Chapter Overview

About 41% of Chhattisgarh is under forest cover (ISFR 2023), yet its state animal, the wild water buffalo (वन भैंसा), survives in the wild in only a few dozen animals at most. The state also shows how conservation works today. It protects animals where they live (Udanti-Sitanadi, the new Guru Ghasidas-Tamor Pingla Tiger Reserve), breeds them in enclosures when wild numbers collapse (the Barnawapara wild buffalo enclosure), and stores the genes of thousands of traditional rice varieties in a gene bank at Raipur. This chapter is the conservation science of that story: why biodiversity is worth saving, where it is most at risk, and the tools and laws India uses to save it.

How this chapter fits with the others

Concepts (definition, α/β/γ diversity, biogeographic zones, threats, IUCN categories) are covered in depth in Biodiversity under Geography. This chapter recaps them briefly and focuses on conservation.
Chhattisgarh’s own parks, sanctuaries and reserves are covered in Forests and Wildlife of Chhattisgarh. This chapter uses them only as examples.
Treaties (Ramsar, CITES, CBD) are in Environment and Ecology. This chapter covers how India implements them.

What You’ll Learn

By the end of this chapter, you’ll be able to:

Explain the three levels of biodiversity (जैव विविधता) and why each needs its own conservation strategy
Define a biodiversity hotspot, state its two criteria and name India’s four hotspots
Distinguish in-situ (स्व-स्थाने) from ex-situ (पर-स्थाने) conservation, with Indian and Chhattisgarh examples
Describe India’s protected-area network: national parks, sanctuaries, conservation and community reserves, tiger and elephant reserves, biosphere reserves and Ramsar sites, with dated counts
Recall the main provisions of the Wild Life (Protection) Act, 1972 (as amended in 2022) and the Biological Diversity Act, 2002 (as amended in 2023)
Write a balanced Mains answer on conservation versus development and community rights

Prerequisites

Environment and Ecology: ecosystems, food chains and the concept of biodiversity
Forests and Wildlife of Chhattisgarh: the state’s protected areas, used as examples throughout
Biology and Health: cells and genes, which help with genetic diversity and gene banks

Where It Is Asked

Exam Focus

Prelims P-I (India GS): hotspot criteria and India’s four hotspots; in-situ vs ex-situ examples; PA categories and which law creates them; Schedules of the WPA after 2022; NBA–SBB–BMC structure; dated counts of tiger reserves, biosphere reserves and Ramsar sites. Statement-based questions often hide one wrong number or one swapped law.
Mains P-IV GS-II (Applied Science, environment): short notes (biosphere reserve, gene bank, BMC) and 150–200-word answers on threats, conservation strategies, community participation and conservation versus development.
Chhattisgarh angle (useful in both papers): wild buffalo conservation, Guru Ghasidas-Tamor Pingla (India’s 56th tiger reserve), Achanakmar-Amarkantak Biosphere Reserve, Kopra Ramsar site, the rice gene bank at Raipur, Hasdeo Arand and Lemru.
