Which of the following National Parks is unique in being a swamp with floating vegetation that supports rich biodiversity?
Keibul Lamjao National Park is a national park in the Bishnupur district of the state of Manipur in India. It is 40 km² in area, the only floating park in the world, located in North East India, and an integral part of Loktak Lake. The national park is characterized by many floating decomposed plant materials locally called phumdis. To preserve the natural refuge of the endangered Manipur Eld's deer or brow-antlered deer (Cervus eldi eldi), or sangai also called the dancing deer, listed as an endangered species by IUCN. The park, which was initially declared to be a sanctuary in 1966, was subsequently declared to be a national park in 1977 through a gazette notification.
With reference to an organization known as ‘Birdlife International’ which of the following statements is/are correct?
1. It is a Global Partnership of Conservation Organizations.
2. The concept of ‘biodiversity hotspots’ originated from this organization.
3. It identifies the sites known/referred to as ‘Important Bird and Biodiversity Areas’.
Select the correct answer using the code given below.
Statement 1 is correct: BirdLife's Important Bird and Biodiversity Area (IBA) Programme aims to identify, monitor, and protect a global network of IBAs for the conservation of the world's birds and other wildlife. Statement 2 is incorrect: The British biologist Norman Myers coined the term biodiversity hotspot in 1988 as a biogeographic region characterized both by exceptional levels of plant endemism and by serious levels of habitat loss. Statement 3 is correct: One of their key activities involves identifying and designating Important Bird and Biodiversity Areas (IBAs), critical sites for bird conservation that also contribute significantly to overall biodiversity.
With reference to ‘dugong’, mammal found in India, which of the following statements is/are correct?
1. It is a herbivorous marine animal.
2. It is found along the entire coast of India
3. It is given legal protection under Schedule 1 of the Wildlife (Protection) Act, 1972.
Select the correct answer using the code given below.
Statement 1 is correct: The Dugong is a herbivorous marine animal. Dugongs are marine mammals that feed on seagrass meadows. Statement 2 is incorrect: While once more widespread, dugong populations are now concentrated in specific areas. They are primarily found in -The Gulf of Mannar and Palk Bay off the coast of Tamil Nadu -The Andaman and Nicobar Islands -The Gulf of Kutch Statement 3 is correct: It is given legal protection under Schedule 1 of the Wildlife (Protection) Act, 1972.

Consider the following international agreements:
1. The International Treaty on Plant Genetic Resources for Food and Agriculture
2. The United Nations Convention to Combat Desertification
3. The World Heritage Convention
Which of the above has/have a bearing on the biodiversity?
The International Treaty on Plant Genetic Resources for Food and Agriculture focuses on ensuring the conservation and sustainable use of plant genetic resources for food and agriculture. This directly impacts biodiversity as it aims to protect the variety of plant species crucial for food security and ecosystem health. The United Nations Convention to Combat Desertification addresses land degradation in arid, semi-arid, and dry sub-humid areas. Desertification can significantly reduce biodiversity by destroying habitats and reducing plant and animal life. By working to combat desertification, this convention indirectly protects biodiversity. The World Heritage Convention focuses on preserving cultural and natural heritage sites. Conservation natural heritage sites may contribute to biodiversity conservation.
Thus 'D' is the correct answer.
What are the benefits of implementing the ‘Integrated Watershed Development Programme’?
1. Prevention of soil runoff
2. Linking the country’s perennial rivers with seasonal rivers
3. Rainwater harvesting and recharge of the groundwater table
4. Regeneration of natural vegetation
Select the correct answer using the code given below.
Statement 1 is correct: Prevention of soil runoff IWDP promotes practices that reduce soil erosion, protecting valuable topsoil and improving land fertility. Statement 2 is incorrect: Linking perennial and seasonal rivers While water resource management is a part of IWDP, it doesn't focus on physically linking separate river systems. The National River Linking Project is a separate project to interlink rivers. Statement 3 is correct: Rainwater harvesting and groundwater recharge IWDP encourages rainwater conservation techniques, allowing more water to infiltrate the ground and replenish aquifers. Statement 4 is correct: Regeneration of natural vegetation IWDP often involves planting trees and promoting sustainable land management practices, leading to increased vegetation cover.
