Practice questions
Q1Consider the following statements about interpreting changes in tree cover: 1. Tree cover may include plantations and trees outside recorded forest areas. 2. Therefore, every increase in tree cover necessarily proves recovery of native forest diversity and wildlife habitat. Which of the statements given above is/are correct? Select the correct answer using the code given below.
Statement 1 is correct and Statement 2 is incorrect. Tree-cover totals can be affected by plantations, orchards and trees outside recorded forests. Canopy gain alone does not reveal native species diversity, stand age, rights status or wildlife value, so it cannot by itself prove ecological recovery.
Q2With reference to forests in India, consider the following statements: 1. A forest type is an ecological class based on factors such as climate, altitude, species and moisture. 2. A canopy-density class is a legal category created by the Indian Forest Act. 3. Recorded Forest Area is land recorded as forest in government records, irrespective of whether its present canopy is dense. Which of the statements given above are correct? Select the correct answer using the code given below.
Statements 1 and 3 are correct. Forest type answers an ecological question, while Recorded Forest Area is a legal-record category. Canopy-density classes are remote-sensing measurement categories and may occur inside or outside recorded forest land; they are not legal categories under the Indian Forest Act.
Q3Consider the following statements about mangroves: 1. Their distribution is controlled more by tidal, saline and muddy coastal conditions than by rainfall alone. 2. They help trap sediments, support fisheries and buffer cyclone impacts. Which of the statements given above is/are correct? Select the correct answer using the code given below.
Both statements are correct. Mangroves depend strongly on the tidal water regime and saline, muddy coastal settings. They trap sediments, support fisheries and provide partial buffering against cyclones and coastal erosion.
