Which of the following is not an example of 'ex situ' conservation of biodiversity?

Appeared in: KPSC Staff Nurse - 2016

Explanation

A national park is a form of in-situ conservation, which means protecting species within their natural habitat.
The question asks to identify the method that is NOT ex-situ (off-site) conservation.
In-situ conservation focuses on protecting entire ecosystems and biodiversity hotspots.
Examples of in-situ conservation include National Parks, Wildlife Sanctuaries, and Biosphere Reserves.

Option B: This is a classic example of ex-situ conservation, as it involves storing seeds away from their native environment in controlled conditions.
Option C: This is an ex-situ method where animals are kept and bred outside their natural habitats.
Option D: This is an ex-situ method where a wide variety of plants, often endangered, are cultivated outside their natural ecosystem.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Difference between in-situ and ex-situ conservation methods as background academic context rather than a clinical decision trigger.
Understanding different conservation strategies is relevant in environmental health, a key component of community health nursing. The health of an ecosystem directly impacts human health through factors like clean air, water, and the prevention of zoonotic diseases.
Both methods are complementary. Ex-situ conservation acts as an insurance policy for species that cannot be safely maintained in their natural habitat due to threats like poaching, habitat loss, or disease.
What if? If a species becomes extinct in the wild but still exists in a zoological park, the only hope for its reintroduction into a restored habitat comes from ex-situ conservation efforts, highlighting its critical role as a last resort.

How to Approach the Question

First, identify the negative keyword 'not' in the question. This means you are looking for the option that does not fit the specified category.
Next, define the key term 'ex situ conservation'. It means 'off-site' or conservation outside the natural habitat.
Evaluate each option against this definition.
A 'Seed bank' is off-site storage. A 'Zoological park' is an off-site animal facility. A 'Botanical garden' is an off-site plant collection. These are all ex-situ.
A 'National park' protects an entire area in its natural state. This is 'in-situ' or 'on-site' conservation.
Therefore, the national park is the one that is NOT an example of ex-situ conservation.

Concept Tested & Keywords

Concept Tested: Difference between in-situ and ex-situ conservation methods.
Stem keywords: ex situ conservation, biodiversity
Lead-in keywords: not an example
Negative lead-in flag: The question asks to identify the option that is NOT an example of ex situ conservation.
