Answer: Australia
Notes: Six years after Cyclone Gaja, farmers in Vedaranyam, Tamil Nadu, are preparing for their first harvest of casuarina (savukku) plantations. Casuarina, native to Australia, was introduced in India in the 19th century and is also known as kattadi. There are four cultivated species: Casuarina equisetifolia, glauca, cunninghamaina, and junghuniana. Its nitrogen-fixing ability and adaptability to diverse soil and climates make it ideal for commercial and environmental planting. Casuarinas grow well in tropical, subtropical, and Mediterranean regions, thriving in temperatures from 10°C-33°C and rainfall of 700-2000 mm.
