Conservation Reserves:

• It is a state-owned area adjacent to National Parks and sanctuaries for the protection of the landscape, seascape, and habitat of fauna and flora. It is overseen by a Conservation Reserve Management Committee.
• After consulting with local communities, the State Government may declare any area owned by the Government as a conservation reserve.
• Tiruppadaimarathur conservation reserve in Tirunelveli, Tamil Nadu is the country’s first conservation reserve.
• The village community made an effort to protect the birds that nest in their village and acted to establish a conservation reserve.
• The rights of people who live within a Conservation Reserve are unaffected.
• There are 100 existing conservation reserves in India, covering an area of 4927.28 km2, or 0.15 percent of the country’s geographical area.

Community Reserves:

• The State Government may designate any community land or private land as a Community Reserve if the members of that community or individuals involved agree to offer such areas for the protection of fauna and flora, as well as their traditions, cultures, and practices.
• The designation of such an area aims to improve the socioeconomic conditions of the people who live in such areas while also conserving wildlife.
• A Community Reserve Management Committee oversees the Reserve.
• Where a community or an individual has volunteered to conserve wildlife and its habitat, the State Government may declare the area as community land by notification.

• In reserved forests, local people are prohibited, unless specifically allowed by a Forest Officer in the course of the settlement.
• In reserved forests, activities like lumbering, grazing and hunting are banned.
• The first reserve forest in India was Satpura National Park in Madhya Pradesh.

Protected Forests:

• The State Government is empowered to constitute any land other than reserved forests as protected forests over which the Government has proprietary rights and the power to issue rules regarding the use of such forests.
• This power has been used to establish State control over trees, whose timber, fruit or other non-wood products have revenue-raising potential.
• In protected forests, sometimes the local community has got the rights for activities like hunting and grazing as they are living on the fringes of the forest because they sustain their livelihood wholly or partially from forest resources or products.

Village forest:

• Village forests are the one in which the State Government may assign to ‘any village community the rights of Government to or over any land which has been constituted a reserved forest’.

Note:

In-situ conservation:

• The in-situ approach includes the protection of a typical ecosystem through a network of protected areas on land or sea.
• When we conserve and protect the whole ecosystem, its biodiversity at all levels is protected. E.g., we save the entire forest to save the tiger. This approach is called in in-situ (on site) conservation.
• The biosphere reserves, national parks and wildlife sanctuaries are part of in-situ conservation.
• In India, ecologically unique and biodiversity-rich regions are legally protected as biosphere reserves, national parks, sanctuaries, reserved forests, protected forests and nature reserves.

Ex-situ Conservation:

• When there are situations where an animal or plant is endangered or threatened and needs urgent measures to save it from extinction, ex-situ (off-site) conservation is the desirable approach.
• In this approach, threatened animals and plants are taken out from their natural habitat and placed in special setting where they can be protected and given special care.
• Zoological parks, botanical gardens, wildlife safari parks and seed banks serve this purpose.
• There are many animals that have become extinct in the wild but continue to be maintained in zoological parks.
• In recent years ex-situ conservation has advanced beyond keeping threatened species.
• Now gametes of threatened species can be preserved in viable and fertile condition for long periods using cryopreservation techniques.
• Eggs can be fertilized in vitro, and plants can be propagated using tissue culture methods.
• Seeds of different genetic strains of commercially important plants can be kept for long periods in seed banks.
• The national gene bank at National Bureau of Plant Genetic Resources (NBPGR), Delhi is primarily responsible for conservation of unique accessions on long-term basis, as base collections for posterity, predominantly in the form of seeds.

Black-Naped Pheasant pigeon:

• Before the recent rediscovery in September 2022, Black-Naped Pheasant-Pigeon was first and last seen in 1882.
• It is a large, terrestrial pigeon having black and orange feathers and red eyes.

• The species is endemic to Fergusson Island in Papua New Guinea.
• It split from the species Otidiphaps nobilis, which diverged from all other species some 26.1 million years ago. Otidiphaps nobilis is part of the Columbidae family, which diverged from all other species during the Paleogene period, some 32.7 million years ago.
• The population is dwindling because of the loss of forest habitats, which is caused by the logging and conversion for subsistence agriculture gardens. Conservation activities of the species’ habitat are few and far between.
• In July 2021, though the species’ population is undetermined, it was listed as a critically endangered species by the International Union for Conservation of Nature (IUCN), with an estimated population of 50 to 249 birds.

Important Bird Area:

• An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations.
• IBA was developed and sites are identified by Birdlife International.
• There are over 13,000 IBAs worldwide.
• These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat.
• Forty percent of India’s IBAs fall outside the Protected area network and thus form an important tool for landscape-level conservation planning.
• In the United States the Program is administered by the National Audubon Society.
• Often IBAs form part of a country’s existing protected area network, and so are protected under national legislation.
• Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries.
• Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking.

Length of the 1st train = 105 m

Length of the 2nd train = 90 m

Relative speed of the trains,

= 45 + 72 = 117 kmph

= ((117*5)/18)

= 32.5 m/sec

Time taken to cross each other,

= (Length of 1st train + length of 2nd train)/relative speed of the trains

Each one coded with either a single colour or unique two-colour pair.

Therefore, total number of ways = n + ⁿC₂

Let’s analyze the answer choices.

If there are 5 different colors, the number of codes that can be formed is 5C1 + 5C2 = 5 + 10 = 15, which is not sufficient for the 20 different chemicals.

If there are 6 different colors, the number of codes that can be formed is 6C1 + 6C2 = 6 + 15 = 21, which IS sufficient for the 20 different chemicals. Therefore, we need at least 6 different colors.

Minimum number of different colour needed to code all 20 chemicals will be 6

Solution (c)

Narayan’s saving and rent = 1000 + 1800 = Rs. 2800

Let his monthly income be Rs. 100

30% of his income he spent on education i.e. Rs. 30

Remaining = 100 – 30 = 70

50% of remaining on food = (70*50)/100

Rs. 35

Now, that 35 must be equal to his saving and rent i.e.

35 = 2800 then,

1 = (2800)/35

100 = (2800*100)/35

= Rs. 8000

So, his income = Rs. 8000
