Step 1: Definition.
Biodiversity conservation refers to the protection, maintenance, and sustainable management of ecosystems, species, and genetic resources to prevent their loss.
Step 2: Strategies for biodiversity conservation. There are two major approaches: \[\begin{array}{rl} 1. & \text{In-situ conservation (On-site): Protects species in their natural habitat.} \\ \bullet & \text{Biosphere reserves: Large areas conserving ecosystems (e.g., Nilgiri, Sundarbans).} \\ \bullet & \text{National parks: Strict protection of wildlife (e.g., Kaziranga, Jim Corbett).} \\ \bullet & \text{Wildlife sanctuaries: Protection of particular species with limited human activities (e.g., Bharatpur Bird Sanctuary).} \\ \bullet & \text{Sacred groves: Forest patches protected by local communities (e.g., Meghalaya).} \\ 2. & \text{Ex-situ conservation (Off-site): Protects species outside their natural habitats.} \\ \bullet & \text{Botanical gardens and zoological parks.} \\ \bullet & \text{Gene banks: Preservation of genetic material (seed banks, cryopreservation, tissue culture).} \\ \bullet & \text{Captive breeding and reintroduction programmes.} \\ \end{array}\]
Step 3: Legal and global efforts.
\[\begin{array}{rl} \bullet & \text{Convention on Biological Diversity (CBD, 1992).} \\ \bullet & \text{Indian Wildlife Protection Act (1972).} \\ \bullet & \text{Project Tiger and Project Elephant in India.} \\ \end{array}\]
Step 4: Conclusion.
A combination of in-situ and ex-situ strategies, along with awareness and legislation, is essential for sustainable conservation of biodiversity.
