Question

Which of these is an in-situ method of conservation?
A. National park
B. Botanical garden
C. Tissue culture
D. Genetic engineering

Answer 1

In-situ conservation is the conservation that helps in the protection and the management of important components of the biological diversity through the network of the protected areas. This conservation is the conservation of the genetic resources in natural populations of plants or animal species as the forest genetic resources, in natural populations of the tree and animal species.

Complete answer: The in-situ conservation is called on-situ conservation, which means the conservation of genetic resources in the form of natural populations by establishing biosphere reserves such as the national parks and the sanctuaries. This conservation involves the maintenance of genetic variation at the location where it is encountered, either in the wild or in the traditional farming systems.
The three main in situ techniques may be broadly defined as the genetic reserve, the on-farm, and the home garden conservation.
-The genetic reserve conservation of the wild species involves the location, the designation, the management, and monitoring of the genetic diversity in a particular, natural location.
-This is one of the most appropriate techniques for the bulk of wild species because it can, when the management regime is minimal, be relatively inexpensive.
-When dealing with the plants, the object is for the reserve to contain the minimum number of the individuals that can maintain genetic diversity within the species; too few and genetic diversity will decline over time, too many and the resources may be wasted in managing the large population.
Practices like horticulture and floriculture also preserve plants in a natural habitat.
Therefore, the correct answer is Option A.

Note: The in-situ conservation offers several advantages when protecting endangered species from extinction. One of the major advantages of this conservation includes the retaining of the natural habitat preventing eventual loss and also ensures it remains available for other endangered species.
