Azadirachta indica A.Juss. Main specimen
{ Ecology & Distribution }

  • Ecology :
    Azadirachta indica is said to grow "almost anywhere" in the lowland tropics. It quickly dies in waterlogged soils.
    Azadirachta indica requires large amounts of light, but it tolerates fairly heavy shade during the first few years. (Orwa C, Mutua A., Kindt R., Jamnadass R., Anthony S., 2009, Agroforestree Database: a tree reference and selection guide).
    Ideal conditions for Azadirachta indica are well-drained, deep, sandy soils and annual rainfall between 450 and 1500 mm. (Krishen, 2006, Trees of Delhi)
  • Distribution :
    "There is much confusion in the literature about the natural distribution of Azadirachta indica. It is considered to be native to dry areas in Afghanistan, Pakistan, India, Sri Lanka, Bangladesh, Myanmar and China (Abdulla, 1972; Tewari, 1992; Vietmeyer, 1992; Gupta, 1993).
    It is cultivated as well as naturalized in Thailand, Malaysia and Indonesia. The World Agroforestry Centre (2002) reports that it may have originated in Myanmar and from there became naturally distributed across the Indian subcontinent. More recently it has been planted in Peninsular Malaysia and Singapore, the Philippines, Australia, Saudi Arabia, tropical Africa, the Caribbean, and Central and South America.
