Biodiversity Conservation Questions in English

(B) The $IUCN$ ($International$ $Union$ $for$ $Conservation$ $of$ $Nature$) is the organization responsible for maintaining the $Red$ $Data$ $Book$ or $Red$ $List$.
This list provides a comprehensive inventory of the global conservation status of biological species,focusing on those that are threatened or endangered.
$CSIR$ stands for $Council$ of $Scientific$ and $Industrial$ $Research$,$NEERI$ stands for $National$ $Environmental$ $Engineering$ $Research$ $Institute$,and $WLS$ stands for $Wildlife$ $Sanctuary$.

(C) The World Summit on Sustainable Development $(2002)$ was held in Johannesburg,South Africa. In this summit,$190$ countries pledged their commitment to achieve by $2010$ a significant reduction in the current rate of biodiversity loss at global,regional,and local levels.

(A) Cryopreservation is a technique used for the long-term conservation of plant genetic resources. In this process,seeds or other plant materials are stored in liquid nitrogen at a temperature of $-196^{\circ} C$. At this extremely low temperature,all metabolic activities of the seeds are suspended,allowing them to be stored indefinitely without losing their viability.

(A) Statement $I$ is correct. Sacred groves are forest patches that are culturally protected by local communities,where all trees and wildlife are given total protection.
Statement $II$ is also correct. In India,ecologically unique and biodiversity-rich regions are legally protected as biosphere reserves,national parks,and sanctuaries. However,in Meghalaya,the sacred groves are the last refuges for a large number of rare and threatened plants and animals. Since both statements are factually accurate,the correct option is $A$.

(D) In situ conservation involves the protection of plants and animals within their natural habitats.
$A$,$B$,and $C$ (National Parks,Biosphere Reserves,and Wildlife Sanctuaries) are examples of in situ conservation.
$D$ (Zoological parks) is an example of ex situ conservation,where organisms are kept in a protected environment outside their natural habitat for care and breeding.
Therefore,the correct answer is $D$.

(C) is the correct answer.
Advanced $ex \, situ$ conservation involves the preservation of genetic resources of species away from their natural habitat or area of origin.
This strategy is designed to conserve a larger amount of genetic material within a smaller physical space.
The various methods through which $ex \, situ$ conservation is achieved include:
$1$. Cryopreservation (storage of gametes or embryos at extremely low temperatures).
$2$. Plant tissue culture (propagation of plants from cells or tissues).
$3$. Seed banks (long-term storage of seeds).
$4$. $In \, vitro$ fertilisation (fertilisation outside the living organism).
Therefore, all the listed statements $(I, II, III, IV)$ are correct.

(A) The correct answer is $A$.
The historic convention related to the conservation of biological diversity is known as the Earth Summit.
The Convention on Biological Diversity $(CBD)$ was held in Rio de Janeiro in $1992$.
It has three main goals:
$1$. The conservation of biological diversity.
$2$. The sustainable use of its components.
$3$. The fair and equitable sharing of benefits arising from genetic resources.

(D) The correct option is $D$.
Biodiversity hotspots are biogeographic regions characterized by high levels of biodiversity and significant threats of habitat destruction.
The concept was introduced by $Dr. Norman Myers$ in $1988$.
To qualify as a biodiversity hotspot, an area must meet two strict criteria:
$1$. It must contain at least $1,500$ species of vascular plants as endemics (i.e., species found nowhere else on Earth).
$2$. It must have lost at least $70\%$ of its primary native vegetation.
Therefore, a large number of exotic (non-native) species is not a defining characteristic of a biodiversity hotspot; rather, the focus is on the high density of endemic species and the urgent need for conservation due to habitat loss.

(C) The correct answer is $C$.
$Ex$ $situ$ conservation refers to the conservation of selected rare plants or animals in locations outside their natural habitats.
$Ex$ $situ$ conservation methods include offsite collections such as botanical gardens, zoological parks, seed banks, tissue culture, and cryopreservation.
Biosphere reserves are examples of $in$ $situ$ conservation, where the entire ecosystem is protected within its natural environment.

(A) $Project Dodo$ is not a real wildlife conservation initiative.
The dodo is an extinct species and has no current conservation project.
$Project Indian Bustard$,$Project Tiger$,and $Project Hangul$ are genuine conservation efforts in India aimed at protecting endangered species like the Indian bustard,tigers,and the Hangul deer.

(B) Kaziranga National Park.
Kaziranga National Park, located in Assam, India, is world-renowned for hosting two-thirds of the world's population of the one-horned rhinoceros, also known as the Indian rhinoceros $(Rhinoceros \text{ } unicornis)$.

(C) Botanical garden.
In situ conservation refers to the conservation of species within their natural habitats.
National parks,sanctuaries,and biosphere reserves are examples of in situ conservation areas.
Botanical gardens are examples of ex situ conservation,where plants are conserved outside their natural habitats.

(B) Biodiversity conservation is categorized based on how human beings derive benefits from nature. The categories include:
$(1)$ Narrowly utilitarian: derived from direct economic benefits like food,firewood,fiber,perfumes,industrial products,and medicinal drugs.
$(2)$ Broadly utilitarian: derived from ecosystem services like production of oxygen,pollination,and aesthetic pleasures.
$(3)$ Ethical: based on the belief that every species has an intrinsic value and we have a moral duty to care for their well-being.
Since oxygen production is an ecosystem service,it falls under the Broadly utilitarian category.

(B) In situ conservation involves protecting species within their natural habitats.
Examples include National Parks,Wildlife Sanctuaries,Biosphere Reserves,and Sacred Groves.
Ex situ conservation involves protecting species outside their natural habitats,such as in Seed Banks,Botanical Gardens,and Wildlife Safari Parks.
Therefore,Sacred Groves is an in situ conservation method.
Thus,option $(2)$ is correct.
