Result
Your answer: —  Â·  Correct: B
Explanation

The correct answer is (b) It tends to reduce the biodiversity in the area in which it grows.

Prosopis juliflora (commonly known as vilayati babool or mesquite) is an invasive alien species originally from Central and South America. It was introduced in India during the British era for afforestation of arid regions. Key concerns include:

  • It is a highly aggressive invasive species that displaces native vegetation
  • It reduces biodiversity by forming dense monoculture thickets
  • It depletes groundwater with its deep root system
  • It has invaded grasslands and wetlands, threatening native flora and fauna including the habitat of the Great Indian Bustard in Rajasthan
  • It has been a major concern in Tamil Nadu, Rajasthan, Gujarat, and other arid/semi-arid states

Multiple court cases and government initiatives have sought to address the ecological damage caused by this invasive species.
