MediumMCQ
Assertion : $A$ sanctuary is formed for the conservation of animals only.
Reason : Restricted human activities are allowed in sanctuaries.
A
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
B
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
C
If the Assertion is correct but Reason is incorrect.
D
If both the Assertion and Reason are incorrect.

Solution

(B) The Assertion is correct because a wildlife sanctuary is a protected area specifically designated for the conservation of wild animals.
The Reason is also correct because,unlike national parks,sanctuaries allow certain human activities such as the harvesting of timber,collection of minor forest products,and private ownership rights,provided these activities do not adversely affect the wildlife.
However,the Reason does not explain why a sanctuary is formed for animals only; it merely describes the management policy of the sanctuary. Therefore,the Reason is not the correct explanation of the Assertion.
111
Medium
What are sacred groves? What is their role in conservation?

Solution

(N/A) Sacred groves are tracts of forest which are regenerated around places of worship.
Sacred groves are found in regions like Rajasthan,the Western Ghats of Karnataka and Maharashtra,Meghalaya,and Madhya Pradesh.
Their role in conservation is significant as they help in the protection of many rare,threatened,and endemic species of plants and animals found in a specific area.
The process of deforestation is strictly prohibited in these regions by local tribal communities.
Consequently,sacred groves serve as vital reservoirs of biodiversity and are considered rich areas for conservation.
112
Advanced
Can you think of a situation where we deliberately want to make a species extinct? How would you justify it?

Solution

(N/A) Yes,there are various kinds of parasites and disease-causing microbes that we deliberately want to eradicate from the Earth. Since these microorganisms are harmful to human beings,scientists are working hard to fight against them. Scientists have been able to eliminate the smallpox virus from the world through the use of vaccinations. This shows that humans deliberately want to make these species extinct. Several other eradication programs,such as polio and Hepatitis $B$ vaccinations,are aimed at eliminating these disease-causing microbes.
113
Medium
State the reasons for the conservation of biodiversity.

Solution

(A) The reasons for conserving biodiversity can be grouped into three categories:
$(a)$ Narrowly utilitarian,$(b)$ Broadly utilitarian,and $(c)$ Ethical.
$(a)$ Narrowly utilitarian: These reasons are obvious as humans derive countless direct economic benefits from nature. $(i)$ Food (cereals,pulses,fruits),firewood,fiber,construction material,industrial products (tannins,lubricants,dyes,resins,perfumes),and products of medicinal importance. $(ii)$ More than $25,000$ species of plants contribute to the traditional medicines used by native peoples around the world. At least $25$ percent of all drugs are currently sold across the market worldwide are derived from plants.
$(b)$ Broadly utilitarian: $(i)$ Biodiversity plays a major role in many ecosystem services that nature provides. $(ii)$ The Amazon forest is estimated to produce through photosynthesis $20$ percent of the total oxygen in the earth's atmosphere. $(iii)$ Pollination,without which plants cannot give us fruits or seeds,is another service that ecosystems provide through pollinators like bees,bumblebees,birds,and bats. $(iv)$ There are other intangible benefits that we derive from nature,such as aesthetic pleasures of walking through thick woods,watching spring flowers in full bloom,or waking up to a bulbul's song in the morning.
$(c)$ Ethical: $(i)$ We share this planet with millions of plant,animal,and microbe species. $(ii)$ Philosophically or spiritually,we need to realize that every species has an intrinsic value,even if it may not be of current or any economic value to us. $(iii)$ We have a moral duty to care for their well-being and pass on our biological legacy in good order to future generations.
114
Easy
State the approaches for the conservation of biodiversity.

Solution

(N/A) There are two main approaches for the conservation of biodiversity:
$(a)$ $In-situ$ conservation
$(b)$ $Ex-situ$ conservation
When we conserve and protect the whole ecosystem,its biodiversity at all levels is protected. For example,to save the tiger,we must save the entire forest; this is called $In-situ$ conservation.
In situations where an animal or plant is endangered and needs urgent measures to save it from extinction,$Ex-situ$ conservation is the appropriate approach.
115
Easy
Describe various methods used in 'In situ conservation'.

Solution

(N/A) In situ conservation,also known as 'on-site conservation',involves protecting species within their natural habitats. The primary methods include:
$1$. National Parks: These are strictly protected areas where human activities like grazing,cultivation,and forestry are prohibited to preserve the ecosystem.
$2$. Wildlife Sanctuaries: These areas allow limited human activities such as harvesting of timber or collection of minor forest products,provided they do not interfere with the conservation of wildlife.
$3$. Biosphere Reserves: These are large,multi-purpose protected areas designed to conserve biodiversity while promoting sustainable development. They are divided into three zones: the core zone (no human activity),the buffer zone (limited research and education),and the transition zone (human settlements and sustainable resource use).
$4$. Sacred Groves: These are forest patches protected by local communities based on cultural or religious beliefs,serving as a refuge for rare and threatened plant and animal species.
116
Medium
Describe National Park and Sanctuary.

Solution

(N/A) $National Park$ is a protected area established by the government to conserve wildlife and its environment. It is strictly protected, and human activities like grazing, cultivation, and private ownership are prohibited. It focuses on the conservation of the entire ecosystem.
$Sanctuary$ is a protected area where animals are protected from hunting and poaching. Limited human activities such as the collection of timber, medicinal plants, and firewood are permitted, provided they do not harm the wildlife. It is often established for the protection of specific species.
117
Medium
Write an explanatory note on Ex situ conservation.

Solution

(N/A) Ex situ (off-site) conservation involves placing threatened animals and plants in special care units for their protection.
Ex situ conservation includes off-site collections and gene banks.
Off-site Collections: These are live collections of wild and domestic species in botanical gardens,zoological parks,wildlife safari parks,etc.
India has $355$ parks where animals that have become extinct in the wild are maintained,and $35$ botanical gardens where plant species are protected.
Gene Banks: These are places where gametes are protected and maintained by stocking viable seeds (seed banks),tissue culture,and frozen germplasm with a full range of genetic variability. These include:
$(a)$ Seed Bank: Storing different genetic strains of commercially important plants as seeds is one of the most widespread and valuable ex situ conservation strategies.
$(b)$ Tissue Culture: Plant tissue culture is widely used to produce clones of a plant through a method known as micropropagation. This method is useful for maintaining a large number of genotypes in a small area,rapid multiplication of endangered species,and hybrid rescue (e.g.,banana and potato).
$(c)$ Cryopreservation: This is a method of in vitro conservation in liquid $N_2$ at a temperature of $-196^{\circ}C$ in a controlled-rate freezer for vegetatively propagated crops and storing other biological material.
118
Easy
Describe the international initiatives for the conservation of biodiversity.

Solution

(N/A) $\rightarrow$ Biodiversity conservation is a collective responsibility of all nations.
$1$. The Convention on Biological Diversity (The Earth Summit) held in Rio de Janeiro in $1992$ called upon all nations to take initiatives for biodiversity conservation.
$2$. $A$ follow-up World Summit on Sustainable Development was held in $2002$ in Johannesburg,South Africa.
$3$. In this summit,$190$ countries made commitments to significantly reduce the current rate of biodiversity loss at global,regional,and local levels by $2010$.
$4$. In $2012$,the United Nations Conference on Sustainable Development was held again in Rio,which is referred to as Rio $+ 20$ or the Rio Earth Summit $2012$.

121
Easy
Give scientific reasons: Wildlife acts as our gene bank.

Solution

(N/A) Wildlife species,including wild plants,animals,and microorganisms,serve as a vast reservoir of genetic diversity. These wild relatives contain valuable genes that can be transferred to our domesticated crops and livestock through modern biotechnological techniques. This process helps in developing high-yielding,disease-resistant,and climate-resilient varieties. Thus,wildlife acts as a gene bank,providing the raw material for genetic improvement and the evolution of new,beneficial traits.
122
Medium
Give scientific reasons: Under the wildlife conservation program,endangered species should be given the highest priority.

Solution

(N/A) Endangered species are those whose population has declined to a critical level and whose natural habitats have been severely affected. Therefore,it is essential to prioritize endangered species,including rare and vulnerable species,to prevent their extinction and maintain ecological balance.
123

Define/Explain: Sanctuary.
A
An area where human activities like harvesting timber,collection of minor forest products,and private ownership rights are allowed.
B
$A$ protected area where only scientific research is permitted.
C
$A$ region where the entire ecosystem is protected from all human interference.
D
An area where only endangered species are kept in captivity.

Solution

(A) sanctuary is a protected area,such as a national park or a wildlife refuge,where human activities are limited to ensure the conservation of wildlife and their habitats.
In a sanctuary,certain human activities like harvesting timber,collection of minor forest products,and private ownership rights are allowed,provided they do not interfere with the well-being of the animals.
It serves as a safe haven for wild animals to live,breed,and thrive without the threat of hunting or poaching.
126
Easy
Explain how the protection of biodiversity hotspots alone can reduce up to $30 \%$ of the current rate of species extinction.

Solution

(N/A) Biodiversity hotspots are regions with very high levels of species richness and high degree of endemism.
Although all the biodiversity hotspots put together cover less than $2 \%$ of the Earth's land area,the number of species they collectively harbor is extremely high.
By strictly protecting these hotspots,we can prevent the loss of a vast number of endemic species.
Therefore,strict protection of these hotspots could reduce the ongoing mass extinctions by almost $30 \%$.

Explain how biodiversity is important for humans and explain what is conservation?

Solution

(N/A) Conservation of biodiversity is the protection,upliftment,and scientific management of biodiversity to maintain it at an optimum level and derive sustainable benefits for present as well as future generations.
Reasons for Conserving Biodiversity:
There are three main categories of reasons for the conservation of biodiversity:
$1$. Narrowly utilitarian: Humans derive countless direct economic benefits from nature,such as food (cereals,pulses,and fruits),firewood,fiber,construction material,industrial products (tannins,lubricants,dyes,resins,and perfumes),and products of medicinal importance. More than $25\%$ of the drugs currently sold in the market worldwide are derived from plants,and $25,000$ plant species are used in traditional medicines.
$2$. Broadly utilitarian: Biodiversity plays a major role in ecosystem services provided by nature,such as:
$(i)$ Production of oxygen (e.g.,Amazon forest produces $20\%$ of the total oxygen in the earth's atmosphere).
$(ii)$ Pollination of flowers by bees,bumblebees,birds,and bats,which is essential for fruit and seed production.
$(iii)$ Control of floods and soil erosion.
$(iv)$ Aesthetic pleasures,such as watching flowers in bloom or walking through a forest.
$3$. Ethical Argument: Every species has an intrinsic value,even if it has no direct economic value to us. It is our moral duty to care for their well-being and pass on our biological legacy to future generations.

Medium
Write an explanatory note on In situ conservation.

Solution

(N/A) In situ (on-site) conservation is the conservation and protection of the whole ecosystem and its biodiversity at all levels to protect threatened species.
However,it is not economically feasible to conserve all biological wealth in all existing ecosystems.
- Methods used in in situ conservation are:
- Biodiversity hotspots: Biodiversity hotspots are an approach for in situ conservation.
Eminent conservationists have identified certain regions for maximum protection; these regions are called biodiversity hotspots.
These are regions with very high levels of species richness,a high degree of endemism (species confined to a region and not found anywhere else),and accelerated habitat loss.
Initially,$25$ biodiversity hotspots were identified.
- Now,there are $34$ hotspots all over the world.
- Three hotspots are in India,i.e.,Western Ghats and Sri Lanka,Indo-Burma,and Eastern Himalaya.
- If all biodiversity hotspots are put together,they cover less than $2 \%$ of the earth's land area but harbour extremely high diversity.
- Ongoing mass extinction could be reduced by $30 \%$ through strict protection of these hotspots.
- Protected Areas: Protected areas are dedicated areas for the protection and maintenance of ecologically unique and biodiversity-rich regions. Protected areas are classified as:
$(a)$ National Parks: These are government-maintained areas reserved for the betterment of wildlife,where activities such as cultivation,grazing,forestry,and habitat manipulation are not allowed.
- The first National Park established in India in $1936$ was Hailey's National Park (now Jim Corbett National Park).
$(b)$ Sanctuaries: These are tracts of land with or without lakes where wild animals/fauna can take refuge without being hunted.
- Other activities like the collection of forest products,harvesting of timber,private ownership of land,etc.,are allowed here.
$(c)$ Biosphere Reserves: These are large tracts of protected land with multiple uses,preserving the genetic diversity of the ecosystem by protecting wildlife,the traditional lifestyles of tribals,and varied plant and animal genetic resources.
- They have been set up under the $MAB$ (Man and the Biosphere) programme of $UNESCO$.

Medium
Describe various methods used in 'In situ conservation'.

Solution

(A) In situ (on-site) conservation involves the protection and conservation of entire ecosystems and their biodiversity at all levels to safeguard threatened species.
Since it is not economically feasible to conserve all biological wealth in every existing ecosystem,specific strategies are employed:
$1$. Biodiversity Hotspots: These are regions identified for maximum protection due to very high levels of species richness,a high degree of endemism (species confined to a specific region),and accelerated habitat loss.
- Currently,there are $34$ hotspots globally.
- India hosts three hotspots: Western Ghats and Sri Lanka,Indo-Burma,and the Eastern Himalayas.
- Collectively,these hotspots cover less than $2 \%$ of the Earth's land area but harbor extremely high diversity. Strict protection of these areas could reduce ongoing mass extinction by nearly $30 \%$.
$2$. Protected Areas: These are dedicated regions for the maintenance of ecologically unique and biodiversity-rich areas.
- $(a)$ National Parks: Government-maintained areas reserved for wildlife protection where activities like cultivation,grazing,and forestry are prohibited. The first national park in India was Hailey National Park (established in $1936$).
- $(b)$ Wildlife Sanctuaries: Tracts of land where wild animals can take refuge without the threat of hunting. Activities like the collection of forest products and timber harvesting are permitted here.
- $(c)$ Biosphere Reserves: Large,multi-purpose protected areas designed to preserve genetic diversity,protect wildlife,and maintain the traditional lifestyles of tribal communities.

141
MediumMCQ
Which method is used for the preservation of gametes of threatened species?
A
Deep freeze
B
Cryopreservation
C
Plant tissue culture
D
Lyophilization

Solution

(B) Cryopreservation is a technique used to preserve gametes,seeds,embryos,and tissues of threatened species at very low temperatures.
In this method,biological materials are stored in liquid nitrogen at $-196^{\circ}C$.
This process halts metabolic activities,allowing the samples to be stored for long periods without degradation.
Therefore,the correct option is $B$.
142
MediumMCQ
Which of the following is not an example of $in-situ$ conservation?
A
Wildlife sanctuaries
B
Wildlife safari parks
C
Zoological parks
D
Botanical gardens

Solution

(C) Conservation strategies are broadly classified into two types: $in-situ$ (on-site) and $ex-situ$ (off-site) conservation.
$In-situ$ conservation involves protecting the whole ecosystem and its biodiversity in its natural habitat, such as National Parks, Wildlife Sanctuaries, and Biosphere Reserves.
$Ex-situ$ conservation involves placing threatened animals and plants in special settings where they can be protected and cared for, outside their natural habitats.
Zoological parks, botanical gardens, and wildlife safari parks are examples of $ex-situ$ conservation.
Therefore, wildlife sanctuaries are the only option listed that represents $in-situ$ conservation, making the question ask for the exception among the choices provided. However, since the question asks which is $NOT$ $in-situ$, and $C$ and $D$ are definitely $ex-situ$, usually, in such multiple-choice questions, $ex-situ$ sites are the answer. Given the standard classification, Zoological parks $(C)$ and Botanical gardens $(D)$ are classic $ex-situ$ examples. Wildlife safari parks are also $ex-situ$.
