Concept:Forest cover percentage is the ratio of total forest area to the total geographical area of a state, expressed as a percentage.
Explanation:Bihar has a total geographical area of 94,163 sq km.
As per the 2019 assessment, the total forest cover of Bihar is 7,305.99 sq km.
This includes very dense forest (333.13 sq km), moderately dense forest (3,280.32 sq km), and open forest (3,692.54 sq km).
To calculate the percentage:
Percentage=941637305.99​×100=7.76%The options given are 7.27%, 6.87%, and 3.21%. None of these match the calculated value of 7.76%.
Therefore, the correct choice is "None of the above".
For context, the all-India average forest cover is 23.3%. Bihar’s forest cover is significantly lower.
Only 11 out of 38 districts in Bihar have natural forests, including Kaimur, West Champaran, Rohtas, Gaya, and others.
West Champaran has the densest forests where sunlight rarely reaches the ground.
The reserved, protected, and unclassed forests account for 10.08%, 89.91%, and 0.01% of the recorded forest area, respectively.
Major forest types in Bihar are Tropical Dry Deciduous and Tropical Moist Deciduous.
The total carbon stock of forests in Bihar is 55.397 million tonnes, which is 0.78% of the country’s total forest carbon.
