FURTHER INF Scientific synonyms: A. polyacantha, A. campylacantha, Mimosa suma, M. catechu. Cutch tree occurs naturally in mixed deciduous forests and savannas of lower mountains and hills. In the sub-Himalayan tract from the Indus to Assam, it is found at elevations up to 1000-1500 m. In Australia, it occurs at altitudes from sea level to 520 m. It prefers sites with a high water table. Some places it is cosidered a most undesirable tree. It spreads rapidly on fallow land and in pasture, particularly on low-lying fertile alluvial soil along drainage lines, and is expensive and difficult to eradicate. In India, the yield of heartwood range between 50-75 m3/ha giving a yield of cutch about 4-6 t/ha.
