Transplantation also requires trimming of roots. But not all indigenous trees r good at regenerating their root systems;

While rarely younger trees of some species, Pongamia & Ficus can tolerate transplantation, other common native species such as dhok/palash, Siris cannot.

If tree loses its canopy, it loses the transpiration function, the process by which it carries moisture fm the roots to leaves & dries out. A weak underfed tree cannot perform its ecological function. If the ability to do this is compromised in the process, tree is lost!

Transplanting any tree with a girth of more than 80-90 cm is not advisable as tree cannot bear the shock & will eventually die. Soil type too is an imp consideration. A tree growing on #DelhiRidge will not easily acclimatise to soil in #YamunaFloodplain as the ecosystem is diff.
