park (Jammu & Kashmir).
• Olive Ridley Sea Turtle: Gahirmatha Marine Sanctuary / Rushikulya rookery (Odisha).

4. Shortcuts and Tricks

1. In-situ vs. Ex-situ Root Word Trick

• IN-situ = IN the site (natural home): National Park, Wildlife Sanctuary, Biosphere Reserve.
• EX-situ = EXited the site (away from natural home): Zoo, Seed bank, Botanical garden, Aquarium.

2. Chronology Memory Peg (72-73-86-92)

Remember the 4 big environment milestones as an ascending sequence:

• 1972 -> Wildlife Protection Act (W comes first)
• 1973 -> Tiger Project (T comes right after W)
• 1986 -> Environment Protection Act (E comes later)
• 1992 -> Elephant Project (Elephant is biggest, comes last)

3. Biosphere Reserve Zones: "C-B-T" Inside-Out

• C = Core (Center: Zero human interference)
• B = Buffer (Middle: Controlled research, education, ecotourism)
• T = Transition (Outer boundary: Human settlements, cropping, forestry)

4. Mnemonic for Rare Animal-Park Pairs

• Hangul in Dachigam -> "Hang the Door"
• Sangai in Keibul Lamjao (Manipur) -> "Sangai Keeps Moving (dancing)"
• Asiatic Lion in Gir -> "Always Gir"

5. Common Mistakes to Avoid

1. Confusing National Park with Wildlife Sanctuary:

• Mistake: Assuming people can live or graze cattle in a National Park.
• Correction: Grazing and private rights are strictly prohibited in National Parks, but may be selectively allowed in Sanctuaries.

1. Confusing Jim Corbett National Park with Hailey National Park:

• Mistake: Treating them as two different parks.
• Correction: Hailey National Park was renamed Ramganga National Park in 1954, and then Jim Corbett National Park in 1956. It is India's first national park (1936).

1. Mixing Up Year of Wildlife Act (1972) and Project Tiger (1973):

• Mistake: Answering 1973 for the Wildlife Protection Act.
• Correction: The Act was passed in 1972; Project Tiger was started the following year in 1973.

1. Classifying Botanical Gardens as In-situ:

• Mistake: Thinking that because plants grow in soil in a botanical garden, it is in-situ.
• Correction: The plants were brought from elsewhere and cultivated in an artificial, managed environment; hence, it is strictly Ex-situ.
