Conservation Strategies
In-situ methods including biosphere reserves and hotspots, and ex-situ methods such as seed banks. (Biology › Biodiversity and Conservation, NEET UG syllabus.)
What is Conservation Strategies?
The conservation of ecosystems and natural habitats and the maintenance and recovery of viable populations of species in their natural surroundings.
Key points
- Differentiate between in-situ and ex-situ conservation strategies.
- Identify and provide examples of various in-situ conservation methods.
- Identify and provide examples of various ex-situ conservation methods.
- Explain the significance of biodiversity hotspots in conservation efforts.
Common exam trap
Confusing in-situ and ex-situ examples (e.g., calling a zoo in-situ).
Definitions
- Term
In-situ Conservation
- Meaning
The conservation of ecosystems and natural habitats and the maintenance and recovery of viable populations of species in their natural surroundings.
- Term
Ex-situ Conservation
- Meaning
The conservation of components of biological diversity outside their natural habitats.
- Term
Biodiversity Hotspots
- Meaning
Biogeographic regions with significant levels of biodiversity that are threatened by human habitation. They are characterized by high endemism and significant habitat loss.
- Term
Endemism
- Meaning
The ecological state of a species being unique to a defined geographic location, such as an island, nation, country or other defined zone, or habitat type.
- Term
Cryopreservation
- Meaning
A process where cells or tissues are preserved by cooling to very low temperatures, typically -196°C, using liquid nitrogen, to maintain their viability for long periods.
Learning objectives
Differentiate between in-situ and ex-situ conservation strategies.
Identify and provide examples of various in-situ conservation methods.
Identify and provide examples of various ex-situ conservation methods.
Explain the significance of biodiversity hotspots in conservation efforts.
Understand the role of different conservation approaches in preserving biodiversity.
Recognize the importance of both strategies working in conjunction.
Prerequisites
Basic understanding of biodiversity and its levels (genetic, species, ecosystem).
Knowledge of the causes and threats to biodiversity loss (e.g., habitat loss, over-exploitation, alien species invasion, co-extinctions).
Familiarity with ecological concepts like endemism and ecosystem services.
Common mistakes
Confusing in-situ and ex-situ examples (e.g., calling a zoo in-situ).
Forgetting the specific examples for each type of conservation.
Not knowing the number or names of biodiversity hotspots in India.
Misunderstanding the primary purpose of each conservation method (e.g., thinking a National Park is primarily for tourism).
Mixing up National Parks and Wildlife Sanctuaries (National Parks have stricter regulations).
