Environment & Biodiversity MCQs

Notes:
Lawachara National Park (LNP) is located at Kamalganj Upazila, Maulvi Bazar District of Bangladesh and covers an area of 12.5 km2. It is a major national park and nature reserve in Bangladesh. There are 460 species, of which 167 species are plants, 4 amphibian species, 6 reptile species, 246 bird species, 20 mammal species, and 17 insect species. The park is considered of critical importance because the last viable population of critically endangered Western Hoolock Gibbons survive here.

Notes:
Pench National Park is located in the state of Madhya Pradesh and Maharashtra. It was established in the year 1975. In the year 2011, it bagged the “Best Management Award”. The Project Tiger Scheme was launched in 1992.

Notes:
Kalka is in Panchkula Haryana and shimla all of you know. Kalka Shimla Railway spreads in Haryana and Himachal Pradesh,
Valley of Flowers National Park is located in Uttarakhand,
Mountain Railways of India are in Darjeeling,
Sundarbans National Park isn West Bengal and
Champaner-Pavagadh Archaeological Park is in Gujarat.

Notes:
On 29 October 2010, some 18,000 participants representing the 193 Parties to the Convention on Biological Diversity (CBD) and their partners closed the Nagoya Biodiversity Summit by adopting historic decisions that will permit the community of nations to meet the unprecedented challenges of the continued loss of biodiversity compounded by climate change.

Notes:
IUCN protected area management categories classify protected areas according to their management objectives. They are la Strict Nature Reserve, Ib Wilderness Area, II National Park, III Natural Monument or Feature, IV Habitat/ Species Management Area, V Protected Landscape/ Seascape, VI Protected area with sustainable use of natural resources.

Notes:
The transition zone where two communities or biomes meet and intergrade is called an ecotone. Ecotone may vary in range starting from small agricultural field to large forest.  

Notes:
The taiga is the largest terrestrial biome and covers much of the northern regions of the world. It is dominated by conifers, and the landscape is dotted with lakes, ponds, and bogs. The taiga is characterized by heavy snow fall with large mammals like moose and elk and lots of insects and birds in the summer.

Notes:
As per the ambient noise standards, that have been notified for different categories like, industrial, commercial and residential areas and silence zones etc, for residential areas, 55 dB (A) Leq during ‘day time’ and 45 dB (A) Leq during ‘night time’ for residential areas have been fixed. Leq is a symbol that represents “Equivalent Continuous Noise Level”. Usually the signal that you are measuring is varying in amplitude.Leq noise levels are logarithmic (dB) values and cannot be added directly. A doubling of sound level results in a measured increase of 3 dB, four identical sources in a room would increase the noise level by 6 dB and so on.

Notes:
After United Kingdom, the Republic of Ireland has officially become the 2nd country in the world to declare a climate and biodiversity emergency. It happened after the Oireachtas (Irish parliament) report on Climate Action was accepted by the government and opposition parties without a vote. An amendment to a parliamentary report declaring a climate emergency and calling on parliament to examine how the Irish government can improve its response to the issue of biodiversity loss was accepted. Britain’s parliament became the first in the world to declare a climate emergency, passing the largely symbolic motion on May 1. The step followed 11 days of street protests in London by the Extinction Rebellion environmental campaign group.

Notes:
Sulfur dioxide and nitrogen oxides can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
