National Park:
- A National Park is an area set aside by a national government to protect the natural environment and the flora and fauna found within it.
- The primary objective of a National Park is to preserve the ecological integrity of the area and to provide a sanctuary for wildlife.
- In-situ conservation is a key aspect of National Parks, as they aim to protect the natural habitats and ecosystems in their original form.
- National Parks often have strict regulations and restrictions in place to ensure that the flora and fauna are not disturbed or harmed.

Biosphere Reserve:
- A Biosphere Reserve is a unique designation given to a specific area that is recognized internationally for its importance in terms of biodiversity conservation.
- Biosphere Reserves are intended to promote the conservation of ecosystems, genetic diversity, and sustainable development.
- They often encompass a variety of habitats, including forests, wetlands, mountains, and coastal areas, and are managed to balance conservation with sustainable use.
- In-situ conservation is a core component of Biosphere Reserves, as they aim to protect and sustain the natural ecosystems found within their boundaries.
- Biosphere Reserves also focus on research, education, and community involvement to promote conservation efforts.

Botanical Garden:
- A Botanical Garden is a curated collection of plants, both native and exotic, for scientific, educational, and ornamental purposes.
- While Botanical Gardens play an important role in ex-situ conservation, as they maintain living collections of plants outside their natural habitats, they can also contribute to in-situ conservation efforts.
- Many Botanical Gardens have sections dedicated to native plant species, where they are grown and displayed in their natural ecological settings.
- These gardens often serve as educational platforms to raise awareness about the importance of conserving local flora and its role in maintaining ecosystems.

Wildlife Sanctuary:
- A Wildlife Sanctuary is a protected area that is established to conserve wildlife and their habitats.
- The primary focus of a Wildlife Sanctuary is the protection and conservation of wildlife species, including both flora and fauna.
- In-situ conservation is a key objective of Wildlife Sanctuaries, as they aim to preserve the natural habitats and ecosystems that support the wildlife populations.
- Wildlife Sanctuaries often have strict regulations in place to restrict human activities and minimize disturbances to the wildlife.

Botanical Garden is not a site for in-situ method of conservation of flora:
- While Botanical Gardens can contribute to in-situ conservation efforts through the display and cultivation of native plant species, their primary role is in ex-situ conservation.
- Botanical Gardens typically maintain collections of plants outside their natural habitats, often for research, education, and ornamental purposes.
- They may have conservation programs in place, but their main function is to provide a controlled environment for preserving plant species and studying their biology and ecology.
- In contrast, National Parks, Biosphere Reserves, and Wildlife Sanctuaries focus on the conservation of flora and fauna in their natural habitats, making them more suitable for in-situ conservation efforts.
